Timeline: Toyota acceleration complaints
The DOT said that NASA engineers "found no electronic flaws in Toyota vehicles capable of producing the large throttle openings required to create dangerous high-speed unintended acceleration incidents."
- March 29, 2007: NHTSA opens a preliminary investigation into pedal entrapment on MY'07 Lexus ES350 models based on five consumer complaints alleging three crashes and seven injuries. The all weather floor mat is identified as the possible cause of these incidents.
- July 26, 2007: A fatal crash occurs in San Jose, CA involving a '07 Camry in which the driver suffers serious injuries and the driver of the struck vehicle is killed. The incident also appears to have been caused by a pedal trapped by an all weather floor mat.
- September 13, 2007: After determining the fatal San Jose crash was caused by floor mat entrapment, NHTSA tells Toyota a recall is necessary.
- September 26, 2007: Toyota recalls 55,000 floor mats in '07 and '08 Camrys and ES350s.
- August 28, 2009: A fatal crash occurs in Santee, CA, involving a loaner '09 ES350. The vehicle is found to have an all weather floor mat from another Lexus vehicle. Investigators find that the vehicle's previous driver had reported an entrapment incident to the dealership.
- September 25, 2009: NHTSA meets with Toyota and tells the company that the floor mat recall is insufficient and the agency expects a recall for the defect in pedal design. Three days later, Toyota tells NHTSA the company will recall the gas pedals.
- October 5, 2009: Toyota recalls 3.8 million vehicles for pedal entrapment by floor mat and sends an interim letter to consumers telling them to remove floor mats. The defect remedy involves gas pedal reconfiguration, floor pan/carpeting revisions, and 'brake pedal override' software for vehicles with keyless ignition.
- December 15, 2009: NHTSA officials meet with Toyota executives in Japan to explain NHTSA's defect recall process and underscore Toyota's obligations under U.S. law to find and report defects promptly. Toyota commits to making improvements.
- January 16, 2010: Toyota informs NHTSA that certain CTS-brand pedals may have a dangerous 'sticking' defect. NHTSA calls an in-person meeting on January 19.
- January 19, 2010: At the meeting, Toyota provides field reports on sticky pedal incidents, and NHTSA tells Toyota the agency expects prompt action. Toyota informs NHTSA several hours later that the company will issue a recall.
- January 21, 2010: Toyota recalls 2.3 million vehicles for the sticky pedal defect.
- January 27, 2010: At NHTSA's urging, Toyota expands its pedal entrapment recall to cover an additional 1.1 million vehicles.
- February 16, 2010:NHTSA launches an official probe into the timeliness and scope of the pedal entrapment and sticky pedal Toyota recalls.
- March 30, 2010: At the request of Congress, the U.S. DOT announces two studies into unintended acceleration. One looks at possible electronics causes for unintended acceleration in Toyotas; the other examines unintended acceleration and the safety of vehicle electronics across the automotive industry.
- April 5, 2010: NHTSA demands the maximum, $16.375 million, civil penalty on Toyota for its failure to notify the agency of the sticky pedal defect for more than four months after discovering it. Auto manufacturers are legally obligated to notify NHTSA within five business days of determining that a safety defect exists. Toyota pays the full fine on April 19.
- December 20, 2010:Toyota agrees to pay the maximum $16.375 million civil penalty as the result of another NHTSA investigation into whether their recall of 5.5 million vehicles for pedal entrapment was conducted in a timely manner.
