2021 Lexus RX 3.5L Hybrid electric (clean) · CK21 ABO

A single advisory for rear‑side rear suspension arm wear dominates the mechanical picture of this 2021 Lexus RX; the car has otherwise cleared three consecutive MOTs, most recently on 11 April 2026, where it passed without any recorded failures. The lone advisory recorded on 1 May 2024 noted a worn pin or bush on the off‑side rear suspension arm, but judged not to be causing excessive movement, and no further defects have been added since then, indicating a stable, if not entirely pristine, condition of the inspected systems. At 37 889 miles the vehicle averages roughly 7 600 miles per year, a mileage rate that sits squarely within normal private‑use expectations for a five‑year‑old executive SUV. The MOT history shows regular annual testing with no gaps, suggesting the odometer reading is consistent with the recorded usage and that there have been no periods of prolonged inactivity that would raise concerns about fluid degradation or component seizure. When inspecting the rear suspension, pay particular attention to the off‑side rear arm bush and its mounting pin. On a low‑speed drive over uneven surfaces listen for any clunking or thudding that may indicate progressive wear, and feel for lateral play when applying firm braking or steering inputs. Uneven rear tyre wear, especially on the outer edge of the off‑side tyre, can also be a symptom of a deteriorating bush. A visual check of the bush for cracks, oil staining, or excessive movement when the wheel is rocked will help confirm its condition. The child‑seat advisory from the 2026 MOT does not affect the mechanical integrity of the vehicle but does mean the adult seat belt on the passenger side could not be fully inspected; a quick visual check of that belt for fraying, corrosion or improper retraction is advisable. With no other recorded defects, the car’s primary mechanical risk lies in the rear suspension component flagged in 2024, and a focused examination of that area, coupled with a test‑drive for any abnormal noises or handling characteristics, should give a prospective buyer a clear indication of any imminent remedial work required.
