Failure 6 miles after service work...

Let me give you some idea just how far they were from having those bolts "torqued up and signed off by the mechanic."
Back when I was doing autocross or track every weekend I was also changing wheels and brake pads before and after every event. One time just before driving home from autocross I noticed the left rear felt loose pulling into the Texaco. Turns out I had completely forgotten to torque my wheels. I would always give each nut a good hard snap, probably about 40 lbs worth, then lower and torque. This time, no torque. Yet I was able to drive 90 miles to Bremerton, do 4 autocross runs, and go for gas before one wheel loosened enough to notice.
Your car made it less than 4 miles.
Torqued, my @.

My recollection is that lug nuts are torqued at 96 lb/ft for a 991. It's not that easy to loosen a properly torqued lug nut with a wrench, sometimes a breaker bar is required, much less having the lug nuts just loosen by themselves. I always use a wrench to initially tighten the lug nuts, and then follow up with a torque wrench. I expect that in this incident the lug nuts were hand tightened, and then the tech got distracted and forgot to use a torque wrench.

Thanks. Good to know. My wife has an Audi S5, and a couple of weeks ago she ran over a deep pot hole which damaged one of her tires. Fortunately this happened about four miles from our home, so she was able to drive home. I initially tried to remove the lug nuts with the wrench provided by Audi, but they wouldn't budge. Fortunately I have a breaker bar which enabled me to remove the lug nuts. For properly torqued lug nuts to loosen by themselves is beyond ridiculous.

I now always carry a torque wrench when our cars go in the shop. 70 miles after leaving Discount Tire, my wife's wheel came loose (not off) at speed causing vibration which pulled her into the wall adjacent to the highway. She was fine. Car, not sustained $7k in damage. And it ain't driven the same since the repairs.

"Porsche said the wheel bolts had been torqued up and signed off by the mechanic."
That falls under the heading of "Total BS." What a surprise that the mechanic said he did nothing wrong. Who would have guessed he would deny it?
The least they could do is take responsibility for their negligence.

They have now swapped the GTS for a new C4s convertible which I can have until mine is fully repaired. They say it should be all done by next Wednesday....
I do hope this will work in my favour for a PTS GTS for September/October this year.

This is so disappointing! I have had frustrating experiences with motorcycle shops and assumed that car repair shops would be better, but to not be able to trust a Porsche repair shop means there is no hope.....

This reminds me of Seattle dealer incident about 18 months ago where the Porsche mechanic left an oily rag on the 991 engine after an oil change. Car caught fire shortly afterwards when owner drove it......I believe owner was ok but car a disaster! Not sure on all details but dealership tried to deny it initially I believe. Guy probably is a Ferrari owner now. Lucky it wasn't Russell Wilson's car (dealer ad spokesman).

I'm boycotting Discount Tire.

After they repair the car I would trade it back to the dealer for another new 991. Let the dealer cover the depreciation for their negligence. If they don't agree seek legal advice.

Sorry to hear about this but glad no one was hurt, I would hate to think what the outcome could have been at 70+ , may want to take the mechanic for the first test drive once it's back, as others have said, hope there is no other damage that was not discovered.
Good luck
Good luck
