  • Some owners report sudden loss of acceleration or engine power at highway speed, later diagnosed by a dealer as a fuel injector issue.
  • Owners describe a fuel vacuum sensor repeatedly triggering a warning to tighten the gas cap, with a mechanic tracing it to dirt entering the fill area and needing sensor and filter replacement.
