Problems detected with Lexus cars

A total of 480 Lexus cars here have been found to have engine problems.

The models affected are the current generation LS 460, LS 600h and GS 450h.

Parent company Toyota says a fault has been discovered in some valve springs, and there is a chance it could stall the engine.

At the end of last year, Toyota was forced to order a huge recall of its cars over problems with accelerator pedals.
