2014 GL450 needs possible engine replaced or timing chain

Hi all! I am a new MB owner. Just bought my GL450 in Nov. Last week it began making a ticking sound when I started it. Took it to my mechanic (not a MB specialist) and he thinks it needs a new engine. Quoted me upwards of 15k. He said even if it's timing chain, after labor I would be close to the cost of a new engine.

I knew these things were expensive to own, but never would have imagined this..especially after just purchasing. Bought it as is, so there's my first mistake.

Anyone delt with this issue? What was your cost?

Wouldn't cost 15 grand to change chain. Find other mechanic also check if you have check valve installed on chain tensioners.

Have the cylinders scoped for bore score. pretty common, there is a ton of info here on it. #5 seems to be the one to go badly first.
