EXTERIOR LIGHTING

Drivers side head lamp adjuster broke inexplicably. I noticed while driving that the headlight was pointing down towards the ground. No warnings of any kind. I made no attempts to adjust the headlight either before or after the issue was noticed. It is difficult to drive at night because there’s essentially only one headlight working properly. The vehicle has never been in an accident. I took it to the dealer and they told me that it could not be fixed and the entire headlight assembly needed to be replaced. It’s a very extensive process that I cannot do. The cost is almost $2000. I contacted a local repair shop and they quoted a similar price. I contacted GM and they said it was up to the dealer to determine if they would offer cost assistance for the repair. The dealer refused. GM accepted their decision and could not help with the cost. How do they expect someone to afford this cost? It’s not a part they ever expected that needed to be replaced or else it would not require the front bumper to be removed. The light is designed to last as long as the vehicle so why would they not fix an obvious defect. I’ve seen others online complaining of the same problem. The adjuster arm is made with cheap plastic and separates inside the assembly. There’s no way to get to it. It is unsafe to drive at night. I cannot see the road and any light reflectors on the center line flash in my eyes because there’s essentially only headlight is pointing directly at them.

I recently purchased this vehicle from a dealer in FL, but unknown to me at the time was the headlight adjuster on driver side was broken, causing the aim to drop to the bottom limit. This causes only the passenger side light to illuminate the road. I discovered this problem about a week after purchase. The dealer does not seem to be willing to correct this issue. This is a common problem for these vehicles, verified with online search's. The fix is to replace the entire headlight housing which is quite expensive, and then the labor to remove and replace the front bumper assembly.

As many have already complained, the headlight adjuster screw for the drivers side of the headlights of the vehicle always break or get stripped out even at low mileage, causing the headlight of the drivers side to point down onto the road and being unable to illuminate anything past the very front of the vehicle at night. This is a serious hazard that is not possible to fix or adjust without a large bill at the dealership. The drivers side headlight is pointed down and me myself, has resorted to adjusting the passenger side headlight to point up to compensate for this issue. This is causing many safety issues as I cannot see anything past 1-2 feet from the front.

Driver's side headlight adjuster screw breaks very easily, and makes the headlight beam be too low with inability to adjust it. There is no way to replace it... it requires a change of the entire headlight, which requires removing the entire grill. A cheap piece that makes customers pay thousands of dollars in repairs. There are a myriad of reports of this issue online, for example here: https://www.tahoeyukonforum.com/threads/headlight-adjuster-broken-again.144355/

Headlights are unable to be adjusted using the headlight adjuster leading to a safety issue when operating the vehicle at night. Headlights point down and don’t light up the road properly during night time driving.

The 2015 Chevrolet Tahoe seems to be known for thermostat failure. My thermostat gauge while driving would drop from 210 to 160 and stay pinned on 160 and the fans would turn on. I was told by an auto body shop that it seemed to be electric issues. I also had a wire under the car catch fire and the auto body shop said that is why my standing lights would not work in the rear but my brake lights would work. It’s very dangerous that the electrical failure caused a fire to start under the car. Then, I ran into another issue just this week where the vehicle has a cracked AC condenser and is slowly losing coolant. It’s a manufacturing issue because all of them seem to crack and we’re not made with a proper seal. Another electrical issue I have is when I turn the wheel all the way to the left or right, even when the key is in and engine is on, the engine will shut off. The car completely shuts off and then I have to turn the key to the off position and then it will turn right back on. The steering wheel is also losing power steering and gets very tight when I have to make a turn. The fuses for my radio are blown and when you put new ones in, it blows immediately and doesn’t turn on. I have MANY issues with this vehicle and it’s obviously a manufacturer issue. This is not ok for a vehicle to all around have such horrible electrical issues. I have had issues driving over a pothole and I lose my radio screen or my whole dash screen and then the dealer and auto body shops say the electrical work is too in depth for them.

EXTERIOR LIGHTING

We were driving our 2021 Chevrolet Tahoe (purchased Dec 2020; odometer currently right under 40,000 miles) out of town this past weekend and I noticed the headlights were not illuminating the road ahead very well once the sun went down. They seemed like they were pointed down and when i turned on the high beams, those were also lower than how the low beams are usually pointed. We were stuck in the middle of nowhere and I persevered with low lighting onto our destination. After researching the issue on the internet days later, I found a Tahoe Owners' forum/thread [XXX] ) where several other 2021 Tahoe owners had experienced the exact same issue as ours had. The culprit appears to be a sub-component of the headlight adjuster mechanism, but GM/Chevrolet does not offer a replacement for either this small white plastic piece that is failing and the only repair option they have for this issue is complete replacement of the entire headlamp assembly ($1,350 MSRP). This is a dangerous problem that occurred randomly on a vehicle with low mileage and appears to potentially be a common failure for other owners of the same headlamp design. I have not taken this vehicle into the dealership for inspection, as I expect they will only replace the entire headlamp assembly for $$$$.

The headlight adjustment screws fail causing the projector adjustment to bottom out leaving limited visibility when driving in the dark. The headlights then do not raise back up any longer.

I'm [XXX] so not much night driving. The other night I left a meeting when I turned on headlights one is pointing down. Difficult to see and hard to stay between the lines. My vehicle has never ben in an accident nor had lights repaired. Checking online I see this is a problem for many Tahoe, Suburban and Yukon owners and perhaps even pickup trucks. In my opinion this represents a serious safety concern. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving at night in the rain. The front windshield wipers paused in an upright position for 3-5 seconds and all exterior illumination/lighting went out. They all came back momentarily.

My issue with the vehicle is that the reverse lights do not project enough and when backing up at night you can not see it or even with the back up camera. It’s poor placement of the light and does not provide adequate light when backing up. I have not had any incidents with it but I feel like it is a huge potential problem

I've had my 2023 Tahoe for 15 months, purchased Dec. 2023 Issue #1. Dash message on start up " Restraint System Needs Service". I noticed small lights overhead (buttons for tail gate, sun roof, reading lamps) were off. I pressed some of them, and dash message went away, and lights came on. Everything worked fine. I've narrowed it down to the passenger side reading light. When dash warning comes on, I press reading light, and whalla! all works fine. This has happened about 6 times over the last year. Issue #2. After driving many hours (9 hr drive, then a 2hr drive, then 4hr hr drive on different days/nights) in rain with wipers in auto mode, using defrost on and off as needed. Suddenly, wipers stop working as well as headlights in auto mode! Scary. Pulled over and waited with engine off. Restarted and still nothing. I was able to use headlights in full ON mode. I turned the wiper switch all the way from top-pulse to the full-on 4-6 times really quick back and forth, and like magic, everything worked again! This has happened 3 times in the last 2 months (always during several hours of rainy weather driving). Dealer says they can't fix what they can't witness. I suppose my only recourse is to video tape it and then show dealership.
