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. …

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.
