Porsche tells 911 GT3 owners to park their cars over engine fires

In any given year, automakers issue hundreds of recalls for safety defects on their vehicles. In a few rare cases, the defect can be so dangerous than an automaker will tell owners to stop driving and have their car towed to a dealership rather than risk saying on the road. Today, another such order arrived from an unlikely source: Porsche, which is struggling to find why its $120,000 911 GT3s are setting themselves on fire.
