  • 120,642 miles
Vehicle would not start. When they put it on scope they found that the fuel rail pressure was to low. They found metal shavings throughout the fuel system as if a part was coming apart from the inside. They had to replace entire fuel system from pump to injectors plus all the lines and injection pump. This vehicle is 2 years old.
