Mileage when owners reported a problem with the 2018 Cayenne
Too few complaints on the 2018 Cayenne list a mileage to say when owners reported problems: 5 of its 13 complaints list a mileage (5,000 to 22,000 miles), and a median is given here only with 10 or more.
These mileages say when owners reported a problem, not when a 2018 Cayenne wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.
Every model year together: Half of the 382 NHTSA owner complaints on the Porsche Cayenne that list mileage came after 59,000 miles (NHTSA complaints file of November 11, 2026). How many miles will a Porsche Cayenne last? →
Is the 2018 Cayenne a good year?
Complaint counts cannot say whether the 2018 is a good or a bad Cayenne: they rise with how many were sold and how long they have been on the road. They show how the 2018 compares with the other model years in NHTSA's file.
With 13 complaints, the 2018 drew the fewest of the 16 Porsche Cayenne model years from 2004 to 2021 with 10 or more complaints. The most: the 2014 (53).
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 2004 Cayenne | 38 | 25 | 91,000 |
| 2005 Cayenne | 32 | 21 | 66,000 |
| 2006 Cayenne | 41 | 24 | 77,000 |
| 2008 Cayenne | 27 | 24 | 72,340 |
| 2009 Cayenne | 15 | 12 | 67,500 |
| 2011 Cayenne | 30 | 18 | 64,017 |
| 2012 Cayenne | 27 | 20 | 49,900 |
| 2013 Cayenne | 40 | 24 | 65,190 |
| 2014 Cayenne | 53 | 33 | 41,000 |
| 2015 Cayenne | 14 | 5 | Under 10 mileages |
| 2016 Cayenne | 40 | 17 | 16,000 |
| 2017 Cayenne | 19 | 6 | Under 10 mileages |
| 2018 (this page) | 13 | 5 | Under 10 mileages |
| 2019 Cayenne | 48 | 8 | Under 10 mileages |
| 2020 Cayenne | 24 | 5 | Under 10 mileages |
| 2021 Cayenne | 21 | 4 | Under 10 mileages |
The linked 2015–2022 pages show NHTSA's September 15, 2026 collection, so their counts can differ from this table's.

What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2018 Cayenne lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2018 Cayenne.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 8 of the 13 complaints on the 2018 Porsche Cayenne give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA name counted: CAYENNE. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
- Recall-file names matched: CAYENNE and CAYENNE DIESEL.
