Dec 28, 2022Driver assistance

Twice in the past two months, I have been driving down the highway going 70 mph with no car in close proximity to the front of me and the automatic emergency braking has activated, suddenly braking for no reason. In the first instance, there was a car in the lane to the left of me, and the second time cars on both sides of me. But in neither instance was a vehicle close to them front of my vehicle. The second time the car felt like it was going into a skid when the braking activated. I took the car to the dealer (Irwin Hyundai) the first time and they told me the sensors on the car were not properly calibrated when the new car was delivered to me. When I called Irwin’s today after it happened a second time, I was told the car was “functioning as designed” but they would look at it. I am scared to drive the car at this point given that the brakes randomly were activated while at high speeds and without any basis for activation.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2023 Hyundai Tucson Fuel Cell verdict →
