On XXX, less than 24 hours after an authorized Porsche dealer released this 2024 911 as a successfully completed repair with the diagnostic codes cleared and no root cause documented, the vehicle suddenly lost motive power while traveling at highway speed. It entered limp mode with severe deceleration and displayed a red engine control error, forcing an emergency lane change across traffic to reach a parking lot. After stopping, an active and significant fluid leak was observed trailing from the engine compartment, creating a fire risk. The 12-volt electrical system then died and the vehicle required a jump-start. After power was restored, the transmission would not engage Park and displayed "P not available. Park on level ground only," creating a rollaway risk. The vehicle was occupied by the driver, a passenger who was approximately [XXX] pregnant, and two small children. The three distinct safety failures were the sudden loss of motive power at highway speed, the active fluid leak with fire risk, and the loss of Park capability after the electrical failure. Warning messages appeared during the event as described. The vehicle remains at the authorized dealer and is undiagnosed as of this submission, and is available for inspection upon request.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list.
