(CNN) -- A preliminary report from a consulting firm hired to analyze Toyota and Lexus vehicles linked to unintended acceleration failed to find any problem with the carmaker's electronic throttle controls, Toyota announced Saturday.

Toyota said it had retained Exponent, an independent engineering and scientific consulting firm, to conduct the analysis of its vehicles that use the suspect Electronic Throttle Control System with intelligence.

"The interim report, dated February 4, 2010, notes that Exponent was unable to induce unintended acceleration in any of the ETCS-i equipped Toyota and Lexus vehicles it tested," the company said in a posting on its Web site. "In all cases, the vehicle either behaved normally or entered a fail-safe mode where engine power was significantly reduced or shut off."
