NHTSA complaint #11636331, filed 2025-01“Transmission fault causes car to be stuck in gear and will not shift. This issue appears to be happening quite frequently with these ecars, regardless of mileage. It's dangerous, especially if it occurs on the highway .”
NHTSA complaint #11603332, filed 2024-07“The main water pump on my 2018 Porsche Panamera 4S failed prematurely.

The major safety issue is that the car would not shift gears once this error message cam up. The error has occurred multiple times and, thankfully, did not happen at a critical time - i.e. merging onto a highway. The first time this happened was on August 6, 2020. …”
