2025 Chevrolet Silverado 1500

On Thursday, July 9, 2026, at approximately 2:30 p.m., I was driving my 2025 Chevrolet Silverado 1500 Duramax on Highway 40 while towing a properly connected trailer. The Multi-Flex tailgate had been fully closed and latched before I began my trip and had not been opened at any point prior to the incident. While traveling on the highway, a California Highway Patrol officer pulled alongside my vehicle and alerted me that my tailgate was down and bouncing on the trailer I was towing. I immediately pulled over to the shoulder and observed that the entire Multi-Flex tailgate had unexpectedly unlatched and was resting on the trailer. I closed and latched the tailgate, which appeared to operate normally, and continued to my destination. At no time before or during the incident did the vehicle display a "Tailgate Open" warning or any other warning message on the instrument cluster. The unexpected opening of the tailgate caused it to strike the trailer, resulting in damage to the Multi-Flex tailgate, the rear bumper, and the trailer. The vehicle has approximately 11,000 miles, was purchased new, and has not been modified. I have opened a case with General Motors, and the vehicle is scheduled to be inspected by an authorized Chevrolet dealership.

My truck (2025 Chevy Silverado Trail Boss LZ0 Duramax 3.0l) started to have problems when driving. At a stop light, I started to accelerate at about 2000-3000 RPM. While doing so, there was a loud ticking/grinding noise coming from the transmission/Bell housing area. On June 2nd, I dropped the truck off with the dealership. I didn’t hear back from them until about a month later (July 3rd) and when I did they said the technician confirmed I needed a new ‘axle actuator’. About a week and a half later, they said it did not fix the issue and started to become more of a problem to where they will need an “engine technician” to see if I need a new engine due to the “crank shaft thrust bearing”. The advisor said he will call me on Wednesday, July 15th to update me on what I will need. I requested a Loaner vehicle since I dropped it off and they said no because the dealer does not provide that and would have to get approval from GM to grant me the loaner vehicle bast off the diagnostic.

Leased a 2025 Chevy Silverado in late 2025. On June 13th 2026 driving home my vehicle all of a sudden had very little power, check engine light went on and thankfully I was at my driveway. Pulled into my residence, shut truck off and called the dealer I leased the truck from at 1:00 pm Satuarday, June 13th. They set me up with a loaner vehicle. I called for a tow truck Monday the June 15th and had truck delivered to dealership. Ive been told, they are looking into? Beyond that, nothing more.

My 2025 Chevy Silverado 1500 6.2L V8 experienced an internal engine failure at approximately 16,500 miles, requiring replacement of the entire long block under the factory powertrain warranty. The authorized Chevrolet dealership diagnosed internal cylinder wall scoring, and the engine could not be repaired. The failed engine should still be available for inspection if requested. About 4,000 miles after my last oil change, while the Oil Life Monitor still showed about 50% remaining, the vehicle repeatedly displayed "Engine Oil Level Low" warnings. I checked the oil level with the engine cold, and the dipstick showed the level was normal, so I believed the problem was a faulty oil level sensor. The next day, the warning changed to "Add Engine Oil," and I immediately took the truck to the dealership. The dealership confirmed the issue was not the sensor but internal engine damage caused by cylinder wall scoring, requiring replacement of the entire long block. Fortunately, the engine did not seize while I was driving, and no crash or injury occurred. However, before the failure was diagnosed, the only warning was repeated oil level messages that did not match the actual oil level. There were no abnormal engine noises, knocking, or noticeable loss of power. A driver could reasonably assume it was only a sensor issue and continue driving without realizing the engine had already suffered severe internal damage. If the engine failed while driving, it could create a serious safety hazard. Although GM replaced the engine under warranty, I remain concerned that a vehicle less than 16 months old with only 16,500 miles experienced such a major engine failure. I am also concerned that similar failures could occur after the factory powertrain warranty expires, leaving owners responsible for repairs that other Silverado owners have reported can cost approximately $13,000. I respectfully request that NHTSA investigate whether similar failures may also affect 2025 6.2L V8 model.

