Just saw a notification to check charging system along with error code P0562. Battery is only a year old.

any idea what might cause this?

My guess is either the alternator or battery connections . If you have a simple multi meter , you can check the alternator’s output with engine running, you should have around 14 volts .
Or it’s a battery cable issue. How many miles on your RDX anyway ?

Battery connections look good at the terminals. I'm getting 12.4 volts to the battery with the engine off, and 13.3 when running. 174k miles.

If you still have meter ,I’d check voltage with engine running with lights, blower motor and other high demand items on next . The alternator/ regulator should spike higher than 13.3 volts in my opinion.

My wife’s 2010 CRV alternator ( same design) crapped out at 140k , battery light on and a definite electrical smell if you will was present. I bought my RDX 4 years ago at 115 K with a replaced alternator installed.

I went with new vs rebuilt for wife’s ride for many reasons too …. Good luck

Got it tested at auto zone. Confirmed it is the alternator. Are they're replacements any good. Or am I better off purchasing from the manufacturer?

It's OEM but half the price.

For what’s it’s worth, I went with a new Duralast alternator from Autozone in August 21 because my youngest was working there at the time for $219 .

Where ever you buy , they all want that core full of copper for some reason …
