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)

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while stopped at a traffic light, the engine turned off and the instrument panel became inoperable. The vehicle was restarted; however, the failure persisted. The vehicle was taken to the dealer; however, no cause for the failure was found. The contact stated that on a separate occasion, the message "Tailgate Open" was displayed on the instrument panel. The contact pulled over to the side of the road and, upon inspection, noticed that the tailgate was closed. The vehicle was taken to the dealer; however, no cause for the failure was found. An employee at the dealer closed and opened the tailgate several times until the message disappeared. The contact stated that on a separate occasion, the radio stopped functioning, the driver's door unlocked unintendedly, and the driver’s side seat belt failed to retract as intended. The vehicle was taken back to the dealer, where it was diagnosed that the seat belts had failed. The contact seat belts were replaced. Most recently, there was an abnormal sound coming from the engine. In addition, the brake pedal was depressed, and the vehicle failed to respond. After a while, the vehicle was able to stop. The message "BRAKE System Failure” and “Replace Brake Pads and Rotors" was displayed. The vehicle was not diagnosed or repaired. The contact stated that the failure persisted. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The failure mileage was approximately 22,000.

Loss of engine propulsion while traveling down a highway towing a #5000 trailer at 65 mph. Less than five miles before the failure the vehicle experienced a momentary downshift of the transmission such as you would experience while climbing a hill or extreme headwind. No warning lights were present at that time or at any time prior to engine shutdown. Upon failure panel indicated "Press Engine Start" and transmission indicated "Park" though we were rolling/coasting at over 60 mph. Realizing that we had lost propulsion I guided the vehicle to the shoulder and stopped. Solid check engine light on at this time. Depressing the "Start" button while stopped would not start or crank over the engine. Boost box would not crank engine, slight noise from starter as if unable to turn engine over. Called tow truck, Seewald's Towing in St. Ignace, MI. Towed to nearest Chevrolet dealer Wheeler Motors Cheboygan, MI.

My 2023 Chevrolet Silverado 1500 has experienced two separate major drivetrain failures — complete transmission and turbo replacements — within two years of purchase, both during peak use months. The second repair kept the vehicle in service for nine months with no ETA provided until escalation. The repeated failures have rendered the vehicle frequently unusable, caused significant business loss, and represent more than normal wear. Documentation of repairs and dates is attached.

My 2023 Silverado 1500 6.2L ZR2 AEV with 17,500 miles went into the shop for the L87 Loss of Propulsion recall, on 20 OCT 2025. The dealership didnt contact me for 2 weeks, so I called. They than told me my truck failed the pico test and needed a new engine. I also asked for my leaf springs to be looked at under tsb for excessive noise. I also asked for my ZR2 to have the new update installed for the radio fix (my speakers crackle when I talk to people on bluetooth). They had my truck from 20 OCT 2026 until 27 JAN 2026 for a total of 99 days straight. No loaner was available. I had to call GM customer service every week for subpar updates from the dealership. Im active duty army so not having my pov to report to work was very stressful. When I got my truck back, it was covered in dirt, oil on the exterior paint and inside the engine bay. The dealership didnt update my truck as requested and didnt touch my leaf springs at all. They said it would take 5-7 weeks to get new ones, but I needed my vehicle back which is anitated on the work order. Thr parts were all delivered 45 days after it sat there and my truck wasn't worked on until day 94 as advised by the service advisor, as the mechanic would get to it after his next vehicle. I asked how is my truck not priority sitting there for 93 days at the time. GM customer service has submitted my vehicle payment reimbursement as I paid 4 payments while having no vehicle or loaner. $44 a day for a rental at my duty station would cost me considerable amount of my own money to cover the rest and would not be a similar vehicle to my truck, as ot would be a small car. JN Chevrolet in Honolulu did not communicate when it failed the test for 14 days, I had to call them, they gave zero updates for 2 months, I had to call GM customer service. I only received 4 calls in total from the dealership when I asked to speak to the manager. (Who never called me back). I got my truck back filthy, other services ignored. 3rd Silverado and last.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation.
