I was driving down [XXX] from my house.My engine light started to flash.I tried to accelerate my car barely went 10 miles an hour.I got Home 2 minutes later.There was major knocking.I had the car towed to [XXX], Hyundai, the only code that is showing up on the diagnostics, is P1326 there is an open class action lawsuit for this exact code. For the rod bearing failure, Hyundai is denying the claim, saying there's a gap in maintenance history on a car. I didn't own yet when I bought the vehicle. It passed a 190 point inspection. There's no way there was anything wrong with this vehicle.I am under fifty thousand miles , and if I was on the highway , it could've been deadly i could not accelerate. No other lights were on in the vehicle, except for the flashing engine light.I have already reported to the better business bureau and they have sent it to arbitration. I have contacted the escalation department for Hyundai.They opened up to separate cases.The agent that was assigned to me didn't even get the code from [XXX], they just denied the claim without it.I have the emails to prove that I had to give it to her. I have.\n All my maintenance history, but as you can see from the text message from XXX Hyundai, they are requesting maintenance for a car that wasn't in my possession yet. They're asking for dates from a year before I had the car, I bought it through EchoPark. I have everyone on my side including fFdelity , as I tried to go through Fidelity and they said they couldn't approve the warranty because of the class action lawsuit against Hyundai for that exact manufacturer malfunction.

Forward crash avoidance system keeps activating causing the car to brake on it's own. This was previously fixed on my car once back in 2022 and now in 2026 it is happening again. I have been trying to communicate with Hyundai regarding additional years to current recall but their not going to even though they have known for years this was an issue and included older models than their current recall. This is not a one time issue this is the second time and until fixed it continously caused the vechile to randomly brake, it's going to get someone seriously injured or killed if they don't address it.

EngineMay 2026 · ODI 11735611Details +

My 2021 Hyundai Tucson has experienced repeated engine-related failures associated with a knock sensor (P1326) fault that causes the vehicle to enter limp mode and lose power while driving. This issue has occurred multiple times at approximately 15,000, 17,000, 41,000, and 90,000 miles and has resulted in four separate incidents requiring towing. During these events, the vehicle suddenly loses power and cannot maintain normal driving speed, creating a hazardous condition while in traffic. The vehicle has undergone multiple repair attempts, including an ECM update and three knock sensor replacements. Despite these repairs, the issue continues to recur and no root cause has been identified. Hyundai has not provided a permanent fix and has advised continued operation of the vehicle unless the issue occurs again. This ongoing condition presents a safety concern due to the risk of sudden loss of power while driving.

Electrical SystemApr 2026 · ODI 11734552Details +

In October 2025, while the vehicle was still under Hyundai’s 5-year warranty, an authorized Hyundai dealership diagnosed a significant electrical failure affecting the ABS/ESC system on my 2021 Hyundai Tucson. The vehicle was experiencing multiple dashboard warning lights, intermittent key fob malfunction, alarm system failure, and progressive electrical instability affecting safe operation. Dealer diagnostic trouble codes included C120001, C167581, and C164202, with technician notes stating “ABS sensor wiring harness fault found.” The dealership recommended replacement of the wiring harness, estimated at approximately $12,000, but no warranty repair was performed. Since the initial diagnosis, the condition has continued to worsen with additional warning lights and ongoing ABS/electrical system instability. The issue remains unresolved and continues to affect vehicle safety.

While driving on the freeway, my 2021 Hyundai Tucson SE (72,021 miles) suddenly and without warning lost power and entered limp mode. I was able to safely maneuver to the shoulder and exit the freeway. The check engine light came on and is currently flashing. I took the vehicle to AutoZone where code P1326 was retrieved. I then took it to Pep Boys for a full diagnostic where P1326 was the only code present. The Pep Boys report states the vehicle requires immediate attention. The vehicle remains in limp mode and the check engine light is flashing. The vehicle is not being driven as it cannot safely reach freeway speeds. I contacted Hyundai Customer Care and was assigned Case # XXX. I also contacted a Hyundai dealership who attempted to charge a 225 diagnostic fee despite P1326 being a known Hyundai defect covered under recall/service campaign.

Power TrainFeb 2026 · ODI 11716729Details +

The vehicle experienced a catalytic converter efficiency failure that was confirmed by an authorized dealership in January 2025. The dealer indicated the catalytic converter required replacement; however, the replacement was not performed, and the vehicle was returned to service with an unresolved emissions defect. Less than one year later, the vehicle developed recurring emissions system failure, loss of power, drivability issues, and repeated warning indicators. The vehicle is currently out of service while additional components, including oxygen sensors and spark plugs, are reported to be affected. The manufacturer is declining to replace the catalytic converter and is attributing the condition to oil consumption despite the prior unresolved emissions failure. The issue has been confirmed by dealership diagnostics and has resulted in prolonged loss of use of the vehicle. This appears to be a continuing engine and exhaust/emissions system defect that was not properly remedied when first identified and may affect safe operation of the vehicle.