Date: June 22, 2026 Time of Incident: Approximately 11:48 a.m. Vehicle: 2025 Chevrolet Silverado High Country 6.2L V8 Current Mileage: Approximately 29,500 miles I am documenting the events surrounding the unexpected engine failure of my 2025 Chevrolet Silverado High Country. On June 22, 2026, at approximately 11:48 a.m., while driving at highway speed, the vehicle was operating normally with no warning lights, messages, or other indications of a problem. I began hearing a metallic clanking or knocking noise from the engine area. The noise progressively increased in volume and severity over approximately ten minutes as I reduced speed and looked for a safe location to pull over. My intention was to reach the dealership if possible; however, as I slowed to approximately 15 mph to make a turn, the noise stopped abruptly, the engine shut off, and the vehicle displayed a message instructing me to press the Start button again. The vehicle came to a complete stop at approximately 11:58 a.m. I attempted to restart the vehicle once, but it did not restart. No additional restart attempts have been made. There were no warning lights displayed prior to the engine shutting down, and there were no visible fluid leaks underneath the vehicle after it came to a stop. The vehicle received a routine oil change on June 16, 2026, approximately three days before this incident. I have retained the service receipt and all related documentation. The vehicle will be transported by flatbed tow truck to an authorized Chevrolet dealership for diagnosis and repair under warranty. This email is intended to document the incident timeline and details while they are fresh in my memory. I have not heard back from the dealer yet.

1st incident My son was driving the truck when all the emergency lights came on. He pulled over and the engine was on fire. He ran to a strangers house to get buckets of water not safe for my child at all. Come to find out that an engine rod slipped and put three holes through the engine causing oil to spill and a fire unbelievable! Lucky my son wasn’t injured. Chevy blames my son for that! Not acceptable! 2nd incident 1 month later my son calls and tells me when he started the truck it began making noise. He again got stuck with this truck because it lost complete power. Come to find out the transmission went. Chevy blamed my son again! Really come on! We have paid more for this truck than drive it. Now they are taking the warranty away. Please help.

A failed DC/DC converter module was discovered immediately after the latest round of repairs when the dashboard lit up with multiple warning lights and a check engine light the same day I picked up the vehicle. I drive this truck daily for work and transport my young child in it regularly. Repeated unexpected failures create a serious and ongoing safety risk. Confirmed by dealer: Yes. George Chevrolet confirmed and attempted repairs on the telematics module, DC/DC converter module, and radio. All failures documented on official repair orders. Warning lamps: Yes. Multiple warning lights and check engine light appeared immediately upon pickup after the most recent repairs. Manufacturer response: General Motors denied my repurchase request despite multiple confirmed warranty failures and has not offered a replacement vehicle.

Hello, I purchased this truck new in November of 2025. Around 1500 miles and a few months later the truck developed what sounds like some sort of belt squeak or chirp upon startup, light acceleration and when the engine auto start/stops. I took it to my local dealer and they told me they “lubed the belt” the noise became faint but still didn’t go away. Around 3k miles the noise is back as loud as it was. Back to the dealer, a new serpentine belt the noise is again quieter but still exists. This needs to be addressed many people online are dealing with this and the dealer is giving us the run around trying to say it’s normal for a brand new $70,000 dollar truck to squeak and chirp!

My vehicle was in motion down a state highway at approximately 55 mph around a corner as my 6.2 put itself into neutral and shut itself off. A message displayed on my dash stating to press start again to restart the engine. I pulled to the side of the road and attempted to do so in which nothing happened. Vehicle was towed to the dealer the same day. I was on a blind corner, experiencing complete engine failure on a busy state highway, I was near inches from being hit multiple times and sent off of a roughly 30 foot drop. My 6.2 experiencing complete engine failure at approximately 33000 miles should not be happening. The engine had no warning signs just happened traveling down the road. The dealership has ordered my engine under warranty but I remain well over 1000 on the waiting list to get a new 6.2 engine. My main concern is what happens when I get the truck back with the same malfunctioning 6.2 with no recall and no fix. How long until it breaks again? GM has done nothing else to remedy the situation and make the situation better for their loyal customers. Vehicle has been in the shop since 03/18 and has no return in the foreseeable future.

