There are 1 owner-reported driver assist & adas complaints for the 2020 Porsche Panamerain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The Adaptive Cruise Control keeps faulting randomly and triggering the seatbelt warning ️. Also when the adaptive cruise control fails the cruise control disengaes altogether. This is very dangerous when driving. I have taken this car to the dealership 4 times within 2 months for this problem and no one can fix it.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
