2025 Chevrolet Silverado 1500 Engine Problems

The engine started making a ticking noise and getting a little louder while driving to dealer where I had purchased the veichle and had it serviced as called for . They had me leave to check it out , they called me 2 hrs later and said it would need a new engine and it had a spun crankshaft bearing and would be 3 weeks to get the new engine . They said my warranty would cover the billing . I’m presently waiting to hear from them . They told me that the new engine would have a warranty but minus the 31615 miles that my odometer reads now ?

The engine has been using atleast 1 quart of oil every 2000 miles. This is put my maintenance cost way above the estimated maintenance cost projected by the manufacturer This oil usage is also causing premature engine wear as it's a quart low every 2000 miles. Dealer responses was this is normal for this engine. I went back and forth with the about estimated maintenance cost and ofcourse there responses was it estimated, well that's a very inaccurate estimate or willful lie. Idk just not happy about it.

There have been multiple instances of engine ticking upon start up. I have 4 videos with sound. I can provide a link if necessary to dropbox or google drive if necessary since there is no way to upload them to this site. This has been reported by GM 6.2L owners as being a precursor to engine failure. I have not had the sound confirmed by a dealer or service center. The vehicle has not been inspected. There have been no warning lamps.

The engine in my truck had a catastrophic failure (6.2 litre), same as the thousands with the same problem / failure. It had to be towed to the dealership where it underwent a complete engine replacement... it had 8,906 miles on it at the time of the engine failure. It died after making horrendous and loud noise, I was able to coast for a short distance but it came to a stop in the middle of a residential street and had to be towed to a safe location until the dealership could pick it up and tow it to their facility for diagnostics and repairs. I have the invoice with detailed information of the repairs and parts used.

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.

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.

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.

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.
