Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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

“While the vehicle was charging, the protective sheath near the power outlet of the charging cable had possible electrical or fire damage. No warning lights were illuminated. Upon turning off the power and unplugging the outlet, it was determined that the plastic near the plug melted and caused the power to short. I have been unsuccessful getting the manufacturer to resolve the issue. A recall under APB6 was issued but did not include model year 2018 which uses the same cable that is impacted with the recall.”
