Example complaints

Electrical system: “1. Door panel Issue. I have a 2012 911, and have noticed last year that the door panels have popped up on both sides, it looks like the glue has given way. It seems that this is a common issue for Porsche 911. 2. Keyless Entry Issue. I was not able to lock my car by pressing by the door handle's button. I was able to unlock the car. I then tried on the passenger's side and was able to lock it. It's been going on for months, and every time it occurs I will have to spend minutes to get into the car.”

NHTSA complaint #11550582, filed 2023-10

Engine: “The automobile lost power on the new jersey turnpike. After gliding to a halt, fire was noted in the engine compartment which subsequently engulfed and destroyed the whole car.”

NHTSA complaint #10781046, filed 2015-10, 25,000 miles

Exterior lighting: “Tail light fall off the car while driving, catching it dangling from the car holding by only one wire. Upon inspection, they came off due to a broken plastic lug that was holding the taillights together. It appears that Porsche changed the taillight mounting design in the 991 after the 2013 model year, adding a metal piece to keep it together even after the plastic cracks, melts, or fails. Mine is 2012 so it will cost us a fortune for get it fixed, for something it was clearly a design failure from the beginning.”

NHTSA complaint #11621187, filed 2024-10

Fuel system: “Porsche 991 911 and 981 cayman/boxster models have an issue where the foam pads securing the fuel tank degrade or fall out. The initial manifestation is a squeaking sound where the plastic tank rubs against the metal body of the car. With prolonged movement the fuel tank can be damaged and a fire could result. Porsche is aware of the issue and has an internal service bulletin to fix it but only for customers under warranty. They claim the issue is only a squeaking sound but common sense would dictate plastic rubbing on metal several times per day will wear and start leaking. …”
