My 2019 Cayenne (the supposed epitome of German engineering) suddenly flashed: battery broken. After just 4 years. I ignored it for more thana year as the sensor often report issues that do not exist (e.g. tire pressure etc). Then it turned red and asked for immediate attention. Dealer #1: “Replacement lithium battery, €2,800. Delivery in 2–3 months.” Dealer #2: Same answer. Here’s the kicker: This isn’t an isolated case. Hundreds of posts on Rennlist, Reddit, and Porsche forums describe the same failure — the infamous LG li-ion starter battery in Cayenne 9YA models. Porsche knows it. They quietly reverted later Cayennes back to AGM lead-acid batteries, and even shipped ~⅓ of early cars in the US with AGM because they ran out of li-ion battery supply from LG. Yet dealers today still push you to replace with the same fragile lithium pack — for nearly €3,000 — which will likely fail again. The real fix? A Chinese OBD recode dongle: €200 A Varta AGM 95Ah battery: €200 30 minutes of work. Total: €400. I did it myself. Works perfectly. And no “battery monitoring” errors. Thousands of Cayenne owners are left with a broken, overpriced solution while a robust, low-cost alternative exists. Meanwhile, Porsche shareholders wonder why the company just dropped out of the German DAX blue-chip index.

I ordered an item from the Porsche Online Store and received the wrong product. What followed was over a month of wasted time: I called customer care more than 10 times, received multiple incorrect return labels, and was asked to “wait again” every time without any real solution. I even had to go to DHL several times because of their repeated mistakes. Customer service was unhelpful, impossible to escalate to a supervisor, and in the end, Porsche didn't refund my money yet. For a brand of this level, the experience has been extremely disappointing and unprofessional.

Déçu par les concessions Toulouse et Montpellier. Amortisseur cassé à 30 000 kmssu Taycan!! J'attend toujours qu'ils me rappellent depuis 3 mois. Pas professionnels.

Ganz schlechter Service oder besser gesagt kein Service. Drei E-Mails an den Vorstand wurden einfach nicht beantwortet. Das Porsche Navigationssystem ist das schlechteste, was man auf dem Markt findet. Jedes kostenfreie System ist besser. Das Kartenmaterial ist total veraltet, obwohl ich jährliche Update-Kosten bezahle. Aber da wird nur die Karten des Wohn-Bundesland geupdatet. Bei Reisen absolut ungeeignet. Werde jetzt das jährliche Update kündigen. Porsche was ist nur aus Dir geworden???? Eine Schande nur.

I’ve been a loyal Porsche customer and long-time fan of the brand, but my recent experience with Porsche Cars North America has been deeply disappointing. My 2018 Porsche Cayenne developed a well-documented transfer case issue—a known defect Porsche itself admitted by offering an extended warranty for affected vehicles. In my case, the issue started before 50,000 miles, and symptoms were initially misdiagnosed as tire-related by third-party service shops. Based on that advice, I replaced all four tires unnecessarily. When I eventually took the car to Porsche of West Houston, they confirmed the actual cause: a failing transfer case—exactly the issue Porsche covered under its extended warranty program. Unfortunately, because I wasn’t aware the issue was covered under a time-limited extended warranty, I missed the October 2024 deadline by a few months. Despite this, my car’s low mileage, documented history, and diagnosis by an authorized Porsche dealer should have been more than enough for Porsche to offer goodwill coverage—especially for a known and admitted defect. Instead, Porsche customer support repeatedly denied assistance, refused to escalate the case to decision-makers, and provided templated responses that ignored the facts. They even contradicted their own dealer’s findings by claiming the failure wasn’t a manufacturing defect—despite having issued an extended warranty for this exact issue. This experience doesn’t reflect the quality, integrity, or customer service you expect from a premium brand like Porsche. I expected better—and others should know what to expect if they’re out of warranty by even a few months, even for known defects. I still love the car, but this experience has made me rethink the brand.

Porsche Preston Great experience from reception to collecting my car after software upgrade Darien was fantastic Thanks again Rob

Bought a car from Porsche Centre Exeter back in 2022. Was worried about repair costs, so bought an expensive follow on warranty from them. Never heard from them again. No follow up, and no courtesy call to ask how the car was. That’s poor, especially when the salesman said that is what he would do. 2025, the Porsche got traded in. Contacted Exeter to ask how I can comply with the Warranty refund process. I followed this to the letter, but was told it could take a month. Nearly six weeks later I am still waiting for the money (over £1,000). Worst thing is the lack of communication and lame excuses every time you ask about the refund. 9th July, still no refund Porsche. WHY? Lessons learned: don’t buy a Porsche, and definitely don’t buy a warranty from them. 15th July, no refund!!!! 16th July, refund. Like getting blood out of a stone. Shocking brand.
