general problems of the 2021 Chevrolet Tahoe

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.

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.

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.

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. . Read more...

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 71 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.

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.

Drivers side headlight is stuck pointing down making it hard to see in the dark. Vehicle is a marked police patrol vehicle.

At 13,540 miles, the drivers headlight started pointing to the ground instead of out front of the car. The headlight adjuster screw (inside the complete headlight assembly) had failed and was replaced under warranty. Then again at 35,250 mile the same thing happened again. Dealer claims gm will not do a goodwill warranty and wants $350-400 to take the headlight assembly off he car and send pictures to gm to see if gm will assist with replacement costs. Obviously this is a manufacturing defect or quality control issue. As 90% of my driving is done at night, it is unsafe for me to drive this vehicle at night.
