A U.S. class-action lawsuit filed in Colorado against Toyota alleges the Japanese automaker hid problems that have led to a rash of recalls, attorneys said Thursday.

Attorneys at Burg Simpson Eldredge Hersh & Jardine said they had filed a lawsuit in Colorado federal court against Toyota Motor, on behalf of a Lakewood, Colorado, man.

The attorneys allege the company "has known for several years about the unexpected acceleration problems that recently led Toyota to temporarily stop selling and recall many of its most popular models in the United States."

The lawsuit seeks a monetary recovery for all Colorado residents who own the affected cars, they said.

A Canadian class-action lawsuit against the Japanese automaker was filed Monday over defective throttles that led to mass recalls.
