The car's power brake system stopped working. We did not incur an accident just because we found a side road before the upcoming traffic light; otherwise, it would have been a disaster. This car also had other software issues, but it was not as alarming. We believe driving is unsafe. The manufacturer is offering a payment to get back that car and drive it. Still, unless the competent authorities take responsibility for checking that the Porsche Macan EV is safe to drive, our family will not be Porsche's guinea pig. We did not get into an accident just for pure luck, but what will happen if the issue occurs again? The car is under warranty, but another power brake failure can be fatal. It is not an easy position to be in.

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 2024 Porsche Macan S Diesel verdict →
