The day light running lights will not go off preventing the low beam light from lighting properly. 08/21/2025.
Headlight assembly leaks and retains significant amounts of water resembling a half filled fish tank. This causes the bulbs to burn out or corrode the light power supply leaving you with no headlights! this is a very common problem across many gm platforms. I am surprised the government regulators have allowed a safety problem this wide spread and known to continue unaddressed.
Driving today in snow, increased electrical demand on vehicle while accelerating. Smelled burning wires and all dash lights flickered then died. Engine turned off and had to be restarted with the push button. Happened within 30 minutes later while accelerating onto a main road with traffic, lost control of vehicle and had to force the steering wheel to turn the vehicle off the road to avoid being hit by oncoming traffic.
The headlamps do not provide sufficient light output to safely operate the vehicle at night. It is very easy to over drive the vehicle headlamps and the bright lights do not provide enough increase in light output to address the issue. I do not feel safe operating this vehicle at night in any reduced light condition.
Trailer brake assist malfunction during trip while driving with trailer connected on highway no problem after ending trip and disconnecting trailer brake assist warning light appeared and 1st glance brakes seemed fine but final pedal pressure is very stiff almost can't stop SUV.
Especially at night, the "welcome lights/reverse lights" of a Chevrolet Suburban confuse me because I think that person's vehicle is backing up. This causes me to either hesitate or at worst, panic if I think they are about to back into me. The photo attached is of a different gm vehicle, the GMC terrain, but the appearance is the same.
Headlamps too dull. Hard to see the road at night. No side vision at night. Has been like this since new. I have complained to 2 different dealers and they say there is no problem. I have put in a complaint the the manufacturer and have heard nothing back.
