Adaptive Cruise Control Problems of Kia Motor Telluride

While driving on the highway under normal conditions (clear weather, no nearby vehicles within approximately 1,000 feet), I heard a sudden loud “bang,” immediately followed by a large crack forming across the windshield. There was no visible debris impact, and no external cause could be identified at the time. Based on similar reports involving this issue in other vehicles, this appears to be a potential structural or manufacturing defect rather than road damage. While using adaptive cruise control in clear weather and with no traffic present, the vehicle will randomly decelerate as if detecting a vehicle ahead when none exists. This results in sudden, unnecessary braking without warning or indication. The issue has occurred multiple times and creates a significant safety risk, particularly at highway speeds where unexpected deceleration could lead to a rear-end collision.

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.

While driving at highway speed and the adaptive cruise control engaged, the vehicle applied the brakes without driver input. The vehicle slowed gradually over several seconds even though there was no vehicle, pedestrian, or obstacle present in front of the vehicle. Road and environmental conditions were clear and normal, including clear weather, dry roadway, and unobstructed lane of travel. Traffic was flowing normally, and there was no lead vehicle. The driver was attentive and did not press the brake pedal. The braking occurred without any warning, alert, or collision indication and resulted in an unexpected reduction in speed, creating a risk of a rear-end collision from following traffic and on one occasion road rage (which has occurred due to this condition) as the driver thought I "brake checked" him. The vehicle has been inspected by the local kia dealership (spitzer kia of mansfield) and they could not replicate the condition. Kia has also been notified and a case number assigned (25773402) but with no resolution. This issue has occurred multiple times under similar highway driving conditions, indicating repeatable uncommanded braking behavior. Additionally, kia issued a “voluntary service campaign” for 2024 kia Telluride’s on July 31, 2025 for the same vehicle behavior. Unexpected braking at highway speeds creates sudden speed differentials and increases the risk of rear-end collisions, even when deceleration is gradual. The driver has limited ability to anticipate or prevent the event. No warning lights, audible alerts, or collision warnings were displayed. Conclusion the vehicle exhibits repeatable false or uncommanded activation of the automatic braking system during highway driving, consistent with a potential defect in the aeb/fca system. This condition poses a safety risk to vehicle occupants and surrounding traffic and should be reviewed by NHTSA.

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.

Vehicle has warnings for epb and lane assist along with active recall for roll away. Cruise control does not work as well. Wheel jerks out of your hand while driving has been to appointment 7/1 in which vehicle was not repaired. Dealer claiming they had no record of a “diagnosis appointment” new appointment set 60 days out.

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.

The lcd screen in the instrument cluster/combimeter went blank. The lcd display contains information such as digital speedometer, gear selection, odometer, distance-to-empty, and all adas information. Problem cannot be reproduced. The phenomena has only presented itseld twice (11/2023 and 3/2024). Certified kia dealer stated there weren't any signs of failure. Service proceeded to perform a hard restart on the system. There is a similar recall for this phenomena (21v577000).

While driving , the power steering went out making steering very difficult and unsafe. A multitude of warning lights flashed on and off. Several warning icons were subsequently sent to our hone app for a period of 10 days while the car was parked and we were in hawaii. There is an obvious issue with the computers electrical systems that effect safe driving and continue to send false warnings to the app. This steering electrical issue will hurt someone if not fixed.

The gauge center behind the steering wheel will freeze every couple of weeks and will stay frozen until the car is shut off. After a few hours I can turn the car back on and it will work correctly. The speedometer analogue gauge will work but the digital screen will freeze. For instance, yesterday it was frozen on 23 mph and I was in park! the issue this causes is that I cannot use the cruise control, change the display to view other info, the blind spot cameras don't work, or any other info displayed there. I have video and pics.

The contact owns a 2020 kia Telluride. The contact stated while her grand-daughter was driving with adaptive cruise control (acc) mode set at 40 mph, the vehicle accelerated unintendedly and the steering wheel seized, causing the grand-daughter to lose control of the vehicle. The vehicle crashed into a road sign. The air bags did not deploy. The contact stated that the grand-daughter was able to veer to the side of the road as the steering wheel became operable. The vehicle was towed to an autobody repair shop, who informed the contact that the edr failed to display crash data. The grand-daughter went to the hospital later, and was informed that she had sustained a minor concussion, a disc in the back and the neck. A police report was filed. The dealer and the manufacturer were not notified of the failure, the vehicle was not diagnosed nor repaired. The failure mileage was unknown.

I’ve had numerous incidents where we were driving with adaptive cruise on and the vehicle will inexplicably engage the fca system and slam on the brakes. This has occurred with no vehicles in front of me in clear conditions and had nearly caused a rear end collision.

The instrument cluster periodically stops working. The speedometer and tachometer stop working, and all warning lights flash on and off randomly. It shows the doors and hoods opening and closing on the display as well along with other warning lights. The cruse control fails to operate as does the front/side crash warning systems. . . . These warning lights also come on. This is an intermittent problem, it will persist for days and then will stop for part of a day, or multiple days and then return again.

2022 Telluride is undriveable due to safety alarms/warnings. The vehicle was towed to the dealership where it was purchased (findlay kia). It's been 19 days and they have not been unable to find the cause and correct the safety alarms/warnings. Alarms/warnings: master warning electric power steering awd system warning forward collision avoidance assist high beam assist blind spot collision avoidance assist Smart cruise system warning lane keep assist.

Dash gage cluster (tach, speedometer, fuel, and engine temp) all go to zero while driving. The digital speedometer readout is also zero. Basically the entire dash is dead minus the entertainment system which functions perfectly. This also shuts down all adaptive cruise and collision avoidance systems. Restarting the vehical will not bring dash instruments back. Ocassionally cycling to door locks and or disconnecting negative battery lead will bring dash instruments or they will begin randomly begin functioning again on their own. They always malfunction and come back as an entire cluster. I also have video of the vehical in motion with the instruments dead.

After driving about 10 or 15 minutes both the adaptive cruise control and the forward collision warning system stop operating. Even after you clean off the sensor it does not help. It randomly clears itself, but will also stop again after some time. This happens both on local roads and the highway.

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.
