I know this has been covered but I can’t find a fix. I have a 2018 Accord Sport 1.5 with 67,000 miles and have always dealt with ACC going out periodically. I’ve learned to pull over and turn car off and back on that fixes the problem. Well back in February I took my car to dealership I bought it from for regular maintenance and they told me there was a recall and needed to do the update/system reset for the recall. It took like 4 hours and the next day the ACC and braking mitigation lights came on and they have not gone off. I didn’t have time to go back to the dealer until today. So it’s been two months that it hasn’t been working. LKA still works and has worked the whole time. Today they told me that it has nothing to do the with the update they did and that they needed to charge me $135 to take the front bumper off and take a look. I declined. Told them that it’s BS. That it stopped working the day after I had it there for maintenance and it’s never stayed off. They saw all the lights and errors and did nothing for me. What can I do??
