Top issues to watch for
The most serious Tesla Model X problems ranked by severity. We track 8 known issues — here are the ones you need to know about first.
Dangerous
Power steering system failure (GEN1)
The electric power steering system can fail without warning, displaying messages such as 'Steering Assist Reduced' or 'Steering May Require Increased Effort'. The system uses an electric motor integrated into the steering rack, which can fail due to overheating or internal electrical faults. This is reported across 37 NHTSA complaints and represents a significant safety risk.
What happens if ignoredComplete power steering failure makes the vehicle extremely difficult to control, particularly at low speeds or during parking maneuvers. This creates an immediate safety hazard. Steering rack replacement typically costs £2,000-4,000. The vehicle should not be driven with active steering warnings.

Major
CV joint boot deterioration (GEN1)
The constant velocity joint protective boots on Model X deteriorate at 8.2 times the fleet average rate. These rubber boots protect the CV joints from dirt and moisture ingress while allowing the joint to articulate. Tesla's torque delivery characteristics and the Model X's weight contribute to accelerated boot degradation. If the boot splits, the joint will fail rapidly due to contamination, requiring complete driveshaft replacement.
What happens if ignoredA split boot allows dirt and water to contaminate the CV joint, causing rapid wear and eventual failure. The joint will begin clicking during turns and may eventually seize or break apart, leaving the car immobile. Complete driveshaft replacement typically costs £800-1,500 per side.

Falcon Wing Door Issues (GEN1)
The Model X's signature falcon wing doors use a complex system of sensors, motors, and articulated hinges that frequently malfunction. Ultrasonic sensors that detect obstacles can become misaligned or contaminated, causing the doors to stop mid-operation or refuse to open. The door motors and control modules are particularly vulnerable to moisture ingress. These issues are specific to the Model X design - no other Tesla model shares this door mechanism.
What happens if ignoredMalfunctioning falcon wing doors can leave passengers unable to exit the rear seats, creating a safety hazard. Repair typically requires replacement of door control modules, sensors, or motor assemblies. Complete door mechanism replacement can cost £4,000-6,000 per door.

Major
Suspension component wear (GEN1)
Model X shows accelerated wear of suspension bushes and joints, failing MOT tests at The vehicle's significant kerb weight (2.4-2.7 tonnes) and instant torque delivery place exceptional loads on suspension components. Upper control arm bushes and shock absorber mounting bushes are particularly affected. This is a known weakness compared to lighter Tesla models.
What happens if ignoredWorn suspension bushes affect handling precision and ride quality. Severely worn components can cause tire wear and compromise safety during emergency maneuvers. Individual bush replacement costs £200-400, but multiple components often need attention simultaneously.
