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.

What 2012 Porsche 911 owners say
Most recent owner complaints, unedited.
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.
Cruising on the highway and a transmission error comes up saying that there's no reverse gear. Got off the highway and even gears aren't engaring, no 2,4,6 gears. 1,3,5,7 gears are engaging. Turned off and parked the car for about an hour. Turned it on car drove fine but start/stop wasn't available and sport modes are not available. Had the car diagnosed at the dealer and the same symptoms and codes are exactly as SB-10054511-7606. The 2012 model year needs to be included.
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. Fuel tanks should be secure and not bouncing around. Please investigate the matter further - hundreds of owners have had the issue of an improperly secured gas tank.
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.
