I purchased by vehicle in the summer of 2015. It has been in the shop numerous times for various issues, mostly electrical involving the computer and software, or issues involving my tires or steering when turning the steering wheel.. My "driver assist" has malfunctioned many times and I have taken it to the shop to have it repaired on 3 separate occasions. Last summer my front and rear lights started flickering and stopped working. I spent $800 for the back passenger brake light and almost $1000 for the front driver head light assembly. I also had to get a new battery for this vehicle. My 2015 gmc yukon xl is now malfunctioning again and this time, I am told that the seat motor (that alerts you when you are near an obstacle has burned out.) about 4 days ago, I became aware of ticking noise while my car has been idle. I immediately scheduled a maintenance appointment. Today, I am also informed that my "lifters" are bad on the vehicle and my engine is going bad. I am told the air conditioning condenser has burned out, I am told the motor under my seat is burned out. I have performed routine maintenance, I get oil changes regularly and use high quality synthetic oils. I take my car to the shop at least 2x per year for problems and some major repair is always required. This is a car that I am going into the 5th year of ownership this summer. Originally. I was told that there was a recall for brakes, now I am told there is not, but I have taken my car in for various recalls at least 3x. This is an unsafe, defective vehicle. Every system fails. I am now in search of a new vehicle. I have driven other gm vehicles (grand am, hummer) and none have required so much repair costs. Today I am told that it will cost $6800 to repair my vehicle to make it safe. My repair records will show the repairs and service charges I have paid since purchase. This is a lemon.

Turn signal failure on the passenger side. Cause by condensation in the headlamp assembly. Cost $1300 to replace and get a new turn signal. A turn signal is $5, but then integrated leds cost $1300 because they have to replace the whole assembly.

Exterior lighting issues. Rear running lights not working. Rear break lights are not working. Right side blinker not working in front head lamp or rear lighting fixture. When the vehicle is hooked to the computer at a gm dealership the computer will not show what the issue is. This is a safety issue as I can not safety drive the vehicle at night due to no lights in the rear of the vehicle nor during the day without break lights.
