With my ever quest to replace my current Audi S4 Avant, the Cayenne is always at the top of the list. I struggle between getting a truck or a Cayenne. I am not thrilled about driving the truck but will take the Cayenne places I am not sure it should go. That is a different story. So my question is, have you guys noticed or thought that the GTS Cayenne might be less maintenance than the Turbo's? I dont hear about too many people having blown Turbo's on the Cayenne but thought it worth asking. Seems like the shaft issue is the most common.

Any thoughts?

Not really. They both have pretty much the same issues. The only thing you might see on the Turbo that a GTS wouldn't have is oil leaks from the turbo/intercooler piping.

Are the issues fairly isolated to the cardan shaft? I have of course found some higher mileage Cayenne's but am pretty wary of such an expensive vehicle out of warranty.

Nothing major that I can recall for the 957. Cardan shaft (center support bearing), and high-pressure fuel pump (should have been covered under recall/campaign). I would imagine water pumps will start being an issue in the near future, as I don't think they changed the design much over the 955.

Check out the December 2010 issue of Excellence magazine or the current issue of Excellence for potential issues [ or ones should have checked if you would consider buying used] of the Cayenne.

Summary, though is that Cayennes, including GTS have proven very
reliable. Much more so than Audi.

Hi XR4Tim,

Sorry I'm new to Porsche so may have some stupid questions. In regards to below:

- Nothing major that I can recall for the 957. - is the 957 the 09/10 cayenne GTS model?
- Cardan shaft (center support bearing) - how often do you see/hear that this breaks?
- high-pressure fuel pump (should have been covered under recall/campaign). - Do you know if this is for 09/10 GTS? Any issue brought up after recall done by Porsche?
- I would imagine water pumps will start being an issue in the near future, as I don't think they changed the design much over the 955.- how soon (mileage wise) do you think this will start to fail?

I am in the market for a used GTS so just preparing myself (hopefully not getting myself into a disaster)

-957 is the 2008-2010 generation of Cayenne, including the GTS.
-I have not seen a cardan shaft center support bearing break on a 957, but they use the exact same part as the 955 (2003-2006), so it stands to reason that they will fail as well. I think all of these center support bearings will fail at some point. The ones that I replaced were in the 60k-110k mile range, and were 5-7 years old at the time.
-High pressure fuel pumps were replaced under recall for most '08-'10 4.8 liter engines, it certainly did apply to GTS models. I have not heard of any issues after the recall, though I did have to replace one twice on a Panamera 4S because the new pump was faulty.
-Most failed 955 water pumps that I replaced were at 7-8 years of age with mileage as low as 40k miles. We'll probably start seeing failure on 957 water pumps in a couple of years.

I've only done one but the water pump replacement on a 955 is fairly simple, I wouldn't worry too much about that possibility.

ok thanks for above comments.
