Very reliable; a few negative take always regarding electrical gremlins. Added 2 Quarts of Mobil 1 05W-40 Turbo Truck Formula Synthetic oil and 8oz of Blue Devil Rear Main Sealer, at 96,669 miles. My 2004 Cayenne S never had a huge problem changing gear: it was much more a clutch control issue, where the car would drop out of gear while waiting to pull out of a T-junction or onto a roundabout and leave you stranded at first, but suddenly find second, tearing off with a highly undignified bang. Altogether in 8 weeks of having it, it has been back to Porsche for 17 days, and needs to go back again! Go to the vw dealer and order the upper hydrolic timing chain tensioner same as the touareg 3. I have just went over 100K and have not had a problem.
General Comments: Average handling, poor brakes and the worst build quality. The dealer was not consistent on how frequent oil changes are necessary. I bought a new valve body from Porsche Â£1000 and had tehe rest rebuilt at a place up near Coventry. Even Porsche dealer where not able to find the problem, thanks to Renntech. Just because a car has been recalled does not mean it is not a reliable car. And one Renntech member thanks him find the problem and it take about 5-10 mins to fix it. Easy to replace and took about an hour of my time.
I do the maintenance myself oil and tune-ups I have always used mobile 1 oil 9 Qts. It was very difficult to get the bastards out due to the narrow spaces in the dash. By the way, thanks for a great site, it has helped me to resolve a few problems on my car already hatch struts, air suspension warning, fault on hatch door lock etc Best regards Isakpede Norway Contributing member. I was reluctant in purchasing new due to being a diehard 911 enthusiast so I purchased it used with extremely low mileage. Very disappointing not to have the car outside the door, but we will sort it out eventually. We prefer that guests take part in our community and we offer a lot in return to those willing to join our corner of the Porsche world. My wife's Accord is 240K and going strong.
Not too crazy about the flat spot on the throttle though due to the drive by wire system. And it has a weird problem. Corrective action Porsche will notify owners, and dealers will replace the fuel filter flanges with new filter flanges that have a protective film, free of charge. Sorry but it is way to narrow to get a good picture of where the temp-mix servomotors is mounted. I have contacted the manufacturer and was told that I would need to have a authorized service dealership make the diagnosis I have already been told, but there is not a authorized dealership within 500 miles of my location.
Try to find a high end independent car mechanic and avoid the Porsche dealers like the plague as the parts and labor will kill you. I would take them out on an extensive test drive. No major problems or repairs so far and I have already driven over 80K miles on it. I spoke with many 2004 owners, and they had the work done around 90,000 kms. No Review Date: 27th September, 2004 I have purchased a Porsche Cayenne V6 3. Which to me seems unnecessary.
Just let me know if it works on your engine. Some controls are overly complicated.

Performance is very good, handling excellent considering this thing's size and weight, no rattles or squeeks, and because it is a wolf in sheep's clothing, fun factor is great. But, things are getting worse with time. Stopped added coolant, drove home parked in driveway. This six-speed transmission is generally reliable, but develops problems with the valve body: the hydraulic fluid control assembly that regulates gear and clutch engagements.
Overrated Porsche - never again. Heaps of power if you want it. Added one quart of Castol Edge Platinum 0W-40 Excessive oil consumption and warm-start smoking, possibly due to deteriorating oil fill. It will rev away doing nothing, then it throws a gearbox fault and limp mode follows. Faults: Non stop problems since owning the car, which has only been 2 months.

Porsche has reprogrammed the tiptronic control units and updated the software from 2286 to 2475 but the same issue happened 3 weeks later. Thanks so much, i will definitely try this out tomorrow! I have never squealed the tires and have rotated every 5000. If I consider selling it I would buy a new one and stay on the V6 engine. This would be from 1200 through 1600 rpms, which again the engine sounds fine and the vibration is gone. For those of you who think the money is all for the Porsche name, you could not be more wrong.
Even Porsche dealer where not able to find the problem, thanks to Renntech. Dealer checking with Porsche to find out if they will pay something or all of cost to replace engine. I am pleased with the handling verse the power output, space and comfort. Replaced the gas tank vent purge valve assembly on the front of the engine. We stripped the valve body out of the car and sent it away.
