Started my truck and the check engine light was flashing along with a few other warming lamp lit up. When I went to drive the truck the engine started to make some noise, and didn't have much power. After being diagnosed by the dealer ship the motor needed new valves, lifters and camshaft. The bill for the repairs is going to be around $8,500 and GM is not willing to help with the costs.
Total catastrophic engine failure. Occurred at roughly 80,000 miles. Engine bearing shattered causing total engine loss. Needed to be replaced. Occurred in May 2023. There were no precursors to the event and the engine had been well maintained. I noticed an investigation of my vehicles engine and thought I should report this.
Major engine failure / main bearing failure with the engine burning oil and no warning signs no oil leaks or no burning oil smoke out of exhaust. I-??m in the process of having the engine re built out of pocket on this date 1/19/2025 and have no documentation from repair shop at this time so I can-??t up load any further information till I get it completed,
I was driving 65mph down the freeway when the truck suddenly turned off and the dash told me to put in neutral and start again so I did just that. Made it about another mile and the truck completely turned off and wouldn-??t turn back on there was nowhere to pull over or get off the freeway in that time frame so I was stopped in the middle of the highway with my family in the truck. Luckily a guy in another truck was able to push me over to the shoulder with his vehicle where I sat and waited four hours for a tow to the dealership. Two days later they called me and told me it-??s spun a bearing and threw two rods and needed a new engine. I-??m anal about servicing my vehicles they told me it just happens, but it was a brand new truck with only 35k miles. Ever since I got the new engine installed it-??s constantly squeaking and they can-??t seem to pin point the issues I feel like it-??s going to happen again and this next time I-??ll probably be out of warranty and it-??ll be out of pocket for me to fix.
The crankshaft bearings failed causing engine to knock very loudly. I didn't get an engine light. Dealership did replace one bearing and said lifters we fault and replaced. This happened with just over 33000 miles on truck. I didn't receive any extended warranty from manufacturers for any problems that may occur in future from pieces of metal or other contamination to inside of engine.

While driving down a major, extremely dangerous highway [XXX] in Pasco County, FL) my truck randomly shut off (with zero warning, no check engine lights, nothing) Thankfully, i was already in the right hand lane and managed to coast into a gas station. At 60, 375 miles on my 2021 truck I was 352 miles outside of the powertrain warranty, so I had my truck towed to the closest chevy dealership to see if they would good-will the warranty. They (Chevy) reported to me that there was a rod-knock with an estimate of $17,203.52 to rebuild the motor. I would also have to pay approximately $2000 (10 hrs of labor) for tear down of motor to even see if GM would POSSIBLY pay out anything on warranty. I am the only owner of this truck since day 1. I have every oil change record that was done as specified by the manufacturer. I have no means of transportation at this time. My truck is available for inspection. I am also unable to take out any other vehicle loans while I am forced to pay for a truck that now, has no motor. Also, I went in for a recall of a software update for the forward collision system. Previous to the dealerships update, the system was working fine. After the update, the collision system no longer works. This is greatly affecting my ability to work, and function as a member of society. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Vehicle has less than 35k miles. Vehicle started and operated normally Attempted to turn onto main thoroughfare from a stop. While still in drive, vehicle engine rev-??d up but transmission did not engage. Attempted to cycle through gear selector with same result. Reverse is the only gear that allowed vehicle movement. Serious safety concern if this were to happen while traveling at any significant speed or if trying to merge or cross heavy traffic. Vehicle has not had an official diagnosis, but I believe this is a transmission valve body problem known to the manufacturer. There was no indication prior to this event of any mechanical or electrical problems with the vehicle. This issue could easily get someone killed.
I bought my 2021 chevy silverado 1500 Lt crewcab in march 2021 it had 5000 miles on it I had it for 2 weeks when it started shaking and the engine light was flashing. Took it in to auto nation cheverolet and they had it for a month. when I got it back and started the vehicle the engine light was still flashing. They had to change the lifters on Bank 1 because number 8 cylinder lifter was bad. why didn't they change all the lifters. 3 years later I am having the same issues getting a misfire on number 4 cylinder truck shaking and white smoke coming out of the exhaust. Also the dash lights up with service parking break and service esc when the engine light flashed. ofcourse my warranty is exceeded and GM knows about this problem with the 5.3 and 6.2 engines and won't issue a recall. it is a big saftey issue as your vehile looses power or shuts off. this shou;dn't be happening especially when your vehicle is fairly new. this is twice now this is happened in 3 years and now I have to pay out of pocket to get this fixed because gm won't issue a recall on this known problem that is happening to thousands of customers.
The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the vehicle jerked with the oil pressure gauge fluctuating. No warning light was illuminated. The contact pulled over and upon inspection, the contact discovered that the engine oil was extremely low. The contact added six quarts of oil to the engine. The vehicle was taken to the dealer, but the cause of the failure could not be determined. The contact stated that the engine was consuming an excessive amount of engine oil, and that six quarts of oil was added every 5,000 miles. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 56,400.
While driving down the highway on 11/03/2024, the engine warning light started to flash, I heard a clicking & Clanging noise so I pulled over as soon as I could find a safe place. Turned the ignition off & on again & engine warning light did not come back on, but still heard noises coming from engine. When driving home, the engine warning light came on again. I stopped again & turned the ignition off. When I turned it on again, the warning light quit flashing. I drove to the local GM dealer the next day, and they said it was a lifter problem. I did some research and found there were many lifter problems for a 2021 Silverado that I owned. I was hoping the dealer would replace both sides of lifters as they told me there was an issue & they were reengineered. Service department employee said they could only replace one side as that was all GM would approve. I told the employee that I did some research & there was a bulletin that said if mileage was less than 16,000 miles, both sides should be replaced. The employee said you surely have more miles than that & I showed her my odometer reading of 14,528. Again the employee told me that was all that GM would approve. I believe this is a safety issue if there is not a safe place to pull over. Also there should be a recall to replace these lifters with the reengineered lifters or extended warranty so us consumers are not stuck with a huge bill in the future as GM is aware this is a chronic problem.
When I started my truck in the morning a group of warning lights came on. This included check engine, ECS control, Parking Brake service I took truck to dealer that said I had bad or broken lifter in cylinder # 6.
Lifter failure of the right bank in 2021 at 19,000 miles. At the time of failure engine was 2.5 quarts low on oil. Ever since, this truck has been using oil excessively. I am currently involved with an oil consumption test. Of which over the last 5k miles I have had to have more oil added by the dealership.
I took my car to the dealership four times because the engine light and the ESC light kept coming on. It kept saying there was a misfire so they changed the spark plugs and did a gas treatment after I left the dealership the light came back on so I returned the next day. They change one wire that-??s what they told me. The problem was so I left engine light came back on. I returned the next day then they changed the wires I left the facility again. The next day I got them started the car, the same problem, engine light, and the ESC light and now they have the car in the shop and they need to break the engine down to see what-??s causing the misfire and to find out if I need a new engine or not. Who is all that sh*t right now?
Multiple times at varying speeds my 2021 Silverado has produced engine misfire codes. I have never been able to get to it quick enough to see what cylinders are misfiring so it always gives me a general P0300 code. The following first two times it was confirmed by Widrick truck and diesel in Carthage, NY. The last time it happened, the code disappeared before I would take it to the Chevy dealership. Widrick said they can-??t fix the problem because they don-??t know what it is, and Chevrolet denies there is a problem at all. The truck still has less than 50k miles on
