2005 Suzuki Grand Vitara 1.6L Petrol · HT54 AAZ

A pattern of front suspension wear and underbody corrosion advisories on a 21-year-old Grand Vitara with low annual mileage suggests a vehicle that has spent considerable time stationary, allowing rubber and protective coatings to deteriorate rather than suffering wear from sustained driving. The most recent test on 2025-12-02 was a pass, but it carried an advisory for a minor exhaust gas leak at the front section, following a clean pass in November 2024 and a 2023 test that flagged both an oil leak and a missing rear exhaust section. The 2022 test sequence is the more telling part of the record, with a fail issued just two days before a subsequent pass. The failures recorded on 2022-11-30 were substantial: an ABS warning lamp indicating a system fault, a parking brake that was inoperative on the nearside and fell below the required efficiency, and a split nearside front outer CV joint boot allowing dirt ingress. When the vehicle returned on 2022-12-02 it passed, but four advisories were raised covering both front lower suspension arm ball joints showing slight play, worn anti-roll bar D bushes on both sides, and structural corrosion on the underside of the main rail at a front body location. The overall trajectory is therefore one of a vehicle that has accumulated corrosion and suspension component deterioration consistent with age, with a recent stabilisation but no evidence of improvement in the underlying wear pattern. Recorded mileage of 115,506 miles across 21 years equates to roughly 5,500 miles annually, which is notably low for any vehicle of this age and particularly so for an SUV of this size. This usage profile typically reflects extended standing periods rather than light regular use, and standing time has a specific mechanical consequence for the components flagged during testing. Rubber items such as the suspension arm ball joints, anti-roll bar bushes, and CV joint boots deteriorate through oxidation and drying out rather than through mileage-driven wear, which aligns directly with the advisories recorded on both front lower arms, the D bushes, and the failed CV boot. The annual accumulation rate appears broadly consistent across the test entries, with no large gaps that would suggest a multi-year lay-up, but the low rate itself is sufficient to explain the type of component degradation observed. For a prospective buyer, the underbody corrosion advisory at the main rail body mount warrants close physical inspection, as advisories of this nature can progress between tests and a subsequent examiner may classify the same area as a fail if structural rigidity becomes significantly reduced. A thorough check on a ramp or over a pit is advisable, paying particular attention to the front floor area, chassis rails, and any boxed sections where moisture collects. On the test drive, listen for clonking or knocking from the front suspension over uneven surfaces, which would indicate progression of the ball joint play beyond the slight movement previously recorded, and feel for any vagueness or knocking through the steering that could point to further deterioration of the anti-roll bar bushes. The brake pedal should be tested both in operation and at rest, with the handbrake specifically checked for its ability to hold the vehicle on an incline, given the 2022 failure where the parking brake was inoperative on one side and overall efficiency fell below requirements. The ABS warning lamp fault recorded in late 2022 also requires confirmation that it has been properly resolved rather than simply extinguished, as intermittent ABS issues on vehicles of this age frequently relate to wheel speed sensors, reluctor rings, or hydraulic unit faults that can recur. The recorded oil leak, while noted as not excessive in 2023, should be monitored by checking the underside for fresh residue and the oil level between services. The exhaust system has now had advisories at three of the last four tests covering both front and rear sections, so a listen for escaping gases under load and a visual check of all joints and the catalytic converter area are worthwhile. Finally, with the 2022 test noting the vehicle was presented with rear seats folded as an animal transport area, a buyer should confirm that all rear seatbelts and seating components are present, properly anchored, and functioning, as this is a safety-critical system that was not inspected at that test.
