What to check before you buy a 2005 Porsche Cayenne

A useful visit to this page takes five minutes. YearTell does not score years and cannot see the vehicle in front of you.

  1. Look up the VIN for open recalls at nhtsa.gov. This year has 4 campaigns on file below.
  2. Fuel system. Check for fuel smell, leaks and whether it starts and idles cleanly.
  3. Engine. Have a shop check for oil consumption, coolant leaks, rough idle and unusual engine noise.
  4. Transmission / driveline. Have a shop drive it and check the transmission: hard or delayed shifts, burnt-smelling fluid, and 4WD engagement if equipped.
  5. Skim a few owner reports below for Fuel system. Look for the same symptom repeating.
  6. Take that list to a mechanic. Do not turn the complaint total into a score.

The transmission has quite a bit of slop or play when placing it in park. I do not believe it could be parked safely in a residential driveway. Tranny knocks a little in low gears.

We purchased the 2005 Porsche Cayenne from my brother-in-law in August of 2022. He had owned the vehicle for at least a year before I purchased it from him. Shortly after the purchase, I noticed the engine light came on. On 09/12/22 a strong smell of fuel was emitting from the vehicle in a Walmart parking lot in Denton, Texas at approximately 1030pm. I noticed a large puddle of gasoline on the ground under the vehicle and it was steady stream of fuel while the vehicle was running. The vehicle was completely unsafe to drive for fear of ignition and fire. Due to the time and location, I had the vehicle towed to my mechanic approximately 3 miles away for diagnosis and/or repair. The closest Porsche dealership was approximately 25 miles away and the tow bill would have been excessive. Mechanic identified the problem as a cracked fuel filter flange/housing that sat on top of the fuel pump. The cracked fuel housing was replaced and the total for parts and labor was $462.48. No leaking fuel since repair. A few weeks later my brother-in -law contacted me and advised he had just received a recall (OCTOBER 2022) in the mail from Porsche for the exact part I had repaired (17V-576 / AH10). He mailed me the recall and I contacted Porsche for a reimbursement. They stated they only refund for repairs done at a Porsche dealership. I believe Porsche should cover the repair cost for their faulty equipment even after the recall was received. A Porsche Service Center would charge Porsche Corporate much more for this repair than what I paid. Please assist me in getting a refund for my expense of ($462.48) for the repair of Porsche's recall.
