ESC failed. The 2021 Chevy Silverado (39495 mi) began to shutter and a slight bouncing of the rear end. The ESC light came on the service ESC warning on the dashboard then the check engine light began to blink at the same time the parking brake light came on. The dash warning switched to have parking brake serviced. The truck as best as I could tell applied the parking brake several times for no reason while at highway speeds and traffic on all sides. All warnings stopped when Auto engine shut down at exit ramp light. Previously brought into dealership for -??Service ECS-?? and -??Service Power Steering Drive With Care-??. I was told -?? unable to replicate -?? (23194 mi). Vehicle was returned to me. They did confirm the dash warning was stored in the computer. I do not believe any warning (blinkers) or brake lights came on to warn vehicles behind me of the rear brakes being applied by the ESC.

On 12/26/22 my wife noticed a noise coming from the engine of the pick up truck. On 12/27/22 I started the truck and noticed a noise coming from the engine. I lifted the hood to try and locate where the noise was coming from but I could not see anything. There were no lights on the dash. I drove to work and parked it. 8 hours later I started the truck back up and the noise was still there. I began driving home and the truck made a spurted noise causing me to jerk the wheel nearly driving off the roadway. The truck is still making the noise. I contacted the Chevy dealer and they explained they would take a look into the issue. I-??ve done some research and noticed that a bunch of 2020-2022 Silverado-??s have been having lifter issues. I-??ve also seen that the dealers are only replacing one side of the lifter banks and the others are failing 500-2000 miles after the repairs. I-??ve also seen that people-??s trucks have failed on highways and streets causing accidents and or traffic hazards. This is something Chevy needs to look into and fix to prevent any serious injury or death created by these issues. I don-??t have photos but I do have a video of the noise that I could email if need be since I can not attach the video to this form.

Lifter failure

Anytime the weather gets colder than 32degrees Fahrenheit the DEF system freezes, which even if the tank is full makes the truck go into limp mode until it thaws out. The engine light pops on and off with no codes associated with it. Now the breaks and break lines are freezing when it gets below freezing. These are just a few of the reoccurring problems we-??ve experienced since buying the truck less than a year ago.

Vehicle will not start and cranks until starter kicks out, about 30 seconds each time. I am afraid if this happens at a traffic signal or stop sign it could be bad. I took it to the dealer on July 30-2022. (2972 mileage) and they could not verify concern. I found a safety bulletin on a GM website for a extended crank/ no start. It is PIP5806D, The dealer says they know nothing about this. It lists a labor operation number 4088148, due to a corrupt signal from camshaft position sensor to the ECM. It has happened now 4 times, and current mileage is 6973. I have been dealing with Champion Chevrolet in Reno NV. It has started after 8 to 10 crank time outs and the battery starts slowing the crank speed down, but around 10 to 15 minutes have passed by then.

Engine oil cooler defect was diagnosed by chevrolet dealership. Everytime I drive the truck, it would leak oil and would have a burning smell all underneath the truck. The part was on backorder for over a month and a half. After this long wait of not being able to drive the truck, the dealership finally put a new oil cooler in. The problem persists and they are not able to figure out from the engineer what will solve the problem. I have been out of a truck for over a month and a half now with no hopes of the issue being resolved.

Per the repairing dealership, a lifter went bad. GM will not replace all of the lifters, just one side of the engine, due to the vehicle having over 8000 miles. Mine currently has 12,500. I no longer feel safe knowing that GM is replacing only half of the know defect with new parts that have the same issue (Told to me by the repair facility.) The vehicles engine could fail again, resulting in loss of acceleration. No warning was observed during, however after the fact, check engine and other warning lights were illuminated.

Engine misfire due to faulty valves which caused vehicle to lose power and stall. Check engine light began to flash on dash. Took directly to Chevrolet dealership. Dealership confirmed faulty valves and bent pushrod on left side of engine. Dealership to repair engine under warranty. Dealership stated that right side engine valves had already been replaced in November 2021 at approximately 13,000 miles. This was before I purchased the truck in May 2022 and I was not made aware of this repair. Truck now has 22,900 miles. Dealership stated that this is a known issue with Chevrolet 5.3 liter engine and they preform similar valve replacements on this engine at least once a week.

2021 Silverado RST, 5.3. Started having strange loud random clicking sounds when first starting. Would loose power, at take off or when trying to accelerate. This was at 9400 miles on the vehicle. Was not showing any check engine light or issues on dash. When examining engine compartment, found loose bolts, that had broken. Took it to local Chevy dealership, acted like there was nothing wrong with it. Instantly trying to get out of performing work. I had a feel it was going to be lifter issues. Found out while there around 4 thousand miles it already had lifters replaced. After debating with them for two days, and trying to convince them there was issues. They finally found multiple problems with lifters, misfiring, rocker arm not moving due to collapsed lifter. They found broken bolts in cylinder heads. Ended up having to replace all left and right side lifters.
