Complaints filed for the 2018 Porsche Cayenne are spread thin across a small number of reports, making it hard to point to a dominant pattern. The most notable recurring theme involves dashboard leather delamination, multiple owners describe the leather covering on the dash separating or peeling over time, and several express concern that the material could interfere with passenger airbag deployment in a crash. A single report from a hybrid variant describes gradual reduction in battery range and electric performance at higher mileage. One isolated report describes a front driveshaft collapsing at low speed, and another describes a tire deflating while driving with an accompanying noise from the front passenger side. The dashboard delamination concern, specifically how the peeling material sits in relation to the airbag deployment path, is the most consistently raised issue across this complaint set.
