2026 Chevrolet Silverado 1500

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,

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.

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.

My 2026 Chevrolet Silverado 1500, LT Trail Boss, did not include a printed version of the Owner's Manuals and Guides. I have experienced issues with using automatic Car Washes with the truck lurching while inside the Car wash, the online version of the manual is difficult to use at times when internet access is unavailable. My VIN is not listed in the recall N252532020. Another issue is with the Driver's Seat, the retainer for the leather upholstery keeps popping off under the seat that can cause it to become caught in the seat's mechanics.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle came to an abrupt stop in the middle of the road and the vehicle shut off. The contact indicated that the failure had occurred on four separate occasions. The vehicle was taken to the local dealer, who was unable to duplicate the failure or find a fault code associated with the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The contact was also informed that the VIN was not included in NHTSA Campaign Number: 26V289000 (POWER TRAIN).

I just purchased this vehicle on XXX and on XXX, with less than 300 miles on it, we were in a parking garage at the Galleria Mall in [XXX]. While driving slowly uphill in the garage looking for a parking space, the vehicle suddenly went into neutral and the engine shutoff. After verifying all was well, I restarted the truck and continued to drive. It happened two more times with the same situation, low speed going uphill. I have not taken it to a Chevy dealer yet for diagnostic as there were no lights like the check engine light and no codes presented. My onstar app reports that all is well and no issues, so I know it will not be something they can find when they try to pull the codes. I did a search on the internet for this issue and found others with the same problem, no known fix, and in one case the person was able to return the truck and they purchased a different truck from a different manufacturer. That gentleman said he did try to work with GM at the regional level with a service rep. He said something is causing the voltage to drop in lower gears, causing it to invoke a safety feature to stop the vehicle by going into neutral and shutting off the engine. On an incline, with no engine, the brakes become very hard to push and the vehicle could roll back. In a parking garage, that could mean rolling back into a person or another car. When it happens there are in internal codes that do not show up, but are wiped when you re-start. There are threads on Reddit and in Facebook groups that discuss this issue as well for further evidence. My purpose is to get this documented outside of GM, it seems like a niche problem, but one that could be dangerous in the right circumstances.

I have been having issues with my vehicle for the last 1,000 miles or so where it appears to be losing power while accelerating normally, i'm not sure if the issue lies with the engine or powertrain/transmission. I took to dealer last week and they were unable to reproduce. The issues have been getting more frequent and intially were only occuring after the vehicle warmed up, now it has started while vehicle is cold. Feels like the power drops (rpms drop) during a normal acceleration. As of 7/16 I now have a check engine light on, onstar indicates an issue with my engine, transmission, electrical. This is putting myself at safety risk along with others as during my normal drive the engine is losing power and could either leave me stranded or cause an accident.

On XXX I was driving from [XXX] to my sister's house in [XXX]. I was relocating to [XXX] for a job. I was pulling a U-haul trailer (6x12) that contained significantly less weight than the truck can handle. About halfway there, on back roads, the truck suddenly slowed significantly and the gas pedal was unresponsive. The light in the dashboard read Reduced Acceleration - Drive with caution. Pulled over, turned off truck, opened driver side door, to reset the truck (read this on google). We had to do this a couple times, because it would just go back to that behavior after a bit. We made it to my sister's house to stay the night. In the morning, XXX, I called the local Chevy Service Dept in [XXX] and asked if I could bring it in, I described the problem. During the drive to the shop, the same issue occurred. Upon arriving at the service dept, the Trailer app was giving a warning that the load may be heavier than max. Which cannot be true. The dealer techs said they had never seen anything like it before, but they seemed to know what to look for. They then informed me that they could not loan me a car because I was traveling out of state. I had a deadline, so my only option was to rent a U Haul box truck, unload the back of my truck into it, hitch the trailer I already had to it, and drive to [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
