2008 Isuzu Rodeo 2.5L Diesel · SL08 RZN

The Isuzu Rodeo presents a mixed maintenance picture. The most recent test on 25 July 2023 at 103,857 miles passed cleanly with zero defects, which is a positive sign. That clean result came just twelve days after a serious failure on 13 July 2023 at 103,856 miles, where the tester flagged severe corrosion to the rear integral body structure at the fuel tank mount crossmember and a corroded nearside front brake pipe. The fact that both issues were rectified within a fortnight suggests a focused repair effort rather than neglect. However, the underlying pattern is not reassuring. The same nearside front brake pipe defect appeared as an advisory in 2021, failed in 2022, and failed again in 2023. That is a three-year recurring fault on a single brake line, pointing to either a poor initial repair or an ongoing corrosion problem that was patched rather than properly resolved. The structural rust failure in July 2023 is the most concerning entry. Corrosion severe enough to significantly reduce the rigidity of a load-bearing crossmember is not surface rust. It implies the vehicle may have stood for extended periods or been driven in conditions that accelerated underbody decay. The mileage profile is unusual. At roughly 5,770 miles per year over eighteen years, this is well below the UK average. The record shows the vehicle covered just 634 miles between the May 2021 test at 100,833 miles and the May 2022 test at 103,222 miles, then effectively stopped moving entirely. From June 2022 through July 2023, the odometer advanced only 635 miles over thirteen months. That is not low use. That is near-static. Vehicles that stand for long periods develop specific problems: brake calipers seize, brake discs corrode, suspension bushes perish, brake lines rust from the outside in, and structural members rot where moisture collects. The MOT record reflects exactly this pattern. A buyer should inspect the rear crossmember and fuel tank mounting area in person, even though the July 2023 pass confirms a repair was carried out. Ask whether the corroded section was welded or patched, and check whether the repair was done to a structural standard rather than a cosmetic one. The nearside front brake pipe demands close scrutiny. If the pipe was replaced in 2023, verify the routing and condition of the remaining brake lines, particularly at the rear where imbalance was flagged in 2022. The fractured offside rear leaf spring from the May 2022 failure was replaced, but leaf springs on a vehicle of this age and type should be checked for cracks, sag, and worn bushes. The prop shaft joint advisory from 2021 was never revisited in later tests, so its current condition is unknown. Given the near-zero annual mileage, tyres may look legal but could be perished from age rather than wear. Check the date codes.
