9Y0 common problems and failures
I bought a CPO 2019 Turbo about a year ago. Really love the car when it's working but have had a number of issues. Thankfully, all covered under warranty but it's getting annoying having to take the car into the dealer every 4-6 weeks. Here's what I've experienced on a car that was bought CPO with ~30K miles:
- Cruise control disabled, needed to be recalibrated (potentially not a manufacturing issue, likely the selling dealer forgot to recalibrate it after performing an alignment, but frustrating given I bought the car 1,000 miles from home and drove it back)
- Blown driver's side A-pillar speaker
- Excessive rattling coming from overhead Homelink/Sunroof console
- Malfunctioning coolant solenoid needed to be replaced (temperature was swinging +/- 100 degrees depending on if I was driving up or downhill)
- Rear view mirror heating element needed to be replaced (was causing all of my ADAS systems to be disabled randomly)
- Faulty oxygen sensor replaced last week
- Faulty low pressure fuel pump being replaced currently
I've also come out to a randomly dead battery once and have the exterior door handle cracking issue (I'm asking the dealer to see if they'll replace them).
When the car works, it's really lovely, and I had hoped to keep it for a long time, but at this rate I don't know if I'll buy another Cayenne and certainly don't plan on keeping this one past the expiration of the CPO warranty in 2 years.

Took car in for an oil change, they found wear on the upper control arm bushings, currently being replaced under CPO warranty.
While in for the bushings, they were also supposed to do a software update as part of a recall on all the driver assistance systems (I was excited about this as I had been dealing with a bug where every time I honked the horn I would get a brief ACC error). Apparently all went well with the update but when they went to wash my car, it threw a ton of new error codes and so now they are back to figure it out.
Going on two weeks without my car, which is pretty annoying. The good news is I haven’t paid for a car wash in months because my car is at the dealer so regularly.
