I replaced the battery knowing the original one was older and was weak. I installed a Costco AGM battery.

Also in the past month I have done the following:

Replaced engine air filter

Replaced differential fluid through Acura

Replaced tranny fluid at Acura

Acura have it a clean bill of health with all recalls completed. Need new rear tires but does that cause such poor mileage?

I am also noticing the car doesn’t do idle stop mostly. I get a message saying idle stop not available, although it does work after longer drives. From what I remember it use to work on shorter drives as well.

Looking for advice on how to troubleshoot since the car is running smooth and no other issues have been identified.

Thanks in advance!
