2026 Chevrolet Silverado 1500 ICE

Multiple instances of engine shutting off while driving and switches to "Park". Most recently the truck suddenly lost power, shut off, stopped immediately, went into Park, jerked extremely hard, and displayed the message “Service Transmission.”

Incident Aug 28, 2026

Driving on the interstate and the truck had a horrible vibration. It smoothed out and it did it again. I got off at the next exit and the engine was making a horrible knocking noise. I had it towed to my Chevy dealer for inspection. They drained the oil and found excessive metal in the oil. They decided that the engine needs to be replaced. The truck only has 4524 miles on it and it was purchased in June of 2026.

Incident Nov 18, 2025

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving 10 MPH, the message “Push Start and Shift to Neutral to Continue Driving” was displayed. The dealer was contacted by phone and made aware of the failure. The vehicle was taken to the dealer; however, the failure was not duplicated. The failure mileage was approximately 11,000.

Incident Aug 25, 2026

The contact owns a 2026 Chevrolet Silverado 1500. While driving at an undisclosed speed, several brake warning lights illuminated on the instrument panel. The contact attempted to depress the brake pedal, and the brakes failed to respond as needed. The contact pumped the brake pedal continuously to bring the vehicle to a stop. The vehicle was then driven in LIMP Mode. The vehicle was taken to a dealer and was diagnosed with a brake control module failure, which was caused by an incorrect software version that had crashed the module. The manufacturer was notified of the failure. The failure mileage was 4,300.

Incident Sep 9, 2026

Engine seized and stalled while vehicle was in motion. This resulted in failure of power steering assist and power braking assist. This made vehicle extremely difficult to maneuver safely out of the flow of traffic. The engine seizure was confirmed by a Chevrolet dealership. And the engine was replaced by the Chevrolet dealership. There were no warning lamps. The engine made some unusual noises moments before failure.

Incident Aug 9, 2026

Picked up truck at the dealership with a friend and stopped at Restaurant across from the dealership. I backed into a parking spot and shifted into Park and pressed Button to shutdown Engine. No audible warnings were given to indicate that I did something improperly. We exited the vehicle and the only sound heard after I closed the door was the audible alarm that reminded me that the spare key was inside the vehicle. We walked approximately 30 to 40 feet and heard a crack from a limb that the truck struck as it rolled backwards down a small hill and crashed into a building. No one was hurt. Upon checking the vehicle, we noticed that the shifter indicated that it was in Reverse after impact. Onstar was notified because of the crash and we relayed to it that no one was hurt. Truck taken to Body Shop.

Incident Sep 4, 2026

While driving in a parking lot. Barely applying throttle to move straight forward not turning or driving on a rough road the truck completely shut off all screens went blank and I wasn't able to accelerate. I was able to restart the truck, shift into drive and continue but took a few seconds to realize the issue and properly restart the engine. Thankfully this occurred while in a parking lot without anyone behind me but this is a real concern for me now driving on streets/highways with other vehicles around. This truck was purchased brand new has never been off road and has just over 3,100 miles. There were no warning lights before or after this incident.

Incident Sep 17, 2026

No warning lamps or chimes. Truck shut down as I was pulling into my garage. Shifted to neutral on its own and a message on the dash said to put it in park and restart the engine. This event happened on 9/15/26. The truck has 1400 miles on the odometer.

Incident Sep 15, 2026

2026 chevy Silverado 1500 Lt Trail boss only has 2300 miles on it about 2 weeks ago pulling in to the driveway the truck shifted into neutral and died and prompted me to restart. started find a few days later it did the same things. The truck has shifted into neutral and died pulling up to a light at slow speeds 4 or 5 times. It has done this twice at highway speeds on overpass incline. On 9/13 the truck shifted in to park while drive 5mph in at parking lot and shifted in to park on its and died will driving.

Incident Sep 13, 2026

While driving at about 20mph we hear a grinding noise and the truck throws itself into nuetral and then shut off. The truck seems to be on like when started with the key fob, on but not fully started. A warning message comes on the dash stating "conditions not safe to drive". The truck would not go back into gear, even after pressing the start button and truck regaining power. Pressed on the brakes to stop, put in park and then back into drive. Message warning went off and truck drove as normal again. This has happened twice since purchasing the vehicle in May 2026.

