There are 2 owner-reported visibility & wipers complaints for the 2021 Porsche Taycanin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The heating unit and defrosting unit fail on the Porsche Taycans. I have seen this in other Porsche Taycans and it is nearly impossible to see through the windshield when it fails. I had to cautiously limp it to a Porsche dealership due to not being able to see out of the front windshield. There were no warning lamps or messages displayed simply zero heat and the driver side and passenger side windshield areas immediately fog up and it is impossible for it to be reduced.
Cabin heater in the car failed during very cold temperatures. Making the windows fog up considerably. Limiting my trips to short distances until this problem can be fixed due the safety concern of the windows fogging during longer trips. No warnings to the failure, dealer is aware of this being a common issue on the Taycan.
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.
