Things can’t get much worse for Toyota. The latest in a long line of problems with the once reliable brand’s cars may be a steering problem caused by the computer on 2009 and 2010 Corollas. According to USA Today, Corolla owners are complaining that their cars suddenly become hard to control at high speeds, pulling sharply to one side as if hydroplaning.

Toyota recently recalled some almost 500,000 Prius and Lexus HS250h hybrid sedans because of a braking issue caused by bad software. The Corolla’s steering problem may also be computer related. One owner who filed a complaint with the NHTSA said that his smartphone caused the steering wheel in his Corolla to act strangely, according to AOL Autos.

“I notice the steering wheel sometimes pulses only when my cell phone is…docked to the right of the steering wheel. It’s strange I can sometimes tell if my Blackberry is going to ring or get an email. The steering wheel seems to shake or try to steer on its own.”

Smartphones make both computers and land line telephones go haywire whenever they send or receive data, so it’s not completely bizarre to think that they might affect a car’s computer too. If these reports are true, Toyota should probably get a fix worked out soon to avoid having to recall 2009 and 2010 Corollas twice in a short time period.

As Autoblog points out, this problem could be just hysteria incited by Toyota’s recent recalls. This could also be another legitimate problem brought on by Toyota’s recent focus on volume over quality.