The check engine light went on and I later found out it was the valve body that caused it. This could have cause serious harm to my family had I not maintained control of the vehicle. The dealership fixed the problem only for it to happen again a month later. The truck is still in the shop.

On March 6, 2026 exactly one month ago from today, I was driving my Chevrolet Silverado 1500 ZR2 with a 6.2 liter gas engine to a family vacation. We were traveling through our home state to another state. I was driving and my wife, along wiht two children (age [XXX] and [XXX] ) and my family dog were all riding inside the truck. We were traveling at posted highway speed approximately three hours from our home. There was a whine from the engine compartment that got progressively louder in about 30 seconds. Then the engine began to lose power. We were near a chevrolet dealer so I pulled in the service bay, where the technician swiftly told me to cut off the engine, that my crankshaft was broken and it lead to catastrophic engine failure. The vehicle is available for inspection at the same Chevrolet dealer we visited one month ago. My family's safety was put at risk because we were traveling at highway speed and the vehicle witnessed catastrophic engine failure. Due to catastrophic engine failure, the engine has not been turned on by the dealer since departing the service department. The vehicle was been inspected by the service department at a certified Chevrolet dealer. Interestingly, there were no warning lights or any type of warning other than the severe sound coming from the engine compartment. Prior to engine failure, there were no other symptoms of the problem other than the low pitched whine that progressively got louder over a 30 second period of time.

while driving down the freeway at 80 mph, in my 2025 Chevy truck with 6000 mikes , the truck suddenly locked up, almost throwing myself and my daughter into the dash, thank goodness the semi truck behind us was paying attention of we would be dead! I was able to steer it to the shoulder of the road where I unhooked the battery hoping to reset the system to no avail. Waited on the side of the road till the tow truck got there. towed the truck to my local Chevy dealer where they confirmed the engine was blown, I want Chevy to do a buyback on the truck as I have zero confidence in the truck, do not feel safe in it anymore, my daughter swore to never set foot in it again after such a dramatic event. i now have to wait a month for the dealer to install a new motor, at which time they will not give me a loaner truck, very disappointing. 1-Total engine failure. 2-Mine, my daughter, the semi truck driver, and many other surrounding drivers safety and lives were put at risk. 3- Yes the dealer has confirmed it was a totally engine loss. 4-no one else has inspected the vehicle 5- No light, sensors or warnings just a loud bang then our lives flashing before our eyes.

My vehicle frequently loses all cabin sound, including the radio, audible turn signal, and forward/rear collision and lane departure warnings. When this occurs, the cabin is completely silent. The loss of radio audio is an inconvenience, but the loss of safety feature alerts is a clear hazard. My dealership has suggested this may be related to a recent software update; however, there is no apparent correlation between the updates and when the issue occurs.

I have had my vehicle to a GM dealership three times now due to the check engine light coming on and getting an emission warning. 2/13/26 was the first visit. It was right after I filled up my tank with gas that the check engine light came on when I started driving down the road. I got an appointment at a GM dealership. They put the scanner on it and received the codes. They drove it back to the service garage and I went back to work. I received information from them that they could not fix anything because the check engine light had disappeared and there were no codes available anymore. I picked up my vehicle and a week later 2/20/26 the same thing happened after I got gas. The check engine light came on and an emission warning on my Chevy app. I stopped back into the same dealership. And the same thing happened. Scanner, codes, and then they disappeared. The third time I got gas the same thing happened again with the check engine light and emission system warning. This was on 2/28/2026. I went to a different dealership and the exact same thing happened..... scanner, codes received, schedule an appointment to get it in the following week, started the vehicle and pulled out. The check engine light was still on at that time. And the check engine light disappeared once again as I was driving down the road. Each time this has happened I have been able to use my remote start via my Chevy app along with trying to use my handheld key fob remote start. The dealerships have told me this is normal for this type of check engine light emission warning. When researching this issue there are a lot of people experiencing the same thing. Scratching my head wondering why there's not a recall on this.

