The left front turn signal becomes inoperable at times. The foreword collision indicator warning will come on unprovoked at times. Both conditions correct when you cycle the ignition switch. I consider the turn signal problem a safety issue because it happens with no warning and oncoming traffic may not know I am turning left or changing lanes. When the foreword indicator appears, I doubt the system is operable.

On June 27th 2026 at approximately 3am, I was driving my Chevy Silverado Trail Boss with 6.2 engine, it suffered a sudden catastrophic failure and it completely seized while in motion. There were no warning or signs given while vehicle was in motion. This resulted in an immediate highly dangerous loss of propulsion on a dark 2 lane road. The vehicle would not crank and had to be towed to Estero Bay Chevrolet.

On Sunday, July 12, 2026, the 6.2L V8 (L87) engine in my 2023 Chevrolet Silverado 1500 ZR2 seized and locked up completely, resulting in total loss of propulsion. I was driving at 65 MPH when it felt like the transmission was slipping and I lost power and coasted the truck to the side of the road. COMPONENT: Engine (6.2L V8, RPO L87) — connecting rod/crankshaft failure consistent with Safety Recall N252494001 (NHTSA Recall 25V-274). The vehicle is available for inspection. It is currently at Cable Dahmer Chevrolet, where it was towed on July 13, 2026, and remains inoperable. SAFETY RISK: The engine seized during operation, causing sudden and complete loss of propulsion in traffic. This is the exact failure mode identified in Recall 25V-274 as increasing the risk of a crash. CRITICAL DETAIL: This vehicle previously underwent inspection under Safety Recall N252494001 and PASSED on Feb 3rd 2026 at VAN Chevrolet in Kansas City. GM deemed the engine non-defective and issued extended warranty coverage of 10 years/150,000 miles under the associated special coverage program. Despite passing GM's recall inspection, the engine suffered catastrophic failure. This appears directly relevant to NHTSA's open recall query regarding the effectiveness of GM's recall remedy. DEALER CONFIRMATION: A technician at Cable Dahmer Chevrolet has verbally confirmed the engine is locked up/seized. Formal diagnosis is pending master technician sign-off and submission to GM, expected the week of July 20, 2026. The manufacturer has not yet inspected the vehicle. WARNING SIGNS: No warning lamps, messages, or symptoms appeared prior to the failure. The engine failed without warning

I am filing a formal complaint regarding General Motors' handling of a critical vehicle component that has left my vehicle and many others in an unsafe condition. For more than over a one month, I have been waiting for a replacement gear shift module that is currently on backorder. During this time, I have learned that numerous General Motors customers are experiencing the same issue and are also waiting for this part to become available. My primary concern is that this appears to be more than an isolated parts shortage. If so many vehicles require replacement of the same safety-related component, General Motors should be evaluating whether this issue warrants a safety recall or, at a minimum, notifying affected customers of the potential risks. The gear shift module is a critical component that affects the safe operation of a vehicle. Allowing customers to continue driving vehicles that may have a defective gear shift module without providing a safety notification or timely repair raises serious concerns regarding public safety. I respectfully request that the NHTSA investigate this matter and encourage General Motors to: Explain the reason for the extended backorder of this critical component. Provide customers with a reasonable timeline for obtaining replacement parts. Determine whether this issue should be addressed through a formal safety recall or customer safety notification. Offer appropriate assistance to customers whose vehicles have been affected by this prolonged delay. Customers should not be expected to operate vehicles that may present a potential safety risk while waiting indefinitely for a critical replacement part.

Upon purchasing a used 2023 Silverado, on the first night of ownership, I found the headlight on the passenger side to be defective. The high beams activated approximately a full second slower than the driver's side. It took me a few days to confirm what I was seeing, where I immediately reached out to help from the Chevy dealership it was purchased from. After back and forth, the dealership refused to fix this saftey item as it was "still operational just not 100%" or something to that affect (not a direct quote). The extended warranty company doesn't typically cover headlight housing. The dealership locally says both headlights need replacement. Chevy Corp is involved, under claim 104164057. I've brought to their attention that I have found several reports of this defect online for similar vehicles and model year. My contention is that, particularly due to being the passenger side, this malfunction could lead to accidents and collisions due to distraction of troubleshooting, and the delay of lighting on the side where animals and night hazards typically come from. I've read online reports of these headlights may take up to 3 seconds between sides to both activate, with one side running slower than the other, and eventual failure where the switching mechanism will get stuck. A Chevy dealer confirmed the defect and recommended replacement of both headlights, at my cost, for approximately $4000. Chevy is still investigating and trying to find a conclusion with the dealership, but I contest that I have malfunctioning saftey equipment that could lead to harm or injury, and at the moment, both dealer and manufacturer have been unwilling to resolve the issue. The failure occurs both in auto-headlight and manual modes.

