2004 Suzuki Grand Vitara 2.0L Diesel · YH54 KVG

A pattern of corrosion-related advisories on the rear brake pipework and a prior CV joint boot failure define the mechanical history of this 22-year-old Grand Vitara. Across five recorded tests since June 2023, the vehicle has passed four times but carries a meaningful backlog of wear items, most notably the recurrence of the offside rear brake pipe corrosion advisory at both the 2025 and 2026 tests, where the pipe was noted as covered in grease or other material. The 2023 test exposed a more serious issue, with both front outer CV joint boots recorded as split and no longer preventing ingress of dirt, resulting in major defects and a failure, though subsequent tests have since cleared that specific item. The 2026 test passed with no fresh defects beyond the recurring brake pipe advisory, suggesting the vehicle is currently roadworthy but carrying an unresolved chassis corrosion trend worth monitoring. With 130,996 miles spread over roughly 22 years of life, the annual accumulation works out at around 5,950 miles per year, which is notably low for a vehicle of this vintage. This figure implies either extended periods of low use or the kind of light running that suppresses wear on major drivetrain components but can accelerate deterioration of rubber seals, boots, and underbody protection through age rather than mileage. The MOT testing itself has been consistently annual since 2023 with no multi-year gaps in the recorded history, so there is no evidence of a long off-road lay-up that would necessitate the kind of dormant-vehicle reconditioning sometimes required after years of standing. For a prospective buyer, the brake pipe advisories warrant close physical inspection, as grease-covered corrosion noted in 2025 and again in 2026 on the offside rear is the type of finding that frequently progresses to pipe perforation within a short service interval. On a test drive, listen for any scraping or metallic noise from the rear undercarriage over bumps, and ask the seller to demonstrate firm pedal feel without excessive sponginess or travel. Although the CV boots were replaced or rectified after the 2023 failure, it is worth inspecting the inner and outer boots on both front shafts for fresh splits or grease fling, and on the road, listen for clicking or knocking on full lock or during sharp direction changes, which would indicate joint wear from contaminated grease. The 2025 advisories for tyres on both rear edges also suggest the rear alignment or tracking may be drifting, so verify even tyre wear across the rear axle and check for any steering pull or uneven handling. The anti-roll bar linkage ball joint play noted as an advisory in 2023 should be rechecked physically by rocking the wheel and feeling for any clonking over uneven surfaces, as anti-roll bar wear on SUVs of this age is common and often progresses quietly. Given the recurring nature of the brake pipe advisory and the age of the chassis, a thorough underside inspection on a ramp is strongly advisable, paying particular attention to the rear brake line runs, the fuel pipework, and any structural jacking points for corrosion that MOT testers do not routinely flag. Finally, given the low average mileage, confirm that the timing chain or belt interval is within manufacturer specification by date rather than by mileage alone, as age-related degradation of rubber drive components is a known consideration on low-use vehicles.
