Lexus is launching two voluntary recalls for brake and fuel pump problems on its IS, GS and RX models with 17,481 cars affected in the UK.

The first recall affects 15,400 models and concerns the brake master cylinder fitted to IS, GS and RX models built between February 2003 and November 2005.

The carmaker said: “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.

The second recall concerns the fuel pump on GS 300 models built between September 2004 and February 2006.

Lexus said: “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.

Belinda Poole, Lexus managing director, said: “We apologise for any inconvenience or concern these recalls may cause our customers.

“Our Lexus centres will be liaising with our customers to carry out the recall repair procedures as promptly as possible, with all work undertaken by expertly trained Lexus service personnel.”
