Cars of this vintage present for MOT with an average of 98,820 miles on the odometer. With a 47.1% failure rate, the 1999 Trooper Duty V6 Swb is rated as "Poor" for MOT reliability.

If you own or are considering buying a 1999 Isuzu Trooper Duty V6 Swb, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to suspension: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks. With an average mileage of 98,820 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.

Suspension — 23.5% of failures

Suspension issues account for 23.5% of MOT failures on 1999 Isuzu Trooper Duty V6 Swb models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.

Body, chassis, structure — 23.5% of failures

Body, chassis, structure issues account for 23.5% of MOT failures on 1999 Isuzu Trooper Duty V6 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.

Noise, emissions and leaks — 17.6% of failures

Noise, emissions and leaks issues account for 17.6% of MOT failures on 1999 Isuzu Trooper Duty V6 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.
