Most Common Tesla Model X Faults & Repair Costs

Moderate Risk

Falcon Wing Door Sensors

Est. Cost£300–£800

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.

Warning Signs:

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

Moderate Risk

Front Half-Shaft Shudder

Est. Cost£600–£1,200

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).

Warning Signs:

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

Moderate Risk

Suspension Creaking & Thumping

Est. Cost£400–£900

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.

Warning Signs:

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

Moderate Risk

MCU1 eMMC Memory Failure (Recall 21V035)

Est. Cost£0–£1,800

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.

Warning Signs:

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

Low Risk

MCU Yellow Screen Border

Est. Cost£200–£1,500

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.

Warning Signs:

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

Essential Pre-Purchase Step

Buying a used Tesla Model X? Always check for hidden finance and write-off history.

Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.

Inspection Checklist for Tesla Model X Buyers

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
