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.
