They said it was just the latch button . So they fixed it they said and still my blinker lights would just come on and then I hit a deer and my seatbelt did not latch and my airbags didn't deploy even though my app says they did.

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

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 th

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.
