Adaptive Cruise Control problems of the 2024 Kia Motor Telluride

This car has a feature that will automatically detect the speed limit and sets the cruise control to an amount relative to it. If speed limit detected is 45, for example, it can automatically set the cruise setting to a configurable amount, say +5mph, and when detected, sets the limit to 50mph. Generally that works fine. However, near us is hwy 190 and is marked with road signs as a junction. Often times when we approach that junction the car "thinks" the speed limit has changed to 90mph and causes the cruise control setting to say, 95mph, causing immediate unexpected acceleration! this has now happened many times for me, at various intersections approaching hwy 190, in various directions.

On several occasions in city traffic the vehicle notified the drive to "check surround area for safety. " this warning is normally associated with a potential for impending collision. In at least one case, the vehicle was stationary at stoplight. In one case, the vehicle was moving slowly (< 10 mph) and was either starting or stopping at a stoplight. The vehicle automatically braked with the same warning as above for no apparent danger visible to the driver. Additionally, while driving at highway speed, the vehicle's adaptive cruise control (acc) was unable to identify that it was approaching vehicle until it was < 2 car lengths from that vehicle. The automated systems had no trouble identifying vehicles in adjacent lanes (as evidenced by the electronic display). The acc appeared better able to identify cars in front if they changed into the vehicle's lane from an adjacent lane. In other words, the acc could more easily track an identified vehicle changing lanes into this vehicle's lane from an adjacent lane rather than identifying a vehicle in the same lane that this vehicle was approaching.

When active cruise control is active the forward collection activates when their are shades and sun breaks in the road. Also when cruise control is activated, the forward colition should slow down and or stop the vehicle whne it approuches a vehicle in front of it. Often when approuching a stoped car etc infront or foward of the Telluride it does not break or slow down, it acts as if their are no obsticials in front of it. I have brought the vehicle to dealer when it had less than 3000 miles for this issue and will be bringing it back again on 1/28/2025 for this reacuring issue. Just today 1/17/25 it happened 7 times within a 5 mile travel.

The dashboard will turn black while driving. It will reset after disconnecting the battery, but it will do the same thing a few days later. Also, with cruise control, the car will suddenly slow down on the highway when no vehicles are in front of the car.

Upon starting car, display control cluster was black. No visibility of speedometer, turn signals, or any other vehicle control are visible. Restarting vehicle did not correct issue.

The vehicle will randomly hit the brakes hard and the collision warning system goes off. This happens when there is no obstacle or vehicle near the vehicle. It happens on 6 lane highways and the interstate. It almost caused numerous accidents before paramount kia's solution was to disable the navigation assisted automatic braking system.

The drivers screen has gone black and the odometer, speedometer, gas guage won't work. The odometer has been stuck at 5570 according to the app since the event even though I was able to drive to and from work that same day. The blind spot warnings are not working and either is the navigation. The light for the shift is also not working. The car is only 5 months old.

I leased this vehicle brand new in 2023 within a month my screen with my speedometer went black and I had called the dealership and they told me to unhook the neutral on my battery to reset the computer, it did work. And then anytime it rained got cold snowed or the roads were wet all my accident on avoided systems would say there's a problem and they would be disabled. I text the sales manager several times so between that and me having to unhook the neutral in the battery to reset my speedometer I was getting a little upset I took it to the dealership and they said there's no trouble codes and I said exactly because I unhooked the neutral which clears the trouble codes they had it for over a week and put 300 mi on it and told me they couldn't find anything wrong and because there was no trouble codes kia would not do anything about it. I had it down there again for a recall told the service manager and he said just think of it this way it's like having your truck back where you didn't have all those when it goes out and laughed. I had emailed kia corporate several times and they said I needed to take it to the dealer and the dealer said there's nothing they could do because there's no error codes but even this morning January 20th 2026 on my way to work no snow rain or anything and everything shut down again. The dealer sells manager has many text messages with the images of my dashboard and the warning lights. It just amazes me how the dealer in state college blames kia and kia tells me to have the dealer look at it because I've only had it there once which is absolutely not true I had it there a few times discussing it but because one was a recall and the other was an oil change they're not counting that.
