While driving on the highway on an extended trip my cruise control dropped its speed from 71 to 65 without warning. On one occasion it happened while I was in the passing lane with a lot of traffic behind me. It created a very dangerous situation before I could get into the right lane. Another incident was when again I was driving along, no one in front of me, beside me or behind me and the speed dropped once again. Had I been in traffic who knows what would have happened. I have turned the automatic breaking system off because while on a trip I was in the right lane when a car cut me off. The breaks went on and the car went totally out of control! I have filed a complaint with Hyundai and after waiting 8 weeks for a call regarding my case number they refuse to acknowledge that it is a manufacturing issue. I have had the vehicle into the dealer 3 times and they have not been able to replicate it by driving around the area, but have not taken it out on the highway at a higher speed which is when it occurs and when one would use the cruise control. I have only 9,000 miles on the car at this point and no remedy in sight.

Car stopped accelerating on the highway and held me at 40mph. This happened twice. Then before being able to get it in for service while driving the car made a loud bang and came to a rolling stop again on the highway and the transmission control system alarm went off and the car would not move. Had to get towed off the highway and in a rental now. This was a brand new 2023 hyundai kona sel limited.

While traveling at 70 mph on the freeway my 2023 Kona with less than 2,000 miles dropped into neutral and lost speed, almost causing a crash. I-??m lucky the driver behind me braked in time. The dealer has informed me that the transmission needs to be replaced.

The cruise control on this 2023 Kona has not worked since the day I purchased it. When the cruise control is engaged it will suddenly decelerate, but the cruise still appears engaged. It sometimes then suddenly reaccelerates. This causes traffic to suddenly back up behind me, and also to be in danger in front of me when it reaccelerates rapidly. I informed the dealer immediately of the issue. They advised there was a 2022 in their shop for the exact same issue at 8,000 miles. They asked me to bring mine in, which I have done now three times. That shop now has 4 Konas with the exact same issue, yet they do not have a fix. The Hyundai forum boards are full of this same complaint. I have contacted Hyundai Corporate. They also don-??t have a solution, but won-??t take back my new vehicle. I have less than 1,000 miles on this Kona - most of that from driving one hour to/from the dealer 3 times. I have been understanding and professional in my dealings with them however, I have run out of patience. I did not get what I paid for and am being asked to put myself/my family in danger driving this vehicle back and forth to this dealer who doesn-??t even have a fix.

The car is set at a speed for cruise control. For no reason it loses power, after a while it returns speed as set. At the beginning the doors weren-??t working for locking and unlocking by the handle. Seems okay now but I made a video showing the rear camera staying on while driving. Also included, two pictures of maintenance reports with different results.
