Slightly above average warranty repair costs in 2003 Warranty Direct Reliability index (index 107.78 v/s lowest 31.93)due to high cost of individual repairs. Average warranty repair costs in 2003 Warranty Direct Reliability index (index 101.16 v/s lowest 31.93). Link:- www.reliabilityindex.co.uk
Seem to get through front tyres quite rapidly despite being rear drive.
See above problem areas. Check gearbox and clutch action carefully before buying a manual. Check radios on independent imports.
3-2-2011: Seem to suffer from severe tyre wear because soft bushes in the front suspension deteriorate and while the alignment may read okay static, once the car is on the road the front tyres toe out excessively and wear their inner edges. Happens with standard 215/45 R17s. Worse with bigger, lower profile aftermarket wheel and tyre combinations.
16-11-2011: On 2000-2003 4-speed Toyota and Lexus auto boxes with overdrive there is a fault that can appear of the ecu causing rough changes that damages the gearbox and eventually breaks it. USA Toyota helped owners out with repairs no such help apparent here. ECU are £1,000. Transmissions much more.
20-10-2010: Lexus is launching two voluntary recalls in the UK, affecting its IS, GS and RX models. It is working with the Vehicle and Operator Services Agency (VOSA) to contact registered owners and keepers by letter to advise them of the procedure for taking their vehicle to a Lexus Centre or an Official Lexus Service Outlet for the necessary repair work to be done. The first recall concerns the brake master cylinder fitted to IS, GS and RX models built between February 2003 and November 2005. Lexus is aware that the seal between the brake master cylinder and the brake booster may turn in its seat, causing brake fluid to leak into the brake booster. In the very unlikely event that this happens, the driver will be alerted to the problem by the low brake fluid warning light. The brakes will continue to function normally for a significant time - over 200 miles of regular driving. Lexus knows of no accidents caused by this issue. The repair involves the replacement of a small seal and a check for any fluid contamination in the brake booster. If any contamination is found, the brake booster will be replaced. The job will take approximately two hours to complete, at no cost to the customer. Approximately 15,400 UK registered vehicles are affected by this recall.
The second recall concerns the fuel pump on GS 300 models built between September 2004 and February 2006. Expansion and contraction of the fuel tank may stretch the fuel pump’s electrical harness. This may lead to a break in the circuit, causing the fuel pump, and so the engine, to stop without warning. Lexus knows of no reported accidents as a result of this issue.
The repair involves replacement of the fuel pump wiring harness, a job that takes about three hours. The work will be done at no cost to the customer. The recall affects 2,081 UK-registered cars.
