Est. Repair Cost: £300–£800

Front Half-Shaft Shudder

ModerateGearbox & Transmission

Suspension Creaking & Thumping

ModerateSuspension & Chassis

Like the Model S, the heavy Model X is prone to premature suspension wear. Front lower control arms and sway bar links are common failure points.

Est. Repair Cost: £0–£1,800

MCU Yellow Screen Border

MinorInterior & Trim

A yellow tint or border can develop around the edges of the main 17-inch touchscreen due to a defect in the adhesive used in the display stack.

Buying Tips for 2017–2018 Tesla Model X

  • Test the Falcon Wing doors extensively on both flat and sloped ground
  • Check for a shuddering sensation under hard acceleration which indicates drive shaft wear
  • Inspect the panoramic windshield for any chips or cracks, as replacement is very expensive
  • Like the Model S, 2023+ models are Left-Hand Drive only in the UK
