No, timing chain problems are common on these with half the mileage.
And those are still from lack of upkeep. The issue is the oil gets low and the timing chain starves without the low oil light coming on. GMs fix was to change the oil life monitor and make people change sooner since the owners could not be bothered to check the oil.
I have had 2 Cadillacs with the 3.6, 2 BiLs with that motor in their Cadillacs, and several customers with the 3.6. Never had to do a single timing chain in any. They all kept their oil level up.
Went in for a recall once. A CTS was behind mine came in for a timing chain and the tech pulled the dipstick out and nothing was on it.
