2011 Infiniti G 3.7L Petrol · YK61 AWH

The Infiniti G holds a current MOT pass recorded on 8 April 2026 at 80,082 miles, but the underlying maintenance trend is deteriorating rather than stable. Six days earlier, on 2 April 2026 at 80,068 miles, the vehicle failed on rear tyres below the 1.6mm legal limit, an excessively corroded offside front brake pipe, and carried forward worn brake discs and front sub frame corrosion. The subsequent pass cleared the tyres and brake pipe but left advisories for nearside rear anti-roll bar ball joint play, front tyres worn on edges, pitted front and rear brake discs, and front sub frame corrosion. Recurring brake disc pitting dates back to the 17 March 2023 test at 68,912 miles, showing a long-standing refusal to renew consumable friction surfaces. Anti-roll bar linkage wear first appeared in the 12 March 2024 test at 72,628 miles and has progressed to ball joint play by 2026. Mileage accumulation across the record is consistently low for a fifteen-year-old vehicle. The odometer advanced from 68,912 miles in March 2023 to 72,628 in March 2024, then 76,547 in March 2025, and 80,068 by April 2026, averaging roughly 3,700 miles per year. No unexplained gaps exist between annual tests, and the fault list outside tyres and corrosion suggests careful storage but intermittent mechanical neglect. The low yearly distance implies lighter use, yet standing periods likely contributed to the newly surfaced sub frame and brake pipe corrosion. A buyer should prioritise a physical inspection of the front sub frame and offside front brake pipe for structural integrity and corrosion depth, as both pose serious mechanical risk beyond consumable wear. The tester flagged the front sub frame corroded in April 2026; this demands scrutiny for perforation or load-bearing compromise. Brake discs front and rear remain worn, pitted or scored since 2023, so measure disc thickness and check for scoring. Suspension requires attention: the nearside rear anti-roll bar ball joint shows slight play and earlier linkage bushes wore without excessive movement, indicating ageing rubber components. Verify steering rack inner joints, last noted with play in March 2023, have been rectified. Front tyres worn on edges suggest alignment or camber issues. The failure on rear tyre tread proves the previous owner deferred basic upkeep, so expect deferred maintenance elsewhere.
