The 2001 Proton Impian has an MOT pass rate of 48.0% based on 1,314 tests — significantly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 76,107 miles on the odometer. With a 52.0% failure rate, the 2001 Impian is rated as "Very Poor" for MOT reliability.
The leading cause of MOT failure for the 2001 Proton Impian is Brakes, responsible for 0.5% of failures. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs range from £150–400. Steering is the second most common issue at 0.3%. Noise, emissions and leaks follows at 0.3%.

About This Data
The 2001 Proton Impian has an MOT pass rate of 48.0% based on 1,314 tests — significantly below the UK average for UK vehicles.

If you own or are considering buying a 2001 Proton Impian, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to brakes: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm). At 76,107 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Brakes — 0.5% of failures
Brakes issues account for 0.5% of MOT failures on 2001 Proton Impian models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Steering — 0.3% of failures
Steering issues account for 0.3% of MOT failures on 2001 Proton Impian models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: £150–600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.
Noise, emissions and leaks — 0.3% of failures
Noise, emissions and leaks issues account for 0.3% of MOT failures on 2001 Proton Impian models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
