Reliability & safety Rating

4.0 out of 5

Porsche wholeheartedly deserves its reputation as a premium carmaker – its cars are built to exacting standards and use top-class materials inside and out. A real reputation for quality has helped residual values to remain high and owners tend to be confident in their cars.

Porsche Cayenne reliability

Porsche cars have a reputation for very thorough engineering and their reliability isn't really in question – although it's unfair to expect any new car to be entirely immune to niggles.

Porsche hadn't appeared in recent Driver Power results but sprang all the way to the top in 2021 thanks to strong performances in every category, including top finishes in six of 10 categories. While it aced the handling categories, decent fuel economy may come as more of a surprise but it was considered relatively reasonable given the performance on offer. Just 14% of owners reported a fault within the first year.

There is a caveat, though, which is that any Cayenne is a highly complex vehicle that should be looked after correctly to remain at its best. If maintained according to Porsche schedules, a Cayenne should be a generally trouble-free proposition. 

Safety

Sharing its mechanical basis with the Audi Q8 and third-generation Volkswagen Touareg means the latest Cayenne can offer the same excellent crash-avoidance technology as its stablemates. As a result, autonomous emergency braking, active cruise control and lane-keeping assistance systems are all available.

The previous generations of the Cayenne SUV were never crash tested by Euro NCAP due to the model’s relative exclusivity, but the latest version has undergone rigorous crash testing earning a full five star rating in 2017. The standout scores being the impressive 95% score for adult occupant crash protection, and 90% for child occupant protection.