Service BrakesNov 2025 · ODI 11699883Details +

The issue started just before my vehicle had 60,000 miles on it and only occurred every once and a while but, now it happens more often. When braking at low speeds my car makes a hissing/buzzing noise and the pedal goes soft. We got to a dealership when it had 60,420 miles on it. The dealership had it for two weeks saying they have never experienced anything like this issue before. They even contacted Hyundai Tech to help them. No warning lights ever came on and that was my concern. Finally after two weeks they said my tone ring on my driver's front side was bad and causing a false 0 reading. When I asked why the warning lights didn't come on they told me everything was working like should. Then after I pointed out that they said it was reading a false zero they were like no that must have been a typo its reading four miles under the rest and that's causing the abs system to activate. I'm from Ohio so I know what my abs sounds and feels like when it activates. It's a pulsating feeling not a soft pedal. When my abs truly activates my traction control light comes on. As I stated no lights have ever come on. This issue causes longer stopping times. There hasn't been any accidents because my wife and I try not to drive it. It's going to a third shop to try and figure out the issue. Yes the vehicle is available for inspection.

My family’s safety is at serious risk with my 2021 Hyundai Tucson, which I’ve owned only 55 days. This vehicle has stalled three times while driving, putting me and my two young children in immediate danger. Each time, the car operated normally until a flashing engine light appeared, RPMs spiked, and the vehicle suddenly lost all power—entering “limp mode” and unable to exceed 3,000 RPM or 50 MPH. The first failure occurred 9/14/25 while merging onto the interstate, forcing me to lose power mid-acceleration as surrounding vehicles slammed their brakes to avoid collision. 13 days later, it happened again in stop-and-go traffic, leaving me stranded on the shoulder. Both incidents occurred without warning or prior check-engine lights. The third—and most terrifying—incident was on October 17, 2025, when the engine completely died 300 miles from home on a busy highway. My children, ages 4 and 6, were terrified as cars sped by. We were extremely fortunate not to have been hit. I am urgently requesting assistance for the immediate replacement of this vehicle’s engine. It is covered by Hyundai’s 15-year/150,000-mile extended warranty, clear evidence the company was aware of these issues. Service records from the previous owner-that I was told about by Hyundai show ongoing engine problems and recalls since 2022 further proof this vehicle should have been retired from service As a parent, I’m very alarmed that Hyundai refuses to act until “catastrophic damage” occurs. This policy is irresponsible and endangers entire families. There’s at least 50 NHTSA complaints describing identical issues; stalling, power loss, and bearing failure linked to defective connecting rod bearings. Yet, Hyundai has denied a replacement, insisting on waiting for further damage and failures in operation. I beg you to intervene and prioritize my family’s safety before tragedy inevitably strikes. My children should not be put at risk due to corporate negligence, greed and absence of accountability.

On [XXX], the vehicle was involved in a complex multi-impact accident. It was struck by a vehicle on the passenger (right) side and, simultaneously, by another vehicle on the driver's (left) side. (Police Report). During this sequence of collisions, and despite the magnitude of the impact, I must express my extreme concern that the left side airbag (driver's side) did not deploy. This failure caused Mr. [XXX] , the undersigned, to suffer a neck injury as a direct consequence of the incident. Even more seriously, the right-side passenger, Ms. [XXX] , sufferedsevere internal injuries, including three small intestine perforations, according to medical reports. These injuries resulted from improper pressure or malfunction of the seatbelt for that seat. These combined failures, the non-deployment of an essential airbag in impact, and the serious internal injuries caused by the seatbelt represent unacceptable deficiencies in the vehicle's safety systems. We believe that these injuries could have been avoided or mitigated if the safety components had functioned properly, as expected in an accident situation of this magnitude. Therefore, I am at a loss to understand: 1. Why the left side airbag did not deploy during the impact. 2. Why the right passenger seatbelt caused such serious internal injuries, including the three diagnosed intestinal perforations. We also require that concrete and immediate action be taken to address and compensate for the serious injuries suffered by the vehicle's occupants, as this has caused psychological and work- related harm.

The contact owns a 2021 Hyundai Tucson. The contact stated that while driving 35-45 MPH, the vehicle shut off unexpectedly. There was an abnormal rattling sound coming from the vehicle. Additionally, the contact stated that the vehicle failed to accelerate while driving. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed that the rod bearing and the engine needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was taken to another local dealer, Hyundai of Orange Park (7600 Blanding Blvd, Jacksonville, FL 32244); who determined that the coils needed to be replaced. The vehicle was not repaired. The vehicle was taken to an independent mechanic who replaced the coils and determined the failure was due to the engine. The vehicle was repaired, but the failure reoccurred. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 124,500.

