A vehicle diagnostic scan dated 04/15/2026 at approximately 88,502 miles showed a stored transmission electronics fault: P084100, described as “Transmission fluid pressure sensor/switch A range/performance,” with status listed as passive/sporadic. This indicates a transmission / powertrain control concern involving the transmission fluid pressure sensor, transmission electronics, wiring, control logic, pressure monitoring, or related powertrain components. The vehicle also has prior transmission/powertrain history, including a March 2023 transmission-pan-gasket concern documented in service records, so this later transmission electronics fault is being reported in that broader powertrain context. This is being reported as a safety concern because a transmission fluid pressure sensor or transmission-control fault can affect shifting, drivability, delayed engagement, slipping, harsh shifting, limp mode, reduced power, drivetrain damage, or loss of propulsion while driving. Even if the fault is intermittent, a transmission-control issue may create an unsafe condition if it occurs in traffic or during acceleration, merging, turning, or normal driving. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and the diagnostic scan report, transmission-related records, service records, manufacturer communications, and related communications are available if requested.

A vehicle diagnostic scan dated 04/15/2026 showed electrical communication faults involving vehicle control modules. The scan showed U014100, described as “Lost Communication With Body Control Module ‘A’,” with status listed as passive/sporadic. The scan also showed U112100, described as “Data bus message missing,” with status listed as active/static. This is being reported as a safety concern because body-control module, gateway, and data-bus communication faults can affect vehicle electrical functions, warning systems, access/locking systems, lighting or body-control functions, driver information, and other vehicle systems that rely on module communication. The concern is especially important because the vehicle has had multiple intermittent electrical/body-control symptoms, including fuel-door/tank-flap electrical faults and other reported intermittent vehicle electrical concerns. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and the diagnostic scan report, electrical-system records, service communications, and related repair records are available if requested.

An Audi dealer installed 245/40R18 93H tires on this 2018 Audi A4, while the vehicle placard/specification requires 245/40R18 97H. The lower load index reduces capacity from 1,609 lb per tire to 1,433 lb per tire, approximately 704 lb total across four tires. This creates a safety risk because load-rated tires affect vehicle stability, heat buildup, braking, steering/cornering, suspension loading, and tire failure/blowout risk. After discovering the mismatch, the concern was reported to the dealer and Audi, but the dealer stated the 93H tires were acceptable rather than providing a safety-based correction. No crash, fire, injury, or fatality occurred. This complaint is being submitted because the vehicle may have been operated with under-rated tires and because the issue can affect handling, braking, tire durability, suspension/wheel components, and safe vehicle control. Tire/repair-order records, door-jamb placard evidence, load-index comparison evidence, and dealer communications are available.

The rear-view camera intermittently fails to engage when the vehicle is shifted into reverse. When the camera does display, the image sometimes shows horizontal glitch lines/artifacts. This affects backing visibility and parking safety and creates a risk of collision with pedestrians, objects, vehicles, or property. The concern was reported to Audi service along with other electrical/driver-assistance symptoms, suggesting a possible camera, wiring, module, signal-processing, or broader electrical fault. No crash, fire, injury, or fatality occurred. This complaint is being submitted because the rear camera/reverse display is a backing-safety system and the intermittent failure is unpredictable. The vehicle/component is available for inspection, and photo/video evidence and service communications are available.

The vehicle displayed a low coolant warning and the coolant reservoir was low. Audi dealer service records dated on or about 02/14/2025 document the concern as: “client states low coolant warning was on, coolant reservoir is low, diagnose and advise.” The dealer performed coolant-related work involving the thermostat gasket / coolant hoses or connections to the coolant reservoir, ran the vehicle to operating temperature, and rechecked. The concern is being reported because the coolant loss/refill issue continued or remained unresolved afterward. The exact source of coolant loss is unknown, but it may involve the water pump, thermostat, coolant reservoir, coolant hoses/pipes, pressure loss, internal coolant leak, or coolant loss that evaporates before leaving visible residue. This is a safety concern because coolant loss can lead to overheating, warning messages, limp mode, loss of propulsion, engine damage, steam/smoke, or stall risk while driving. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and Audi service records, coolant-system communications, photos, and water-pump/coolant-related documents are available.

