RE: Coolant hose break
I had the coolant leak as well. This so called smart truck, which is supposed to alert you before a big problem happens, didn’t. I accelerated into traffic and lights went nuts on my dash flashing coolant check now. I pulled over and coolant was leaking like crazy.
At the mechanic shop (my 2003 is out of warranty), they replaced the plastic tubing for the aluminum. The 3 tube one is the one that cracked; the lower plastic one held but was replaced as a precaution. I called a Porsche dealer and they told me that changing out the pipes at the dealer would have cost me $2200.00 minimum. He also changed my thermostat as a precaution as well. $1200 plus later, I get the truck back and not more than 3 days and only about 100 miles and my truck now squeals as its starting and has a hesitation (when attempting to pass or merge). It feels like a chugging and happens only when slightly pressing on the accelerator (one footed driver here). I turned it back in and now I am told that I need a starter.
It was $500 in labor to get to the broken pipes that sit above the starter. Now it’s another $500 in labor to get the starter out. My mechanic told me this morning that a new starter from Porsche will be $800.00!
The hesitation (a different problem) he says is from bad spark plugs (at $9.00 each). Though after reading a few posts here, I am not to sure.
I have 76k miles on my truck, with minimal issues until now. I don’t count anything I went through under warranty… who does? (But I do have a large stack of receipts for warranty work that has been done)
As a few others posted, I too am left wondering of the reliability of my truck now. I see quite a few older Cayenne’s on the market with less mileage. I wonder if they know something I don’t. I was once told by a mechanic that I shouldn’t keep my 1999 Mercedes CLK 430 past 75k miles. That is when everything starts going bad on the car. I have 74k on it and I am crossing my fingers. But is that what is happening to the Cayenne (another German product)? A good friend (a Porsche mechanic at a Porsche dealership), told me that after 75k, it’s a likelihood that the ball joints will need replacing. Which is a BIG MONEY fix.
I am left with questions and worries. Any thoughts?
I was also told that the coolant pipes will not be on any recall. They are just changing them as they come in (but not for free). But, from 2005 and newer, the trucks are built with the aluminum pipes.
