ENGINE
While driving at a speed of approximately 55 MPH, the vehicle suddenly displayed a flashing check engine light, ESC error light and stability control warning light on the driver cluster. The vehicle made a loud series of noises and suddenly lost power. The loss of power reduced my ability to control the vehicles acceleration while in traffic creating an immediate traffic hazard. Garage recovered vehicle by tow and found lifter failure, camshaft and cam bearing damage with significant metal shavings throughout engine requiring engine replacement. Repair is estimated at $12,000

SERVICE BRAKES
I am the original owner of a 2015 chevrolet silverado 1500. The vehicle's brake vacuum pump has failed, resulting in a sudden, significant loss of power braking assist. This requires excessive pedal force to stop the vehicle, creating an immediate safety hazard and increasing the risk of a crash. General Motors previously issued special coverage adjustment N192210240 ( or N182202780 ) to address this specific component failure, extending warranty coverage to 10 years or 150,000 miles. I never received notification of this coverage or the potential safety defect. The dealership has confirmed the vacuum pump failure but denied coverage because the 10- year window has recently expired. I contacted GM Corporate on 12/16/2025 and 12/17/ 2025 they declined GoodWill Assistance. I believe it is unreasonable to deny coverage for a know safety defect on a vehicle owned by the original purchaser who was never properly notified of the extension on N182202780.

STEERING, POWER TRAIN
Torque converter needs to be replaced at about 35000 miles. Power steering rack needs replacing at 36000 miles. Both of which would be considered major repairs for a vehicle with such low mileage.

I have been complaining for the safety reasons and the location and other issues in car to onstar and Chevy for months. Went to Freeport Chevy dealer and changed oil, when I bought the car pre-approved but the when I went for the service they said no oil was changed since the car was new. And I have been paying for all the warranty and extended service but they said all oil change and others will cost approx $3200. They changed the oil but I have been seeing on the Chevy app filter was never changed and the car didn’t feel same after the service.

ENGINE
In January 2024, I experienced an engine failure in my 2021 Silverado with the 6.2 Engine. My VIN was not part of the recall affected VIN units built in 2021-2024, it seems to have been built a few months before the last affected group, In any case, I noticed the engine stumbling, and the check engine light came on. I was able to drive the truck home, and when I went to start it the next day, the check engine light was off, so I drove it, and the engine stumbled the check engine light came back on, so I took it to the dealer. They read the codes, and cylinder 5 was misfiring. When they put a scope in that cylinder, the cylinder walls were scored, and there was oil in the cylinder. At that point the dealer chose to replace the engine with a remanufactured engine with no additional warranty added, or any other remuneration for the inconvenience. They did not share with me any specific reason (Lifters / Camshaft / something else) for the engine failure.

ENGINE
November 28th 2025 we were coming down Logan canyon in Utah at 50 miles an hour when i was passing another vehicle on the left I felt a hard shift and a prompt came on the dash that said reduced acceleration. So as I was passing the vehicle I was pulling in front of them and lost the ability to accelerate or even hold speed. I passed the vehicle got in front of them and slowed down rapidly without any ability to control the speed of the truck. At this point when I would push the gas nothing would happen so I pulled off the side of the road. While we were sitting, there was suddenly a burning smell in the cab so we rolled down the windows and made sure the doors were unlocked in case we had to jump out. We sat there for a minute everything seemed fine I checked the accelerator and it was working again so we drove home. I immediately took the truck down to John Watson Chevrolet to have it looked at. I told the service writer what had happened and she said there was a code that had been thrown however there was nothing now and since everything seemed fine I shouldn’t worry about it because the computers trip pretty easily on these new trucks. I insisted on making an appointment so she scheduled me for Tuesday the second of December. I took the truck in just before 730 today the second of December. Christina from John Watson checked me in and told me she would let me know when my truck is ready. She called me at 12:34 but I missed so she called again at 1:18 to tell me that she had some news on my truck and that it was going to need a new engine. I took her the dealership rental back and she sent me to enterprise for a 45 day rental. They have had the car for just over two weeks at John Watson Chevrolet in Ogden Utah.

POWER TRAIN, SERVICE BRAKES
Valve body failed in Dec. 2024 and they replaced it. Valve body failed again in April 2025, they replaced it with new. Valve body failed again in Oct 2025, they said they will not replace it. The brakes locked up for a few seconds making a loud noise, it would not go in reverse which i showed the mechanic all three times, and it would not go over 35mph. they told me the new transmission they put in it in April of 2025, was not warrantied. This has been an on going issue since the original recall, and they refuse to fix it correctly. You will see from the documents, it has been in the shop 6 times in 10 months. now it sits in my yard because I don't want to get in a accident if it goes out while I'm driving. I can not go south for the winter like we usually do because of the truck. Chevy doesn't seem to want to fix the on going issue which was a recall.

ELECTRICAL SYSTEM
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 are date showing no sound. I have multiple videos but I am unable to upload due to size. I was able to share them with the service technician at Gentilini Cherolet. 500 John S. Penn Blvd. Woodbine, NJ 08270. Phone Number 609-459-0014.

EXTERIOR LIGHTING, POWER TRAIN
The vehicle was purchased new from the dealer in June of 2022. Since the purchase the vehicle has had multiple issues that are safety concerns. The backup camera cuts out on average 1 out of every 10 times the vehicle is placed in reverse always in low light situations like parking garages, night time driving or overcast/rainy weather. The vehicle has been in to GM on multiple occassions to have issue diagnosed and is still not repaired and TSB states for dealerships not to do more work to fix as this is a computer program issue and not a component issue, nonetheless the camera is still not functioning. The second area of failure is the transmission shift module. This module determines when the vehicle has been shifted out of park into R, N or D. The module has been replaced 2 times in 55,000 miles. When the module goes bad the vehicle gives a warning that the ability to shift will be lost. Finally the last safety issue that has been largely reported is the failure of the Telematics Onstar Module which runs the onboard communications for Onstar, Maps, GPS, and other systems that use the GPS signal. This means that any hands free technology tied to these systems no longer work leading to legal issues in most states that have hands free requirements. GM is charging around $1,000 to replace the Onstar module and it is taking 6 months or longer to even access the part if at all. Vehicle has also had running light/headlight, indicator light go out with no way to change a bulb, This requires an entire LED assembly, this issue is intermittent and may reset after the vehicle has been fully powered down, but creates a safety issue while driving with lights and blinker being in operable.
