| Jul 2022 | ENGINE AND ENGINE COOLING | 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. | Crash: No Fire: No | Unknown |
| Jun 2022 | 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. | Crash: No Fire: No | Unknown |
| Jun 2022 | ENGINE | The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving approximately 10 MPH, there was an engine misfire and then a knocking sound started coming from the engine. There were no warning lights illuminated. The contact had the vehicle towed to the dealer who stated that there might be a failure with the valve lifters; however, a diagnostic test had not been performed. The vehicle had not been repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 40,000. | Crash: No Fire: No | 40,000 |
| Jun 2022 | ENGINE | "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. | Crash: No Fire: No | Unknown |
| Jun 2022 | ELECTRICAL SYSTEM | 2021 Chevy Silverado durmax brought it in three times now for starting issues 2nd time found data module was bad two weeks later brought it back for same issues. Dealer said they can’t find anything wrong I’ve broke down on hwy 5 in. Dangerous spot and know I don’t feel safe driving this. | Crash: No Fire: No | Unknown |
| Jun 2022 | ELECTRICAL SYSTEM,SERVICE BRAKES | Can't pull a trailer without the SERVICE TRAILER BRAKE SYSTEM LIGHT coming on a dinging over and over. Had my trailer completely rewired only to find out its a malfunction on my truck not my trailer. My truck is a 2021 Silverado z71 trail boss with low mileage | Crash: No Fire: No | Unknown |
| May 2022 | ENGINE AND ENGINE COOLING | The contact owned a 2021 Chevrolet Silverado 1500. The contact stated that approximately 35 minutes after parking and turning the vehicle off he was notified that the vehicle had caught on fire. The fire department was called to the scene and extinguished the flames. Upon inspection, it was determined that the fire originated in the engine compartment. A police and fire report was taken at the scene and the vehicle was towed away. During the incident, the vehicle was destroyed. The manufacturer and local dealer were notified of the incident. The failure mileage was 12,000. | Crash: No Fire: Yes Towed | 12,000 |
| May 2022 | 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. | Crash: No Fire: No | Unknown |
| May 2022 | SERVICE BRAKES | When I start my Chevy Silverado 1500, three warning lights come on that are telling me that I have brake system failure 43 MPH top speed, Service ESC and Service Trailer Brake system. When I drive, the brakes are very mushy and the truck is very difficult to brake. 20 minutes later after stopping and getting ready to take the truck to the dealer, the brakes worked fine. The dealer couldn't replicate the problem at first, but finally had the issue when they were putting it on the rack to perform improve my tire alignment, so they said they updated the software. The truck brakes worked fine when I left the dealership. The next day (Saturday) I went to start the truck and the same issue happened. I can't take it in as Service is not available on Saturdays so I started looking online. Apparently there are several other owners dealing with this same issue and have been for years. I have read that it might be a variety of things causing this issue, but someone needs to get this resolved ASAP as I have read about some getting into accidents regarding this. My truck is only 16 months old and only has 14,000 miles on it. | Crash: No Fire: No | Unknown |
| May 2022 | UNKNOWN OR OTHER | My 2021 Chevrolet Silverado started on fire and blew up in my driveway. I had just returned from the store, parked it and went inside. No more than 3 minutes later, my neighbor came running over to tell me my truck was on fire. There were no issues at all while I was driving the vehicle. The township fire department said this is the 4th 2021 Chevrolet Silverado that has burst into flames in the last 6 weeks. They said they all had the 2.7L Turbo engine, as well. The truck is a complete loss. I have contacted the dealership and Chevrolet about the issue and have not heard back yet. The fire started in the engine compartment and quickly raged out of control. The hood and engine disintegrated from the heat. The vehicle was towed away and the insurance adjuster has yet to go out and look at it. If I would've been stuck in traffic on the way home, I would have been in the vehicle and may not be here typing this report right now. It went up that fast. This is a major safety issue that needs to be thoroughly investigated before somebody loses their life. It nearly caught my house on fire, but thankfully there was only minor damage to some garage trim and the driveway is ruined. Please investigate this issue immediately. This was a pretty traumatic experience, to say the least. | Crash: No Fire: Yes | Unknown |
| May 2022 | UNKNOWN OR OTHER,ENGINE | On April 29, 2022 between 4:45 - 5:00 pm Eastern, I was dropping off my son at work when I suddenly experienced a variety of Truck Diagnostic Error messages on the front driver display window.

