The problem, however, isn't with anything electronic or mechanical. Instead, it's the unsecured or incompatible floor mat issue, which can entrap the accelerator pedal and cause the vehicle to accelerate. If it seems strange to you that something so simple could be such a big problem, you're not alone.
Owners of affected vehicles will receive notification from Toyota early in August. A fix for the problem will be carried out at Lexus dealers at "no cost to the customers." No cost, that is, aside from the lost time at the dealership.
While the floor mat issue is a real one, and could surprise drivers, creating dangerous situations, the reality is that most vehicles even without brake override systems to electronically slow the engine will still slow significantly with the brakes applied--even with a stuck or entrapped accelerator.
