Typical fuel system symptoms owners report

  • Sudden, uncontrolled full-throttle acceleration while stopped or moving at low speed, sometimes ending in a crash.
  • Power Conversion System (PCS) failure that reduces AC charging rate in steps until charging stops entirely, often blamed by Tesla on the outlet or home wiring instead of the part.
  • Loss of drive power on the highway where the car slows down despite the accelerator being pressed, with no warning light or sound.
  • PCS failures recurring after an initial in-warranty replacement, then being billed to the owner once the 50k mile warranty period ends.
  • One case of a vehicle fire severe enough to destroy the car, cited among Fuel System complaints.
