2025 Chevrolet Silverado Engine Problems

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated that while starting the vehicle remotely, an abnormal grinding and banging sound was heard emanating from the engine compartment. The vehicle independently shut off. The contact attempted to restart the vehicle remotely, but the vehicle shut off again. The contact then attempted to start the vehicle manually, but the vehicle failed to start. The vehicle was towed to the dealer, where it was diagnosed that the engine had failed and needed replacement. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 5,425.

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.

After having the original '25 6.2L GM L87 engine experience crankshaft bearing failure at approx. 5,700 mi, (previously reported to the NHTSA), the (brand new) replacement engine failed approx. 14,000 mi. later for the exact same reason, crankshaft bearing failure. In both incidents, the failure came 100% without warning, and the transmission LOCKED itself into park, leaving the vehicle and myself dangerously stranded in the middle of the highway; it had to be dragged on and off of the flat-bed tow truck both times.

The engine check appeared on dashboard then engine did not start, Vehicle towed to dealership. Where they discovered a lift pin had broke. A new engine was ordered. Details on incident: I driving on I88 at 70 mile per hour when my vehicle when from 70 to 30 with engine check flashing running rough. After pulling off to side of the HWY, turn-off the engine and calling for help. I decided to try the engine again and it started after about 10 minutes with message "proceed with caution" so drove it to near Chevrolet dealership. Once arrived the Service Advisor saw the engine light and pulled two code. Nevertheless, They were not able find the source of the problem. I drove the vehicle home and two days later I drove the vehicle 20 miles and parked it at locate near me. When came out the vehicle would not start & was towed to the dealership. To some like what I written above is very damage situation

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!

Engine crank bearings failed at only 16,310 miles. Engine replaced with a new one due severe internal damage.

I HAD A 2020 CHEVY TRAIL BOSS AND THE PISTON ROD BROKE. CHEVY STATED I NEEDED A NEW MOTOR. AT THE TIME IT WAS 5 WEEKS OR MORE TO GET FIXED. I TRADED IT IN FOR THE SAME STYLE TRUCK BECAUSE I WAS ON VACATION AND NEEDED TO GET HOME. (2025 WITH THE L87 6.2 MOTOR). MY NEW TRUCK HAS 21000 MILES ON IT AND I HAVE BEEN NOTICING A ROUGHER IDLE, OIL USE BETWEEN OIL CHANGES, AND METAL DEBRIE IN THE OIL AND OIL FILTER. I’M AFRAID THIS NEW TRUCK WILL BLOW UP TOO. I LOST MONEY ON THE 2020 TRUCK AND NOW IT LOOKS LIKE THE SAME IS HAPPENING TO MY NEW ONE.

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.

I was driving my 2025 Chevy Silverado RST L87 (6.2) with 37,836 miles on the highway and suddenly my engine lost power and my dash said “Needs to restart”. My truck went into neutral and I was able to coast off of the highway. After coming to a complete stop, I tried to restart with no success. I had the vehicle towed to the dealership where they found metal shavings in the engine and told me I’m going to need a new engine.

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.

Took 2025 Silverado with a 6.2L engine to get oil changed and tire rotation done. Upon completion drove out of dealership and notice a weird noise coming from engine, then kind of disappeared. Drove home. Wife took car for gym then suppose to go to work. She called stating engine sounded really bad, like a lot of metal and metal screeching. Went to dealership, explained and they towed truck to service department to be looked at on 12/22/2025. Safety to others would have been detrimental if the vehicle had seized on the highway. The dealer person who sent for the tow was not the service manager but when we arrived he heard what the vehicle sounded like. No check engine lights or any warnings on. Hope to have results on Monday.

The thrust bearing of 3.0l diesel engine is out of spec engine knocking there was no check engine lights on. The safety of this problem is I was at the cancer facility with my other half while she was getting chemotherapy when this started so I left her there went home and got are other vehicle

Catastrophic Engine Failure - 4500 miles Driving on the highway, truck suddenly lost power (limp mode) and started flashing warning related to low power and oil level issues. The vehicle was towed, and spent 43 days in the shop waiting for a complete engine replacement.

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.
