Not long after I purchased my tahoe new I noticed moisture in the headlights, more so on the passenger side. I had the vehicle brought in for an AC recall and the dealer didn't notice or fix the problem. After the warranty expired I started getting accumulating water in the light assembly which would corrode the blinker holder making it inoperable. So I either have to change the blinker holder or replace the entire light assembly. I feel like the dealer should have noticed the issue when it was in the shop for the AC recall.

When I hit a bump the steering locks up for a quick second and all the warning lights flash quickly. The doors lock as well. It is usually when I hit a bump on the passenger side area. Voltage meter flickers and headlights dim.

My 2015 chevrolet tahoe ltz's headlights have developed condensation inside of them. The driver side light has an inch of standing water in it and now the turn signal and LED running light no longer work on that side. Chevrolet said it will cost over $2,000 to replace both headlights. I know several other tahoe owners that have the same problem and our local police department has also had to replace headlights in several of their patrol tahoes. Chevy needs to issue a recall on their defective product!!!

The front left headlight is in excellent condition but fills with condensation upon washing the vehicle and during rain storms. When driving at night under these conditions visibility is poor. This is a safety hazard and needs to be rectified by gm with a safety recall.

I purchased my vehicle'2015 chevy tahoe lt on july 1, 2019 I have had intermittent glitches in the electrical system. The headlights, dash lights, and mylink touchscreen will completely black out and then come back on. However, when this happens the steering wheel locks up for a split second. This is happening while driving, at speeds over 50mph, during the night and day. It was suspected to be the alternator or battery, after replacing the alternator there was no change in the behavior. It continues to happen. The service stabilitrack warning will also pop up after the power is restored. This issue is very dangerous and after reading dozens of forums it's clear this is not an isolated incident. This has happened over and over at least 20 times since july 2019, randomly and completely unexpectedly.

Driver side seat buckle doesn't latch at all times. Also all interior overhead lights 'disco lights' flicker when the brake pedal is pressed or the turn signal is used.

The left headlight assembly had moisture and the left turn front turn signal quit working causing an error code. The dealer said there was no recall so I had a body shop replace the entire assembly. Approximately 2 months and there is moisture in the new left headlight. This is a safety issue.

When turning on the brights on my 2015 chevytahoe the dash screen will flash on and off, as well as shut off the cruise control when on. In addition, the stabilitrak will flash an error message. In addition to all of this the headlights flash while driving. At night this is very scary and harmful. These electrical issues need to be corrected!

Condensation collecting inside of both headlight covers. I have paid $200.00 for a turn signal replacement. Now getting another failure warning on same headlight and the dlr is out on the opposite side of vehicle. I was told dealer it would cost 2000.00 to replace both gaskets. Gm has issued service bulletin stating the problem could be caused by the vehicle being exposed to rain?? Or car washing. I noticed condensation while parked in garage

Heavy moisture is accumulating in the front left headlight with no cracks in the light. It is causing the left front turn signal to malfunction with a warning on our instrument panel. This causes a dangerous situation when when making left turns as the left turn signal is inoperative. Chevrolet is not accepting ownership of the faulty design, or part, or system and wants us to assume responsibility for the quoted $1200 in repair costs just to replace one headlight assembly. The extended warranty we purchased also won't cover it. I'm finding out through research that this is a common problem on this vehicle. Just over 50k miles on the vehicle! These should be recalled!
