2012 Porsche Cayenne — Should You Buy One?

Typical asking price: $15,000–$24,000. There are 2 high-severity known issues you need to know before handing over a check.

Kestrel Take

A Porsche SUV for Camry money, which the market has priced correctly. The V6 model is the sane choice and shares a great deal with the VW Touareg. The Turbo and GTS are magnificent and will cost more to maintain in a year than the purchase price suggests.

Known Issues for the 2012 Porsche Cayenne

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

Coolant pipe and thermostat housing failuresHigh — wallet impact

On V8 models the coolant pipes in the valley were originally plastic and failed catastrophically. Aluminum replacements exist. On a V8 Cayenne this is the first thing to verify.

Repair cost range: $2,500-$5,000

Air suspension failure (equipped models)High — wallet impact

Struts leak and the compressor fails. Coil conversion is possible but changes the character.

Repair cost range: $2,000-$5,000

Driveshaft support bearing and transfer case wearMedium

The transfer case chain stretches and the driveshaft center bearing fails, causing vibration and warnings.

Repair cost range: $1,500-$4,000

Carbon buildup and water pump failuresMedium

Direct injection carbon and plastic-impeller water pumps on the V6.

Repair cost range: $700-$2,000

Walk-Away Red Flags

  • V8 with no documentation of the coolant pipe update
  • Vehicle sitting low
  • Driveline vibration at speed
  • A Porsche independent shop absent from the history

Good Signs

  • Aluminum coolant pipes installed on a V8
  • Steel spring suspension
  • V6 model with complete Porsche or specialist service records
