NHTSA complaint: 2022 HYUNDAI TUCSON — SERVICE BRAKES
I was driving down the highway going about 60-65mph with cruise control and LKA on. I turned my blinker on to switch lanes, checked my blind spot, and moved over to the left. As I was doing so, a semi switched lanes from the left into the right (my new lane) right in front of me. The truck then slowed down a lot, and usually my Forward Collision Warning would say something if my Adaptive Cruise Control isnât on (or is and Iâm just going too fast to slow down) neither of those things happened. No warning. No automatic brakes. No slowing down. I tried to engage the brakes manually but nothing happened. I slammed into a semi at around 60mph because of 3 different system failures. Not only did I hit the semi at 60~mph, apparently my brakes didnât work at all and I spun out until I hit the concrete barrier on the highway. If my brakes had engaged automatically, I could have slowed down enough to avoid the collision altogether. And if they had engaged manually I could have at least minimized the damage to my vehicle (and myself) because I wouldnât have hit the concrete barrier as well.
