About This Data
The 1991 Mitsubishi Pajero Gl Swb has an MOT pass rate of 56.3% based on 112 tests — slightly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 142,404 miles on the odometer. With a 43.7% failure rate, the 1991 Pajero Gl Swb is rated as "Below Average" for MOT reliability.
If you own or are considering buying a 1991 Mitsubishi Pajero Gl Swb, budget for potential repairs before each MOT. Before your MOT, pay particular attention to body, chassis, structure: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely. With an average mileage of 142,404 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Body, chassis, structure — 5.4% of failures
Body, chassis, structure issues account for 5.4% of MOT failures on 1991 Mitsubishi Pajero Gl Swb models. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
Brakes — 5.4% of failures
Brakes issues account for 5.4% of MOT failures on 1991 Mitsubishi Pajero Gl Swb 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).
Noise, emissions and leaks — 4.5% of failures
Noise, emissions and leaks issues account for 4.5% of MOT failures on 1991 Mitsubishi Pajero Gl Swb 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.
