I took my car to have it serviced on friday and they said I had a gas leak which I hadn't noticed. I had even smoked in my car on the way to the station. When they was emptying the gas tank something sparked and caught the car on fire which ended up destroying my car and 3 others plus the station.
Oil leaks out of the top of the engine when first driven, causing vehicle to smoke until oil is burned out. Vehicle also dies unexpectedly when driving in hot weather. The ignition has been replaced three(3) times by consumer using rebuilt, new and manufactured parts.
The engine stalls at gear engagement due to coolant thermostat, the dealer was unable to determine the cause. Nlm
Vehicle would stall in traffic after stopping. Normally in the middle of an intersection. Thermostat was binding, causing it to stall. Dealer's diagnostic machine wasn't reading what problem could have been.
When riding in traffic vehicle stalls after a period of sitting and trying to accelerate. Dealer has been contacted. Problem was suppose to be fixed, but vehicle is still stalling.
Front seat belt failed to retract, back into place after use. Would get trapped into the seat cushion. Taking vehicle to dealership.
