Last year my 2010 Porsche 911 GT3RS experienced a catastrophic engine failure while on the road. I had to shut off the car in the middle of a 4-lane highway and try to coast to a stop while navigating around much faster traffic risking my safety and the safety of other drivers. There was no warning prior to the failure. Just a sudden bang, followed by shaking and rattling noise. Once the car was towed to an automotive repair shop, the engine was taken apart and it was concluded that a piece from the intake broke off and got swallowed by the engine while on the road. I have images and documentation of the damage and the parts are available for inspection. The trouble is that the failed piece of the intake was part of a manufacturer recall to fix that exact issue back in 2013. After the findings of the repair shop I contacted Porsche Cars North America. The car was subsequently brought in to a Porsche dealer for inspection, where I was told multiple times that a failed recalled part would be covered by the manufacturer's good will repair policy. After 4 months of back and forth with the headquarters I was told that Porsche would not be responsible. I have spoken to other owners of this exact model cars and several of them have confirmed that their replacement intakes have failed, in some cases causing the engine to completely seize while on the road. Thankfully that did not happen to me.
