Editor's note
Avoid the 2019 Cayenne, which has 67 owner complaints and a score of 40, and the 2020 car, with 69 complaints and a score of 42. Buy a 2012, 2014, 2015, 2017 or 2018 car, which score 92 to 95 on 28 complaints or fewer, or a 2022 to 2024 car. Read the full note on the model page. 2021 specifically: 45 complaints on record, score 55/100 — read the year table on the model page to see where it sits among its siblings.

I attempted to start the car about 30 minutes later and the car would not start and gave an error message that said "change driver" I tried both keys and neither would allow the car to be started.
