What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The vehicle that hit me, hit the porsche directly in the driver's side, it ripped the side mirror off the porsche, blew out all the driver's side window glass, and severely damaged the driver's side door. The air bags did not operate or deploy and the door flexed and hit me (the driver) in the left side.
Was traveling on straight, smooth road about 55-60mph when coolant warning light came on and engine temperature rose without warning. I had no where to pull over on the two-lane road, so was forced to stop car in lane, putting myself and family at risk of being hit by traffic while we waited 4 hours for a tow.
Also, the engine can overheat with a replacement cost of over $20,000. Porsche is aware of this, as they have uses a superior threaded design on their race cars with this engine. I have been advised that this will take thousands of dollars to fix, and the car will be out of service for weeks.
I felt the car shake and decided to pull over. I discovered coolant leaking from under the car and the shake was caused by my rear tires slipping and traction control compensating for acceleration under slippery conditions.
Problem similar to [ref] incidents of sudden coolant loss which occurred while driving on public roadways well under highway speed limit (less than 60mph). The problem occur sudden with no way to avoid and check prior incident happen.
Sudden, catastrophic failure of coolant hose 996.106.502.74 by longitudinal split approximately 4" long. Coolant dumped on lr wheel caused loss of control and vehicle spin.
Water manifold has press-fit epoyy connections that have been known to come loose. Mine did and I lost all of my coolant. It blew across the whole engine bay and over back tires. Very dangerous as a car spun out of control behind me as well.
Last fall when light came on they said it was a control module and replacing it with a new one would cure it, less than 2,000 miles have been driven since that repair and car was stored for the winter, it has fail again and they are going to replace seatbelt, which has been done 4 previous times to no avail.
