Thanks for the replies! Job is done. Sad that I had to replace the alternator on a '16 with 36,200 miles on it (yes, less than a tank of gas out of warranty). They sure did not skimp on the number of fasteners in that fender splash shield. 3 - 8mm bolts under the front, 7 - smaller hex headed screws, and a pile of screw headed expansion plugs. I did not have to remove the upper radiator hose, but the entire fan assembly did have to come out to make room to replace the alternator. It's held in with a 15mm bolt on the bottom, and a 15mm nut that threads on to the upper stud (8mm, if I recall correctly) to get the stud removed. It's a small consolation that the fan assembly is held in with only two bolts, it took quite a bit of time to get it all removed and replaced. That did appear to address the problem for me however. Before swapping it out, I was getting Check Charging System warnings and chimes, and the battery light would appear on the left side display. Measured voltage while running was only 11.8 volts max.
