Lexus says about 137,000 vehicles in the U.S. could be affected by potential engine problems with cars produced by Toyota. They are among 270,000 cars sold worldwide that could stall while the vehicle is moving causing major accidents and serious injuries. Lexus says it has not received any reports of accidents or injuries related to the issue.

Lexus general manager Mark Templin says the affected vehicles have some contaminated materials used for valve springs in the engine, which could cause abnormal noises or rough idling. In extreme cases the engine could stall and drivers would likely hear noises or idling before the vehicle stalled.

Toyota is still dealing with fallout from its recall of 8.5 million vehicles because of sticking accelerator pedals and pedals that can get trapped in floor mats.
