Porsche PanameraA recent class action lawsuit alleges that the engine cooling systems in some Porsche vehicles are defective, leading to expensive repairs.

The Porsche engine cooling system class action lawsuit was filed by Michael Xu and Daniel Vaz-Pocas, who say they both purchased Porsche vehicles that possess the engine cooling system defect.

Allegedly, Porsche refused to remedy the problem, and they were both forced to pay out-of-pocket to repair the issue.

Xu and Vaz-Pocas say that Porsche knew or should have known about the engine defect, but sold the vehicles nonetheless.

According to the two customers, the company did not inform vehicle owners about the problem. Allegedly, Xu and Vas-Pocas, along with many other customers, were financial injured by Porsche, because they would not have purchased their vehicles if they had known they were defective, and because they had to pay out-of-pocket for repairs.

The Porsche class action claims that the plaintiffs each purchased a Porsche Cayenne S vehicle and made their decision in part because they believed the Porsche vehicle to be of high quality.

The two car owners say that they each experienced their engines overheating while driving, due to the coolant system defect. They claim that they were forced to pay out-of-pocket for repairs, only to have the coolant system replaced with equally defective parts. 

The Porsche engine cooling system defect class action lawsuit says the affected vehicles include model years 2010 through 2016 Porsche Panamera vehicles with V8 gasoline engines and model years 2011 through 2019 Porsche Cayenne vehicles also equipped with a V8 gasoline engine.

According to the customers, the engine cooling systems are defective because the epoxy used to connect the coolant pipes can fail under the high temperatures of the engine. This epoxy failure allegedly causes the cooling pipes to separate from the cooling systems which in turn, causes the vehicle to overheat.

This reportedly poses a safety problem because, if the cooling system fails, the engines fail and the vehicle loses power. According to Xu and Vaz-Pocas, this can occur without warning, including while the vehicle is traveling at highway speeds.

The Porsche epoxy defect class action lawsuit goes on to say that when the cooling pipe separates, coolant liquid is dumped into the engine, onto the vehicle’s tires, and onto the roadway. This can allegedly cause the defective vehicle and the vehicles behind it to slip on the roadway.

The engine cooling system problem class action lawsuit asserts that Porsche has known for more than a decade that using epoxy adhesive to affix coolant pipes to the body of the vehicle is a design defect, and knows that there are other solutions available. However, Porsche allegedly continues to produce and sell cars with the defect in the interest of its own profits.

    We recently bought a Porsche Cayenne for our daughter. It started stuttering until you get over 50MPS. We took it in and they said it was the transfer case. Porsche admitted they knew it was a problem, but they were not issuing a recall. It will cost us $5300 to fix. How can we be added to this lawsuit?

  2. Delores Robinson says:

    Squeaky brakes in my 2013 Panamera Turbo. Radio turns off and in by itself. Now the coolant system issue.

    My 2010 Panamera is overheating how do I get on this lawsuit

  4. derek says:

    2018 Cayman is having overheating issues as well. Has been towed in for repair 3 times in less than a month. Each time it has been “repaired” under warranty but then overheats right away when I drive.

    I was left in the middle of South Africa with 4 passengers and luggage days before CHRISTMAS.All expenses,including transport of car to dealer and repairs as well as substitute car rental due to poor workmanship ,was for MY POCKET..

  8. Mark Cruickshank says:

    I have the same long list of defect on my lemon 2010 Panamara turbo. Full Porsche warranty and they keep telling me this is normal… I disagree.

    1. Eric says:

      you still have warranty after 10 years? Whoa.

      Anyways, I recently had my ’13 Cayenne GTS (NA V8) in for brakes and they told me I had an issue w/ my cooling pipes and it was over $3k to fix. Funny as I bought it CPO from same dealer. Ugh.

  9. Jo says:

    My brand NEW 2018 Panamera has not worked properly or consistently from day 1.
    It is currently in service again for the exact same reasons which are all issues with all the electronics and basically most of the time I can’t even get in to my car.
    I have a paper trail and the amount of work done in a new car is absolutely shocking
    It is a Lemon but they refuse to acknowledge it.

    Wipers malfunction error messages constantly for coolant -oil and check engine and key not found.
    Brakes squeal and it’s so embarrassing and I could go on forever!
    Porsche believes these things are all normal they give you a patronizing pat on the head-
    They are the WORST company to deal with because they actually don’t care about the performance of their products once they have your money.

  10. BYRON C BOGGESS says:
