Another round of recalls has affected carmaker Subaru (FUJHY). The company is recalling an estimated 640,000 vehicles worldwide as part of an issue that causes stalling, as reported by the Associated Press.

The first recall from the company affects its Outback and Legacy vehicles sold in the U.S. under the 2018 model year. This will affect about 229,000 vehicles that have a software issue that stops the low-fuel warning light from illuminating, according to government documents. The can make the number of miles-to-empty inaccurate, creating a situation where a driver could run out of fuel and stall their vehicle, which may result in a crash.

The second recall from Subaru includes its 2012 to 2014 Imprezas and 2013 BRZ, XV Crosstrek, and Toyota Scion FR-S vehicles. Toyota and Subaru jointly developed the FR-S. This is a worldwide recall that affects approximately 411,000 vehicles. Engine valve springs in the recalled models can fracture, causing the engine to malfunction or stall.

Vehicle owners will start to be notified of the Subaru recalls in December, according to the outlet.

Consumers that own a vehicle that has the fuel indicator recall will receive a reprogramming of the software that is causing the stalling issue. If software reprogramming tools are not ready at the time of repair, owners will be notified when they will become available.

Consumers that drive the vehicles affected by the engine valve springs will have the parts replaced by a dealer. If valve springs are not ready at the time of repair, owners will be notified a second time when they can take their vehicle in for replacement of the parts.

Subaru has reported no crashes or injuries due to either recall issue, according to the Associated Press.

As of Friday afternoon, Subaru stock prices were down over 3 percent.
