Toyota warned its dealers as early as 2002 after receiving complaints from Camry owners about sudden acceleration problems. According to a CNN special investigation, the auto maker had recommended calibration and adjustments to the electronic control unit, at the time, to fix the problem. This technical service bulletin from the manufacturer apparently went to every U.S. Toyota dealership in 2002. The bulletin clearly stated: “Some 2002 model year Camry vehicles may exhibit a surging during light throttle input at speeds between 38-42 mph. The Engine Control Module (ECM) calibration has been revised to correct this condition.”
Over the last five months, the Japanese auto maker has issued vehicle defect recalls for more than 8.5 million vehicles due to faulty floor mats, defective gas pedals and brakes. But so far, there has been no mention of any computer glitches. This document dug up by CNN, on the other hand, does not make references to any mechanical issues such as gas pedals or floor mats.
