The left front turn signal becomes inoperable at times. The foreword collision indicator warning will come on unprovoked at times. Both conditions correct when you cycle the ignition switch. I consider the turn signal problem a safety issue because it happens with no warning and oncoming traffic may not know I am turning left or changing lanes. When the foreword indicator appears, I doubt the system is operable.

Engine stopped while driving. Truck made dinging noise. Dash had no warning lights. Dash said need to press start button to turn on. Truck went into neutral by itself. Was able to pull over and put it in park. Tried to push the start button and nothing. Dealership said it needs a new motor. The truck has less than 10k miles. The motor has already been replaced once before at 4070 miles.

Upon purchasing a used 2023 Silverado, on the first night of ownership, I found the headlight on the passenger side to be defective. The high beams activated approximately a full second slower than the driver's side. It took me a few days to confirm what I was seeing, where I immediately reached out to help from the Chevy dealership it was purchased from. After back and forth, the dealership refused to fix this saftey item as it was "still operational just not 100%" or something to that affect (not a direct quote). The extended warranty company doesn't typically cover headlight housing. The dealership locally says both headlights need replacement. Chevy Corp is involved, under claim 104164057. I've brought to their attention that I have found several reports of this defect online for similar vehicles and model year. My contention is that, particularly due to being the passenger side, this malfunction could lead to accidents and collisions due to distraction of troubleshooting, and the delay of lighting on the side where animals and night hazards typically come from. I've read online reports of these headlights may take up to 3 seconds between sides to both activate, with one side running slower than the other, and eventual failure where the switching mechanism will get stuck. A Chevy dealer confirmed the defect and recommended replacement of both headlights, at my cost, for approximately $4000. Chevy is still investigating and trying to find a conclusion with the dealership, but I contest that I have malfunctioning saftey equipment that could lead to harm or injury, and at the moment, both dealer and manufacturer have been unwilling to resolve the issue. The failure occurs both in auto-headlight and manual modes.

A valve on the 3.0L Duramax is allegedly sticking, causing the vehicle to go into limp mode or be inoperable. This is a known issue for GM and they have issued a service bulletin on it. Unfortunately, no dealers want to address the issue and now we are left with a vehicle that if we do not pay to repair, after it being ours for only 5 days, the vehicle will be unusable. This vehicle is under warranty still and this part is needed for operation. I believe this avoidance of a recall is harming customers and creating pay to drive schemes. This needs to be addressed before thousands of customers begin paying for a repair that GM knows is their fault.

MOMENTARY WHEEL LOCK UP. ENGINE WARNING LIGHT CAME ON. Safety warning not to drive as could cause catastrophic damage to transmission. Same symptoms as noted on update GM bulletin N242454441. 12/24. Only extends warranty 2020- 2022 models up to 150,000 miles. Gen 3 Transmission Control Valve appears to be the fix... My vin not included in the extended mileage. I just turned 62,000. Just out of Standard Warranty.
