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.

ENGINE
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.

ENGINE, POWER TRAIN, UNKNOWN OR OTHER
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.

FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP, ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR
The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at 70 MPH, the vehicle was losing motive power with the “Engine Power Reduced” message displayed. The temperature gauge indicated that the engine was overheating. The contact initially had the vehicle towed to the dealer and diagnosed with a defective fuel pump. The dealer replaced the fuel pump, the fuel pump system, and the fuel pump sensor; however, each repair failed to fix the failure. The contact towed the vehicle to AutoNation Chevrolet Pembroke Pines (8600 Pines Blvd, Pembroke Pines, FL 33024) where the vehicle was diagnosed with a defective catalytic converter; however, the part remained on back order. The manufacturer was notified of the failure and a claim was filed. The vehicle remained in the possession of the dealer unrepaired. The failure mileage was approximately 15,000.

ENGINE, POWER TRAIN
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!

ENGINE
Speed limit 70mph and driving on the highway, suddenly the vehicle began to shake and the engine light came on and the vehicle was making a forced deceleration to 40mph. Other vehicles had to swerve to avoid my vehicle, as I was attempting to pull off the highway safely. "service brake system" alarm also came on. The manual advised when getting this alarm to have the vehicle towed. Once at the dealership this note was on my service papers " Customer stated engine light was on and truck running rough and shaking, review of DTC's showed cylinder misfire on #3, tested showed possible issue with spark plug. Relocated coil to different cylinder to see if issue followed. Misfire still noted on cylinder 3, replaced spark plug and conducted test drive and note misfire still present on #3. Removed valve cover and noted failed lifter on intake valve for cylinder #3. All lifters replaced on left side of engine." The dealership stated that "this is a known problem for the 5.3L V8Ecotec engine, that the lifters FAIL." I am a female, I was traveling alone and had to find tow service and pay up front. Once transported 20miles to the nearest dealership, on a Saturday afternoon, I was stranded at a hotel for 2 days waiting for the dealership to open and check out the vehicle. If this is a "known" problem with this engine, THEY SHOULD BE RECALLED. Now I get to worry when the other side of the engine's lifters will 'fail' so they can be replaced under warranty. This is unacceptable in an almost new 2021 truck with 20,000 miles on it.

Vehicle engine has experienced engine lifter failure at 28,000 miles. Engine began shaking violently, check engine lights flashing, traction control light, and stability control lights all came one while driving on the highway several hours away from home.

ENGINE, POWER TRAIN
The 2021 silverado v8 randomly started making a knocking noise. The steering wheel would shake randomly as I accelerated and stayed above certain speeds. I’m barely able to drive slowly residential speeds at most. If I drive any faster I’m worried for my safety that the car while break down in the middle of a busy road posing a danger to my family and those around me. I’m not sure if this is a lifter issue, or engine issue but it seems to be a widespread issue that I haven’t recurved any recall notice for.

STEERING, SERVICE BRAKES
2021 Silverado Trail Boss. Went to the store, came outside started the truck and it showed me ESC Warning and Power Steering Failure Drive with Care notice on the dash. The Steering was very hard to turn. I tried multiple times, and it did not work. I started reading information on line and found out that there are multiple truck owners who had same issue. I saw some information to leave the truck off for 20 - 30 min and try again. I left it off for 30 min and started again. At that time it started fine. I am going to the Chevy dealer because this can also happen while I am driving and it can cause an accident. My truck has only 12k miles.

FUEL/PROPULSION SYSTEM
Check engine light came on followed almost immediately with an Onstar warning to service the engine and transmission within 7 days. Took truck to dealer. They diagnosed problem was fuel system contamination. Hole was found on the inner mesh liner of the fuel filter which allowed water and a sludge like material to get into the fuel system.

ENGINE AND ENGINE COOLING:ENGINE:HARD PARTS INTERNAL/MECHANICAL
While driving down the road the engine began to run erratically and several seemingly random errors appeared relating to the parking brake, windshield washer fluid, and engine. The vehicle began shaking violently until stalling out on the road. After bringing the truck to the dealer and waiting for weeks to have it returned I was notified that there had been a lifter failure. Vehicle mileage had been at 12,600 miles at this point.

ENGINE
Truck started having a rough idle and was popping and banging while driving. It was hesitating while driving in traffic and would slowdown and jerk while trying to drive to the dealership. It stalled at red lights multiple times. Once it got to a dealership and they identified it as #4 cylinder lifter was malfunctioning. They have not yet disassembled the engine yet to find out the extent of the damage. This is a known issue with these trucks and GM won’t issue a recall to proactively fix the issue before more damage is done to the motor. Some of which may not show up until after the warranty expires. There was no warning light or check engine light on at anytime. The dealership service department was very surprised by this. Now I’m without my truck for at least 2 weeks with no loaner of voucher for a rental. The truck has less than 19,000 miles on it and has had all regular maintenance done at a dealership.

"no start" issue. Intermittent no start increased in it's frequency until it wouldn't back in July 2021, it had approx. 9600 miles on it. Had it towed to dealership. They could not recreate problem. I raised hell, and started reading that others had similar problem. A TSB came out that advised tech to install .5 shim. That seemed to have worked until recently late May 2022, have appt. with dealership again. They didn't do a scan the next day to pull a code since one might have shown up at that point. Most likely nothing there now. truck has been driven an additional 10K miles since initial problem and now shows 21400 miles. I can't have this problem every 10K, since soon this will be coming out of my pocket. and it needs a fix as others are having the same problem. GM has had well over a year to sort this out so I'm hoping if it isn't the cam sensor it's something else fairly straight forward. Heading in for service again on 6/15/2022 for same complaint.

ENGINE
I was driving and noticed several loud clunking noises coming from the Engine bay. The truck began to cut out, shake, and misfire. My dash began to flash and state I had a parking brake failure. I had no choice but to be towed. I have just shy of 17,000 miles. The dealership stated I had two lifter and 1 rod failure. They replaced the rod and all lifters on one side of the engine. I took the truck home for one night and it broke down again. The dealership stated it was fixed for a second time. When I picked it up again, I made it 1 mile down the road before the truck had the exact same symptoms with shuddering and misfiring. It is at the dealership for a third time. I was surprised to fin several class action lawsuits now filed against gm concerning the lifter issue. YouTube is full of lifter issue videos. This should be fully investigated and obviously warrants a recall for lifters, rods, and the camshaft.