Visible wiring has become exposed in the windshield/A-pillar area. There is no airbag/SRS warning light at this time, and I am not able to determine from visual inspection whether the exposed wiring is related to the restraint system. However, this is a safety-sensitive area because it can contain or route electrical wiring near trim, sensors, and safety-system areas. Exposed or unsecured wiring in this area may create a risk of electrical short, damaged wiring, impaired signal integrity, loose trim, moisture intrusion, or safety-system malfunction. The concern was reported as part of broader electrical and safety-related issues. No crash, fire, injury, or fatality occurred. This complaint is being submitted because exposed wiring in the A-pillar/windshield-pillar area is not normal and should be inspected to determine whether the wiring, trim, connector routing, or related electrical/safety components are compromised. The vehicle/component is available for inspection, and photo evidence and service communications are available.

The sunroof has a recurring mechanical/electrical malfunction. During operation, the sunroof binds and makes a loud popping or cracking noise, and the rubber seal became torn or damaged. This suggests a possible track, guide, cable, motor, regulator, frame, seal, or alignment failure. This is being reported as a safety concern because a binding or popping sunroof can distract the driver, allow water intrusion into electrical areas, worsen into glass/track/frame failure, or create a risk of loose roof components while the vehicle is in use. The issue was reported to Audi service and was not fully resolved or documented to my satisfaction. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and photos, video stills, service communications, and repair records are available.

The exterior side mirrors have intermittent electrical/memory malfunctions. When locking the vehicle, the side mirrors begin to fold, pause or glitch briefly, and then continue folding. Separately, when the vehicle is shifted into reverse, the right-side mirror tilts downward to assist with backing/parking, but when shifted back to drive or park, the mirror does not reliably return to its original saved position and requires manual readjustment. This is being reported as a safety concern because exterior mirror position affects rearward and side visibility, backing visibility, lane-change awareness, and the driver’s ability to maintain proper mirror alignment. An intermittent mirror control, folding, memory, or tilt malfunction may indicate an electrical, motor, control-module, wiring, switch, or mirror-memory issue. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and service communications, issue lists, photos/video if available, and related electrical-system records are available.

The fuel filler door/gas door intermittently fails to open, preventing normal access to the fuel filler area. This appears to involve the fuel door latch, release mechanism, lock actuator, body component, electrical control, or related wiring/module issue. This is being reported as a safety concern because inability to open the fuel door can prevent refueling when fuel is low. If the vehicle cannot be refueled, it can create a stranding risk or loss-of-propulsion risk, including in traffic, at night, on a highway, or in an unsafe location. The issue also creates driver distraction and uncertainty because refueling access is not reliable. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and photos/video, service communications, and repair records are available if requested.

The engine oil level has been gradually dropping and has required monitoring and/or adding oil between normal service intervals. The exact source is unknown. It may involve abnormal oil consumption, an external oil leak, internal engine oil consumption, PCV/oil separator issue, turbo-related oil consumption, gasket/seal issue, or oil loss that is not leaving an obvious visible puddle. This is being reported as a safety concern because low engine oil or abnormal oil loss can lead to low oil pressure, warning messages, engine overheating or damage, smoke, oil contacting hot engine/exhaust components, limp mode, stalling, or loss of propulsion while driving. The issue should be inspected rather than treated as normal maintenance unless a proper diagnosis confirms normal operation. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and oil-level/refill records, repair records, photos, receipts, and service communications are available if requested.

The vehicle intermittently gives a false proximity/collision warning while stationary or while maneuvering at low speed. The sensors beep and display a warning on the screen as if an object is about to hit the vehicle, even when nothing around the vehicle has changed and no object is present. This appears to involve the parking/proximity warning system, sensor system, control module, wiring, calibration, or broader electrical/driver-assistance system. This is being reported as a safety concern because false collision/proximity warnings can distract the driver, reduce trust in the vehicle’s warning systems, cause unnecessary braking or hesitation, and may indicate a malfunction in the systems used for parking, low-speed maneuvering, and obstacle detection. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and service communications, issue lists, photos/video if available, and related electrical/driver-assistance records are available if requested.

The short-term MPG / fuel-consumption display gives illogical and inconsistent readings. The display can show a significant drop in short-term fuel economy after the vehicle has been parked, locked, and not running, as if the system is incorrectly factoring parked/off time into the MPG calculation. This suggests a possible fault in the onboard computer, instrument cluster, fuel-consumption calculation, sensor input, software, ECU/module logic, or related electrical system. This is being reported as a safety concern because inaccurate fuel-consumption or range-related information can mislead the driver about fuel usage and remaining range, and it may indicate a broader vehicle electrical/computer/sensor malfunction. The concern is also part of a broader pattern of electrical or driver-information issues, including other intermittent warnings and display-related concerns. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and photos/video of the display, service communications, issue lists, and related electrical-system records are available if requested.

