2018 CHEVROLET SILVERADO 1500 Complaints

The transmission has been shifting hard. I have had it serviced to try and address the issue. It continued to shift hard, until suddenly slamming me down and locking me into first gear. It would not shift from first gear until I found a parking lot, placed it in park, shut the truck off and restarted it. This caused me to nearly rear end the vehicle in front of me. This has not been reproduced to date because the shop cannot get to my truck for 4 weeks and I cannot be without a vehicle for that long (won’t schedule and let me bring in the day before). There has not been an inspection done by anyone because I was able to avoid the collision, and the shop is too far out time wise. There were no prior indications/lights to warn me of a severe problem. The dealership informed me that this has been an ongoing problem with the valve body inside the transmission, but there is no warranty or recall for it. They were sure happy to take my money without telling me of the problems when I bought my truck.

I purchased my truck in December 2018 which is a 2018 Chevrolet Silverado 1500 4x4 crew cab automatic from Servco Chevrolet Dealership in Waipahu, Hawaii and making monthly payments for my truck February of 2019 truck runs good and purchased the warranty also had my oil and service changed when time is due which I always kept up. [XXX] and mileage was 40k while leaving work to go home at a stop light was red once turned green I pushed pedal to go and truck just changed noise tone started to run like rough idle, loud tapping noise coming from the engine, shaking and check engine light came on almost causing me to get into an accident. I pulled on the side and checked what was going on and heard the tapping noise from the motor. So I made an appointment with service department with Servco Chevrolet Dealership where i bought my truck from and spoke with the service tech for my truck to go in for repairs due to issue. It took 2 to 3 weeks for repairs to be complete and service tech informed me that I'm not the only person to have that issue which had to do with the lifters and camshaft with these motors but GM never came out with any recalls due to how much people has the same motors with the same issue. So luckily it was still covered under warranty but said the problem might come back and would just replace the faulty lifters and camshaft. So in August of 2023 my truck has the same issue but wasn't covered under warranty anymore and mileage is 61k and missed the warranty repairs that was for the lifters which I got it scanned cause check engine light and same issue and code was P0016. So I called Servco Chevrolet dealership in waipahu again and spoke with the service technician which he told me I just missed the coverage of the warranty repair and only way to get it fixed I would have to bring it back for them to scan and roughly would range from 4k to 8k to get it fixed. So my truck is parked in my garage and hasn't been moved but paying for truck. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

10 miles from home on [XXX] after Thanksgiving with my children sleeping at [XXX] in snowy cold weather, my engine began to fail. Power was limited on hills and the check engine light would come on and go back off when on flat or downhill. The next morning I took my truck to the dealer that I purchased it from where I was told the lifters had failed and I need a new engine. 1000 miles after I replaced my engine my transmission failed completely requiring a transmission replacement. Immediately upon picking up the vehicle and going down a long hill in the area, engine breaking turned on as expected but as the truck tried to slow itself, after 2 or 3 downshifts, the transmission began making a loud grinding sound and while still going close to 50 MPH, the speedometer showed 10-15 MPH and the tach dropped to idle. The transmission was decoupled from the motor. When gas was reapplied it seemed to make the connection again and resume normal driving. I called the dealership whose techs did not believe me and told me that I could 'turn off' the engine breaking feature. The situation continued to worsen each drive and it would do it more often. This was unacceptable and they finally had a tech ride with me to experience it and immediately agreed there was an issue and reordered another transmission. The third transmission did not fix the issue and was experienced immediately. They are now guessing how to fix the issue telling me I have to replace the transfer case out of my pocket with no diagnosis, not sure what is causing it and have not fixed the problem. Videos would not fit in upload due to size. Videos show speedometer failure. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2018 Chevrolet Silverado with a 6.2 engine suffered a Connecting Rod Bearing failure causing the engine to seize/lock up. The engine components are available for inspection. The engine seized/locked up and could have caused a crash. The vehicle is at my mechanics shop right now and will remain there until it is repaired. The vehicle has been inspected by my mechanic but no one else. The engine had developed a "tick" at idle and while driving. My mechanic found a bent pushrod in the engine and then found the engine suffered a camshaft lifter failure. He replaced all the pushrods, camshaft lifters, and the camshaft. It had been repaired and had been driven for a test drive. There were no warnings the engine was going to to fail. The engine just locked up without warning. The engine was removed from the pickup and was then disassembled and found to have had a connecting rod bearing failure on cylinder 7 and cylinder 8.
