How often did you change the oil, what weight? Did it ever overheat to cause it to stretch? I am in the market to get an 11-13 QX56, but I have heard the timing change issues can be a nightmare of problems.biggie wrote: ↑Mon Jun 27, 2022 8:48 am'12 with 134k miles, timing chain stretch (replaced under the recall in '16) and lifter bucket missing metal.

Getting $5k from a junk yard for it. That hurts the wallet.
We picked up a '19 Armada Platinum Reserve with 19k miles 3 days ago.

Ouch, perfect change-outs, were you the original owner from when it was new? Just trying to think of why it would still happen when you are still following through with recommendations and everything and still kick you down.
We bought it in ‘16 with 44k miles.
