The woes of Toyota are changing as fast as an unintentionally accelerating Prius. Recalls, Congressional Hearings, faulty floor mats, sticky accelerators. The Japanese automaker, the world’s largest, is in the midst of arguably the worst quality control and reputation nightmare in automotive history.Here’s a timeline of Toyota’s troubles, August 2009 to March, 2010:

* March 8 — Driver James Sikes speeds along a San Diego County freeway in a 2008 Toyota Prius for 20 minutes, reaching 94 miles per hour, before a Highway Patrol officer helps slow down the car. Toyota, the California Highway Patrol and federal safety officials say they will investigate.

* March 2 — U.S. Prius sales rise 10 percent in February despite earlier recalls over faulty brakes and floor mats that can trap gas pedals, causing unwanted acceleration.
