Porsche Panamera and Cayenne Vehicles Cooling System Defect Class Action

Porsche Panamera

A defect in the cooling system in certain Porsche vehicles can lead to sudden failure and complete loss of vehicle power, according to the complaint for this class action. This can be extremely dangerous, particularly if the car is traveling at high speeds on highways at the time. What makes it worse, the complaint claims, is that Porsche has known of this defect for more than ten years. 

The class for this action is all current and former owners, purchasers, or lessees of the vehicles in question distributed for sale or lease in the US, including in Puerto Rico and other US territories and possessions.

Auto engines run at high temperatures and require cooling systems to ensure that they don’t overheat. At issue in this case are the cooling systems in model year 2010 to 2016 Porsche Panamera vehicles with V8 gasoline engines and in model year 2011 to 2019 Porsche Cayenne vehicles with V8 gasoline engines. 

The pipes in the cooling systems heat and cool, expanding and contracting with heat cycles. The systems also experience vibration from the engine and road conditions. In the vehicles at issue, the coolant pipes are attached to the thermostat housing with epoxy adhesive. Over time, the complaint alleges, the epoxy adhesive degrades, loosens, and fails, causing a sudden separation of the coolant pipes from the thermostat housing. 

When this happens, it poses two hazards, the complaint claims: First, it can cause a complete loss of vehicle power. Second, when a pipe separates, it dumps coolant into the engine compartment, on the vehicle tires, and into the road, creating slippery conditions for the vehicle and those behind it.

Repairs of these failures are expensive, the complaint says, because mechanics must remove other components to reach the failed ones. Also, the spraying of coolant around the engine compartment can cause damage to other parts. Worst of all, the replacement parts have the same defects as the original ones, so that the problem can occur multiple times during the life of the vehicle. 

The complaint claims that Porsche has known since at least 2007 that the use of epoxy adhesive in this system is a problem. According to the complaint, Porsche has known through its own records of customer complaints, its dealership records, information from the National Highway Traffic Safety Administration (NHTSA), warranty and post-warranty claims, and claims related to a similar problem in certain earlier-model Porsche vehicles. Still, the complaint claims, Porsche has never informed vehicle owners, accepted responsibility for the defect, or found a fix for it. 

The complaint lists its causes of action as the Florida Deceptive and Unfair Trade Practices Act, breach of implied warranty of merchantability, and a request for declaratory relief.
