The 991 TTS is the first Porsche that I've ever owned that hasn't had some kind of major issue that could cause an engine failure or other catastrophe. My 996 C4S had the potential of IMS bearing failure, which could suddenly destroy the engine. My Cayenne S had the coolant line issue that could lead to hydrolock and sudden engine failure. My 997 TT had the plastic coolant line issue that could cause all the coolant to spill out suddenly on the rear tires, causing loss of control. So far, the 991 TTS doesn't have an issue like that. It's also the only Porsche that I've owned that hasn't leaked something onto my garage floor. No yet anyway....

Heater valve on both my 14 and 15. Also had an actuator on my 14 go I think on the blow off valve or something? It wouldn’t make boost.

'15 turbo. So far, so good with around 21k miles. Oil and brake fluid changes. Into second set of tires on OEM five lug wheels, but recently swapped for a set of SC2s on F1-Rs for the summer/track.

2014 TTS with 20k on the odometer and a Stage 4 from Sam, no mayor issues so far. Car is a beast, and yes, I daily drive it!

33,000 miles on my 2015 Turbo S Cab.
Not a single issue, and it was tracked quite often in 2015 and 2016 before I got a 981S to dedicate to the track.
The 991 TTS Cab is the perfect car. Has been my DD for 3 years now, track time as well. No issues whatsoever and 33,000 perfectly enjoyable miles on the speedo.

Anyone up over 60,000 miles on theirs? There was a traded DD TTS cab at a P car dealer with 95,000 miles that had no issues. Theres a 70,000 mile 991 GT3 on the other forum that hasn't missed a beat.

I'm at 45k on a 2014 TTS with absolutely no problems. I've put ~11k on it myself in the past year.

15 TTS with 32k. Had a spoiler failure warning at speed on the freeway in the past month, didn't affect handling. Took it in to the dealer, told was necessary to replace the air supply module for the front spoiler. All done under warranty so not sure of the cost if the vehicle was out of coverage. Forum search will show that a few others have reported this issue as well.
