I was driving on a 16 lane major highway in toronto in the express lanes at 70 mph. Without warning the engine lost all power and stalled. The check engine light was flashing. It was difficult to stop safely since the power steering and power brakes were not functioning with the engine stopped. It would not restart and I was lucky to change lanes in heavy traffic and pull onto the hard shoulder of the road. I was stuck sitting in the express lanes by a guard rail until a tow truck came, which took an hour. After taking it to the Porsche dealer it was diagnosed as a ims bearing failure that required a new engine. I was also told this bearing is a common problem with the 1997 to 2008 water cooled 911 and boxster Porsches with a 10 percent failure rate to date, and that they will all fail eventually. The dealer also said there is a 3rd party retrofit kit that the Porsche dealers are aware of but don't use because it would acknowledge there is a problem with the car, so Porsche turned a blind eye and let the engines fail. Porsche has modified the bearing design several times before abandoning the design in the 2009 model year. All these models are unsafe when they will fail without notice and put drivers in harms way.
