$1 million offered to anyone who can show why Toyotas accelerate unexpectedly.

Edmunds.com, the auto information and pricing company, is launching a public competition to find the cause of and solution to the problem that has allegedly caused dozens of auto accidents.

The National Highway Traffic Safety Administration (NHTSA) has received at least seven complaints from Toyota owners who say they are experiencing unintended acceleration even after their cars have been repaired as part of Toyota’s floor mat and accelerator pedal recalls.