The vehicle is subject to a Passenger Occupant Detection System / PODS safety recall involving the front passenger seat occupant-detection system and passenger airbag status. The concern is that the system may incorrectly detect whether a passenger is seated and may switch off or affect the front passenger airbag when the seat is occupied. This is being reported because the recall remedy was not completed, was delayed, was not properly resolved, or the concern remains unresolved. A malfunctioning passenger occupant detection system can affect whether the passenger airbag deploys as intended in a crash. The issue involves the airbag system, front passenger seat occupant detection, related sensors/modules, and related electrical components. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and Audi recall documents, service records, communications, and any warning-light or passenger-airbag-status evidence are available if requested.

The vehicle has a recurring interior rattle / loose-trim concern involving interior panels, trim, speaker/subwoofer area, rear shelf, dashboard area, or related mounting components. The noise is not merely a comfort concern if it is caused by a loose component, fastener, grille, panel, or speaker housing that may move, worsen, detach, or distract the driver. This is being reported as a safety concern because loose interior trim or components can distract the driver, interfere with normal vehicle use, create uncertainty about whether a component is secured, and may indicate improper fastening, panel fitment, speaker/subwoofer mounting, or body/electrical component installation issues. If the affected trim is near safety-system areas, it should be inspected to confirm it does not affect wiring, restraint-system areas, visibility, or safe vehicle operation. No crash, fire, injury, or fatality occurred. The vehicle/component is available for inspection, and service records, TSB-related records, photos/video/audio, issue lists, and repair communications are available if requested.

I am reporting recurring safety-related defects on my 2018 Audi A4 involving Automatic Emergency Braking, Forward Collision Warning, Audi pre sense/front-collision functionality, and related electrical/driver-assistance reliability. The AEB/forward-collision system has shown two unsafe intermittent behaviors. At times it has failed to activate as expected when crash-mitigation assistance appeared reasonably available. At other times it has unexpectedly warned, jolted, or applied braking when there was no apparent vehicle, object, pedestrian, or hazard close to the car. Unexpected braking or false intervention can startle the driver, create rear-end collision risk, and reduce confidence in the system. Failure to activate can also increase forward-collision risk. The system was not intentionally disabled by me, and I am not aware of any driver-caused obstruction, modification, or normal explanation. The condition is intermittent and may not appear during a brief service visit or basic fault-code scan. This concern was reported through Audi/dealer service channels, including a documented repair request identifying the AEB system as malfunctioning and failing to activate as designed. A later dealer communication stated that there were no stored AEB faults and later clarified that no work was done on the AEB system, no inspection or verification of AEB operation was performed, and confirmation of operation would require an additional estimate. I am reporting unresolved safety status because intermittent active-safety failures or false interventions may not store permanent DTCs, and lack of stored faults is not complete safety verification. I have not received final written safety closure confirming inspection, calibration review, road-test verification, factory scan/freeze-frame review, module communication review, and technical verification. No crash, fire, injury, or fatality is being reported. The vehicle is available for inspection if requested.

This problem is extremely sporadic, and often remedies itself after car shut down, and sometimes require that the car sit for a period of time. I estimate the following issue happens ~1 time a month, or estimated 5% of the time. Weather (temperature specifically) does not appear to impact occurance. When reversing, at times the back up camera does not function properly. During these times, the parking sensors appear to work, but it's unclear if the emergency reverse automatic braking system is working. The backup camera issues present themselves in several different ways and are described below. 1) Scrolling view (think of an old time movie, where the image "scrolling" through the screen 2) Black, but not completely black, includes what appears to be interference (sometimes white pixels flash randomly throughout the screen) 3) Off color (almost like a color inversion), darks appear light, light colors appear dark, similar to how things when developing film in a dark room 4) Similar to #1 but instead it freezes, halfway through a scroll. Often times the picture is split, with the bottom on the top, and the top on the bottom, and a clear black line in the middle Opening and closing the trunk, tapping the camera, turning the parking sensor (and camera) off and on do not solve the issue when it happens. Neither does changing from R to P on the transmission lever. Issue always requires a restart, rarely does an immediate restart fix the issue. The tracking lines are also distorted when this happens. When not malfunctioning, camera system works perfectly. Recently, I came across NHTSA ID: 25V900000 which almost exactly describes my issues but my car is not included. I did recently ask the Dealer to look into it during my 40,000 mile service. They stated that no codes were in the system and they could further troubleshoot but the intermittent nature would likely result in no findings unless the issue is present on site.

