Running costs

As you’d expect, running any Cayenne is costly. Insurance ratings range from 44 to 50, while all are subject to the luxury road tax supplement until year six. Expect 35-40mpg from a PHEV, but more like 25-30mpg from V6 petrol cars; the V8s are more likely to average no more than 20mpg.

Services alternate between minor and major, which are priced at around £1,100 and £1,600 respectively, although exact costs vary depending on spec. Those prices might seem steep, but with a service interval of two years or 20,000 miles, they’re not as bad as you might think.

Recalls

Porsche has recalled the Cayenne Mk3 eight times. The first two were in March and November 2019, because faulty software meant the brake wear indicator didn’t work. Fuel leaks on some cars led to a recall in May 2020, while sub-standard lock nuts were fitted to the rear suspension of some cars; that recall came in May 2021.

Cracked engine blocks led to a recall in June 2021, then a month later another was issued because of insecure steering columns. The two most recent recalls came in February 2022 and August 2024, both related to suspension issues – the earlier one concerned the rear set-up and the later one was due to components in the front.

Driver Power owner satisfaction

There have been no appearances by Porsche in our new-car survey since the Cayenne Mk3 was launched. With the brand accounting for just one per cent of the UK market (with 20,000 sales), it’s a niche player. But in our 2024 Brands survey Porsche came fourth out of 32, with numerous category wins, including for interior and exterior quality, interior design, steering response and driving pleasure.
