Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2004 Porsche Boxster Owner Comments

Boxster 6-cyl

2004 Porsche Boxster, 58-60K mi, had catastrophic engine failure at 10 mi/hr. Engine stalled; was able to restart and drive a few feet, but badly missing. Loud clanging noise from engine. No smoke. Oil drained from car when tilted on towtruck. Dealer found intermediate shaft (ims) failure; required engine replacement at $18K. Dealer said they had seen a significant number of ims failures (but Porsche has not notified owners). 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. Defect found in MY97-08.
