Most Common McLaren GT Faults & Repair Costs
Tailgate Latch and Sensor Niggles
The electric rear tailgate can occasionally fail to latch correctly or show a "Boot Open" warning when it is actually closed.
Tailgate doesn't open/close via button, Warning light on dashboard
- Operate the tailgate several times using both the key and the internal button
Software Connectivity Issues
Owners have reported occasional glitches with the smartphone integration and navigation system.
Phone doesn't connect, Nav system freezes
- Ensure the car has the latest firmware
Power Tailgate Motor Failure
The electric motor that operates the rear tailgate can fail or become sluggish, particularly on higher-mileage cars. The tailgate may fail to open fully, close slowly, or stop mid-operation. The motor assembly is not cheap to replace.
Tailgate opens slowly or not at all, Tailgate stops mid-operation, Grinding noise from tailgate motor, Tailgate warning light
- Operate the tailgate multiple times and observe speed
- Listen for grinding or hesitation
- Check if the tailgate completes its full travel
Luggage Area Trim Wear
The GT's party piece is its large rear luggage compartment, but the leather and trim in this area can scuff and wear prematurely, especially if luggage is loaded frequently. The area sits directly above the engine bay and is exposed to heat.
Visible scuffs on luggage area leather, Trim pieces becoming loose or creased, Discolouration of leather from heat exposure
- Inspect the luggage area leather for scuffs and wear
- Check trim pieces are secure
- Look for heat-related discolouration near engine bay
Brake Dust and Carbon Ceramic Maintenance
The GT uses carbon ceramic brakes as standard. While they last much longer than steel discs, the pads still produce significant dust that can coat the wheels. Pad replacement when eventually needed is very expensive. The calipers can also develop surface corrosion if the car is stored in damp conditions.
Heavy black brake dust on wheels, Scoring on wheel faces from dust, Surface corrosion on caliper bodies
- Inspect wheels for excessive dust and scoring
- Check caliper condition for corrosion
- Ask about brake pad thickness and history
ABS/ESC Brake Line Recall
The GT was included in a McLaren recall for incorrectly routed rear brake pipes that could cause the ABS and ESC systems to malfunction. This could lead to a loss of vehicle control.
ABS/ESC warning light, Unusual braking behaviour, Rear wheel locking under braking
- Verify recall completion via VIN
- Check for brake warning lights
- Test ABS function
