We drove for sea level by the coast up to Sequoia National Park for a camping trip on a very hot day. Once we got above 7,000 the Cayenne started stumbling, had no power, and eventually would barely run. We pulled over to the side of the road, hitched a ride to our campsite, and drove it to our campsite after that. No further problems. I took it to the dealer, who could find no problems. From researching online forums, it appears this model is occasionally susceptible to vapor lock
