2015 Lexus GS 3.5L Hybrid electric · E2 ARU

Recurring braking system issues and recent tyre-related safety failures define the mechanical profile of this Lexus GS. The vehicle's recent history shows a period of instability, moving from a dangerous failure in January 2024 due to insufficient tread depth on both rear tyres to a major failure in early 2026 regarding parking brake efficiency. While the most recent test on 10 January 2026 resulted in a pass, the record shows a persistent trend of brake disc wear, with advisories for both nearside and offside rear discs being worn and lipped on the edges. This indicates that while the parking brake efficiency was addressed to meet requirements, the underlying wear on the rear braking components remains an ongoing concern. The vehicle has covered 147,361 miles over its eleven-year lifespan, representing an average annual accumulation of approximately 13,396 miles. This usage pattern is relatively high for a vehicle of this age, suggesting consistent long-distance or frequent road use rather than short, sporadic trips. From a mechanical perspective, this level of mileage typically correlates with increased wear on consumable components such as suspension bushes, dampers, and braking hardware. The high mileage combined with the recorded failures suggests that components are being used heavily and may be approaching the end of their functional service life. A prospective buyer should pay close attention to the rear braking assembly during a test drive. Given the history of parking brake efficiency failures and the current advisories regarding worn and lipped rear brake discs, it is essential to test the handbrake's holding strength on an incline. During road testing, listen for any grinding or squealing noises from the rear wheels and feel for any pulsation or judder through the brake pedal when applying the service brakes. Any unevenness in braking force or a pulling sensation could indicate that the discs or calipers require more than just superficial attention. Further inspection should focus on the rear tyres to ensure they have been replaced following the dangerous failure recorded in 2024 and that they meet current legal tread depth requirements. While the recent MOT did not flag tyre defects, the previous failure highlights a need to verify the quality and remaining life of the rubber. Additionally, because of the high mileage, a thorough check of the suspension components is advised; listen for knocks or clunks when driving over uneven surfaces or speed bumps, which may indicate worn bushings or dampers that have been subjected to the vehicle's high annual mileage.
