The ims bearings in the 2001-2005 porsche boxster would just stop the engine if not replaced. Hello, I bought my 2003 posche boxster brand new from rector porsche/audi dealership of burlingame back in 2003. I recently found out that porsche had a faulty part in their engine called the ims bearings. The cars that were involved are cars from 2001-2005 porsche boxster. There was a lawsuit (eisen vs. Porsche cars north america) that took place and settled before going into trial. People that owned the cars were notified to get their ims bearings fixed through porsche. I was never notified. I reached out to porsche cars north america and asked about the lawsuit. The last date to file to get your car fixed was october 15, 2013. They told me that I wasn't even listed in their system as the owner of my porsche boxster. So I asked. How could have I filed a claim if I was never notified about it. People's cars would seized from working without any signs of any problems. My car only has 32,480 miles on it. The dealership mechanic suggest's that I get my ims bearings replaced. But it would cost me $3,500. What can I do about this? They won't own up to this and it's their fault for not having my name listed in their system. I showed them my bill of sales from rector and even showed proof of registrations dating back from 2002 - to present day.

The intermediate shaft bearing when out and spread metal shaving throughout the engine. This caused a catastrophic engine failure. I have to have the car towed to the mechanic and will have to have an engine rebuild. The car has been service according to the company provided service manual. I called porsche USA to see if they woudl do anything about the failure, since this has been a documented problem with certain porsches, but the company would not help.

This low-mileage vehicle experienced a catastrophic engine failure at freeway speed. The vehicle was cruising on level freeway when the engine lost power and white smoke began pouring out of the exhaust. The engine died and would not restart on the side of the freeway and was towed to a service facility. After complete disassembly it was determined that the engine was not rebuild-able due to a slipped cylinder sleeve which resulted in piston, cylinder head and block damage. Detailed photos are available.

Traveling 75mph on freeway when oil & engine lights came on and vehicle simultaneously came to dead stop in traffic; diagnosed as catastrophic engine failure by dealer service mgr., engine replaced at cost of $17,000+. No prior warning. No fault of my own per svc.mgr. 38k miles on 2005 vehicle, 3 mo out of warranty. Many similar incidents reported on several web sites. Service mgr reported porsche well aware of this issue but does nothing because its too costly to repair and prefers to handle on case by case basis. Sometimes covers part of cost, sometimes nothing. Had I not been able to brake and coast to stop, I would have rolled over and most likely been killed! Damaged engine returned to porsche in germany. I have the part that broke from which little balls spewed throughout the engine. I am informed this occurs in approx. 20% of porsche boxsters and other porsche vehicles for several years until they redesigned the bolt in 2010 models. Unable to determine how many injuries and/or deaths resulting from these catastrophic engine failures because accidents would appear to be from driver error and no one would know the engine failed under these circumstances! Porsche employees are instructed not to acknowledge knowing anything about this being an ongoing issue and not to make repairs at porsche expense except for the customers who raise the biggest fuss. Another boxster was in the shop at the same time as mine for the same problem. The google address link below shows a photo of a boxster crankshaft and intermediate shaft. One of the connecting rods broke near the piston wrist pin end and the intermediate shaft is damaged. This catastrophic engine failure is the result of: 1) a seized connecting rod bearing, 2) a loss of oil pressure, 3) bad original component design, 4) intermediate shaft assembly failure (bolts or mechanical connection eg: weld, crimp). This is what happened to my car. Http://www.rx8club.com/showthread.php?t=160705.

My 2005 porsche boxster, 23k mi, had catastrophic engine failure at idle. The engine stalled;I was able to restart but a loud clanging noise came from engine. The car then died again. The mechanic said it was due to an intermediate shaft (ims) failure; the required engine replacement is $14k. The mechanic said he has heard of significant number of ims failures (but porsche has not notified owners). There were no injuries, but certainly engine failure like this could have serious consequences at freeway speeds. Porsche forums on internet show frequency of failures from this defect (poorly designed bearing assembly on ims) is very high, as much as 8-11% in one forum poll.
