Front windshield camera, controls adaptive cruise control, lane keep assist, lane departure mitigation, front collision mitigation, auto high beam, all the lights came on and all the features stopped working. We were 1500 miles from home when this happened had it repaired at a dealership $1300. I called Honda corporate and after 2 days a customer service representative called me back. He told me the vehicle was 2500 miles out of warranty and it's a car and cars are going to break down. That I should drive it back home and have the dealership repair it and they might be able to help with some kind of reimbursement. I did not want to drive it that far without all the systems functioning so he said well that's on me.
When the automatic start/stop feature turns the car off when the brake is fully depressed the car will sometimes not restart as designed. Further, it is sometimes accompanied by the forward collision warning light coming on and shutting the car off.
