In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
Engine coolant pipes that are epoxied in by the manufacture work themselves loose over time and cause a catastrophic coolant loss that sprays coolant all over the rear tires causing a very dangerous situation. I had to have the engine pulled and the coolant pipes replaced and wielded in.
-
Major coolant leak on top of engine ..engine must come out $6000 est at porsche dealer. Common problem i told..porsche should recall this issue!!
-
Catastrophic loss of coolant due to coolant fittings popping out. Low speed, straight line driving at the time so there was no excursion, however rear tires were seriously wetted and if i had been in different circumstances it could have caused vehicle/property damage and/or personal injury.
How to read this page
Every figure comes from the National Highway Traffic Safety Administration's public complaint database, which holds every safety-related defect complaint filed by owners since 1995. We refresh it monthly and count each complaint once per component it names. Data through September 6, 2026.
NHTSA only accepts safety-related complaints. Rattles, paint, infotainment bugs and other annoyances are under-reported here, so this page is a map of what fails in ways owners consider dangerous, not a full reliability score.
Counts are raw. Use the year-over-year shape and the component mix, not the absolute numbers. Where a component maps to parts we stock, the row links to that category filtered to the year you are viewing. Air bag and seat belt complaints link to the recall checker instead, because those repairs are almost always covered.
