Vehicle’s front collision sensor popped up on dash, vehicle lost all power. Almost was hit by a group a semi trucks hauling a wide load that wouldn’t have been able to stop in time. This is the 3rd time it has happened in a week and a half.
On a highway cruising at 70mph with the acc (adaptive cruise control ) on and following distance set at max a car from another lane turned into my lane and then continued to an off ramp. My car initially braked and then downshifted from 8th to maybe 4th and accelerated hard - scaring me and my passengers. I did add to the actions of the car by pressing the following distance button on the steering wheel a few times. I had owned a 2016 Sonata with acc and drove over 100k miles with acc operating. That is why I pressed the following distance button - to lessen the actions of the car when the car entered my lane. The 2016 also had a acc setting of fast, normal, & slow (I used normal). The 2023 has no acc setting. I did complain to my dealer and he said this was normal and nothing happened. I feel this is dangerous so reported it to Hyundai customer service. They told me to go to my dealer.
