On December 29, 2022, the heater unit in the car failed. This caused ice to form on the inside of the car, all windows. Winter in Chicago. Dealer said they are aware of other Tacans having this came issue but there are no parts available and could be 4 to 6 weeks for parts. it is now February 15th and still no parts and the car is unsafe to drive as you can not see out of the windows. If you look on the website in Europe there are reported over 800 of these cars with the same issue and now Audi is having the same issue. These cars are unsafer and should be removed from the roads.

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Porsche Taycan 4s With Performance Pack verdict →
