Toyota is recalling nearly 2.2 million more cars to fix problems related to floor mats that can trap gas pedals and cause vehicles to accelerate uncontrollably. Among the models being recalled: The Toyota RAV4, 4-Runner and Highlander, and the Lexus LX 570, RX 330, RX 350 and and RX 400h.
The carmaker hoped findings from two federal studies would put to rest speculation about its electronics system as a source for unintended acceleration. But the results may not prove enough to give Toyota a leg up in its ongoing legal battles.
In an affirmation of Toyota's claims, an exhaustive 10-month federal investigation has found no evidence of an electronic source for sudden unintended acceleration in companpy's vehicles. Indeed, human error was cited as the cause in many cases.
Last year's massive recalls -- and the resulting legal fallout -- have given Toyota's reputation a beating, cutting into its sales. But the company can't blame all of its problems on the recalls. Analysts also point to another issue: A lack of compelling new models.
Automakers recalled more vehicles last year than in any of the last six years. And while Toyota Motors accounted for much of the growth, with problems including unintended acceleration and glitchy brakes, many other car manufacturers also saw their recalls increase.
The beleaguered Japanese carmaker is sending notices to Sienna owners to warn them of brake-light switch brackets that are susceptible to damage and could lead to eventual loss of braking effectiveness. No accidents relating to the defect have been reported.
