It could be the "improper clearance between the starter gear and the gear on the torque converter causes the grinding and damage to the converter gear." I have a 2013 Crosstour with push start and started having the intermittent grinding noise issue instead of starting after about 45-50K miles. I'd ask about it when getting routine maintenance and there were no issues found. It kept happening more and more. I'm up to 168K miles now and finally found the advice online to 1. replace starter, 2. replace battery, or potentially replace with higher capacity battery, 3. rotate flywheel one bolt. My mechanic did 1 and 2 and it worked for a week. Then he did the third fix and it was wonderful, no issues... for 2 weeks. Just when I was starting to get over my PTSD when starting the car it wouldn't do anything except power all the bells and whistles, but no engaging the starter or engine. The odd thing is that it started when a friend jumped my battery. The next time it wouldn't start I had to call AAA and they put their jump box on it, and it wouldn't start. I had them try jumping with their truck and it started. My mechanic got it to start 20 times the next day with no issues, let it sit overnight in the cold, and the next day the key fob wouldn't even unlock the doors. He opened the door with the key from inside the fob, and couldn't start the car. I went there and used the key in the driver door and turned it left 3 times which makes the windows go up and down. This must have reset something and I was able to start it, only after he used jumper cables and another vehicle to jump it. I drove it to a Honda dealer where they were expecting me. They just called and said the after-market starter my mechanic used is bad, so they are replacing it with a Honda starter. That is supposed to fix the problems. My mechanic and I are skeptical. He thinks they will replace the starter because it makes them money, and then they will reprogram a module, which will actually fix the issue. I believe him because I've was burned before by another Honda dealer who said I had to have my timing belt replaced and started the work before calling to ask, then when I couldn't afford to do it, didn't put it back together properly, leaving 1 bolt loose and 2 other bolts off completely (or they were loose too and came off) so that it couldn't be driven after 20 miles. Turns out my Crosstour doesn't even have a timing belt.