Incident Sep 17, 2026

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.

Incident Sep 1, 2026

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,

Incident Feb 10, 2026

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.

Incident Sep 12, 2026

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.

Incident Aug 15, 2026

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

Incident Sep 6, 2026

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.

Incident Aug 30, 2026

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.

Incident Jun 19, 2026

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.

Incident Aug 29, 2026

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

Incident Sep 2, 2026

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.

Incident Jun 1, 2026

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)

Incident Dec 22, 2025

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.

Hood scoop blinds me (and passengers) when sun reflects off it. Who designed this????!!!!

Incident Apr 15, 2026

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.

The vehicle was taken to a dealer to be diagnosed; however, the cause of the failure could not be determined. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 300.

Incident Aug 27, 2026

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 called on behalf of a leased 2026 Chevrolet Silverado 1500 company vehicle. The contact stated that on multiple occasions, upon depressing the brake pedal, the vehicle failed to respond as intended or required significant force to come to a complete stop. No warning lights illuminated. The local dealer was not contacted due to company policy, and the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 71,413.

Incident Apr 1, 2026

I purchased this vehicle brand new and have experienced a recurring issue when coming to a stop. The forward sensors activate indicating I am too close to an object (even though nothing is in front of the vehicle), and the engine stalls. Everything shuts off except the driver information screen, which displays the prompt "Shift to Neutral and Press Start Again." Following this prompt does nothing; I have to shift into park and press the ignition again to restart the vehicle. I have taken the truck to the dealership multiple times. After the first two visits yielded no solution, the maintenance team contacted Chevy engineering, and a hard reset was performed. However, today (8/24), a similar issue occurred. While at a complete stop with a full car length between my truck and the vehicle ahead, the sensor warnings activated. The engine did not stall as it had before, but the issue seemed entirely random.

Incident Aug 24, 2026

On or about XXX the engine in my 2026 Chevrolet Silverado quit running so I had it towed to Daniels Long Chevrolet in [XXX] where I had purchased it new on or about XXX. My truck was bought with the 6.2 L V8 engine, and it had approximately 8,627 miles on it when the engine had quit running on XXX. The first oil change on the truck was performed at approximately 5,000 miles at Daniels Long Chevrolet with the prescribed oil. There was no warning when the engine quit running other than the engine running rough and having a loss of power about two blocks from my house. I then had the truck towed to Daniels Long Chevrolet for repairs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 900.

Incident May 26, 2026

After grocery shopping, I was putting items into the back seat on the floor of the truck. I lifted the seats to allow for more room. I went to push an item to the far side of the truck to allow for more room. During this action, I put my left hand down with my knuckles facing the floor to provide leverage. without realizing where I was putting my hand, I placed the middle segment of my ring finger directly on the edge of the mechanical-jack and put my weight onto it. The jack is not covered and is black (the same color as the carpet). The edge of the jack has sharp burrs. As a result, I was cut across the entire middle segment of my ring finger and slightly on the knuckle of my middle finger.

Incident Aug 16, 2026

I was making a sharp turn going about 6 miles an hour. The vehicle suddenly stalled and shifted to neutral. A message appeared on the dash stating, “Please restart vehicle.” The vehicle restarted without issue and no error codes were displayed.

Incident Aug 9, 2026

Tailgate keeps randomly opening when driving down the road. Vehicle was taken to a Chevrolet dealership for them to address. GM denied warranty claim and will not provide anything in writing. This is a huge safety concern for a work truck that hauls tools and equipment on a daily basis. And the fact that GM will not give anything in writing on the denial is absolute BS.

Incident Jul 17, 2026

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving approximately 30-40 MPH, the liftgate opened unexpectedly. The contact pulled over to the right side of the road, exited the vehicle, and closed the liftgate; however, the failure persisted. There was no warning light illuminated. A dealer was contacted. The vehicle was taken to a dealer to be diagnosed; however, the diagnostic result was unknown. The vehicle was not repaired. The approximate failure mileage was 5,070.

Incident Jul 17, 2026

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.