While shifting my vehicle from Park, a "Service Transmission" warning message appeared on the dashboard. The warning would illuminate and then disappear, but the vehicle continued to shift into the other gears. At the time the issue occurred, my truck had only 47,000 miles. I brought it to Blasius Chevrolet in [XXX] on XXX, for diagnosis. The dealership determined that the Transmission Control Assembly (Part # XXX) had failed and needed to be replaced. I was informed that this repair was not covered under the powertrain warranty because Chevrolet considers the Transmission Control Assembly to be excluded from powertrain coverage, and my basic warranty had already expired. I was quoted more than $900 for parts and labor. Initially, I was told the replacement part would arrive within a few days. Later, the technician stated that other Chevrolet dealerships had the part in stock. However, after contacting those dealerships, he was told they would not release their inventory. Chevrolet then advised that the part was on national backorder, with the earliest estimated availability of XXX. As a result, I have been without my truck for approximately one month, creating a significant hardship. After researching this issue, I found numerous reports from other Chevrolet owners experiencing the same failure involving the Transmission Control Assembly. The apparent frequency of these failures, combined with the nationwide backorder of the part, suggests this may be a widespread defect rather than normal wear and tear. I believe Chevrolet should either: Cover this repair under the powertrain warranty, as it directly affects the operation of the transmission, or Issue a recall or warranty extension if this is determined to be a common defect affecting vehicle safety and reliability. I am submitting this complaint because I am concerned that a failure of the Transmission Control Assembly could impact the safe operation of the vehicle.

A valve on the 3.0L Duramax is allegedly sticking, causing the vehicle to go into limp mode or be inoperable. This is a known issue for GM and they have issued a service bulletin on it. Unfortunately, no dealers want to address the issue and now we are left with a vehicle that if we do not pay to repair, after it being ours for only 5 days, the vehicle will be unusable. This vehicle is under warranty still and this part is needed for operation. I believe this avoidance of a recall is harming customers and creating pay to drive schemes. This needs to be addressed before thousands of customers begin paying for a repair that GM knows is their fault.

I have a complaint about GM and my 2023 Chevrolet Silverado 1500 LTZ regarding the radio / infotainment system failure after attempting a recommended software update, and the resulting degradation of installed safety features. On 08 MAY 2026, my infotainment system indicated a software update was necessary, so I followed the directions to complete the update. When the update was complete, my infotainment screen said there was a failure and to take it to the dealership for repair. The entire infotainement system is inoperative. The soonest appointment I could make was for 18 MAY 2026. On 18 MAY 2026, I took my Silverado into the dealership where I have it serviced to address the failure of my infotainment system. My service advisor informed me that I would need a new radio and that these radios are on a national backorder list. My advisor informed me that they have other customers who are experiencing the same issue and have been waiting for the replacement radio since January 2026. My advisor informs me that there is no estimated time of resolution. This defect inhibits safety features such as; use of OnStar, Google and Apple Maps that provide travel advisory hazards, parking camera views, vehicle systems status. Thank you.

My truck has the L87 motor on recall. i purchased it brand new and paid top dollar for it. I've had issues since I've bought it. All of my maintenance has always been done at the dealership from regular maintenance to purchasing brand new tires. I am very disappointed to have a truck that concerns to drive, i do not take my family out in my truck because i am not confident in its reliability and safety. multiple times i've taken my truck in for service and let them know to complete an oil change, tire rotation and to check an issue with a "tick, clunk and knock" just to be told it was "normal for the 6.2". my normal dealership has blocked off appointments online and you'd have to call to try to set one up. I demanded a diagnostic one time when the truck was acting weird and the tech stated "stop by, i'll squeeze you in" in which i did. however, i wasn't given any documentation since "i didn't have an appointment". After reviewing all of my service records, i come to notice not once time did they mention they did a diagnostic check. Only the recall test shows on one of the service records. I've had 3 different viscosity oils in my motor from the dealer stating GM recommended it. I had to night drop my truck on June 14 as it was making a weird noise from the engine and it felt like it had less power. I waited 2 days and the dealer did not contact to even state they have my truck in service. when i called to ask the status i had to agree to text message communication in which they replied, "at best it will take 2 weeks just to look at it". I asked for a loaner since i need a truck for work and transportation, they replied they do not have any and I will be placed on a list. My truck is still under original powertrain warranty and they cannot even provide a loaner. i feel that they are brushing me off to buy time and here i am making hefty car and insurance payments for a truck i do not have nor a truck that I NEED to provide for my family. GM does not care!

