What owners wrote
My car is equipped with a push to start/stop (keyless) "feature". I pulled my car into the garage last night (with the radio off), pressed the start/stop button to stop the engine, and went inside. When I woke up this morning, the car was still running, all night inside my attached enclosed garage. Co meter measure non-zero ppm levels a few hours after shutting the car off. Other then the radio, there are no obvious non-audible indications that the engine is running / not running.
Purchased as new vehicle. From the time of purchase I smelled gasoline in garage after parking overnight. After 1,000 miles/3 months the gas smell became increasingly stronger and gas mileage plummeted from 30 mpg to 18 mpg. Took the car to the dealer for repair. They said the seams of fuel tank were leaking--entire tank had to be replaced; not safe to drive.
