I’d clean the front emblem in the grill and the windshield where the sensors are hoping it was just an obstruction...

Hello I just noticed a technical service bulletin.
TSB 23-008 - LKAS, ACC, or CMBS Indicators On with DTC U3000-49Applies To: 2017-18 MDX - ALL2017-18 MDX Sport Hybrid - ALL

Do you think this is causing my issues?
I don't have any check engine light codes when I connect my obd scanner.

Also does anybody know how much it would cost for Acura to apply this?
