Porsche built the Cayenne to be the ultimate SUV, combining luxury and dependability in one attractive package. The quality assistance system provides an above-class experience for the driver while delivering the utmost comfort for all passengers. There is no better vehicle on the market today. Unfortunately, consumers of older Porsche Cayenne vehicles are a bargain you might want to avoid. Some Porsche Cayenne problems can occur before even hitting 100,000 miles.

What is the most common Porsche Cayenne problem?

Coolant lines are one of the most common Porsche Cayenne problems, according to Car Complaints. This issue results in costly repairs, sometimes proving to be a safety hazard. These are a few of the worst, and most reported problems that Porsche Cayenne owners have encountered. Owners of the 2004 Cayenne Turbo 4.5L share a common complaint. The coolant lines used in this model are plastic and run down the center of the engine blocks. The plastic cannot withstand high temperatures when the engine heats up. The pipes tend to melt, leaking coolant and creating safety concerns. This also impacted the starter, located under the coolant pipes.

Customers claim Porsche is aware of the problem but has not yet issued a recall. Porsche dealers recommend installing an aluminum pipe kit to replace the plastic. Estimates for repairing this problem are $3,500 or more.

The 2004 Cayenne model is not the only vehicle affected by this problem with the coolant lines. In February 2020, a class-action lawsuit was filed against Porsche. Plaintiffs own all Porsche Cayenne V8 vehicles, model years 2011-2019.

The lawsuit addresses problems with the epoxy bonding plastic coolant pipes. Over time, the adhesive tends to degrade, even under regular driving conditions. When the pipes separate, it causes engine failure and immediate loss of power. The vehicle stops operating without warning. Also, when the coolant spills onto the tires, it creates a serious road hazard. The NHTSA is investigating these claims.

Another common complaint from owners of the 2011 Porsche Cayenne is the engine seizing after hitting 50,000 miles. Drivers are reporting a check engine light warning before hearing a loud noise that completely shuts down the engine.

Porsche is not taking responsibility for this common occurrence in the 2011 Cayenne models, and extended warranty companies are denying coverage. Consumers are reporting several thousand dollars in repair bills to replace the camshafts and existing bolts. In some cases, the engine must be replaced entirely. 

Don’t overlook the Porsche Cayenne transfer case issue

With a luxury vehicle comes exorbitantly high repair bills. The 2012 Porsche Cayenne owners are experiencing repeated problems with the transfer case. In most instances, the part must be replaced, costing the consumer approximately $5,000.

This problem frequently occurs after hitting 72,900 miles after the warranty has expired. Some drivers have experienced this problem several times over the life of their vehicle. Porsche does not cover this common problem.

The 2020 Porsche Cayenne

The 2020 Porsche Cayenne is a great family SUV. With an MSRP of $66,800 up to $164,400, this crossover SUV offers many customizable options and engine choices to fit every driver’s budget. Consumers agreed, however, that many of the optional features in this high-priced ride should be considered standard.

Several new coupe models are being offered that provide a unique roofline and superior handling capabilities. Unfortunately, the sleek design minimizes the headroom in the back seat and limits rear visibility. Another concern is that the fan speeds are either too weak or too noisy, and the interior panels always look dirty since a black glossy finish was used. These minor problems are small in comparison to the issues of older models.
