Experienced a sudden unintended acceleration while parking the vehicle. Right front tire climbed up on a parking barrier (shortened telephone pole) and damaged the right front bumper. No warning or trouble lights were on at that time, however, after restarting vehicle and heading home approximately half a mile down the road, all the warning and trouble lights came on, the steering wheel started shaking and the car wasnât drivable. We have no idea if there is concealed damage underneath the vehicle. We called Honda roadside assistance and they came and took the vehicle to the closest Honda dealership. At this time, weâre waiting to hear from them.
