I suddenly received errors that my sensors weren’t working, and I can no longer use my cruise control. The car has less than 60,000 miles so it still has the full bumper to bumper warranty. I have never had a collision.

Condensation builds in front of the camera. The car starts jerking all over the road with no warning. There is no error other than noticing that the car cannot keep itself in the lane.

I was driving at night on a freeway marked as a 65mph speed limit. I had the adaptive cruise control turned on and set to automatically follow the road speed limit. There was intermittent rain at the time.

I'm surprised there are no safety recalls on this vehicle given how Cruise Control operates & how close to the Cruise Control toggle switch the steering wheel is indented for hand placement at 10 a.m./2 p.m.We purchased a 2023 IONIQ 5 on 02/25/2023.When the vehicle was delivered to us we were not told that the cruise control does not disengage when the brake pedal is applied.It merely pauses.There is nothing in the owner's manual that addresses cruise control operation.In any other vehicle we have owned, including other Hyundai vehicles, cruise control cancels when the brake pedal is depressed.Without proper training/information & without cruise control being addressed in the owner's manual we had no way of knowing this.2 months after purchasing the vehicle, while pulling into a parking space driving 3 MPH I stepped on the gas & the vehicle returned to the previously set cruise control of 45 MPH.Whereupon it went over a parking bumper, landscaping, curb, $ into a busy street, scraping the passenger rear portion of the vehicle & damaging the wheel.We took the vehicle to the dealership, Larry H.

I was traveling 70mph on Interstate 70 when I heard a loud “pop” sound and the car immediately slowed down to 20mph in heavy traffic. The care then would not go over 20mph.The car was charged at home the night prior. On the dash was the “stop vehicle and check power supply” warning.
