During acceleration my vehicle had a whinning noise coming from near the transmission. It will buck and then when slowing down to a stop it bucks like being hit in the rear by another vehicle. It also shudders and makes the reduce engine power light come on.

- Jaffrey, NH, USA

Bought my truck with 29,000 miles on it. Was making a noise in rear tire. Took it in and it was the break calilper. Dealership wanted $1500 to replace it a week after I bought it. Stated that it was not covered. After a week of arguing, they did not charge me for it. Around 40,000 miles, every once in a while, it would feel like I was being rear ended when I came to a stop. It was not often, but around 55,000 miles, was more frequent. I took it to the dealershp at 62,000 miles and they said that it was a torque converter and would not be covered. Fixed it at a shop $2700. Lifter and Cam in the UP of michigan $5000. Oil lines at 110,000 $700. Torque converter again at 130000, and now lifter and camshaft again at 145,000 miles. I feel that GM should back their product. I had a 95 Chevy Silverado that I sold with 360,000 miles and never had any issues except fot transmission at 250,000 which is expected. I have all receipts showing proof

I have a 2019 Chevrolet Silverado 1500 LTZ. 5.3 Ecotrac 8 transmission with 89,000 miles. I bought it used and have had it 12 months, but only drove it 9 before it malfunctioned causing severe electrical & mechanical problems. I was driving the truck when the EPB, service engine, stabilitrac, ECBM warning lights came on, also driving over 43 miles an hour could cause a crash due brake failure This caused the emissions. transmission, & throttle to shut down Truck would not shift out of low gear. It would shift to park but did not recognize it was in park which kept the accessory on running down the battery, the tail gate would not open, and the information system shut down. I got sick and was in the hospital for 5 weeks, the truck was vandalized. The body repair shop took it to the chevrolet dealership in long beach to have it inspected. I did not tell them the vehicle had malfunctioned, throwing code U0101 and another code. I wanted the dealer to find the problem, the truck had not been driven since it was parked from the malfunction. All they came back with was I had a burnt cylinder and would be 9000 to fix due to maintenance, we maintained this truck changing the oil every 3000 miles with Castoroil synthetic oil, regularly checking and maintaining transmission, brake, all-fluids. Supposedly they ran a diagnostic, if they did they would have found these warnings and that main code U0101 would have showed up. When it happened Onstar ran the diagnostic and told me to take it immediately to a dealership. That dash should have lit up like a christmas tree that-??s how many light were going off. The dealership never said a thing about these lights. Now i-??ve read where Chevy had a problem with the EPB and only put them on this model from 2019 to 2022 because of this. I found on other sites recalls that included what happened to my truck, but not in your web sight. There was major design and manufacturing flaw with this model and year. I-??ve read complaints on this.

On [XXX] I was driving in Beloit WI. Luckily I was in town and only doing 30-35mph and not another mile because I was headed for the interstate and we all would have died, because all of the sudden my parking brake locked on, my check engine light, ABS light, traction control light all came on and gray smoke just started pouring out my exhaust. Had it towed to my usual mechanic, it had 38 different codes on it, he worked on it for 8 hours and said it needed to go to a dealership. Towed it to a dealership, lifter on cylinder 5 went out and I was told "Yes camshaft is destroyed on that cylinder.. just need one. But tech would pull engine out and pull apart-?? or replace engine as does not include the fact that oil pump the timing chain the timing chain tensioner, the rod bearing the main bearings, and most importantly the camshaft bearings are still gonna be old and original to your engine. If you replaced just a camshaft. So later on down the road, something there could fail and more than likely the oil pump but again it-??s just more money and more what else but if you are going to commit to that then you probably should commit to timing, chain, and oil pump, and everything else in which case now you start adding all the prices of that components in with labor on top of it, and an engine in my opinion would probably be better" and the engine comes with 100k mile warranty.
