Subaru and Toyota are recalling some 410,000 vehicles following the discovery of a faulty valve spring that could cause engine failure.
The last model affected is the Subaru-manufactured Toyota’s 86 sports car, sold as the Scion FR-S in 2012 and 2013.
The remaining 310,000 vehicles were sold overseas: about 160,000 in North America, and 100,000 in other areas, including Europe. The remaining 50,000 were Toyota’s 86 that were released overseas; of these, 25,000 are being recalled in the United States.
Owners affected by the recall will receive notice via mail starting in December. The repairs could take over 12 hours per vehicle.
Valve springs are responsible for keeping engine valves closed when the car burns fuel. Subaru and the Japanese Transport Ministry said that that excessive pressure on a potentially faulty valve spring in the engine may cause the engine to break and stop the vehicle, thereby increasing the risk of accidents.
There have been no reports of accidents caused by the faulty engines, but Subaru has recorded 224 reports of engine complications since April 2012. Ninety-four of the reports were made in Japan.
Subaru explained why the company waited five years to announce the recall:
“After we received reports that the engine part had broken, we used an improved one based on a certain presumption. But it took time to clarify why the engine part had broken,” the company said, according to the Asahi Shimbun.
A Separate Toyota Recall
On the same day as the Subaru recall, Toyota announced a separate recall of its Scion xA vehicles. The voluntary recall concerns an airbag issue that will affect about 17,000 vehicles manufactured between 2004 and 2006, Newsweek reported.The company will notify owners of the vehicles via mail starting late December. Vehicle owners can come into Toyota dealers to replace the airbag control units with an improved model, free of charge.
The recall explains that an electrical short could damage the circuits to the airbag system, according to Newsweek. This could cause two potential problems; it could cause the airbags to deploy, and may also cause the seat belt pretensioner to deactivate. This extra seatbelt pretension pulls the bodies of the driver and front-seat passenger firmly into their seats, moments before impact in an accident. Both scenarios can increase the risk of accidents.