Power TrainMay 2025 · ODI 11660001Details +

When sitting at a stop and then accelerating to leave the stop position, the car will go and then all of a sudden it will stall out and I'm pressing the gas pedal, pressing the gas pedal quite a few times before the car even decides to move. This happens when I'm changing lanes on the highway... merging onto the highway... when I'm leaving from a stop sign or a stoplight it happens continuously. It is very dangerous and it can cause a very bad accident....this has been an issue since I had bought the car 3 years ago...it seems to be happening more frequent

Electrical SystemApr 2025 · ODI 11656391Details +

The AC system on my vehicle stopped working with less than 55,000 miles on it. When replacing the compressor, condenser, all AC switches, and lines (the entire AC system besides the ECM), the AC is still not working. The compressor is not kicking on. I have an ECM on order, but myself, and all mechanics (including Hyundai certified mechanics) are all unsure why this would have happened on such a low mileage vehicle. I am EXTREMELY disappointed and frustrated with the experience and not having AC after spending thousands of dollars and time getting it fixed. Please advise ASAP. Attached is the original invoice stating that all that needed to be replaced was the condenser/compressor. I have more files from all of the other replacements provided if needed.

Around November 1, 2024 my 2021 Tucson check engine light came on. I had this checked out and was told by a mechanic that it was the Camshaft Sensor. I had this repaired and then on November 23rd while traveling to Ohio my Check Engine light started flashing and needed immediate attention. I was on the West Virginia Turnpike when this happened and it caused the car to go no more that 45 mph in a zone marked 65mph. We got this immediately checked out and repaired and then 4 days later the same thing happened while in Ohio. It was taken to Deihl Hyundai in Massillon, Ohio and they once again made this repair with video evidence of said repairs. Once again while driving at freeway speed on December 23rd my car experienced this malfunction. The same dealership fixed it once again with direction from Hyundai. I am concerned for this is an ongoing problem and could cause serious injury to myself or others in my vehicle if this would happen once again on a freeway.

My check engine light came on in the vehicle and immediately the acceleration declined and I wasn’t able to go above 50 mph. I brought the vehicle to the dealership to which the code 1326 came up. I was told it is a rod bearing engine failure and I need a new engine for the vehicle. I was also told my vehicle doesn’t qualify for the recall already made for this damage and code number.

SteeringApr 2024 · ODI 11585434Details +

What component or system failed or malfunctioned, and is it available for inspection upon request? Steering column. How was your safety or the safety of others put at risk? Steering column would not disengage and remained locked up after the vehicle was started and in gear. This have caused me to almost get into a few collisions for the same issue. I have had friends and family, most recently my daughter, in the vehicle when these issues have occurred. I have almost collided with walls, cars, etc due to this issue. Has the problem been reproduced or confirmed by a dealer or independent service center? No. Despite the numerous videos I have presented documenting these incidents, they state they have been unable to reproduce. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Manufacture has not inspected the vehicle and keeps sending me to the local dealership where the vehicle was purchased from. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. During the issues where the steering column does not unlock or disengage, it displays a yellow light with a car and key symbol in it. During other issues I have experienced with this vehicle (phantom braking, acceleration / power issues, random dash controls turning on, and the electric e-brake failing to properly disengage, there have been no lots on the dash that were noticeable. Restarting the vehicle tends to rectify the issue.

EngineFeb 2024 · ODI 11574644Details +

I was contacted by Hyundai last year about a possible recall on my engine so I brought it in October 2023 to have it checked out. I was told that everything with the car was fine. Fast forward to last week 02-21-2024 and my engine starts shutting off while driving ON THE HIGHWAY? I have it towed to a new dealership in Jacksonville FL Jenkins Hyundai I believe. They inform me that it is indeed the engine and it will be replaced for free under warranty. However, it’s been over a week and the parts for the car are still not available. I have researched online and found I am far from the only one this has happened to. I was not given a loaner car and they did not offer to pay for my rental but I was told they would reimburse me. I was also told that they would just pay every week for a rental car for me but then I was later told that that was a flat out lie. After March 7th when the rental car I have is to be returned I can no longer afford a rental car and will not have access to reliable transportation. This could potentially result in me losing my job. This is unacceptable and Hyundai should be investigated and held accountable for selling cars they know have faulty engines.

Panoramic sunroof spontaneously exploded when driving on highway. No warning. Sounded like a gunshot. Had to pull over on the highway and clean off as much glass as I could so it did not cause injury or damage to other motorists. Looks like many other Tucson owners are experiencing similar issues. Has not been inspected yet as dealerships and insurance are closed today.
