2013 Isuzu D-MAX Yukon D/C Intercooler TD 2.5L Diesel · CU63 OLK

The defining mechanical story of this D-Max is one of chronic front-end wear and progressive underside corrosion, culminating in a fail at the December 2025 test. That test recorded an electronic stability control warning lamp defect, a detached offside front anti-roll bar linkage, and towbar end plates corroded to the point of Major failure, while the underside advisories confirm the chassis, suspension and brake pipes have been heavily coated with waxoyl a preservative treatment that masks the true condition of the steel beneath. The most recent pass on 8 January 2026 is encouraging, but it followed immediately after those Major defects were addressed, and the history shows a recurring pattern of advisories for front tyre shoulder wear, a noisy offside front wheel bearing (first noted on the nearside in 2021 and 2022, shifting to the offside by 2024), corroded front suspension arms flagged as early as 2022, and corroded rear cross members at the same date. The December 2024 test is particularly revealing, as the same anti-roll bar ball joint dust cover that was advisories in 2023 had split enough by late 2024 to warrant a Major failure, demonstrating a deterioration curve rather than a stable mechanical picture. With 92,010 miles recorded across roughly thirteen years, this Isuzu has averaged around 7,000 miles annually, which is broadly in line with typical light-commercial and utility use for the model. There are no significant gaps in the MOT testing record from 2020 onwards, with tests consistently falling in mid-December, suggesting continuous use rather than extended periods off the road. The mileage progression is steady, and the advisories align with what would be expected from a working vehicle accumulating consistent annual miles rather than suffering from long-term standing, with wear concentrated on the front axle components and tyres as is common on a rear-driven pickup used for towing or load carrying. For a prospective buyer, the front axle is the priority inspection area. Both front tyres have been repeatedly flagged as worn on the outer shoulder at the last three tests, which on a live-axle, leaf-sprung pickup typically points to tracking misalignment, worn front suspension bushes, or bent components following kerb impact; an uneven inner-to-outer wear pattern on any replacement tyres should be checked. The offside front anti-roll bar linkage that came detached in 2025 and the split ball joint dust cover recorded in 2024 indicate the anti-roll bar bushes and drop links are nearing the end of their service life, so listen for clonks over uneven surfaces and pay particular attention to body roll during cornering. The nearside front wheel bearing, advisories for slight play in 2021, 2022, 2023 and 2024, should be evaluated for any residual rumble or hum that changes with steering input, as the recurring advisory suggests the original bearing may have been replaced but the replacement is also showing early wear. The underside corrosion profile warrants a thorough physical inspection on a ramp, as the heavy waxoyl coating will obscure the true state of the steelwork. The 2022 advisory for corroded but not seriously weakened front suspension arms and the corroded rear cross members require close examination now, particularly around mounting points, spring hangers and the brake pipe runs along the chassis rails; any bubbling through the waxoyl, flaking scale, or holed brake pipes would be a significant concern. The central exhaust minor leak noted in 2021 and the heavily corroded towbar suggest the vehicle has seen substantial towing or heavy use, so the towbar mounting, electrics, and any rear cross member integrity should be checked directly. Finally, the electronic stability control warning lamp fault that caused the December 2025 failure should be confirmed as properly rectified with a diagnostic readout, as intermittent ESC faults on this generation of D-Max can stem from wheel speed sensor wiring damage, a faulty steering angle sensor, or ABS module issues rather than a simple bulb or wiring fix.
