NHTSA complaint #10692503, filed 2015-03, 35,000 miles“The vehicle stalled, engine quit, on a busy side street. The driver pulled over on the dirt side of the street.

The fuel tank was filled with 5 gallons of gasoline where the vehicle started fine and driven home. The cause was found out to be a faulty fuel indicator. It later freezes on half full even if it is filled to full tank at the gas station. Fuel gauge readings are incorrect and intermittent. …”
