My car wasn’t starting at first when I push button then starred, however, it was acting same way each time I start since two days. I thought it may be a battery issue. This morning it didn’t start and now I see this Check 4-Wheel AHC system on dashboard. Any easy fix or shall I call dealership

I'd start by checking AHC fluid level. Fluid needs changing at 60K...and I know Toyota recommends it every 120K.

seems like your ACH level/fluid issue. Found this thread on the LC forums

Did you get to check your battery? If not I'd start there.

If you battery voltage is low it maybe flaking out the AHC computer causing the message.
