Tesla Motors, an Elon Musk Production presents a recall of Model X minivans and Model S sedans over a parking brake manufacturing flaw which may lead the parking brake to fail to disengage. When this manufacturing flaw is realized the affected vehicle's parking brake engages and due to mechanical failures can not be disengaged without repairing broken components. As Tesla abandoned implementing parking pawls in their automatic transmissions following misadventures with the widely adopted technology in initial Roadster model, Tesla vehicles have relied on the parking brake alone to secure them in a stationary position.
