The vehicle is new Porsche certified pre-owned 2025 Porsche Panamera turbo with Porsche active suspension management. Vehicle has 2000 miles on the odometer. The car was at the dealer for an issue related to its online connectivity. As this was worked upon, I was allowed to pick up the car. At that time, I noticed a chassis error(image attached). The car's suspension. Was inactive and the ride was extremely low and bumpy. A small bump on the road caused me to almost lose control of the car. Some of the safety features were also disabled as this error showed up. The car was not drivable, so I brought the car to the dealership and the service manager told me that this error was noted by them as they were working on the pcm and should be fixable. However, after about 50 days of the vehicle in the dealership( April 9 2026- now), they have been unable to find a resolution to clear this error and I have been without the vehicle. I am being told Porsche germany and Porsche north America engineering are unable to identify or unable to repair the chassis computer and there are more vehicles in a similar situation around the country. I have called Porsche north America for support or help with explaining the reason why this brand new vehicle has this defect. I have made close to 20 phone calls after countless hours of being on hold and waiting, with 0 calls returned. I got one email back after 40 days saying the local dealership will handle my case and Porsche north America will close my case even though my car was still being repaired. I believe this may be a manufacturing/ design error and may involve several other cars. This needs to be investigated and Porsche needs to issue a recall to address this concern in other similar cars in the country.
The ride height sensor on the right front suspension is mounted to the upper control arm via a plastic bolt and bracket. This plastic mounting component failed under normal driving conditions. The failure caused the ride height sensor to malfunction, which directly affects the vehicle's air suspension system and its ability to maintain proper ride height and handling characteristics. When driving, I received multiple chassis height warning messages stating that the chassis was too high or too low or malfunctioning. The ride height sensor is a critical component of the Porsche active suspension management (pasm) system. Its failure can result - incorrect suspension height, affecting vehicle stability and handling - suspension system faults that may trigger unexpected warning conditions while driving - potential loss of driver control in the event of sudden sensor failure at highway speeds this failure is not isolated to my vehicle. A review of Porsche owner forums including rennlist and 6speedonline reveals similar plastic mount failures on the ride height sensor across multiple Porsche platforms, including the cayenne, macan, and Panamera. The fact that Porsche has since revised the replacement hardware from plastic to metal strongly implies the manufacturer is aware the original design was inadequate. However, no recall or technical service bulletin has been issued to proactively notify owners or provide a remedy at no cost. When the plastic bolt and bracket failed on my vehicle, my dealership replaced it with the current Porsche-supplied metal replacement hardware because the plastic parts have been discontinued. However, the updated metal bolt and bracket are physically incompatible with the existing control arm, requiring the control arm to also be replaced. Owners who are unaware of this incompatibility may drive vehicles with an improperly secured or non-functional ride height sensor, increasing safety risk.
Coolant warning light on - seeing leak coolant warning light for coolant level comes on. Seeing a leak at a hose. Leaking at coolant bypass hose under intake. Coolant pipes in thermostat housing are coming loose at the epoxy joint. Chassis system failure, the car will stop abruptly on roads. And if here's that these problems that are reoccurring have been recalls before, that have not been addressed.
I purchased the above-referenced car in July 2020 almost immediately after purchase the indicator light came on with chasis failure and the car lowered to a safe distance to the ground. Unbeknownst to me the car had been declared unsafe to drive previously. The airbags had been deployed and placed backward the front sensors were painted over and not operable. I had to take legal action against four years later the dealer who ended up reselling the car in 2021 for more money. No reporting of these documented problems.
