All Known Issues

Falcon Wing Door Sensors

ModerateBodywork & Rust

The complex sensors (ultrasonic and capacitive) in the falcon wing doors can fail, leading to "ghost" obstacle detection where the door stops opening or refuses to open at all.

Est. Repair Cost: £300–£800
Warning Signs:

Door stops mid-opening, False obstacle detection, Door won't close flush, Warning chimes

What to Inspect:
  • Open and close doors multiple times
  • Check for uniform panel gaps when closed
  • Inspect seals for pinching or damage

Front Half-Shaft Shudder

ModerateGearbox & Transmission

A shudder or vibration felt through the floor and steering wheel under hard acceleration, caused by excessive wear in the front drive shafts (half-shafts).

Est. Repair Cost: £600–£1,200
Warning Signs:

Vibration under heavy acceleration, Wobble felt at 30-50 mph, Clicking noise when turning

What to Inspect:
  • Accelerate hard in "Standard" or "High" suspension modes
  • Feel for vibration through the accelerator pedal
  • Check for grease leaks on CV boots

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: £400–£900
Warning Signs:

Creaking when steering, Thumping noise over speed bumps, Vibration through steering wheel

What to Inspect:
  • Check for play in front wheels while car is lifted
  • Listen for noises during low-speed maneuvers

MCU1 eMMC Memory Failure (Recall 21V035)

ModerateElectrics & Electronics

Like the Model S, early Model X units with MCU1 infotainment systems are prone to eMMC memory failure, leading to a black screen and loss of critical functions. A recall (21V035) covers the replacement of the daughterboard with an improved 64GB chip.

Est. Repair Cost: £0–£1,800
Warning Signs:

Screen freezing, Slow response, Bluetooth/WiFi connectivity loss, Total screen failure

What to Inspect:
  • Check if the MCU has been upgraded to MCU2
  • Verify if the recall work has been performed
  • Test the responsiveness of the navigation

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.

Est. Repair Cost: £200–£1,500
Warning Signs:

Yellow line around screen perimeter, Discoloration of menus, Ghosting on edges

What to Inspect:
  • Inspect screen with a white background
  • Check if UV "fix" has been applied by Tesla
  • Verify touch sensitivity in affected areas
