Engine

83 reports2 crashes3 fires
“I purchased a 2012 Chevy Sonic with 65k miles on it from Carvibe LLC earlier this month. When I took it into Firestone for a full inspection, they found that the car has severe rusting to the mechanical parts along with the body of the vehicle - the entire structure of the vehicle is compromised. Someone spray painted the rust black but Firestone was still able to see the covered up rust. Firestone has deemed the vehicle unsafe to drive.”
