- Some owners report the fuel pump control module failing more than once on the same vehicle, requiring repeated dealer visits.
- Vehicle sometimes struggles to start, misfires, and shakes before shutting off again one or two more times.
- One owner reported the fuel gauge showing empty despite the tank being three-quarters full.
