1 and 7 lifter failure occurred. Truck failed while driving on a congested highway putting myself and others at risk when speed was speed was reduced and truck eventually stalled. Truck was serviced by local dealer and confirmed lifter failure. KNOWN ISSUE!!! NO WARNING PRIOR TO MALFUNCTION.
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 -€œService ECS-€ and -€œService Power Steering Drive With Care-€. I was told -€œ unable to replicate -€œ (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.
The 2021 LT Trail Boss with the 5.3L engine started a really rough idle, engine knocking, random misfiring, had Service Emergency Brake, Service ESC messages on the display, check engine light and several other dash warning lights. The dealer diagnosed the truck with lifter fail apart (failure), intake valve push rod bent, and PCM failure. Odometer reading 19,368 miles.
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.

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.
My truck has had lifter issues twice now. Finally, a new engine had to be installed and I have recently began getting the check engine light along with sputtering sensation while the truck is on idle. Also, I purchased this truck, brand new, and I was without it for close to six months.
I have a 2021 Chevy Silverado. The #3 Cylinder has failed and an all new lifter kit needs to be installed. Truck was knocking violently and died. Dealership stated the parts on back order nationwide and they have no clue when replacement parts will arrive.
At 7,316 miles my 2021 Silverado 5.3 V8 had lifter failure while driving, the truck would not accelerate correctly and I was forced to pull off the road, luckily it was able to turn off at the next road before the vehicles behind me caught up. The check engine light was blinking and was making a lot of popping noises. I was able to take back roads and drop it off at the dealership for repairs.
This 2021Chevrolet Silverado 1500 LT Trail Boss I purchased new April 2021. Since I have owned it the check engine light would flash randomly with or without a load and now just this past weekend (7/17/2021) the check engine light stayed on. Took it to the Chevy dealer for repair and was told it was a lifter problem. I recently just purchased a camper, well under GM allowed towing capacity, and worried that if the engine should fail either up hill or down hill that there could be loss of control of vehicle from other systems shutting down.
Vehicle began having issues at 3 months old... Random service messages, defective headlight, wierd engine noises at startup and stalling upon acceleration/deceleration. I took it to the dealer several times about the issues I were having but they always say they aren't able to replicate any issues. 3 months later I was driving on the highway and the engine started knocking. Had it towed to the dealer and it took them 6 months to replace engine, tcm, starter, and other parts. After finally getting the truck back, it was still stalling and there was a check engine light... Dealer did not reassemble the vehicle properly and several parts and bolts were still missing. It went right back in the shop and catalytic converters were replaced. I also mentioned missing parts and bolts. I get the truck back again and it still seems like it wants to stall. I was turning into a parking lot a few days later and it seemed like it wanted to cut off. While I was distracted trying to see if the truck cut off, I hit a small pole... Truck was damaged way more than it should have been because the dealer did not reassemble it properly. Body shop said my bumper was only held on by 2 bolts and several other bolts and pieces were missing. They said if my bumper was attached properly the damage would not have been as bad. The vehicle was already unsafe because of stalling and the dealer made it structurally unsafe as well... I have opened cases with gm and they aren't doing anything about it. Here this truck is 14 months old and it's been in their possession more than mine... I have asked them about replacing the vehicle and they insist on fixing the issues but never do and I end up driving an u safe vehicle around.
Add 1 more victim to the ongoing and growing list of GM owners of vehicles with 5.3/6.2Lmotors with DFM lifter failure. 50 miles after returning from a 500 mile trip from N. Wisconsin fishing trip this motor threw in the towel. Dealer assessment cylinder #6 lifter failure with an extra bonus of damage bad enough to require replacement of entire cylinder head! This motor has 11K. miles on it, and I have had oil changed multiple times as I am old school and don't buy into the whole 7500K. thing. Guess I should have saved my cash for something more fun! Check engine light did not come on till almost 2mi. after vehicle started running badly, flashing check engine light did not come on till I was almost home 15 mi. Had it towed to the dealer on my own dime!
