I guess my question is, does $844 sound reasonable to you? Considering I can purchase the sigma 100-400 new with 7 year warranty for a little more, it doesn't make sense to fix it in my mind.
I find it hard to believe that Canon needs to replace all those parts when the lens still works intermittently, it focuses, the IS works, I can take still take clear, sharp photos, but it's just not reliable, as it will work for a couple of shots, then will give the error. Turning it off and on sometimes clears the error, and a gentle shake of the lens seems to get it working again.
Sounds like a steep bill, but not unreasonable given the repairs needed. Not sure if Canon CA uses a prix fixe system like Canon USA (where it doesn't matter if they have to rebuild the lens or replace a switch, it's the same charge). For perspective, when my EOS M died for no apparent reason, Canon wanted $230 to fix it – that was based on the original (pre fire-sale) price of it, at the point I needed the repair (2 years post purchase) replacing the M was $230 and getting the slightly smaller and very moderately better M2 was only $10 more. So, I bought the M2.
In your case, have you considered a used 100-400 MkI, which you could possbly get for less than the cost of the repair?

Thanks for your feedback. My problem is why do they need to replace all those parts? Canon claims that it is so they can warranty the work. That's bull crap. just fix what NEEDS to be fixed and leave the rest alone! Scam artists.
You describe an 'intermittent' problem, where sometimes a power cycle fixes it and sometimes shaking the lens around fixes it. How do you know what NEEDS to be fixed? In fact, Canon may not know that either. Case in point, a couple of months ago, my Subaru started showing a traction control light and flashing brake indicator. You'd think the dealership would know the problem by reading the code from the engine, but they first replaced the O2 sensor, which didn't fix it, then replaced the steering angle sensor, which also didn't fix it. What did? Replacing the remote start controller. Go figure.
So I sort of believe Canon when they say they have to replace all those things to guarantee the work, not because they're trying to rip you off, but because the intermittent problem with semi-random ways to temporarily clear it could have many causes, and the alternative is to replace parts one by one until they find the right one. SO, easier to just replace them all and be sure the issue is fixed.

BIF's is what I mostly shoot. At this point, i'd rather take the repair money and add additional funds to purchase something other than a canon lens. (they aren't getting any more of my money) Any recommendations? any experience with the sigma 120-300 2.8?
3rd party lenses almost always have AF issues of one sort or another, because Canon doesn't share their AF protocols, Sigma/Tamron/Tokina/etc. must reverse-engineer them, and also spoof the camera by using a Canon LensID code (usually from a very old lens model, but sometimes not). For the price of a new Sigma 120-300/2.8, you could buy the excellent 100-400 II, and have enough left over to buy another one, just in case the first fails out of warranty. But if you want to sacrifice performance for pique, that's your decision.