The Audi MMI system began to spontaneously restart while driving after owning the car for a couple of years. It would power off and reboot at random intervals. It became more frequent and is both distracting and dangerous as you lose all navigation, and camera function while it reboots not to mention any telephone connection. This happens every couple of minutes and multiple times per drive. Took it to the dealer (Kendall Audi of Bend) and was told the MMI needed to be replaced. Spent approx. $2500 to have MMI replaced and now it has started happening again with the NEW MMI. There are MANY MANY other complaints with this same issue on Reddit and the Audi World Forum and it needs to be addressed by Audi.

Fortunately no catastrophic failure or accident occurred. At about 40,000k miles the rear spring mounts are significantly corroded and need replacing. This appears to be a galvanic reaction that occurs due to a design flaw which shortens the life of the critical mounts. I’m told one could fail imminently and the other is headed that way. Had this failed in use the damage would be significant and caused an accident. The service advisor said that Audi is aware of the short lifespan and has an improved version that will be used in the repair. I have a video of one of the mounts and will request the parts when repaired.

The all-wheel-drive clutch in the vehicle had to be replaced. The symptoms were heavy vibrations or thumping when starting to drive forward from a stop with the wheels turned in either direction. A dealership - New Country Audi of Greenwich - did the repair at a cost of $4,308.85 (including tax). This drivetrain failure occurred at less than 48,000 miles. The vehicle came with a 50,000 mile or 4 year warranty. Since it was in service for over 5 years, this defect was not covered under warranty. There is a Techical Service Bulletin on this issue, number 39 21 43 2059057/4 July 16, 2021. The dealer confirmed my issue was indeed the same as that addressed in the TSB. It seems to me that a major known issue occurring at less than 50,000 miles is a defect. I do not know if it is ultimately a safety hazard, but it seems it could become dangerous if not addressed. For reference, I am attaching the TSB and the repair invoice.

Water Pump prematurely failed. Upon self inspection, I noticed the coolant reservoir was below the minimum requirements. I asked the dealer to inspect, and they determined the cause was a faulty water pump. At around 50,000 miles, this water pump should not have failed under normal use. I am fortunate I self inspected, as continued use may cause premature engine failure due to overheating. Overheating would cause spontaneous vehicle operation failure during normal driving conditions, stalling the vehicle on a road or highway, putting myself and others at risk for impact.

The Audi Pre-sense engaged on 3 occasions going 50+ mph bringing the car to a complete stop when there was nothing in front if it and a car right behind me. I was lucky the car behind me did not collide. If it had been a semi truck and just as close as the car trailing me, they would not have been able to stop in time causing damage or death. The problem could not be confirmed by the Audi dealer who performed a vehicle scan and found no codes and could not reproduced it. I had the Pre-sense shut off. I reported this to the manufacture on 6/17/22. The Pre-sense red warning triangle displayed in the instrument panel as when it was engaging.

Forward Collision AvoidanceJun 2022 · ODI 11469403Details +Close −
The forward collision warning system (Audi PreSense) identified a shadow from an overpass as another car and alerted me to use the brakes. My car did figure out there was not another vehicle before performing an emergency brake. If the car had done an emergency brake I would have surly been rear ended on the highway. This is not the first time forward collision warning has activated due to a shadow on the road. I have not mentioned this to the dealer but have read of this happening to others that own Audi cars that use Audi PreSense. The Audi PreSense installed in my car utilizes the front facing camera only - there is not a forward facing radar system. There has never been a warning that that system is not functioning as intended.

Due to the AT&T 3G turndown, Audi of America is removing a critical safety feature from certain MY 2018 vehicles, with no solution offered to the vehicle owner except to pay an additional $650-$1000 out of pocket to install a retrofit device to restore some of these safety features. As sold, MY2017-2018 and certain MY 2019 Audi A4/A5/Q5/Q7 vehicles came with an emergency call feature, both automatic in the event of a severe accident, and manual. From the owners manual: "The vehicle electrical system initiates an automatic emergency call under certain circumstances, for example, if an airbag deploys. The LED in the emergency call button (2) blinks green. The emergency call is made. This cannot be cancelled." Because of the AT&T 3G Sunset, Audi of America is providing a retrofit kit to restore this emergency call functionality in the event of an accident. However, they are not providing this retrofit free to all customers. All MY2017 vehicles qualify for free installation and subscription to the new emergency call retrofit service. However, MY2018 and 2019 vehicles with an in- service date of before February 22, 2018 will have to pay for the installation and subscription to this service. Making owners of MY2018 vehicles pay to restore a critical safety feature that the vehicle was sold with is highly unethical and can lead to safety issues. Instead of an automated call to 911 during a severe accident, Audi of America is forcing owners of certain MY2018 vehicles to choose between paying $1000 + subscription fees for this critical safety service, or relying on owner's being conscious enough to use their own cell phones, which may not be the case during a severe accident. The decision by Audi of America to enforce an arbitrary in-service cutoff date of 2/22/2018 for MY2018 vehicles is highly illogical and unethical. All MY2017 vehicles, which are older and more likely to be out of warranty, qualify for the free update while MY2018 are subject to an arbitrary cutoff.

