general problems of the 2026 Chevrolet Silverado 1500 - part 1

Vehicle comes to a stop sign on a low pitch hill. Driver releases the break and presses the gas portal to drive forward and vehicle begins rolling backwards. Driver looks down at the dash and sees a “press start button” message. Driver pressed start button and hears the engine come to life. Driver releases the break and presses the gas pedal to accelerate. Vehicle rolls backwards again. Another message to press start. Driver presses start again. Vehicle is now in park and with the parking break engaged. Driver releases parking break, shifts to drive and is now able to leave the intersection. Issue causes risk of collision due to unexpected rollback. Service appointment schedule for 10/15/26. No warnings presented beyond the start message errors listed above. Newly purchased vehicle: 2026 model year. Appx mileage at time of incident: 122 miles.

On [xxx], at approximately [xxx], I was driving my 2026 Chevrolet Silverado 1500 rst (5. 3l v8, 4wd), leased new on [xxx], with about 122 miles on the odometer. I came to a complete stop at a stop sign on an uphill grade at [xxx]. The auto stop/start feature shut the engine off while I held the brake, as designed. When I released the brake to proceed, the engine did not restart, and the truck rolled backward down the grade. The instrument cluster displayed "press start button. " I pressed the start button, the engine started, and I released the brake again. The truck again rolled backward, and the cluster again displayed "press start button. " at this point, the vehicle was in park and with the parking break engaged. I pressed start a second time. I released the parking brake, shifted into drive, and was finally able to proceed. In total there were 2 failed restarts after an auto stop event, 2 uncommanded rollbacks on an incline, and 1 automatic parking brake engagement. No collision occurred. However, the truck rolled backward toward another vehicle behind it with no engine power, and I had to restart it twice while stopped at an intersection. This is a serious safety hazard in traffic, especially on hills. Gm has published preliminary information bulletin pit5689n, "no restart after an auto stop event / no crank," covering 2020-2026 Silverado 1500 trucks. It cites a loose or broken engine ground strap as a possible cause. This vehicle is 5 days old and the defect appeared within 116 miles of delivery. I am disabling auto stop manually at every startup until the vehicle is repaired. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

After driving for ~45 minutes, while sitting in traffic moving along slowly, my vehicle went into neutral, engine shut off and dash displayed message to press start/stop button to restart engine.

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.

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.

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.

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.

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.

Engine blown at 3,000 miles while going 73 mph.

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.

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.

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.

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. ”.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, all warning lights illuminated and the vehicle stalled. The contact stated that after several seconds, the vehicle was restarted and shifted into park(p). 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.

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.

The first time I was driving in traffic and the truck shut completely off with no warning the display on the dash indicated,please put in park and restart, took a straight to the dealership the code said it was a malfunction with a fuel pump. I had it for two weeks. September 27 it happened again. Took it back to the dealership and they’ve had it ever since.

I am reporting a safety concern involving my 2026 Chevrolet Silverado 1500 high country equipped with the 6. 2l v8 engine. I purchased the vehicle new on August 3, 2026. The engine has unexpectedly shut off on two separate occasions while the vehicle was still moving at low speed. The first incident occurred within approximately the first week of ownership, when the truck had less than approximately 1,000 miles on it. I was slowly driving through the parking lot at mcb’s when the engine unexpectedly shut off while the vehicle was still moving. The instrument panel displayed “press brake to start. ” the engine did not automatically restart, and I had to stop the vehicle and manually restart the engine. The second incident occurred on September 18, 2026, while I was slowly driving through a parking garage. Again, the vehicle was still moving when the engine unexpectedly shut off. The instrument panel displayed the same “press brake to start” message. The engine did not automatically restart, and I again had to manually restart the vehicle. I have a video recording of this incident. This vehicle is equipped with automatic engine stop/start. During normal stop/start operation, “auto stop” is indicated on the instrument panel when the system shuts the engine off. During neither of these two incidents did the instrument panel indicate “auto stop. ” instead, the engine unexpectedly shut off while the vehicle was moving, displayed “press brake to start,” and required a manual restart. Both incidents occurred while maneuvering at low speed in parking areas. I am concerned that the same failure could occur at a higher speed, while entering or crossing traffic, or in another situation where an unexpected loss of engine power could cause a collision. The vehicle has also experienced intermittent electrical/electronic issues, including radio interruptions, remote-start problems, a “key not detected” message, memory-seat/seat-recall problems, and an intermittent power running-.

