general problems of the 2004 Porsche Cayenne

The contact owns a 2022 winnebago voyage . The contact received notification of NHTSA campaign number: 22v-545 (equipment) however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

I returned after being away for a few weeks, in may 2021. The solar panel had been on the inner windshield of the car following installation a few months prior. I found the car's 12v battery was almost dead (about 4 volts), and the solar panel's plastic frame was severely melted, causing it to deform and lift away from the glass solar panel. Photos uploaded below. From reading reviews on this product on the harbor freight website, I now see that this is a common problem. I don't know what the cause is. Could be that the cheap plastic is just not made to withstand summer heat (although I have 2 more of these in my other cars, with no problems), and that the severe deformation of the frame somehow shorted something electical inside the panel that caused the car's 12v battery to discharge, heating the glass panel and melting all the surrounding plastic. Or it could be that an electrical problem was the trigger, causing the battery to discharge, etc. Harbor freight is so far making it extremely difficult to try to raise the problem with them. I think this could be a serious issue, perhaps leading to a car fire. And if it is indeed an electrical fault that triggers this, then it could happen when parked in a garage (no solar heating needed), possibly leading to worse.

Engine coolant hoses are leaking antifreeze. Everytime I pour antifreeze into the car it comes out, im afraid it might damage something else, like the engine etc. They have plastic hoses on them.

The Porsche Cayenne is notorious for drive / cardan shaft failures. Had bad drive shaft noises, and subsequent premature failure, it was a worn center support dampener and a faulty center support bearing. I experienced banging, bumping, grinding noises from my Porsche Cayenne and was unaware at the time it was the drive shaft. I have outlined the the noises and causes below: - a clanking or clunking noise while accelerating or from deceleration to acceleration around 35to 40mph and while Cayenne was shifting from 2nd to 3rd to 4th gear. Around 5th and 6th gear going around 50-60 mph it stopped. If I kept the rpm under 200 it seemed to run ok, no issue, but if I pressed the accelerator hard or gunned it, it went haywire. It was the result of a worn and damaged dampener or diaphragm located on the center support bearing. This condition will allow for the drive shaft to travel up and down with variations in drive line torque. This movement will produce a loud clanking or clunking sound and make for a very uncomfortable ride. I later found out that this condition is one of the most common failures on the Cayenne drive shaft, all models 2003 to 2006. This should be a recall and free fix by Porsche because it has happened to so many of the vehicles and model years stated above! but no, Porsche quoted me $2,500 to fix it. Not fix the problem area, the hard rubber dampener on the center support shaft of the power train, which by the way is possible. No, Porsche would only replace the entire power train for $2,500.

Coolant line/plastic coolant hose failure. I was driving in traffic and my low coolant light appeared. Within seconds, the car began smoking and the temp. Gage rapidly began to rise. I had to turn the car off immediately in the middle of traffic to avoid possible engine failure. I towed the car to my mechanic and he indicated its a design defect from Porsche and the plastic tubes are now replaced by orem aluminum tubes. Upon further investigation, I was able to determine that the design flaw by Porsche was concealed. The Cayenne s is in the shop and I'm hoping that only the hoses need replacement and nothing else was damaged due to this issue. A huge dent in the wallet as this is a costly fix.

Porsche lurches,jerks,thuds,intermittent power loss when accelerating to pass another car. Engine,transmission/turbo system faulty and hazardous as power loss occurs when quick speed-up when passing power is critically needed. This power failure problem has occurred since car was bought new ivy me in 2004.
