2023 GMC Sierra 1500 Exterior lighting Problems

While driving in the rain, the windshield wipers were on the highest intermittent setting and the high beam headlights were also on, automatic highbeams were not. The high beam lights dimmed to low, and the windshield wipers stopped in the middle of the windshield in the middle of navigating a sharp right hand turn at 35mph. The wipers stopped for approximately 30 seconds and then resumed operation. When the wipers resumed operation, the headlights also turned back on high with no input from the driver.

OTA update GM N25-250380 caused significant problems. Blinker tone and other safety tones are erratic. Infotainment system is erratic. Constant reboots while driving causing distractions. Camera screens will freeze on screen while driving down interstate. It may be affecting other systems as well since everything is erratic and buggy now.

The entire instrument panel is blacked out. I can not see the speed, how much fuel and no waring lights etc. The screen flashes between black and dark blue and there is a repetative "ding" that I have no idea what is caused from since I can not see any warning lights, etc.This puts me and others at risk due to not being able to see any functions for operation of the vehicle, the speed or any indicator lights of vehicle issues. The dealer has seen the truck, and informed me that this is a known problem and they would have to order parts. According to the service department, parts for replacement will be covered under warranty/recall and they have been on order. It has been 3 weeks and they have no knowledge of when the parts will be in to make repair. There was no warning on this problem, the panel just went out.

Was driving my 2023 GMC Sierra in a mild snowstorm after leaving the grocery store and heading home. It was about 10 minutes after dark and it has just started snowing. I was only 5 minutes down the road and the visibility in front of me suddenly & drastically declined. I could barely see the road. I could barely make out anywhere to turn out to. Once pulled over, I walked to the front of the truck and the headlights AND fog lights were completely covered in snow. I wiped them off with my hand and could then see great again. Well, 5ish minutes down the road again and they were back to completely covered. Twice I wasn't able to pull over, due to the steep terrain and no shoulder so, I had to push on, traveling at no more than 4MPH. And getting out during one of the 7 cleanings, I almost slipped and fell. It took me 48 minutes to get home. A trip that usually takes 25! The HID headlights on my other truck don't have this problem. And the aftermarket LED headlights on another vehicle of mine have built in heating elements. You would think the OEM would've thought of this option but, they don't offer it! If it wasn't for my 20+ years experience of driving in the snow, I would've been left stranded or wrecked/totalled the truck due to this major safety oversight!

The reverse lights are too dim to provide sufficient viewing of the rear of the truck when it is dark outside and there is no other lighting. Almost nothing can be seen from the rearview or sideview mirrors, and the backup camera is rendered useless. GM changed the design of the taillights such that they are now sealed, which means owners cannot upgrade the reverse lights with stronger LEDs any longer. This lack of lighting is more than an inconvenience; it is a safety issue. This is a known issue and GM is well aware of it.

I have been trying since day one of my brand new 2023 Sierra Denali pickup truck hence I spent a $100 K plus OEM accessories at the dealer ! This complaint is in reference to the safety part of the brake trailing that disconnect and lose light and brakes ! I have Spent insane times at the dealers and have complained to the GMC Executive offices with Nothing but excuses and Absolutely Zero Help from GMC Cooperate but continue to go make appointments at the dealers ! This is Safety complaint and they are not taking this seriously at all ! There is defiantly a ongoing issue with either the computer onboard or the trailer Module ! I am not a engineer but again this is a safety Issue that needs to be looked at ASAP ! I do not feel safe driving the truck !

Nighttime backing up is to dark to see in the camera. The reverse lights are not bright enough to highlight the area to see correctly. This is a major concern as i almost backed up over my child at night as i could not see them in the camera. Please address with manufacture to resolve the issue. This truck has one piece LED lights that can not be pulled and swapped out with a brighter bulb. would need to replace the entire fixture.

The contact stated that while driving at an undisclosed speed at night on an undulating roadway, the contact noticed that due to the narrow vertical area of illumination of the head lights, front visibility was severely reduced, with the lowest portion of the area in front of the vehicle receiving little to no illumination. The contact stated that the failure was not present while driving on a flat roadway. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired.
