2025 Chevrolet Silverado owner complaints

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 th

2025 Chevrolet 1500 Silverado High Country 6.2 L motor with 5624 miles blown motor. When I tried to start it, the motor made a noise like someone tossed a handful of spoons in a blender and turned it on. Motor shut off on its own. This was on Sunday December 21st of 2025. Truck as towed to Westly Chapel Chevrolet in Westly Chapel Florida on Monday December 22nd of 2025. Chevrolet Customer Service was called on Monday December 22nd of 2025. The Case # XXX. I spoke to 7 different people before a manager called me later that evening and said my case manager will be Tyisha. The manager stated she was Tyisha's direct manager and that Tyisha would reach out to me within 2-3 days. The manager also stated that she was unaware of the 2021-2024 issues with the 6.2 L motor. I informed Customer Ser

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.

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.

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.

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.

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.

Metal shavings in oil and oil filter during routine maintenance at Hamilton Chevrolet. Needs entire engine replaced. I have been told that this is an issue with the 6.2L motor

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.

Shifting thru lower gears was irregular in lower gears 12/02/2025. Made appointment with dealer on 12/04/2025 they could not duplicate. 12/16/2025 Reverse would not work. Tried to take to dealer and couldn't go over thirty mile per hour without transmission jerking. was towed to dealer on 12/17/2025. it's been there since.

Purchased new and after 3 weeks (about 600 miles) I was on highway between 60-70 MPH truck started to shutter like it was losing power and would not accelerate. I complained to the sales person and he stated it ran a little rough when purchased first day - I was told it just needs to warm up. Took truck to dealer and they determined at this time it was a misfire and lifter bank issue. There seems to be an issue widespread - I am not comfortable with car and if on the highway i am not able to accelerate properly or becomes unreliable at the time to accelerate I am worried about safety.

There is a reoccurring issue where vehicle will stop functioning bring up a error to service every component on the vehicle and is completely random when it occurs and dealers have not been able to replicate it after 4 visits

At random times when you start the vehicle there is no sound. No sound from the turn signals, radio, emergency flashers. Apple Car Play. You have to restart the vehicle to have it reset. You always do not know there is no sound until you have started to drive and go to use the radio of notice that the turn signal is not working. I did not realize that my left hand turn signal did not turn off and at a traffic light I was going straight and a car turn in front of me because they assumed I was making a left hand turn. There was not an accident because they were able to stop. I have had it back to the dealership a number of times. They reset the system. Said it needed a global reset. Even after the reset it still is doing this. Happens more in cold weather. I have recording that ar

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated that while driving at various speeds on several occasions, there was discrepancy between the speed limit displayed on the infotainment system and the actual speed limit posted on the road. The contact sated that while driving at an undisclosed speed on a residential street, the infotainment system displayed that the speed limit was 55 MPH while the posted speed limit was significantly lower. The vehicle was taken to a dealer, where the failure was acknowledged, but the contact was informed that the remedy to correct the failure was not yet available. The manufacturer was notified of the failure. The failure mileage was approximately 75.

The vehicle experiences intermittent 1-to-2-second total audio dropouts across all stereo sources, including the turn signals, radio and Apple CarPlay. Because the vehicle generates and routes audible safety alerts through the infotainment module and audio amplifier, the audible turn signal indicator (blinker clicking sound) and critical driver safety chimes (forward collision alert, backup park assist, and seatbelt warnings) fail to sound during these cutouts. The infotainment system is already running software build W231E-Y181.3.2-SIHM22B-499.3 231 release-keys, and the intermittent loss of turn signal and safety chimes persists. Per GM Bulletin PIT6406, dealerships are instructed not to replace the radio or amplifier while GM Engineering investigates, leaving the vehicle with an unresol

The radio system is severely defective, exhibiting: •Complete loss of sound with no audio output •Severe crackling and static when sound does work •Intermittent failures that create safety concerns when navigation or hands-free calling fails. Turn signals have no sound or alerts from collision warnings, parking, rear cross traffic

Driving to work, heard a loud pop, pulled over and the truck was on fire. There were no other warnings. Insurance has deemed it a total loss and the fire inspection team is handling it. GM has been contacted and I am waiting to hear their report.

Turn signal sound intermittently fails along with all sound to the radio, phone, warning sounds, all audio feedback fails. GM is aware and does not have a fix.