What component or system failed or malfunctioned, and is it available for inspection upon request? The engine in my 2025 Chevrolet Silverado 1500 experienced a catastrophic internal failure caused by a failed thrust bearing in the crankshaft assembly. The failure caused the engine to stop operating immediately and without warning. The vehicle and engine are currently at a dealership/service facility and the failed components should be available for inspection upon request. How was your safety or the safety of others put at risk? The engine failed suddenly while the vehicle was being driven through an intersection, causing the vehicle to stall and lose power in active traffic. This left my family stranded in the middle of the roadway with vehicles approaching from multiple directions. Because the engine failure occurred without warning, we were unable to move the vehicle out of the intersection immediately, creating a serious risk of a collision with other vehicles. Has the problem been reproduced or confirmed by a dealer or independent service center? The failure has been inspected and confirmed by the dealership/service center, which determined that the engine experienced a thrust bearing failure leading to catastrophic engine damage and loss of power. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? At this time, the vehicle has been inspected by the dealership/service department. The vehicle remains available for further inspection by the manufacturer or other parties if requested. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lights, messages, or noticeable symptoms prior to the engine failure. The vehicle was operating normally immediately before the incident. The engine shut down suddenly and without any prior indication that a mechanical failure was imminent.

Driving 30 mph down a city street when heard a pop and vehicle completely lost power at speed. Engine turned off and I coasted to a stop, which was unfortunately at an intersection and due to traffic could not get over safely. All accessories were still on however I could not restart the vehicle or put the vehicle into neutral, which left me stranded in the middle of a busy intersection. Hazards were working intermittently, at best. Had to call local PD to provide traffic control while we disconnected the battery and reconnected it while standing in an intersection. After I was able to get the vehicle restarted it had a check engine light and the OnStar app showed Transmission, Ignition, and Engine Electrical warnings. Had the vehicle towed to the dealership, where they have had it for 7 days and cannot diagnose an issue and are trying to return the vehicle to me unfixed. They stated they typically would not even try to diagnose it for this long, however I have a case open with the GM executive team.

Was able to get home but the next time the truck was started there was a check engine light and the vehicle was unable to shift into reverse gear. When attempting to put it into reverse, it gives the error "conditions not correct to shift" and turn on the parking break. Trying to drive it with this issue is unsafe.

I have taken my vehicle to the dealership, Preston, Hood Chevrolet, Fort Walton Beach, Florida. The problem I’m having is the avoidance system! Not getting warning nor will the vehicle stop an emergency situation where I’m going forward in a vehicle stops quickly in front of me nor will it work if a person is walking behind my vehicle or if there’s a vehicle behind my vehicle when I’m backing out of my driveway. They keep telling me everything checks out on the computer and they keep saying it’s normal and it’s only meant to possibly slow down the vehicle before a crash. They do not give me any definitive answer and they also escalated to GM response is basically the same thing. You can read all over the Internet that a lot of people have this problems. I have friends that own the same truck and it works perfectly. My truck will not. It’s very frustrating because one of the reasons why I bought a new vehicle like this was for those safety reasons. Also, when I am pulling out of a parking spot and turning the wheel, the truck accelerates by itself and goes into cruise control. Only doing a few miles per hour. And this might be because of the location of the activation of the cruise control switch. It is a lever on the steering wheel and it’s easily to engage. And I don’t understand why it would engage at such a slow speed. I’ve had several situations where a vehicle has stopped suddenly in front of me and my truck will not respond at all with a late morning shaking of the seats no alarm and no breaking luckily I was able to stop in time with my own reaction. The technicians will not work on this because the computer says it’s OK. It seems like they have technicians but not mechanics. My opinion. I spent a lot of money for this truck and I’m [XXX] although my reactions are still pretty good. I’m looking at a vehicle that will assist if I do not react. This vehicle doesn’t react and I paid for this and I am afraid when I need the avoidance system, it won’t work.