6/12/26 ( 2023 Chevy Silverado - 6.2 liter engine) While driving at approximately 40 MPH on a two lane road, the truck shut off. After multiple attempts, the engine failed to restart. The transmission locked up in park and would not release. This required the truck to be dragged up on the flat bed wrecker instead of rolling freely. Prior to this instance there have been several issues with the electrical system. 1. radio sound shuts off. does not come back on. 2. Head lights stay on for 10 minutes after vehicle is turn off. 3. Tail gate opens on it own. Tail gate doesn't open with fob. 4. door locks fail to operate correctly. 5. When drivers door is opened a beeping sound starts and doesn't stop until door is closed. I have reported these problems to GM & have two case numbers. The dealership reports that the 6.2 replacement engines have had multiple failures.

My 2023 Chevrolet Silverado 1500 experiences an intermittant, uncommanded mechanical drivetrain lockup and severe binding when accelerating from a complete stop. The vehicle rolls fine in a straight line for several feet, but the exact moment the steering wheel is turned slightly (a couple degrees), the drivetrain violently binds up. This creates resistance in the steering and acceleration, as well as a severe physical and audible metallic clunking slam and massive shockwave vibrations felt directly through the steering wheel, floorboards, brake/gas pedals, and driver’s seat. During the last event, the vehicle threw a "Service 4 Wheel Drive" dash message and refused to shift out of "Auto" mode back into 2WD. Because this is a pure mechanical interference/binding issue, it does not consistently throw active electronic trouble codes. A standard OBD2 code scan will show nothing. After turning the vehicle off for several hours and testing again, the problem persisted. After towing the vehicle to a dealership (6/10/2026) it sat for at least 5 days before dealership service looked at it. By this time, the active warning lights cleared. My initial servicing dealership refused to perform physical hardware or fluid diagnostics under my factory warranty, stating they would not look at the vehicle unless I paid $860 out-of-pocket or until the drivetrain "completely grenaded" on the road. Because this uncommanded lockup restricts my ability to steer the vehicle safely from a stop, it presents an immediate crash hazard. At the direction of General Motors Corporate, I am escalating this issue and moving the vehicle to a secondary certified facility (Feldman Chevrolet of Novi) on June 23, 2026, for a formal physical hardware and fluid tear-down inspection.

While traveling on the interstate towing a fifth-wheel camper going 55 mph, a message appeared on the dash instructing me to press the Start button. I pressed the Start button, but the vehicle would not start. When I pressed the Start button the entire instrument cluster and navigation display went out. We were able to safely coast to the breakdown lane, skidding to a stop. We remained in the breakdown lane on a busy highway on a holiday weekend in 90+ degree heat for 7+ hours before being towed to a nearby dealership. When the right type of tow truck arrived (capable of towing the truck and camper off the highway), the driver had to remove the driveshaft before the vehicle could be towed to the nearby dealership. This is because of the electronic shift. If the vehicle is not running it cannot be shifted out of park without a special tool. We felt very unsafe sitting in the breakdown lane with cars whizzing by shaking our camper and vehicle at each vehicle passing. Not 1 time did the police stop to provide assistance/make sure all were ok, etc. The vehicle has since been towed to the local dealership and after they inspected the vehicle it was determined the engine seized due to debris in the engine. A replacement engine is on backorder. The engine had already been inspected for the recall and GM 6.2L L87 "fix" was performed, but this did not stop the engine from seizing.

At approximately 24,000 miles the engine had catastrophic failure under normal street/highway driving conditions. The engine is the 6.2L V8. The issue began with a high pitch squeal or chirping sound and noticeable power loss. I parked the truck over night and then drove it to the dealer first thing the next morning. While on the way to the dealership, which was less than 20 miles away, the engine began having much bigger issues. A loud knocking noise was apparent and the rear end began locking up causing the tires to also lock up. Once at the dealership the engine completely failed and locked up. The engine did have the newly recommended 0W-40 oil installed prior to the failure.

I was travelling on the highway at approximately 72 miles an hour in the left lane trying to pass a vehicle in the right lane. while accelerating my truck was like the brakes were slammed on and all kinds of lights starting flashing. This included the check engine light, low oil pressure light and lane assist lights. The truck shifted into Neutral and I could not place back into drive. I swerved and almost lost control of the vehicle and nearly missed colliding with the safety rails on the left of the road and then with the car on the right side. I then pulled onto the shoulder after nearly being rear ended by another vehicle approaching on the left. The vehicle would not react to the gas pedal. I pulled onto the shoulder and turned the vehicle off. Tried to restart but again nothing but mutliple lights and warnings. I checked my app for Chevrolet and it stated that the vehicle needed engine and transmission system service. Variable valve timing system needs serviced. Ingition system needed serviced. The onstar diagnostic alert indicated P0016 was detected. I opened the hood to inspect and the coolant overflow was spewing coolant. I checked the oil level at that point and it was just a little below full. I had taken this vehicle into the dealership two other times stating that the vehicle had stalled before on the highway but not to this degree. The other two times it stalled when accelerating it would allow me to pull over and restart. But both of those times I never had any flashing lights or diagnostic codes. I explained this to the dealership and how unsafe it was. Both of those times almost ended in a vehicle accident with other vehicles around me. The dealership said they could not diagnose any issues unless the truck created a diagnostic code. These issues have been ongoing with these vehicles for a long time and the dealership just did not want to deal with them. I had the vehicle go thru the recall diagnostic tests. It did not fix them

