Example complaints

Electrical system: “The day we took our Porsche home, we noticed a lot of heat generation in the car- but we thought it will be fine going further, given the attention to detail of Porsche's Automobile Engineering. The following days were not any better for my daughter- she missed a major accident because of the unexpected burnt smell and loud warnings of an overheat of the engine by Porsche in the middle of a highway. Due to her excellent driving record for the past 5 years, she was able to manage and stop in the middle of the highway at the curb of the road. …”

NHTSA complaint #11429183, filed 2021-08

Engine: “Intermittent lack of acceleration when taking left turns from a dead stop. Car was a dealer loaner with 9000 miles on speedometer. I purchased the car in august, 2018. Within the first 1000 miles and in less than four weeks I experienced a serious lack of acceleration on two occasions when making a left turn, I reported this to the dealer and was advised that it was probably driver error caused by operating the brake and accelerator using both feet. I do not drive an automatic car using two feet. …”

NHTSA complaint #11165699, filed 2019-01, 10,000 miles

Other or unknown: “The Porsche Cayenne that equipped with leather dashboard are peeling off over the time. If the vehicle in an accident, the airbag on the passenger side dashboard may not deploy correctly. I am finding many cayenne owners are having this issue. I really hope NTSB can issue a recall.”

NHTSA complaint #11610103, filed 2024-08

Air bags: “This is not accident related, but what appears to be a systemic issue related to Cayenne and Macan leather dashboards. The issue is related to delamination of the leather dash cover that can impede the safe deployment of the passenger airbag. Many cars are affected and the repair can be a significant expense to owners (~$10K) for vehicles less than 8 years old. There should be a recall to address a largely unaware owner base for a potential safety issue.”
