Is a Porsche Cayenne turbo a reliable car?
Does it have maintenance problems? Can you put a good exhaust system on it to make it
sound like a gts?
This will make it sound better than a GTS and look better. Heres a link to their webpage: http://www.fabspeed.com/958-turbo-turbo-s-2011/
Preventative maintence is key with the Cayenne.
There are a number of common issues on the Cayenne Turbo, just like every car (eg kardan shafts, coil packs and coolant tubes) but other than that, my car reached 130,000 miles without major issues when I sold it.
Camshaft Adjuster Bolt Shearing Problem, which can lead up to total destruction of the engine, affecting 2011-2012 Cayenne turbos: The camshaft bolt shearing problem affects 2010-2012 Cayenne V8 models (S & turbo). The bolt in question is an aluminum/steel core version, and Porsche's recommended update is all steel. Bolt shearing happens in different places, especially the head, and the affected engine will have varying degrees of damage, up to full replacement, which according to various Cayenne forums, happens frequently. Panamera V8 engines from the same & earlier time periods are also affected. Porsche issued a Workshop Campaign (WC-22 issued March 2013) to address a subset of affected vehicles. Some failures have occurred on vehicles outside the campaign. A Porsche dealer can run your VIN thru the WC system to see if your Cayenne is covered. For failures not covered by WC- 22, you can ask your Service Advisor to contact PCNA to authorize a repair or engine replacement under the Emissions Warranty which is 7yrs/70K or 8yrs/80K depending on multiple factors including the state the car was purchased in, because the failing part, the Camshaft controls emissions output and timing. The Federal Emissions Warranty is 8yrs/80K.
There is a good overall review of the Camshaft Adjuster Bolt Sheering problem by a set of attorneys in California. They describe: "The problem lies in the aluminum camshaft adjuster bolts which have a tendency to sheer off, which prevent the camshafts from running. If this occurs in the camshaft that operates the vacuum pump, the power braking will also fail, which will result in an extremely dangerous situation especially if the driver does not have the strength to brake the car without the vacuum powdered brakes. The bolts themselves may also drop into the engine and cause the engine to fail."
