Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The fuel gauge is intermittently not showing the level of fuel in the fuel tank. Had to drive to the dealership when this occurred to have the technicians read the codes on the computer. If you shut the car off, the fuel gauge resets and the technicians are unable to find the error code. The dealership service department will have to order a new dashboard instrument cluster panel. The car only has 1,948 miles. This car has serious electrical issues.”
