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.

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.

ENGINE, UNKNOWN OR OTHER
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. In addition my OnStar advanced diagnostic alert system informed me with the following system issues: Engine and Transmission; StabiliTrak stability control; Antilock Brake; and Emissions. 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. Vehicle is still under Warranty with 17,400 miles on it.

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.

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!!!

ENGINE, POWER TRAIN
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.

The ESC, parking light, traction control, and engine light came on while driving home. The engine started to shake. There was an issue with braking and steering the vehicle that made it difficult to control. A message on the dash said Service ESC. A report was sent via OnStar Notifications that said An issue with the emissions system is detected. After trying to restart the vehicle a few times, the lights will not go away. The truck is driving rough.

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.

FUEL/PROPULSION SYSTEM
Starting smelling gas inside of the cab, at first thought it was non-issue, but the smell persisted. Several days passed, and when I went to warm up my truck in the morning smelled a strong gas odor, and when I looked under the engine - there was a pool of gas, and gas was leaking. Took it in to the dealership (thinking it was a simple loose filter line) but they now say that it is more than that. Not sure if this has been a re-occurring issue with these new trucks, but it could have been a very dangerous situation.
