All Known Issues

Clutch Master Cylinder Failure

SeriousGearbox & Transmission

Heat from the engine/exhaust boils the fluid and degrades the seals. The pedal will stick to the floor, often requiring a "clam-off" repair.

Est. Repair Cost: £1,000–£1,800
Warning Signs:

Clutch pedal sticks to the floor, Low bite point, Difficulty selecting 1st or Reverse

What to Inspect:
  • Check for fluid leaks in the driver's footwell.
  • Test the pedal feel after the car is hot.

Door Latch & Window Niggles

ModerateElectrics & Electronics

The door release mechanisms and window drop functions are prone to failure, often requiring the replacement of the door latch assembly.

Est. Repair Cost: £400–£900 per door
Warning Signs:

Door won't open from outside, Window doesn't drop when pulling handle, Central locking failure

What to Inspect:
  • Operate both doors and windows multiple times.
  • Check if the window seals correctly against the roof.

Air Conditioning Evaporator Failure

ModerateCooling System

Similar to the Elise, the A/C system is a weak point, with the evaporator being a labor-heavy "dash-out" job to replace.

Est. Repair Cost: £1,500–£2,500
Warning Signs:

A/C blows warm, Musty smell in cabin, Rapid loss of refrigerant

What to Inspect:
  • Confirm the A/C gets properly cold.
  • Check for "re-gas" history (often masking a leak).
