Luxury vehicles which are possibly affected by engine problems will begin being recalled Monday, according to plans by Toyota Motor Co.. The company plans to submit documents Monday recalling 90,000 vehicles in Japan, according to Mieko Iwasaki, company spokesman. In other regions, recall announcements will be handled by each individual country.

Toyota is looking into engine problems affecting 270,000 vehicles across the globe, the company said Thursday. According to spokesman Paul Nolasco, there was low quality metal used to manufacture small valve springs, and these springs could crack, causing engines to potentially stall. Most drivers will experience only minor problems, such as engine noise or abnormal idling, and even that scenario was called a “remote possibility”.

The recall could potentially affect about 137,000 vehicles in the United States, according to Toyota. The models that are potentially affected include luxury sedans and hybrid cars, and the model numbers are the Lexus IS 350, GS 350, GS 460, GS 450h, LS 460, LS 600hL, GS 450h and the LS 600hL, the final two being the hybrids. The Toyota Crown, a large luxury model that is sold outside of the United States, could also be affected, according to Toyota, and only models from the year 2009 and prior could possibly involved.

To date, there have been no reports received by Toyota of any deaths or injuries relating to the problems, and Toyota’s luxury Lexus division plans to announce a solution for the problem as soon as possible, according to a company statement. In the words of Mark Templin, Lexus’ general manager in the United States, “In the meantime, we sincerely apologize to our customers for any inconvenience and request that they contact their nearest Lexus dealer if they believe there is a problem with their vehicle.” This is the latest in a long-running array of safety and quality problems with Toyota vehicles, as the company gas recalled more than 8 million vehicles across the globe in recent months, due to a variety of potential safety problems, including trouble with the anti-lock brake software, as well as potential unintended acceleration.

The most recent recalls involved some Lexus Sport Utility Vehicles, due to problems with the software controlling the electronic stability of the vehicle. The problems have not gone unnoticed either; in a recent JD Power and Associates survey of initial quality, Toyota went from 6th place last year, all the way to 21st place this year.
