What 346 owners told NHTSA about the 2023 Chevrolet Silverado 1500 Ltd

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.

Occasionally, from the time the vehicle is started to a while after shutdown the left front turn signal / DRL / parking light does not work. Upon turning on the left turn signal, the driver information center says check left front turn signal lamp. The rear turn signal flashes rapidly and the front doesn't illuminate. I've had the vehicle to the dealer 3 times and counting. Twice they confirmed the problem. Wires were inspected and a connection to the turn signal assembly was greased and researes. The next step is to replace the turn signal / headlight assembly.

While driving the Vehicle - the left turn signal stopped working. When dropping off at the dealership was informed it is a software issue. The issue went away for a couple of months and then the exact thing happened when using now the right turn signal. This provides no way of letting other people know who are headed towards my vehicle that i am turning lanes. The last incident was verified by the dealership. The headlight is not serviceable. No warnings occurred until after a few blinks where the front signals wouldn't work then indicated that the light was malfunctioning.

All lights including dash lights turned off while driving at night on the interstate at 82mph. Not sure if my knees hit the light switch or not but not sure why even dash lights went out. Brought vehicle to local Chevy garage, there was no code and they couldn’t duplicate the incident.

Three weeks ago, I exited my running truck and saw that the left front driving light wasn't working. Turned the turn signal on and it would not function either. At first the rear light was blinking normally. Then after about a minute it began to flash rapidly and the display showed, check left front turn signal. Shut it off and unit worked after restart. Two weeks later, did the same thing. This time it did not reset until the next day. It seems to malfunction when the headlights are activated, and I noticed there is a unit mounted on the back of the headlight assembly that appears to control it and the headlights, as it is one unit. I recorded it on video, and when I took it to the dealer, they were able to confirm the issue. They are going to replace that assembly. After some research, I am discovering that this is beginning to look like a common issue as others that own 2022 model years and up report the same thing. My vehicle has only 12,600 miles on it, and I have found people with 2024 GMC trucks also experiencing it. This is concerning as it is a safety issue with nonfunctioning turn signals or running lights. As I stated before, the first time it happened there was no warning that the driving light wasn't working nor was there a warning the first time it happened that the front turn signal wasn't flashing for over one minute. Most times your signal isn't on for that period of time. Mine is warranted but some people said that without proof; the dealer can't duplicate the issue, so they aren't replacing it. Out of warranty the lighting unit costs about 1,500.00 and it isn't something an average individual can replace. GM also charges a 200.00 core charge on these. The service manager called it a restricted item. I would appreciate your looking into this to see how widespread this might be. I'm assuming it has something to do with the headlights being on and the heat generated by them causing the failure, but that is just a guess. It is a safety issue though

On approximately 6 occasions over the past 12 months, either the right front turn lamp or left front turn lamp failed. Most recently this occurred on 8/27/24. When this happens, the entire front head lamp does not work. A warning on the dash shows as "Check Left/Right Front Turn Lamp" and the audible turn signal click is faster than normal. Turning the truck off for approximately 15 minutes fixes the issue until it returns again at random. Having functioning head lamps and turn signals is critical to safely operating a vehicle.

While driving approximately 20MPH and entering a left turn lane, I activated the left turn signals and discovered the driver side front turn signal was inoperative. A cluster message appeared indicating the left front turn signal was inoperative along with hearing the audible double speed "tick tock" indicating a bulb failure. When I arrived home, I also discovered the daytime running lamp (DRL) on the driver side, which shares the same portion of the lamp as the turn indicator, was also inoperative. On the next drive cycle the fault cleared itself. A non-functioning turn signal increases the risk of a vehicle crash. This is also a non-compliance with FMVSS 108, Lamps, reflective devices, and associated equipment. VOQ's 11584694, 11582809, 11577734, 11566682, 11561217, 11555917, 11548335, and 11528583 describe a similar failure and are happening early in the vehicle's life.

During the failure the exterior turn signal had become inoperable. The contact stated that the failure was intermittent. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The manufacturer was notified of the failure. The failure mileage was 4,000.
