2019 Porsche Cayenne owner complaints

The contact owns a 2019 Porsche Cayenne. The contact received notification of NHTSA Campaign Number: 25V896000 (Back Over Prevention). The contact stated that the cameras including the front and rear cameras were inoperable.

Porsche has released a recall campaign but after taking my vehicle to a Porsche dealership to fix the recall, they informed me that they have not been given a remedy to the recall.

The AC evaporator failed at only 50,000 miles which is a manufacturer defect, as this part is not designed to fail and should withstand the life of the vehicle. When I wrote to Porsche regarding the failure, they tried to indicate or even suggest that this is normal wear and tear and the price of vehicle ownership. That is not a valid statement! This failure is considered premature and there is considerable documented evidence and concern widespread throughout the internet to back up this claim. It cost us almost $9000 to repair and almost a month of being in the shop. This is a significant repair and we actually took considerable time to not only research the issue, but quote the repair with other shops since Porsche wanted almost $15000 to conduct the repair. We would like this investiga

Complaint regarding a battery-monitoring/sensor issue, 2019 Porsche Cayenne and Porsche’s subsequent handling of the related repair. On May 22, 2023, at approximately 27,625 miles, my 2019 Porsche Cayenne was serviced by Fox Valley Porsche under Repair Order 103905. While driving a “battery charging warning.” showed, I was very scared. Dealer diagnosed a battery sensor failure and replaced the 12-volt battery. The invoice shows a battery charge of 1,957.87, plus labor. Repair documentation states “WMJ9 — Campaign not required.” I am asking NHTSA to investigate, whether the battery-sensor condition that resulted in my battery being replaced was related to the condition addressed by Porsche campaign WMJ9 and whether this condition can cause premature or unnecessary 12-volt battery replacem

While driving my 2019 Porsche Cayenne S on the freeway, the check-engine light came on, followed by a message on the dashboard that read “Engine Control fault – Driving permitted – Visit workshop.” Moments later, the vehicle suddenly lost power and decelerated from about ~75 mph to around 55 mph, even though my foot was still on the accelerator. I am [XXX] pregnant and had our [XXX] child in the car at the time. The unexpected loss of speed in fast-moving traffic was frightening. I had to quickly change lanes to reach the slower lane and avoid being hit by other vehicles. After reaching safety, I drove the car to an authorized Porsche dealership, where technicians found an active water-pump leak with coolant entering the vacuum system, which may have caused turbocharger and engine-powe

When braking to a stop, the car lunges forward even when foot is on the brake. This occurs at slower speeds around 5mph right before a dead stop.

When car downshifts from 2nd gear to 1st gear, it lunges / jerks forward, even as brakes are applied. Porsche mechanic and Porsche Cars North America both indicate nothing is wrong with the transmission. THIS IS A CONSTANT ISSUE. EVERYDAY FOR THE LAST TWO WEEKS. EVERY STOP.

The vehicle lurches forward dangerously when coming to a complete stop. The brakes seem to release as the vehicle lurches forward.

2019 Porsche Cayennes (and other Porsche models) have LiFe P04 lithium batteries that have an internal Battery Control Module that causes a "Battery Low " indication. Porsche has been updating the software/ firmware for this module, only for it to fail again. Eventually, the battery will fail, lose charge, and become dead. There are no after market batteries available and if you are 1 mile out of the warranty period, Porsche forces you to buy a new replacement battery from them for over $2,000.00 USD plus labor. This battery failure condition for vehicles with this type of battery is well known by Porsche and they now use a completely different type of battery in their newer models. This failure should be considered a Safety issue and concern since the battery powers every safety feature t

Porsches with LiFePO4 Lithium batteries (like mine 2019 Cayenne S) have a software/hardware error that causes the battery to incorrectly send a code to the battery management system so that it will suddenly shutdown the battery permanently and will require a full battery replacement, which the dealers abuse its customers by charging $3,000 to $5,000 dollars and give a battery replacement date as almost one year later. Porsche has internal TSBs but it is not recalling all the customers to have the software update for the controller/sensor bug/defect so that the battery management system will not overcharge the Lithium battery and damage it or cause the battery to issue a software code that preventsbthe battery from waking up or be usable. Texas has temperatures of 110 F, and becoming str

Several times a month when my car comes to a stop the brakes malfunction and the brake pedal goes to the floor and the power steering stops working. It takes up to another car length to fully stop when this happens - sometimes just a few extra feet. It has caused me to damage the front end by driving into a bush. The dealer refuses to do anything because they can't replicate the brake problem and they state the steering problem is normal. I have been able to replicate the steering problems to them but because the brake issue happens only a few times a month I was not able to.

The adaptive cruise control has failed 4 times. As a significant driver in terms of miles driven, the lack of cruise control increases my fatigue and jeopardize the safety of all. Porsche dealer in St Louis explained there it’s not known fx

Perelli scorpion Verde tires started showing sidewall degradation and pitting in 2003 or earlier – the earliest photos we have are dated 2003. The tires had to be replaced due to the degradation and we requested the tire shop to look into a warranty claim. The tire shop changed hands and we went through four managers and weren’t able to get a clear answer, during that time the tires continued to get worse and pit. We found numerous reports on the Internet of the same tire having a identical issue and believe it is a material defect and safety issue of this tire.

The Waste Gate Arm has broken on my 2019 Cayenne. This is a widely known issue with Porsches. Feels like this needs a recall. It is absurd to me that the dealers want to replace the whole turbo unit at $7-9k when a simple weld can fix. I am 6 months out of the 7 year warranty but under the 70k mileage. I am pushing the dealer to work this out. But it is crazy that Porsche isn’t held accountable for a design flaw.
