Engine has cutoff on 3 occurrences: (1) operating the vehicle on the freeway at 70 mph and experienced immediate loss of power. I was able to manuever the vehicle to the shoulder while coasting without engine power. I was able to start the engine but it cutoff a few seconds after. The vehicle had to be towed to an independent Porsche repair shop where the high pressure fuel pump was replaced. (2) the engine cutoff while operating on city street at 40 mph. I was able to manuever the vehicle while coasting without power or power steering into a parking lot. The engine would start but cutoff a few seconds later on multiple attempts. The vehicle has to be towed to the same independent Porsche repair shop where the high pressure fuel sensor was replaced. This occurrence was the first time operating the vehicle after returning home from the high pressure fuel pump replacement service. (3) operating the vehicle while stopped at an intersection at a red light. When attempting to accelerate the engine cutoff and I was stalled for about 1 minute blocking traffic. I was able to restart the engine after a few attempts and drive the vehicle the remaining 2 miles home without incident. All 3 occurences involved abrupt engine cutoff and loss of power steering. The Porsche independent repair shop is unable to pinpoint the issue. The risk exposure to accident is high when engine cutoff occurs while the vehicle is in motion.
I purchased a 2008 Porsche Cayenne on 3/14/18. Here we are 3 months later and I noticed a strong gas smell coming from the driver rear tire. I used google to diagnose my concerns and found this: September 25, 2017 � Porsche is recalling more than 50,000 Cayenne suvs because the fuel pump filter flanges could leak gas and at the least create an odor of fuel, and at the most create a fire hazard if fuel hits a hot ignition source. The recalled gas-powered vehicles include the 2003-2006 Cayenne s and Cayenne turbo, 2004-2006 Cayenne and 2006 Cayenne s "titanium" edition vehicles. So, I took my car to get diagnosed at dean mcreary Porsche in mobile, al and was advised that I have a flange and sealing ring leak and that it would be 1124. 00 to repair. I am having the same problems described in this recall. This is a hazard. Someone could die. I then called Porsche north american and they informed me that the recall is VIN specific and I do not qualify. This makes no sense and they should be held responsible for repairs. Porsche is constantly making cars that are unsafe and when a problems occurs, they do not want to fix it.
The high pressure fuel pump, car drove with very little ability to speed up. It sputters when trying to accelerate. It won't start right away, building up fuel pressure. I was driving and it just became unresponsive to the gas peddle. I slowed and stopped, restarted and just had a very weak car. It takes some time to reach 50mph. Dangerous if on the hwy.
