This is the first case of a stretched timing chain that has come across this forum in the last 4 years that I have been reading it. And 107k miles seems kind of low too. I question this diagnosis and recommend that you get a second opinion. How reputable is the shop that made the claim?
I just had my timing chain changed at 92,000 miles. I had it changed just as a precaution. I had to have my balance shaft replaced so the cost to do the timing chain was minimal. I think I paid around $300 for parts. Mechanic said the chain was in good condition when it came out though. 2010 food for thought, GL

You raise a good point when you mention the balance shaft issue. Perhaps the original poster is also experiencing the balance shaft issue that was common in this generation of engines and it is being misdiagnosed as a timing chain issue. How much are they soaking you for the balance shaft? $4-5k?

I paid $3700 for the balance shaft, timing chain, rear main seal and I think he said some timing chain cover, can’t recall. This is parts and labor. ( dealer tech side job) Only thing I would have wished was done at the same time is the motor mounts.
Edit: All parts replaced were as follows: Crankshaft Sprocket, valves for camshaft adjusters, camshaft expansion plugs, centrifuge housing cover, oil cooler seal, thermostat and gasket, timing chain, pulse wheels, timing chain tensioner, oil filter housing gasket, resealed upper and lower oil pans and replaced rear main seal, new exhaust clamps. Fluid on bill was 16 quarts oil, 2 gallons of coolant, 1 quart of power steering fluid, 1 quart of differential fluid. total for parts was $1750

Reason: added info for future reference
I would think a stretched chain means Timing can not be achieved, only leading to loss of power. As timing would be Retarded. So it’s doubtfull this happened before 150,000 miles .
I'm not an engine guy, but I would assume that there would be certain codes pointing to timing issues. And timing issues themselves can be for a variety of reasons. Hence my question to OP what were the symptoms (loss of power, misfires, poor milegae...etc) and how was diagnosis done pointing exactly to stretched chain. It would be helpful to know for the future.
BillyBenz,
What were the symptoms for balance shaft replacement? I thought those issues were related to earlier engines....
I was getting codes, P0016, 1208, 1200. I thought it was related to earlier engines as well. If OP does pull the engine or if any of you pull the engine, make sure to do engine mounts, I’m stuck doing them now not even 1k miles after doing the balance shaft and it would have been a lot cheaper and easier to do it while the engine was out. My timing chain was still in good condition when it was removed, I changed it as a precaution. The chain was only 300$ and my mechanic installed it for free because he had to take my old chain off to do the balance shaft anyway.
Timing chains last the life of a motor , so If it actually needed a chain your compression would be low and you would be burning oil and the motor would need a complete rebuild . Was compression tested? I bet not and that it’s ok. So you most likely didn’t need a chain.