At that moment the truck experience a cut in power and slowed down with a knocking sound coming from what seemed under the truck. I slowly proceeded to drop off my son and drove back home and parked the truck. Truck was towed to local Chevy dealer on Friday of that day. A preliminary diagnosis was done Saturday, April 30 suggesting an Engine Lifter issue. On Monday, May 2, 2022, a final diagnosis determined engine lifter failure on one side of engine bank.

| Mar 2022 | FUEL/PROPULSION SYSTEM | A squirrel chewed into the fuel line [Hose - GM (84871298), see: https://www.gmpartsdirect.com/oem-parts/gm-hose-84871298). This caused a fuel leak that could be directly observed only while the vehicle was running. On one occasion, however, a small pool of fuel appeared under the vehicle immediately after shut off. This part failure poses a fire and explosion risk. In addition, the wasted gasoline pollutes the atmosphere. The line was replaced at Lynn Layton Chevrolet of Decatur Alabama (invoice 608119). The part was inspected by Lynn Layton Chevrolet as part of that service ticket in order to determine the cause of the leak. To my knowledge, further inspection has not occurred. No warning lamps indicated the failure. The problem was detected by observing the trail of fuel when parking. | Crash: No Fire: No | Unknown |

Correction: Removed intake, exhaust manifold, value cover, cylinder head, right side replaced all lifters, one push rod, related gaskets, reassembled engine. | Crash: No Fire: No | Unknown |
| Feb 2022 | ENGINE | While driving East on I-24 with my granddaughter. I felt a thump much like hitting a big dog or something in the road. I looked at my 10 year old granddaughter, she was looking at me, she said what was that? I said I don't know, but it happened again in about 1/4 mile down the road. We traveled about another 1/4 mile when the truck started sounding like a machine gun being fired!! My granddaughter started crying as she was scared, I pulled over into the emergency pull off to check my truck. It was running good now and NO ENGINE LIGHT was on. So I continued driving toward Clarksville, TN. although I considered turning back and heading home. I thought maybe it was water in the gas or something. After arriving in Clarksville to pick up my two grandsons we started home. As soon as I got on I-24 west the truck started the same thing again. Felt like we hit a big dog and then started sounding like a machine gun being fired. This time the ENGINE LIGHT DID come on. I was afraid the truck was going to quit running and there I was with 3 grandkids on a very busy I-24!! I contacted Patroit Chevrolet where I purchased the truck at. They told me it would be 6 weeks before they could look at my truck!!!! I hung up but called back as I was afraid that I couldn't make it home, the truck was running bad!! They found that it had dropped a lifter, it had only about 6,300 miles on it!!! They had it for about 3 weeks. Now, I find out that GM has had a lot of problems with these motors, "A LOT of PROBLEMS"!! I,m sure the problem WILL happen again, I am hoping no one gets killed when it does. THIS IS A DANGEROUS PROBLEM!!! GM needs to replace these motors or buy them back or something!!! | Crash: No Fire: No | Unknown |
| Jan 2022 | POWER TRAIN | There is a massive shudder that sounds like the whole dash could come loose. feels and sounds like rumble strips and off road driving mixed all together. It happens at all speeds and when rpms are steady around 1200-1400. | Crash: No Fire: No | Unknown |
| Jan 2022 | POWER TRAIN,ENGINE | I have a 2021 Silverado 6.2 being repaired for failed lifters. I see this is a common trend and can cause hazards when pulling over for a faulty motor. 10 speed Transmission downshifts from 2 to 1 harsh with rpms jumping up causing for me to apply more brake pressure to stop. I have had a few incidents when I get close to the vehicle in front coming to a stop. I have taken vehicle to dealer for issue and they couldn’t replicate issues. Check engine light has popped up once or twice but never stayed on long enough to throw a code. | Crash: No Fire: No | Unknown |
| Jan 2022 | SUSPENSION,POWER TRAIN,ENGINE | Engine valve lifter failure at 20,000 miles; engine hesitation and power loss. Error to parking brake and to electronic stability control.

The truck is driving rough. | Crash: No Fire: No | Unknown |
| Dec 2021 | SERVICE BRAKES | While driving the vehicle on a snow covered road the check engine light, abs light, esc light and parking brake light all came on. The vehicle also lost braking power. Took to the dealer. They told me it was a brake control module. If you do some research this is a on going thing since 2018. But they still continue to put this part in the trucks. On top of all of that they don't have a replacement part for the truck. Now the truck is going to sit at the dealer for one to two months. I am now paying on a truck that I can't drive to work and no loaners available. my question is why are they aloud to still put these parts in a truck. How do I know if they fix it if the problem wont happen again. If it does happen i hope my family and any one else is not in the way of my truck that I am unable to stop. | Crash: No Fire: No | Unknown |
