2020 Lexus RX 3.5L Hybrid electric (clean) · LS20 UGP

The most recent MOT test on the 2020 Lexus RX, conducted on 2026-06-26, resulted in a passing outcome, though it included two advisories regarding the offside and nearside rear tyres showing signs of cracking or perishing in the outer sidewall. This follows a notable failure in 2026-06-22, where the nearside rear tyre exhibited a deep cut exceeding legal limits, reaching the ply or cords—a severe defect that would compromise tyre integrity and road safety. The previous two MOTs in 2025 and 2024 were clean, suggesting a pattern of stability prior to the recent deterioration. However, the recurring advisories on tyre condition indicate a persistent issue that has not been fully resolved, warranting closer attention to tyre health and potential underlying causes such as uneven wear, improper alignment, or excessive load distribution. The vehicle’s overall maintenance trend appears stable until the 2026 failures, after which it has not fully recovered, leaving the buyer with a critical defect to address before proceeding. The recorded mileage of 29,145 miles for a vehicle aged six years represents a relatively low annual usage rate of approximately 4,858 miles per year, which is notably lower than the industry average for a car of this age and class. Such low mileage can stem from either light usage, long periods of stationary storage, or a combination of both. However, prolonged idling or infrequent operation can accelerate wear on certain components, particularly those prone to corrosion or fluid degradation, such as brakes, suspension linkages, and electrical systems. The suspension, for instance, may exhibit signs of rust or binding if the vehicle has been left stationary for extended periods, potentially leading to uneven tyre wear or clunking noises during cornering. Additionally, standing fluids like brake fluid and coolant can degrade over time, risking system failure or reduced performance, especially if the vehicle has not been driven regularly. While low mileage is generally favourable for wear and tear, it does not negate the need for thorough checks to ensure structural integrity and prevent hidden issues exacerbated by inactivity. Given the MOT history, the primary concern for the buyer is the severe tyre failure recorded in June 2026 and the ongoing advisories on tyre condition. The nearside rear tyre’s cut reaching the ply or cords is a major defect that must be addressed immediately, as it poses a significant safety risk and could lead to sudden blowouts or loss of control. The buyer should replace this tyre with a new or high-quality reclaimed tyre that meets current legal standards, ensuring the cut is fully repaired or the tyre is discarded. For the advisories on sidewall cracking, the buyer should inspect the remaining tyres for similar damage, checking for signs of dry rot, delamination, or internal cord exposure, which can compromise tyre safety. During a test drive, listen for unusual noises from the rear tyres, such as a hollow or thudding sound when cornering, which may indicate uneven wear or internal tyre damage. Additionally, ensure the vehicle is driven at moderate speeds to avoid sudden stress on the tyres, and avoid prolonged periods of stationary use without regular movement to prevent further deterioration. In the absence of other major defects, the buyer should conduct a comprehensive physical inspection of the vehicle to address potential issues arising from its age, mileage, and usage profile. Focus on the tyres, checking for sidewall cracking, perishing, or uneven wear patterns that could indicate alignment or suspension problems. Inspect the brake system for signs of corrosion on discs or binding calipers, which are common in vehicles that stand for extended periods, as standing fluid can cause rust and reduced braking efficiency. Verify the condition of the suspension components, including coil springs, shock absorbers, and suspension bushes, for signs of wear, leaks, or excessive play, which may result in clunking noises or poor ride quality. The 12-volt battery should be tested for charge capacity and overall health, as low usage can lead to sulphation or internal failure. Lastly, since the vehicle has not undergone a full service in recent years, consider checking the service book for any scheduled maintenance, such as fluid top-ups, filter replacements, or timing belt inspections, which are critical for longevity. For fluids like brake fluid and coolant, assess their condition based on their age—brake fluid should be replaced every two years or 40,000 miles, while coolant should be changed every five years or 60,000 miles—regardless of mileage, as standing fluids degrade over time.
