Number 6 coil pack went bad. Flashing check engine light. All 8 coil packs and spark plugs replaced |
| 106000 mi | 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 |
| 82000 mi US $195 |
Replaced worn out engine torque damper. Easy 10 minute job. |
| 100000 mi US $178 |
High pitch whistling noise due to a tear in AOS. Car had 100k miles on it and most likely original part. Easy to replace and took about an hour of my time. |
