UNWANTED ACCELERATION, FLOOR MAT

What NHTSA is examining

The driver side floor mat will not interfere with the throttle pedal if properly secured using the retaining hooks provided by toyota.however, if the all weather mat is unsecured and moves forward from its intended position it can entrap the throttle pedal at the fully open position after it has been depressed.this can happen regardless of whether or not another mat (carpet) is underneath.when this occurs, some operators react by applying the brake pedal multiple times, depleting the braking system's (vacuum based) power assist.stopping the vehicle with unassisted braking while the throttle is fully open requires significant pedal force, which some operators did not, or were unable to, apply for the required duration.continued driving in this condition results in overheated brakes, which further diminishes the braking effectiveness.some operators attempted to turn the vehicle off by depressing the engine control button, however they were unaware the button had to be depressed for three seconds to stop the engine when the vehicle is in motion; this functionality was not explained adequately in the owner's manual.in odi interviews, owner's reported they were unaware the all weather mat had the potential to interfere with the throttle pedal, advising that this was never properly explained given the significant hazard it represented.owners reported several explanations for why the mat was unsecured, including that the vehicle was delivered in this condition (most common reason)…
