2006 Lexus RX350 3.5L Petrol · GP06 DTY

The most recent MOT on 18 June 2024 was passed, but it was accompanied by a suite of advisories covering a minor exhaust leak, thin rear brake pads, rear brake disc surface wear, and corrosion on both front and rear brake pipes. Earlier tests show a progression from a single parking‑brake efficiency failure in 2018 to the current spread of brake‑related issues and a front suspension bush wear note in 2022, indicating that the vehicle’s maintenance condition is trending towards a higher level of wear rather than improving. While no outright failures have been recorded since the 2018 failure, the accumulation of multiple advisories suggests that components are approaching the end of their service life and will likely require remedial work in the near term. At 166,081 miles recorded for a 2006 model, the vehicle averages roughly 8,300 miles per year, which sits comfortably within normal UK usage patterns for a car of this age. The mileage does not point to excessive wear from high mileage, but the relatively modest annual distance could also imply periods of prolonged inactivity, which can exacerbate corrosion of brake lines, rubber seals and battery plates. There are no obvious gaps in the MOT record, and the mileage progression appears steady, so the primary concern is the condition of wear items rather than hidden high‑kilometre abuse. A prospective buyer should give the braking system the highest priority. Inspect the rear brake pads for remaining thickness – they are already described as thin and will need replacement soon – and examine the rear discs for scoring or pitting that could cause vibration or reduced stopping efficiency. The corroded brake pipes should be checked for rust penetration or leaks; any fluid seepage around the pipe fittings will manifest as a spongy pedal or a faint brake‑fluid smell. During a test drive listen for any clunk or squeal when applying the brakes, feel for pedal travel consistency, and verify that the parking brake now holds the vehicle securely. The minor exhaust leak may produce a faint ticking or hissing at idle and could affect emissions; a visual inspection of the exhaust manifold and flexible joints for cracks or rusted joints is advisable. Front suspension bush wear noted in 2022 should be confirmed by checking for any knock when the wheel is rocked and by feeling for looseness in the lower control arm; worn bushes can lead to uneven tyre wear and compromised handling. Given the vehicle’s age, time‑based maintenance is as important as mileage‑based wear. Verify the condition of the 12‑volt battery – a load test will reveal any loss of capacity that often accompanies long periods of standing – and inspect the battery terminals for corrosion. Examine all rubber hoses, especially coolant and brake lines, for cracking, hardening or swelling, as age can render them brittle regardless of mileage. The cooling system should be flushed and the coolant replaced if it shows any discoloration or sediment, and the brake fluid, which typically requires replacement every two years, should be checked for moisture content. Finally, confirm that the service book shows regular oil changes, a recent transmission‑fluid change (the RX350’s automatic gearbox benefits from a fluid change around 100 000 miles), and that any recall work for the model year has been completed. A thorough visual under‑car inspection for rust on the chassis, sub‑frame and suspension mounts will also help gauge how the vehicle has fared during any extended storage periods.
