Top failures
Suspension arm pin/bush excessively worn 6.2%
Worn suspension arm bushes allow the wheel to move unpredictably, affecting steering, handling and tyre wear.
Parking brake efficiency under half required 5.86%
The parking brake is well below required strength and is unlikely to hold the car on a slope.
Parking brake efficiency below minimum 5.78%
The parking brake holds the car less well than required, so it may roll on a slope and needs repair.
Track rod end ball joint excessively worn 5.06%
Worn steering ball joints can affect steering control and safety, so repair is needed before the car is driven.
Position lamp not working 4.76%
A failed position lamp makes the car harder to see in poor light and is illegal, so it must be repaired.
Parking brake inoperative on one side 3.93%
The parking brake does not work on one side, so the car may not hold on a slope and needs repair.
