Left me stranded on the roadside. If I would have drove it any further it would have costed me an engine. The oil light flashed on and off and my car sounded like a tractor. No warning.”

With a truck on one side and another barreling down my behind, I tried to accelerate but the vehicle began to shudder and shake violently!