This is a 2023 General Motors 6.2L (L87) engine that was inspected at the dealership where it was originally purchased for the previously issued NHTSA "loss of propulsion" recall and passed without any noted issues. This engine only has ~20,000 miles on it. The engine failed in relatively heavy traffic and could have easily resulted in a serious accident due to inability to route my vehicle to a safe area while under power. This all happened without any prior warning, no check engine lights, noises or lamps or symptoms. The dash simply illuminated with a "Press Start" message.The truck was towed to the dealer for evaluation. The dealer called me today (5/26/2026) stating the engine was seized and a new engine would have to be ordered from GM for installation. This event occurred while the vehicle (2023 Silverado ZR2) is still under the original 36 month/36,000 mile warranty.

Failures include complete loss of camera functionality (rear and front), infotainment system shutdowns or resets while driving, loss of audio, and volume malfunctioning (including sudden increases or no response). The vehicle has also generated false safety alerts, including forward collision warnings and blind spot alerts when no hazard was present. These issues have occurred while the vehicle was in operation, creating safety risks due to loss of visibility systems and unreliable warning alerts. In multiple instances, the system would become completely non-functional for extended periods, sometimes lasting days or weeks, before temporarily returning. The problem has been reported to a dealership multiple times and has been inspected and serviced. Repairs have included software updates and component-related work; however, the issues have continued to persist or reoccur. The failures are intermittent but recurring and have not been permanently resolved despite multiple repair attempts. The condition reduces driver confidence and creates unsafe operating conditions due to unreliable safety systems and loss of critical features while driving.

Transmission has jerked/bumped in past and now at approx 85K miles, it supposedly needs a new transmission. I've heard it is a pretty big issue and seems llike relatively low mileage for this to be happening to 2023 year model. I certainly don't drive it hard and rarely tow or haul heavy loads.

One day the trucks transmission started to struggle to find the next gear after taking off from a light. The next morning it did it again and that night did it a third time. The third time it about brought the truck to a stop at 30 mph and made a bang noise, in which a check engine light came on and a message saying speed limited and drive with caution. The truck only has 20,000 miles and already is having transmission issues, which is just unacceptable.

I am reporting another engine failure on the 6.2L L87. This engine passed the initial recall testing and the oil was changed to 0W40 on September 30, 2025. However, my engine in my 2023 LT Trail Boss started knocking on Friday, March 20, 2026 (at 22,500 miles) after I picked up my children from school. Thankfully it started as I pulled into my driveway with them so they weren’t in any danger. No loss of power on the truck or warning lights visible. However, it was loud enough and odd enough for my [XXX] olds to even notice the sound in the cab. It was dropped off at the dealership on that Saturday morning and the GM dealership was finally able to look at it on Wednesday, March 25th and confirmed what was expected. The advisor stated the engine will need to be replaced due to the engine heading towards bearing/crankshaft failure. I am still currently without my truck as of today (April 4th) with no repair date in sight. I will say that the dealership service advisor has been very good about communicating about its status. However, he stated that he has had no luck finding an new engine and is unable to give a timetable in getting one. He did offer to start a PO for a rental car through enterprise. He stated they are not giving loaners, but could get a rental car. He also stated that it would not be a truck due to GM only giving $50 per day towards a rental. So here I sit currently without my truck. I see multiple reports about the engines being on back order and even the replacement engines are failing within the fist 500 miles. Some reports indicating they are on the third or fourth engine. Something needs to done about getting these trucks bought back by GM. They have clearly failed with this engine and are replacing the failed engines with the same thing! It is a well documented manufacturing flaw and design! I am thankful it occurred near my home. I would not have been happy with a catastrophic failure on a highway with my [XXX] old children in the truck!!

At cold start vehicle often required several seconds for the transmission to engage before moving. After traveling at highway speed (45+ MPH) vehicle began to make clunking noise as if the transmission were changing gears but it was not and the RPMs on the tachometer did not change. Instances became worse and more frequent over 6 month period, vehicle never displayed any codes and no notifications or check engine/transmission lights on driver information center. Took vehicle to O’Fallon Buick GMC and was advised torque converter and transmission valve body had failed and needed replaced. I inquired about ongoing issue with this vehicle based on my findings online and was told it was not a recall issue at this time. Truck has 74,000 miles and service records for all maintenance to date.
