Own a 2010 Subaru Forester? Live in California? You might fail emissions tests if a software update isn’t installed.

The Wall Street Journal had this to say about the issue:

Q: I own a 2010 Subaru Forester and just received a letter from the Subaru of America Inc. that said: “Subaru has developed a modification to the Engine Control Module software logic that will improve the performance of your vehicle’s emission control system.” The letter went on to say that this software update is intended to improve vehicle emissions when the vehicle is operated in cold weather and the engine is restarted within short periods of time. They’re asking me to take my vehicle to the dealership to have the Engine Control Module reprogrammed. Is it necessary?

—Mrs. P. Casey, Colorado Springs, Colo.
A: Subaru sent recall notices out for the Forester because of an engine-control problem that could keep the catalytic converter, which helps clean the car’s emissions, from operating efficiently. The problem could result in vehicles failing to meet California emissions standards, but should be addressed in cars elsewhere as well. The dealer should make the fix free of charge.
