  • Fuel system faults trigger limp mode or repeated stalling, with one case tied to a faulty fuel pump and another to an 'Electronic Fuel System Failure' message with the check engine light on.

  • An engine compartment fire occurred overnight while the vehicle was parked and unattended, with the fire department listing the cause as failure of equipment or heat source.
