What actually goes wrong
The most common MOT faults across the Perodua range, in plain English. Models with more MOT tests count for more. The percentage is the share of MOT tests on Perodua cars that recorded that defect.
Suspension joint, pin or bush
A suspension ball joint, pin, or rubber bush is worn or has excessive play. These are the pivot points and flexible mountings that let the suspension move — wear causes knocking sounds and vague steering.
MOT wording: Suspension arm pin or bush worn, but not moving too much
Rigid brake pipe
A rigid metal brake pipe is corroded, damaged, kinked, or leaking. These permanently fixed pipes carry pressurised brake fluid — any weakness is a serious safety concern.
MOT wording: Brake pipe corroded or covered in grease
Tyre slightly damaged, cracking or perishing
A tyre is worn, cut, damaged or otherwise not fit for the road. Tyres are the only thing connecting the car to the road, so this is always worth taking seriously.
Tyre worn close to the legal limit or worn on the edge
A tyre is worn, cut, damaged or otherwise not fit for the road. Tyres are the only thing connecting the car to the road, so this is always worth taking seriously.
