general problems of the 2025 Chevrolet Silverado 1500 - part 2

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.

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.

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.

I had just received my truck back from a complete engine replacement from the dealer and had driven it 10 miles back to my house and the check engine light came on and the dash said reduced power service dpf system. The truck was towed to dealer for po302 code and injector #3 was replaced.

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated that the infotainment screen failed to turn off. The contact became aware that the bluetooth had failed to remain connected. The vehicle was taken to the dealer, who diagnosed that the infotainment center had failed and needed to be replaced. The infotainment center was replaced. After having the repair completed, the contact became aware that the check engine warning light was illuminated, and the message “engine power reduced” was displayed. The vehicle was returned to the dealer, who diagnosed that the engine had failed due to thrust bearing failures. The contact was informed that the engine needed to be replaced. The engine was replaced. The vehicle was only owned for 3 months when the engine completely failed and needed to be replaced. The manufacturer was informed of the failure and opened a case for the failure. The failure mileage was approximately 3,000.

Traveling at 75 mph on highway truck went into reduced acceleration mode putting my wife and I in danger. There were many simi trucks having to swerve as my vehicle reduced speed at a high rate and was unable to safetly come to a stop. There was a bulletin released prior to my purchase that was not disclosed that could have warned of potential danger of complete engine loss. Was told by dealership engine grenaded dealership confirmed needed new engine and turbo and they are on back order which leads me to believe that I am not the only one this has happened to.

6 weeks since purchase and only 2000 miles-engine suddenly made a horrible rattling noise and stalled. Towed to dealership and was told engine was dead and needed replacement.

I purchased the vehicle on 8-23-25. On 10-23-25 while driving my daughter to school I received a message on the dashboard that said "reduced acceleration mode drive with care. " I immediately drove to the dealership. After a few hours I was told by the dealer that the diagnostic code of po6dd "engine oil pressure control solenoid valve stuck off" had been recorded and a full engine replacement will be required. The vehicle has 3307 miles on it and has been at the dealership since. Engines for this vehicle are on back order and there is no timeframe available on when a new engine will be available.

Infotainment center and navigation and bluetooth with phone problem started on the way home from the dealer same day it was purchased , 3. 0 diesel engine failed at 7000 miles.

I was driving down the highway with my children to see a movie when my trucks check engine light came on and started surging and losing power we were struggling to drive 5 mph on the shoulder of the road to make it to the closest exit ramp for a safe place to stop. We were able to make it to the ramp but couldn't exit completely because it was an up hill grade. The vehicle was towed to the dealer for a complete engine replacement. The vehicle suffered from a thrust bearing failure.

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.

On the evening of August 27, 25, when exiting the highway ramp, the vehicle's engine suddenly stopped and stalled, the gear automatically shifted to neutral, and the hazard lights could not be turned on. After about 2 minutes, it restarted normally and turned on the hazard lights.

At 5,750 mi. The 6. 2 gas engine seized due to connecting rod bearings. The dealer replaced the engine, cooling system and oil cooling system under warranty with a similar engine. I am of the opinion that it could have been at least partly due to the low viscosity motor oil that the manufacturer insists upon to maintain the factory warranty, 0-w20 synthetic, along with a poorly engineered fuel management system. Also, once the vehicle was stopped and put into park, the electronically controlled transmission refused to change gears, to be put into neutral, in order to be pushed out of traffic and on to a tow vehicle, it had to be dragged. The vehicle is extremely unreliable and a danger to the public.

When coming to a stop, the truck idols high before slowly going down. Seems unsafe as if is not wanting to stop. I am also hearing a chirping coming from under the hood.

My 2025 chevy silverado zr2 has experienced the same dangerous system failure five times. While driving, every warning light on the dash activates, I lose power steering, and the vehicle completely shuts down and won’t restart. This creates an extreme safety risk — the first failure happened on a local road, but most recently, it occurred while my family was driving out of state during a holiday. The truck has now been out of service for over 50 cumulative days across these repeated incidents. Gm has accepted a lemon law claim but has not resolved it, leaving me without a vehicle and no clear path forward. These systemic failures present serious risks to me, my family, and other drivers. The latest failure occurred in July 2025, and the vehicle remains at bill cramer Chevrolet in panama city beach, FL with no resolution. I am still making loan payments and paying for transportation out-of-pocket, without any support from the manufacturer.

I was driving home from a camping trip with my children when my truck occurred a reduce speed error on the dash and the truck went into limp mode. I found out through gm onstar that the truck threw a po6dd code. The vehicle was towed to dealer and the oil pressure valve was replaced and also a wiring harness.

The "auto-stop" feature of the engine apparently automatically turns itself on every time the engine is started. There is no warning light or other indication that it is on except a very small light on the switch to shut off. The auto-stop function itself is inherently unsafe because it shuts the engine off and doesn't restart it until the operator removes his foot from the brake. . . . -sometimes it takes several seconds to restart. If you take your foot off from the pedal and then put it back on and the vehicle rolls back a bit, it may not start at all, necessitating shifting to park and manually restarting the engine. If it does start late, the engine may surge and the vehicle will lurch ahead into traffic. I have had two close calls because of the "auto-stop", once causing a semi-trailer truck to veer away to miss me. Any driver that fails to disengage the auto-stop function on engine start is putting his own and other peoples lives in danger. No feature affecting engine on-off, vehicle speed, steering , or braking should ever be engaged without a specific command by the operator of the vehicle. When it is engaged, by the operator, an amber warning light should show on the dash panel and stay on as long as that automatic feature is engaged. If not, the vehicle manufacturer should be held totally and solely responsible for any accident that occurs as a result of that feature.

Days after purchasing the vehicle brand new back in 2023, it began having issues with what they thought was the new 4 cylinder mode working itself in or electrical shifting needed to be replaced… after numerous years of being stalled out on highways, unnecessary repairs made, lose of business revenue, and more. It turned out to be a faulty engine with bad bearings, & levers. Over time, got worse & left unseen causing it to officially blow. The shutdown modes prior were all left undetected or resolved by dealership service stations. After being told of suspicious knocking since only thousands of miles out on.
