What has been anyone’s experience with reliability and maintenance costs on a Cayenne?
People who buy Porsche products are not concerned about reliability or cost ( which is outrageous by the way ).
Frankly you need to look at a Porsche forum.
If you have to ask… You can’t afford one.
Porsches can be very reliable cars but they are expensive to maintain and repair.
Consumer Reports rates the 2016 much worse than average reliability, has too little data for the 2017, and predicts the 2018 (a redesign) will be much worse than average. Still, owner satisfaction is above average. They are expensive to maintain and repair - especially the Cayenne. All other Porsches have better reliability scores.
According to Edmunds True Cost to Own, expect to pay a little less than $2000 per year for maintenance and a little more than $2000 per year for repairs once the warranty runs out. This assumes you use the dealer for maintenance and repairs and drive 15,000 miles each year.
