2026 Chevrolet Silverado 1500

While driving this 2026 Chevy Silverado, the engine has shut off while driving it. While driving down the road the engine will shut off and a message on the display will show "Return to Neutral" and "Press Start". This is very dangerous to have a vehicle shut off while driving down the road as it affect my family and other drivers on the road. The vehicle need to be completely stopped to shift to Park, in order to start the vehicle again. There are no signs or warnings that this is going to happen, it just happens randomly. The dealer can not reproduce the problem but did confirm to me this has happened to several other same make/model vehicle that have been reported at the same dealership. On another unrelated safety issue with this same vehicle, the gas tank over flows when filling it up. Dealer was able to reproduce this problem, but doesn't know how to fix it yet. Is waiting to GM to approve what should be replaced, under warranty. This is dangerous for me and other people at gas stations. I can't fill my vehicle up all the way with fuel, otherwise it runs down the side of the vehicle and on to the ground where it is very flammable.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving 70 MPH, the vehicle burst into flames. When the Police and emergency services arrived, the vehicle was fully engulfed in flames. The contact stated that an oil change was performed prior to the failure. The fire department extinguished the fire. A Police report was filed. The contact associated the failure with GM Service Update: N262568830 (Potential Oil Filter Leak). The customer service assistance at the manufacturer was notified of the failure and opened a case. The failure mileage was approximately 11,000.

I am submitting this formal statement regarding a severe, recurring safety hazard involving sudden engine stalling and internal mechanical noise on my 2026 Chevrolet Silverado 1500.The vehicle has experienced multiple sudden engine stalls during low-speed deceleration, specifically while letting off the accelerator pedal to execute low-speed turns into parking lots. When the stall occurs, the engine dies completely, causing an immediate and dangerous loss of power steering and power braking assistance mid-turn. Because the vehicle shuts off completely while still in motion, I am forced to bring the truck to a dead stop, shift the transmission out of Drive and into Park, and completely cycle the ignition system to restart the engine.There is a distinct, audible mechanical ticking sound coming from the engine compartment during operation. Crucially, the vehicle has never illuminated a Check Engine Light, displayed a dashboard warning message, or given any advance electronic indication prior to or during these sudden stalling events.This vehicle's build window falls directly into the scope of the National Highway Traffic Safety Administration’s (NHTSA) active Engineering Analysis (EA26005) investigating catastrophic valvetrain and engine failures on GM 6.2L L87 engines. Because this defect causes an unexpected loss of vehicle control with zero diagnostic warnings, it poses an immediate highway safety risk to myself and others.I request a full diagnostic scan for hidden or pending fault codes, a physical inspection of the valvetrain/Dynamic Fuel Management (DFM) system, and an inspection of the engine oil filter for metallic debris indicative of internal bearing degradation.

My 2026 Chevrolet Silverado experienced catastrophic engine failure at approximately 12,000 miles. The vehicle was out of service from June 19, 2026 through August 27, 2026 while the engine was replaced. This is our family vehicle and is regularly used to transport my two young children. I remain concerned about the safety and adequacy of the remedy following such an early catastrophic engine failure. I requested that GM repurchase the vehicle or provide trade assistance so that I could move my family into another vehicle; both requests were denied. I am submitting this complaint so NHTSA has a record of the failure and my concerns regarding the remedy provided.

2026 6.2L engine loud and oil filter is filled with bearing glitter. I know you have recently opened an investigation into 2025 and 2026 GM 6.2L engines also failing. The salesman lied and told me the issues were all fixed. How is a company allowed to lie and put my family at risk with a faulty engine. I am driving and engine that is shedding bearing material for 3 oil changes. This will fail and leave me stranded or create an accident. 1st oil change at 1500, second at 6000, 3rd at 10,500 and oil is full of bearing material. Pics attached

In Late December 2025, with only 764 miles on my 2026 Chev truck, we were driving south on [XXX] down the interstate in Utah. The engine lost power, service enging light soon came on, and the truck came to a stop in about a mile. There were 5 of us in the truck. Late night, in a strange town. We had to take a UBER to the motel. The truck was towed to Murdock Chevrolet in Woods Cross, Ut. They gave us a lowner car, and they took the engine out, and sent it to GM. GM took the engine apart, and said verably that a crankshaft bearing went bad, and they sent a new one. Within 30 days, I had my truck back. I asked for paperwork on the repairs, and was told GM would not give me anything. All I got was my truck. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving down a main road going 40-45 mph. I made a left turn into a retail shopping center, went straight for about 100 feet and turned right into the main shopping center street and the truck immediately just shut off. I don’t remember seeing the car go into park, but I do remember it going into more of a neutral state with the engine completely off and the brakes were not locked since the car rolled back a little bit at first. My wife and I were both in awe as to what just happened. Thankfully, we were not on the main road and were able to turn the car back on and it seemed to be fine after that and shifted into drive with no issues. It hasn’t happened since. The car probably had approximately 2000 miles on it at the time.

I purchased the 2026 Chevrolet Silverado with a 6.2L motor "new" from the dealer with 5700 miles on XXX. Roughly a month and 2500 miles later, my family and I were in the vehicle, 750 miles from home, returning from a vacation to [XXX] from the [XXX]/[XXX] area. It was around 8:30 in the morning and we had been on the road since the 6 o'clock hour. We were towing our our 20' fishing boat at the time. We were in the left most lane, passing a semi tractor trailer. I signaled and moved back in the 3rd lane after the pass. We were now the vehicle in front of the semi. At this moment, the engine locked up. The torque converter which had been locked at highway speed came unlocked. The transmission started aggressively downshifting looking for torque, RPMs racing upwards of 6k. We were now on an uphill, towing, with a seized engine in front of a semi. In the next lane right was a family in a newer lincoln navigator going freeway speeds. Aside from the transmission, the engine was silent, the accelerator did nothing. A message pops on the screen. "Shift into Neutral" is says... a fraction of a second later "Restart Engine" or alike. The start button was unresponsive. We're losing speed, the sem i is right on the back of the boat now, the [XXX] navigator was even in the lane with the semi. This is where split second decision making mattered. I glanced to the right most lane, empty. All I could do to get off the interstate was to yank the wheel to the right and at what felt like a 45 degree angle, rip across the three lanes to the only shoulder available. The navigator was obviously caught off guard, as they had been slowly gaining on/passing the semi at the time. The navigator locked up it's brakes, skidding out of control before regaining it. Now it's still. Engine off. Only the noise of the freeway and the navigator driver, still honking profusely and deservedly. My heart was just pounding. Breathe. You're all alive. Thank God.
