2015 Chevrolet Tahoe lights problems

Filed Jul 7, 2025 · Electrical, Lights · NY

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.

I have not had a wreck but the fact that when you press the brake pedal the dome lights blink and when you turn on the left turn signal, the dome lights blink. If you hold down the brake like if you’re at a traffic light the dome lights blink continuously until you let off the brake. Now, during the day, that’s no big problem but at night it poses a serious safety risk. A bright light in your eyes while driving is blinding and a sudden bright light in the pitch black dark could lead to an accident. I called the dealer to ask about it and was told yeah, they knew about it and it would cost me like $550 to repair even though it was a defect that they readily acknowledge.

On several occasions at various speeds, both driving straight and turning, my 2015 Chevy Tahoe has turned off. During higher speeds the SUV will turn back on, instantly, by itself but during lower speeds and turning the car has to be manual turned back on by switching into neutral, pressing the break, and pushing the start button. The most recent time this has happened, it was dark outside and I was turning. I lost everything including my head and tail lights so it was hard for oncoming traffic to see me. I also almost hit someone coming in the other lane because I was unable to fully turn due to the loss of power steering. After this happens, I get many warning/action required messages across the dashboard but no check engine light or code have come up. I will be taking it to the dealer but since it does not happen every time the care is driven, I can only hope they can experience what happens.

Dome lights keep flickering. Not specific to any light. All of them flash sporadically. Looks like a camera flash at night. It is beyond distracting at night and the dealership could not find what is causing it to happen. It is making driving at night dangerous because it is distracting because it can sometimes flash non stop like a strobe light.

The electrical software isn't functioning properly. The radio, onstar, the door/seat belt chimes don't work. None of the electrical works in the vehicle.

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.
