2014 mdx sh AWD says emissions system problem when starting, then it said all wheel drive system problem too a minute later. Shut car off and restart, the AWD error goes away. My scan tool gave P0175 in the past and I cleared it. That seems to have come back although I am on the road at the moment and need to scan again. I’d previously cleaned the MAF but did not replace it. At that time I cleared codes and I was ok for many months. So I’m thinking either the maf itself or O2 sensor(s) could be bad but I don’t want to throw parts at the problem unless I have more to go on. Suggestions?

 

Im thinking your experiencing a battery failure. Have the battery load tested

 

I am experiencing this with my 2019 MDX. It comes and goes. No issue with driving. Took it to the dealership a few months ago and they couldn't find anything wrong because the lights didn't come on. Have anyone solved this issue?
