10: Porsche Cayenne
The Cayenne has been on the market for a long time, and with every year, the SUV gets a little better. But that doesn’t mean there have been hiccups along the way, as the SUV has had its faults (via Motor 1).
The Cayenne has had issues with the turbocharger leaking oil as well as the transmission solenoid going out. These are costly repairs on any car, but especially on a Porsche SUV.
