Vehicle was parked with all doors locked and the vehicle not running. The remote unlock button was engaged and all doors unlocked with the exception of the driver door. The remote unlock was engaged 3 to 4 more times. The door was manually unlocked from passenger's side. When the door was opened, smoke was pouring out of the inside. We poured available liquids down the window slot but smoke was still pouring out. While my spouse went inside the business where we were parked to grab a pitcher of water, I jerked the plastic oval piece around the inside door handle off and saw flames. He returned with the pitcher and we poured the water down the open hole at the door handle and finally managed to extinguish the flames. We drove the vehicle home but none of the door functions worked at all. It is going to cost me approximately $600 to fix this issue. …
Inaccurate fuel level reading. In November, my fuel gauge and driver information center began to spontaneously read erratically and would not accurately show me how much gas I had. Condition has rapidly progressed to where the fuel gauge almost constantly reads empty, low fuel light is illuminated and fuel level low is displayed in the dic. In researching this issue, I found service bulletin no. 10054b which states it is a premature wearing of the fuel sensor and I should have received a mailed notice from GM regarding this known issue. I have not received any such notice. …