Prior to this incident, I had been having issues with my fuel management system give a “reduced acceleration” warning (codes P0087, P228B) in weather below 28-30F. It was in the shop 3 times prior: first time was “bad fuel”, second had my fuel rail and fuel filter replaced, and third time I had my high pressure fuel pump replaced (also had a rear crank seal leak). While approaching a stop sign, my vehicle gave me a check engine light with a “Reduced Acceleration” warning followed by several other warning messages and then ultimately lost power and shut off give me no ability to steer or brake my vehicle. Luckily, my vehicle came to stop and no crash or injuries occurred. If this had been at higher speeds the outcome could have been fatal to myself or another driver/passenger on the road. This incident also gave me a P0087, P12A6, P228A, and P228B error codes. I was able to restart the vehicle and make it home. The following day, the “Reduced Acceleration” message once again appeared. The vehicle is currently at the dealer awaiting diagnosis and repair.

While driving to work on [XXX] in Huntsville AL at approximately 55MPH. I was using Chevrolet SuperCruise. I tried turning off super cruise with the super cruise button. It did not turn off, tried pressing cruise control button, nothing, tried the cancel button, nothing, pressed brakes and would not turn off. Truck started slowing in very heavy traffic, it turned hazards on. I was finally able to get it turned off. I have reported to dealer, no surprise they didn't answer, left message at 9 am this morning, no call back. I have made a report to GM. I no longer feel safe putting my family in this truck. This truck has been in shop several times for "Service driver assist", no on-star, no cellular data, extremely slow infotainment system and no supercruise available. The truck at last visit for the service driver assist took more than 2 week. I was told a camera and a software update were performed. The issues have persisted. The super cruise event yesterday was the first occurrence of this type. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle’s wireless Apple CarPlay system forces the iPhone to connect to the truck’s built-in Wi-Fi network, which does not provide internet access. When connected, iPhone cellular data is blocked, resulting in frequent loss of navigation, traffic updates, and streaming services while driving. There is no option in the vehicle settings to disable the Wi-Fi or force cellular use. Multiple troubleshooting steps have been attempted, including iPhone network resets, Wi-Fi assist, toggling data settings, and re-pairing CarPlay, all without success. This design flaw creates a safety concern because navigation and real-time traffic information can fail unexpectedly, requiring driver distraction to troubleshoot or rely on a handheld device. The issue appears to be a firmware or design limitation of the infotainment system, not a defect with the phone. Using wired CarPlay resolves the issue, but wireless CarPlay as advertised consistently blocks cellular data. I am filing this complaint to report a persistent connectivity and safety problem that affects all users of wireless CarPlay on this vehicle model. The inability to access real-time navigation and traffic data while driving is a clear distraction and could contribute to unsafe driving conditions.

On 11-20-25 while driving vehicle home a loud noise was heard coming from rear of engine. After review and consultation with automative technician it was thought best to park truck in safe location at house and have towed to dealership as engine noise identified aligned with other reports of thrust bearing failures associated with this engine. Driving engine further was considered unsafe if further damage occurred the engine could seize up while on highway. The Dealership tested engine on 11-21-25 in accordance with GM technical service bulletin and confirmed a thrust bearing failure had occurred. A replacement engine and turbo were submitted for order, but not available to due to back order of these parts due to large number of failures of same engine this year. Only the GM dealership that I purchased car from has inspected vehicle at this time and there were no check engine lights in vehicle when failure occurred. I have since identified the GM technical service bulletin was published in September of 2025 and the Duramax 3.0 has had numerous failures throughout 2025, prior to my purchasing vehicle at end of October. GM manufacturing misrepresented the quality of vehicle during the new vehicle purchase and did not disclose the significant number of engine failures that have occurred this year that could have left me and my family in an extremely unsafe situation. Additionally there has been no communication on how the replacement engine equipment manufacturing has resolved the issue that created the initial failure and I am concerned of driving vehicle in future as the engine failure may occur again. NHTSA needs to record this incident and request to GM failure rate data this year and investigate GM for selling vehicles with known manufacturing issues that place driver/passengers in an unsafe condition when vehicle looses power while driving.
