What owners wrote
Tl* the contact owns a 2007 chevrolet avalanche. The contact stated that the check engine warning light illuminated and the vehicle suddenly would not accelerate. The vehicle was taken to an independent mechanic, who diagnosed that the number 7 coil pack was defective. The mechanic replaced the number 7 coil pack and the number 7 spark plug to correct the defect. Additionally, the front passenger's side interior door handle would cause lacerations to the contact's hand when attempting to exit the vehicle.
I drove to work & parked my 2007 avalanche in my employers truck garage as I do every day. I went into the office attended a job briefing & we put on our coveralls for work then we got ready to leave to go to the 1st jobsite but as soon as the 1st two coworkers walked out of the shop they turned around yelling that my truck was on fire. I didn't believe them at 1st because I had just parked like 15 minutes prior. Parked & not running. Well I looked and my whole engine compartment was full of flames.
