Tesla Motors is in a bit of trouble as a Model S owner sent a complaint to NHTSA concerning unintended acceleration issues.

It's been a while since we last used the "unintended acceleration" phrasing, following the huge scandal concerning Toyota from a couple of years ago. Now, the National Highway Traffic and Safety Administration received a complaint on Tuesday about a similar issue in a Tesla Model S.

The story sent to NHTSA speaks about the wife of the car's owner who was travelling down a short driveway at around 5 mph while consistently applying the brakes. At one point, the vehicle suddenly accelerated, hit a curb and then ended up on a 4.5 ft. retaining wall approximately one foot from the curb.

One of Tesla Motors' engineers said the records showed the Model S' accelerator was pressed and in a split second the pressure jumped from 18 percent to 100 percent. Tesla blames the driver for this incident and mentions the car has a safeguard which doesn’t allow the accelerator to exceed 92 percent. However, this is a contradicting fact since the records showed a 100 percent accelerator pressue.
