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

POWER TRAIN,VEHICLE SPEED CONTROL — Filed 06/17/2026

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.

Engine stopped while driving. Truck made dinging noise. Dash had no warning lights. Dash said need to press start button to turn on. Truck went into neutral by itself. Was able to pull over and put it in park. Tried to push the start button and nothing. Dealership said it needs a new motor. The truck has less than 10k miles. The motor has already been replaced once before at 4070 miles.

EXTERIOR LIGHTING — Filed 07/02/2026

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.

POWER TRAIN,UNKNOWN OR OTHER — Filed 06/09/2026

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.

ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM — Filed 06/30/2026

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.

A call to GM has been made waiting on a response. Gm case#XXX. Truck is 2023 with 62k miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

STEERING,ELECTRICAL SYSTEM,ENGINE — Filed 02/27/2026

On [XXX], my 2023 Chevrolet Silverado 1500 LT caught fire while parked in my residential driveway at [XXX] . The vehicle had been started approximately 10 minutes earlier using the factory-installed remote start system. The vehicle was unattended at the time. My neighbor noticed the vehicle on fire and called 911. The Andover Fire Department responded and extinguished the fire. The fire department indicated the fire appeared to be electrical in nature. The fire appeared to originate in the dashboard and steering column area based on visible damage and fire progression. The vehicle had approximately 60,000 miles and was properly maintained. There were no prior warning lights, messages, or symptoms before the fire. The remote start system was factory-installed and not aftermarket. The vehicle is currently available for inspection by insurance, manufacturer, or investigators at [XXX] . The vehicle is likely a total loss due to the extent of the fire damage. This incident posed a serious safety risk as the vehicle caught fire spontaneously while parked near my home. The fire could have spread to my residence or caused injury if someone had been inside or near the vehicle. The fire department responded, and an official fire report is pending. Insurance claim has been opened and inspection is pending. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FORWARD COLLISION AVOIDANCE — Filed 07/20/2024

This weekend while traveling on I95N I got into a wreck with automatic cruise control on. I had been in stop and go traffic for about 20 minutes and was following behind a Gatormade hauling trailer for well over a mile with no issues. Suddenly, from a dead stop, the truck attempted to accelerate to its preset speed of 50 mph. I was only one car length away from the trailer and wasn't covering the break. By the time I got my foot on the break, I slammed in the back of the trailer. At no point did the emergency brake warning or any alerts pop up.

FORWARD COLLISION AVOIDANCE — Filed 08/15/2023

I was driving Eastbound on highway 150 on my way to work. I have adaptive cruise control in my truck and have used it many times before on this exact road with no issues. Traffic was moving slow and the adaptive cruise control was following the car in front of me exactly how it is designed to do (ACC can be turned on at speeds as low as 5 mph in this vehicle and can come to a complete stop and restart movement from a complete stop). I drove through a section of this road right after the lake crossing where the morning sun was pretty bright directly facing us for a few seconds. During this time my foot was off of the accelerator and brake as instructed by the vehicle manual for safe operation of the ACC system. In these few seconds the truck unexpectedly accelerated aggressively with no warning and before I had a chance to react the truck rear ended another vehicle, pushing it into the car in front of them as well. I have been found liable so far by insurance. I am trying to argue on my behalf. I firmly believe I am not personally liable for this accident. The system in the truck is supposed to fail safe (meaning when meeting uncertain variables, such as low camera visibility, the vehicle should disengage the ACC instead of aggressively accelerating with no information of what is in front of it) and it did not in this circumstance. As stated, I had no input to the accelerator or the brake at the time of the accident according to the owners manual safe operation of this system. The vehicle FAILED to disengage the ACC system as it was supposed to and caused an accident I had NO TIME to react to by aggressively accelerating without any warning. The vehicle has been appraised for repair by the insurance company and was found to have $7000 in damages.