I received a message on my dashboard to turn the engine off and check the coolant when starting the vehicle each morning for the last two days. I brought the car into the Audi Dealership in Paramus/Fair Lawn, NJ. They stated the water pump was not working. I researched and found that a recall for ALL ROAD station wagons (Audi) had occurred for 2013-2017 for water pumps that could start a fire in the car. My car, although a 2018 model, was manufactured in January 19, 2018 (the beginning of 2018; recall noted for 2017)- water pump is defective with only 56,000 miles on it. My car was manufactured with defective water pump from prior year...... They paid for water pump part but made me pay for labor to put a replacement part in the car. AUDI should be liable for this..... there should be a recall in my year car because of the potential for fire with a defective water pump.

While driving the emergency parking brake engaged itself without warning or cause. This caused the vehicle to come to an abrupt stop. Luckily I was in a parking lot but if I had been in a high traffic area or intersection, it could’ve caused a collision. I had 2 passengers who witnessed this sudden bizarre event. There was nothing that could’ve caused this to happen. It scares me & now I’m worried this could happen again without warning. The sensor screen was beeping with a message to put my car in park before setting the brake. Made no sense why this happened.

INVOLVED IN A THREE CAR REAR-END ACCIDENT. I WAS THE VERY FRONT CAR (CAR 1, WHITE 2018 AUDI A4) WHICH WAS COMPLETELY STOPPED THAT TOOK THE LEAST FORCE OF THE IMPACT. CAR 2 (TESLA MEDEL S) WAS ALSO STOPPED BUT TOOK BRUNT OF FORCE FROM AT FAULT CAR 3 (DODGE SUV) WHO CAME BARRELING IN. MY CAR TOOK MINOR DAMAGE TO THE REAR YET MY 2018 AUDI A4'S COLLISION PROTOCOLS DISABLED MY CAR AND LEFT IT COMPLETELY UNDRIVEABLE. THE SEAT BELTS ALSO PULLED BACK AND LOCKED UP LEAVING ME UNABLE TO REBUCKLE MY SEAT BELT AFTER THE ACCIDENT. THIS MEANT I WAS STUCK IN THE MIDDLE OF A BUSY HIGHWAY UNABLE TO MOVE TO THE SHOULDER WITH NO PROTECTION BESIDES THE SHELL OF THE VEHICLE. AFTER THE FIRE DEPARTMENT ARRIVED 15 MINUTES LATER, THEY HAD TO SPEND CONSIDERABLE TIME READING THROUGH THE MANUAL TO FIGURE OUT HOW TO MANUALLY DISABLE MY BRAKES AND TOOK 4 FIREFIGHTERS (1 STEERING AND 3 PUSHING) TO PUSH MY CAR TO THE SHOULDER. MEANWHILE, THE AT FAULT DRIVER (CAR 3) WAS ABLE TO DRIVE AWAY FROM THE SCENE OF THE ACCIDENT AFTER COMPLETING POLICE ACTIVITIES. THE COLLISION PROTOCOL OF AUTOMATICALLY TIGHTENING SEAT BELTS, PUTTING ON HAZARD LIGHTS, DIALING ROAD-SIDE SERVICE, ROLLING DOWN WINDOWS PARTIALLY, AND BRAKING ITSELF WAS GREAT. HOWEVER, DISABLING THE CAR AND LEAVING THE SEAT BELTS UNUSABLE AFTERWARDS LEFT ME IN A DANGEROUS SITUATION THAT COULD HAVE BEEN EVEN A WORSE SECOND ACCIDENT. A FLATBED TOW TRUCK WAS CALLED IN BY AUDI ROADSIDE SERVICE AND OF COURSE THEY RECOMMENDED AN AUDI CERTIFIED COLLISION CENTER.
