The NHTSA has been investigating the recent Toyota recall issues that provoked unintended acceleration issues. It found that 35-58 percent of the cases were not down to electronic faults but down to the driver simply not applying the brakes.

Toyota first suggested the unintended acceleration issue was not down to an electrical fault, and out of the 6200 complaints, the NHTSA says 2000 of them were due to floor mat interference and driver errors. So although the mat getting caught under the accelerator pedal is an issue in itself, the car’s electronic circuitry, it seems, was not the sole cause of the problem as first thought.

Toyota has also been doing testing on some 4000 on-site vehicles and found no cases of the vehicle accelerating under some form of electrical fault. Still not putting an end to the issue though, the investigations will continue, even with the help of NASA, until a more definite result can be concluded.

Out of the 9.4 million vehicles recalled, 7.5 million of those were from America, where also, 89 reports of death had occurred due to the problem in some form or another.
