general problems of the 2021 Chevrolet Suburban

2021 Suburban lt. Driver side headlamp adjuster failed while driving. Wife struggles to see at night so when the adjuster failed the driver side headlamp faced right to the ground causing no projected illuminating light. We attempted to adjust the light when she arrived home but it would not adjust due to the leveler failing and breaking. Looking into the matter we found out that numerous people with those, Suburban's and even silverado's that share the same parts have also reported the part failing due to the leveling being so thin and driving over bumpy roads will cause the weight of the lamp to snap and break. Its a growing concern yet dealerships are charging customers over 1400 to replace the whole assembly as it is one seal piece. There was no indication of it starting to fail just the moment it went from fine to facing the ground. We tried to run through extended warranty but claimed denied stating us touching the leveler to adjust it is what caused it to break. We tried to prove our case that doing research they would find to be common but no luck. Its a safey matte. R.

The front headlight leaks water which pools inside the led front headlight bezel causing the headlamp to blow/fail. This is a known gm issue and TSB's have been initiated. Concern was confirmed by the dealership who reported that the seal on the headlamp had failed causing the water leak and full replacement of the headlamp/headlight bezel needed to be replaced.

The headlight adjustment screw is broken. Was never used or adjusted and now the headlights point to the ground. Gm does not offer a replacement part for the adjustment screw, the only fix is to purchase a whole new headlight assembly which is roughly $1,000 before installation costs. This causes a dangerous situation since the drivers side headlight points to the ground and it is hard to see in front of you at night.

The headlight adjuster failed. As a result, the headlight points straight down creating a safety issue at night. I have read online this is a common problem on Suburbans and tahoes. This happened on my car around 60k miles and only ~3 years.

The headlamps are defective and unexpectedly break causing them to aim basically straight down towards the pavement making it unsafe to drive at night. In February of this year I took the vehicle to cox Chevrolet in bradenton and they said the headlamps would need to be replaced and it would cost several thousand dollars. I rarely need to drive at night and have been taking our son's car since then. There is a chance one broke and I didn't notice at first then the second one but, at this point, it is unsafe to drive the vehicle at night. I have found several posts on online forums where owners of other gm/Chevrolet vehicles with the same headlamps have had the same experience. Some have mentioned that an adjuster pin breaks and is not repairable (which I have confirmed with a service advisor at another Chevrolet dealership). I am [xxx] who drives responsibly (I. E. Not going off road in my Suburban) so having an issue like this is of concern as it makes the vehicle suddenly unsafe to drive at night. This is not a defect that is noticeable during the day so anyone purchasing a used vehicle with this problem wouldn't know they essentially don't have headlamps (I can see maybe 10 feet in front of the car) until they get on the road at nighttime.

While night driving driver noticed the driver side headlight completly pointing down providing no visibility. Vehicle was brought into gm dealership where is was discovered the driver led headlight adjuster screw broken causing a safety issue, where the light beam pointed down. Vehicle light assembly is currently being inspected for replacement under manufacture warranty under 36,000 miles.
