2009 5.0 S/C. Anyone else had problems with...

...head studs pulling out of the block, causing head leak (coolant).
First sign I had was "coolant low" message.
Car never overheated.
When garage took it apart, initially thought head studs had worked loose over time.
However, when reassembling, it became apparent that the two loose studs had actually stripped their threads.
My engine is actually in 2009 L322 Range Rover.
Anyone else had similar? Have googled it and found no other mentions.
Have repeated this post in Land Rover.

I saw one reply in the LR section, and I have to agree too that threads don't just "strip themselves" for no good reason.
Once installed correctly, any bolt will stand up to the job it's been designed to do, until the time comes for its removal. Thereafter, of course, anything is possible.
You'd need to know the history of the engine and its maintenance, to be absolutely sure.
Have you owned the car since new?
Has it been subjected to any cylinder head work in the past?
Has the vehicle been involved in any accident damage?