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).

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.

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.

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 purchased a 2026 Chevrolet 1500 duramax deisel truck. At 9500 miles the truck started making popping and loud grinding noises and would shake while driving it. I barely made it to the dealership on August 6th 2026 I took it to group 1 Chevrolet where I bought it in houston,texas and on August 8th was told that they need to replace the engine and do not have an estimated time for repair.

The engine in my 2026 Chevrolet silverado zr2 with the 6. 2l v8 had a catastrophic failure. While I was driving, the engine suddenly shut off and seized without any warning. The dealer told me they found metal in the engine oil and oil filter and that the engine needs to be replaced. They also informed me the replacement engine is on back order for more than five weeks. The truck is available for inspection. How was your safety or the safety of others put at risk? my truck lost all power while I was driving, which put me and other drivers at risk because it happened without warning. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. The dealer inspected the truck and confirmed the engine had an internal failure. They found metal in the engine oil and oil filter and said the engine must be replaced. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? the truck has been inspected by the dealer. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? no. There were no warning lights, messages, or other signs of a problem before the engine failed.

2026 chevy silverado high country with 13,193 miles 6. 2 engine locked up on 7/29/26 and is currently at my dealer waiting on engine replacment. Gm has not fixed the 6. 2 liter engine failure issue's!.

The engine began to make a metallic screeching sound and began to loose power. Stopped on side of road and was towed to dealer. Dealer indicated there was metal in the oil filter. Engine was replaced.

The engine (6. 2 liter) on my Chevrolet silverado fail with less than 2335 miles. It was confirmed my the Chevrolet dealership(hendricks Chevrolet ). No warning lamps appeared in the dash or warning from my onstar maintenance notification.

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.

The 2026 chevy 1500 silverado 6. 2l engine had a slight knocking sound from the date I purchased it brand new in March 2026. I was driving home on a evening in July 2026 and the truck began to squeak, knock very loudly and shake violently. The truck then locked up and completely shut off while I was driving 45 mph down the highway. The vehicle had approximately 3,000 miles on it when the incident occurred. The truck’s violent shaking and sudden loss of power while traveling 45 mph created an immediate risk in which I did not have control of the vehicle and could have caused me to be unable to safely maneuver out of traffic. Thank god there was light traffic at the time and also a wide empty parking lot straight ahead of me when the truck shut down. The incident also placed other drivers in danger of colliding with my disabled vehicle or taking sudden evasive action that could cause an accident. I had it towed directly to the dealership service department and according to their report, "found catastrophic internal engine failure. ".

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).

A. The engine is stalling while driving. This has happened four different times. Three times while towing, and one time while backing up a small hill. This is a scary situation because three of the four times almost caused an accident. 1. We were driving to texas, pulling a pontoon boat. While exiting the highway, we were entering into an intersection at a speed of about 10 miles per hour, and the truck shut down. The truck said, “start the motor and place it into gear. ” or something similar to that. 2. We were in stop-and-go traffic on the highway, and the truck shut down. Once again, I had to restart the motor and shift into gear. 3. We were entering a parking lot from the main road, and the truck shut down. Again, I had to restart the motor and shift into gear. 4. The three times above are during a time when we were towing. The fourth time is when we were backing up a small hill. The rear tires lost traction and spun for a second or two, and then the truck shut down and started to roll forward. Once again, I had to restart the motor and place it into gear.

