2020 Lexus RX 3.5L Hybrid electric · LS20 AAZ

The Lexus RX’s most recent MOT history reveals a stable but unusual pattern, with the vehicle passing all tests since March 2023 without any recorded defects—until the March 2026 test, which failed for an unspecified reason despite identical mileage. The subsequent retest two days later passed without comment, suggesting either a minor oversight in the initial inspection or a temporary procedural issue rather than a mechanical trend. No advisories or recurring faults appear in the record, which is notable given the vehicle’s age and mileage. The lack of defects across five tests implies consistent maintenance, though the 2026 failure warrants verification of what was corrected. Mileage progression shows a steady but moderate accumulation, averaging roughly 8,800 miles annually—a typical rate for a luxury SUV of this age. The gap between tests remains consistent at one year, with no abrupt jumps or prolonged inactivity. For example, the vehicle covered 5,277 miles between March 2025 and March 2026, and another 5,265 miles between March 2024 and March 2025, suggesting regular use without extreme wear patterns. The absence of mileage gaps larger than a year also indicates the vehicle was likely in service rather than stored. Given the clean MOT record, a buyer should prioritise a thorough inspection of high-wear components that often fail silently or exhibit gradual degradation. Focus on the suspension system—particularly the rear coil springs and bushes—for signs of uneven wear or corrosion, as these can develop issues over 50,000 miles without immediate MOT failings. The brakes, while not flagged, should be checked for uneven pad thickness, binding calipers, or corrosion on the rear discs, especially if the 2026 failure involved braking performance. Structural integrity is less likely a concern given the lack of advisories, but a close examination of wheel arches, sills, and underbody for rust or damage is advisable. Finally, verify the exhaust system for leaks or excessive corrosion, as emissions-related failures are common in luxury vehicles at this mileage.
