About This Data
The 2004 Mitsubishi Challenger has an MOT pass rate of 63.0% based on 146 tests — around the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 168,893 miles on the odometer. With a 37.0% failure rate, the 2004 Challenger is rated as "Average" for MOT reliability.
If you own or are considering buying a 2004 Mitsubishi Challenger, 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 168,893 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Body, chassis, structure — 8.2% of failures
Body, chassis, structure issues account for 8.2% of MOT failures on 2004 Mitsubishi Challenger 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.
Seat belts and supplementary restraint systems — 6.2% of failures
Seat belts and supplementary restraint systems issues account for 6.2% of MOT failures on 2004 Mitsubishi Challenger models. Seat belt failures include frayed or cut webbing, faulty retractors, buckles that don't latch properly, and missing or damaged anchorages. All fitted seat belts must be functional. Typical repair costs: £50–200 per belt. Pre-MOT check: Pull each seat belt fully out and check for fraying, cuts, or fading. Ensure each belt retracts smoothly and the buckle clicks securely. Check the pre-tensioner warning light on the dashboard.
Brakes — 5.5% of failures
Brakes issues account for 5.5% of MOT failures on 2004 Mitsubishi Challenger 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).