While driving my truck returning from a camping trip I received the following warnings in the dash: service esc, service traction control, forward collision system unavailable. Check engine light was flashing. I made the assumption that the check engine light was due to the warnings listed above. I continued to drive the vehicle until I began to feel a very noticeable shudder at idle, at low speeds, and also loss of power at higher speeds. The truck has the 5. 3 ecotec engine with dfm. After researching the symptoms, I found that these symptoms are identical to the know lifter problem with that engine. The truck is a 2026 Chevrolet silverado trail boss with approx. 3454 miles on it. It's currently at the dealership waiting for them to "diagnose" the problem. I was told that it may just be a "faulty sensor", but after reading other people's experience with this engine I believe that the real problem is a damaged lifter/lifter pin due to the poor design and engineering of the dfm system.

At approximately 3,000 miles, the engine began making a loud knocking noise that became progressively worse while driving. The truck was diagnosed as needing a complete engine replacement. No warning lights, no check engine light, nothing. For someone inexperienced with vehicles, you could easily be in big trouble on the highway and a potentially life threatening situation. My primary concern is that there was no warning that such a major engine failure was about to occur. An engine that fails with so few miles raises concerns about the possibility of sudden loss of power, loss of acceleration, or engine seizure while driving in traffic, on highways, or while towing. A failure under those conditions could significantly increase the risk of a crash. The vehicle has been out of service while I continue making loan and insurance payments on a brand-new truck that I cannot use. The replacement engine is on national backorder, leaving me without a clear repair timeline. After researching this issue, I found numerous reports from other owners describing similar failures involving the 6. 2l v8 engine. Based on the volume of owner complaints, there appears to have been a significant increase in reported engine failures involving 2026 model-year vehicles. This suggests the problem may not be an isolated incident but instead could indicate a broader defect that deserves investigation. As a result of this experience, I no longer feel confident or safe driving this vehicle, even if the engine is replaced. I purchased a brand-new truck expecting long-term reliability and peace of mind, but instead I experienced catastrophic engine failure at only 3,000 miles. I respectfully request that NHTSA investigate these engine failures to determine whether a safety-related defect exists and whether further action is necessary to protect consumers. I have requested a buyback, but gm completely denies it. Such a horrible expy with manufacture.

On Monday, June 29, 2026, I was getting off the new jersey garden state parkway. I was halfway down the exit ramp and the engine and the engine just stopped. I coasted to the bottom of the exit ramp and luckily had just enough shoulder to pull over to get out of traffic. Once stopped, I attempted to start my 2026 chevy silverado, but all attempts at starting the engine were fruitless, as the engine would not even turn over when tried. I contacted on star and a tow truck was sent to tow my truck to burke, the gm dealer I purchased the truck from. It was confirmed by burke gm on Wednesday, July 1, 2026, that the truck needed the engine replaced. The truck is currently at burke gm and I have been there to get belongings out of the truck so yes, I would say it’s safe to assume that it is available for inspection. There were no warning signs of any problem with the motor at all.

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.

This incident occurred 24, June 2024. Time was approx 1745hrs and temperature was 93 and humid. Was stopped at a stop sign, attempted to make a phone call and reached to temporarily turn off the air conditioner by pushing the on/off button. When I pushed the button, it turned off the vehicle engine completely! when I was startled as to what had just happened, I pushed the air conditioner button a second time; it started the truck's vehicle engine! I repeated this test three times in the presence of my spouse who was also in the truck. We then drove approximately one mile and at a second stop again was able to duplicate the engine turned off/on by pushing the air conditioner on off again! it was if the air conditioner on/off button was the vehicle start stop button. I did not try to duplicate this under roadway speed, fearing if the engine did in fact turn off, simply by pushing the on/off air conditioner button. It would most assuredly result in the complete loss of driver inputs for steering, brakes and control.
