“My low beam head lights keep blowing over the past two years, I have had to replace them 5 times on the driver side and 2 times on the passenger size. Also had my head light harness replaced oct due the blub breaking in multiple pieces. Jan of 2019, it rained and my turning signal blub broke again and the lighting component filled up with water and looked like a floating fish bowl.”

“Lift gate would not open, tried to open my driver door to open it from there and it still would not work. Tried to crank car and it made a lot of clicking noises and looked as if the battery was dead but then all of my doors started making clicking noises. Won't start. Won't release key.”

“My windows will roll down on their own while going down the road. I can only roll the windows up and down intermittently while parked and in motion. While driving stability control will turn itself off and blow some sort of gas through the air conditioning vents in the car, then it will start shuddering and slowing down the car to the point I have to pull over. After that issue started, my A/C will only work intermittently as well.”

My vehicle read to service stable track once again and traction control off. My truck dropped down to basically no power in the fast lane on a major highway. Thank god I said my prayers that day, and three cars that almost plowed into the back of my truck and any accidents were avoided. …”
