THIS NEW TRUCK HAS BEEN IN 2 DIFFERENT DEALERS FOR THE SAME TRANSMISSION ISSUE, 2 TIMES WITH CHAMPION CHEVY AND 1 TIME WITH MICHAEL HOLH CHEVY/GMC DEALER, FIRST 2 TIMES NOT ABLE TO DUPLICATE THE ISSUE AT CHAMPION CHEVY, 3RD TIME I WAS ABLE TO DUPLICATE THE TRANSMISSION ISSUE NOT ALWAYS DOWN SHIFTING INTO FIRST GEAR WHEN STOPPED OR ON A HILL, THERE SHOP FORMAN STATED THATS NOT RIGHT, BUT YET THEY DID NOTHING TO TRY AND RESOLVE THIS ISSUE, I FILED A COMPLAINT WITH CHEVY CORPERATE OFFICES AND AGAIN NOTHING WAS DONE TO RESOLVE THIS ISSUE. LEMON LAW WILL NOT TAKE EFFECT UNLESS THEY FIX SOMETHING SO IN MY OPINION IF YOU DONT FIX IT THEN THE CONSUMER HAS NO RECOURSE, PER LEMON LAW LAWYER,

FUEL/PROPULSION SYSTEM

The engine cut itself off and shifted itself into neutral as I was slowing down and turning left into the gas station. It is available for inspection. My safety was at risk because had this happened on a legal road way, it could’ve caused someone to rear end me or t-bone me because I would’ve unexpectedly stopped, or the power steering may not have worked and I could’ve run into something. It has not been reproduced by any mechanic, only me. It has happened to me only twice within a 400 mile span. It has been inspected by a GM dealership twice now and is currently still at the dealership. There were no warnings of any kind before, during, or after the occurrence.

TIRES

the General Grabber HTS 255/70 R17 off a 2026 Chevy 1500 truck from factory with only 17k miles, has had multiple leaks from what appear to be the rubber itself cracking and no objects seem to be making the punctures. (this tire itself the main reason for this report has been repaired 4 times and now has its 5th leak) but at least 1 or more repairs have been made for 3 of the 4 tires as well as another chevy truck same year, model and tire from factory but only 1 of their tires has failed as of today. One of the tire punctures has leaked 5 psi within 1 mile distance. For obvious reasons of a tire going flat and so fast for no reason this can be extremely dangerous for the occupants of the vehicle as well as others that are on the same roadway,( locations to pull over, weather conditions IE icy roads and pos tire ruptures) The conditions have only been observed in the late spring, summer, and fall, they have not yet been seen in the winter, but is expected to fail more often as the cold with cause the tire to become more brittle and prone to more cracking. The Chevy truck TPMS does provided a fast and accurate tire pressure give the driver enough time to make decision on the best location to stop

ELECTRICAL SYSTEM

Twice under 3200 miles while pulling into driveway on an incline the vehicle shifted to neutral then turned off and began to roll backwards down my driveway. No codes or CEL came on the display read press start to restart engine so I did that and it started and ran normally until it happened again while pulling into driveway. I took vehicle to my local chevy dealer they pulled history codes and saw 8 communication error codes with various areas of vehicle, checked battery and charging, test drove it and said they found nothing wrong with vehicle. This is a safety issue and should be investigated further, very disappointing on a brand new vehicle only 3 months old.

POWER TRAIN

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.

ENGINE

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

ENGINE

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.

ENGINE

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)

POWER TRAIN

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.

VEHICLE SPEED CONTROL

On XXX, my Chevrolet Silverado experienced a sudden, severe loss of normal braking shortly after I dropped my child off at school. When I attempted to stop at a stop sign, the vehicle would not stop normally. The brake pedal remained firm, but braking effectiveness was drastically reduced and required extreme force. The dashboard simultaneously displayed multiple warnings involving the brake/ABS system, ESC, steering-column lock, and trailer-brake system. OnStar generated a diagnostic/safety report identifying fault/error code P062F. The vehicle then entered a reduced-speed/limp-mode condition. I was extremely fortunate this occurred within approximately one mile of Rick Hendrick Chevrolet of [XXX] and with little traffic around me. I was able to reach the dealership without a collision. Had this occurred at highway speed, the inability to stop normally could have resulted in a fatal crash. The incident also occurred immediately after school drop-off. Had I used the normal car line instead of parking and walking my child inside, this failure could have occurred among stopped vehicles while children were actively exiting them. I immediately brought the vehicle to Rick Hendrick Chevrolet. Despite the seriousness of the event, I do not believe the cause was adequately investigated. To my knowledge, a computer/software update was performed and I was essentially told to “let them know if it happens again.” They also asked what i was towing - nothing.I questioned whether an electrical fault or short could have caused the multiple simultaneous failures, but I am not aware of that possibility being investigated. Because another occurrence could cause serious injury or death, I refused to continue driving the vehicle and traded it in. I have now learned that the same vehicle is being offered for sale again. I am reporting this to NHTSA because I am concerned the underlying safety defect remains unresolved and could represent an early instance of a broader defect.
