Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The fuel pump power control module caused the fuel pump to fail and resulted in unexpected engine stall. The issue cause me and my 4 children to be stuck in the middle of the road waiting for a tow truck for over 3 hours. The vehicle could only be put in neutral while the car was on. Since I couldn’t start my car I could not put it in neutral to move the vehicle out of 2 way traffic. We want the issue confirmed by the dealership but the police who aided me and my children inspected the vehicle and recommend getting the fuel pump look at. No warnings were displayed.”
