When Toyota issued a major recall several years ago the original complaint from owners was a vehicle that would accelerate uncontrollably under it’s own power.
Toyota stipulated that the recall would only be justified if a certain cost threshold was reached in lawsuits.
Once that threshold had been met with wrongful death suits, Toyota issued the recall. The recall was supposedly to repair a faulty gas pedal and or floor mat situation. However, due to the volume of recalls needing to be performed Toyota opted to have independent repair facilities perform some of the recall procedures. The procedure itself was a simple software update and calibration issue dating back to the millennium 4 digit shift in software. Because it wasn’t written properly originally the vehicles could easily reset their own throttle calibrations and end up with a stuck throttle body. The result was millions of vehicles needing recall service, billions in cost, and lives lost.
