Kia Sportage collision warning problems

Filed Aug 24, 2026 · Driver assistance · AZ

I am reporting a concern regarding the Forward Collision Warning and Automatic Emergency Braking systems on my 2024 Kia Sportage SX Prestige. I have been attempting to understand the operating behavior of the vehicle’s FCA system using cardboard boxes as targets. I conducted observations at very low speeds (approximately 5 mph) as well as at approximately 30 mph. During these observations, the vehicle did not provide a forward collision warning or automatic braking at distances at which I expected the system to recognize a potential collision. I have not intentionally caused a collision or placed a person or another vehicle in danger. I am uncertain whether this behavior represents normal FCA operating limitations, the use of an inappropriate target, or a malfunction or calibration issue. I am therefore reporting the concern rather than asserting that a defect has been established. I am also uncertain what diagnostic or functional validation procedure Kia provides for this system. I have been able to find information regarding radar alignment, camera calibration, and diagnostic fault checking, but I have not been able to determine whether Kia provides dealers with a standardized functional test that verifies that FCW/AEB actually recognizes an appropriate vehicle target and intervenes at the expected point. The concern has not yet been reproduced or confirmed by a dealer or independent service center. The vehicle has not yet been subjected to a standardized ADAS functional test using a recognized vehicle target. No warning lamps or diagnostic messages have appeared that I am aware of. The potentially affected components are Forward Collision Warning and Automatic Emergency Braking within the vehicle’s Advanced Driver Assistance System. The vehicle is available for inspection upon request.

This is a statement from my daughter: I was driving and noticed a vehicle stopped in front of me. When I attempted to brake, I could feel my brakes sink all the way to the floor. I also didn't receive an alert from the Front Collision Avoidance system or any assistance from the Automatic Emergency Braking system. The vehicle was a CPO that had always been serviced at the dealership. Because of various surgeries I have had, depending on the severity of the crash, I could have been paralyzed for life.

Comparing this 2026 KIA Sportage to what I have in the garage with 2019 Lexus RX 350, 2018 MB E300, and 2021 Honda CRV, the front collison of this KIA does not work as it should. If I keep moving the vehicles toward a car, the collision avoidance should give me a warning an brakes for me, however, this 2026 KIA Sportage does not respond at all. In addition, in order for the front sensors on the bumper to work, I need to press on the brake. The dealer said that there is nothing with this system and there is no way to prove it unless I ram into another car.

I was stopped in the left hand turn lane, then accelerated to cross 2 lanes of traffic. I then let off the accelerator, and applied the brakes to stop, and the brakes did not function. I then rear ended a vehicle in front of me due to the intermittent loss of brakes. It may have also been the propulsion system kept going. Either way the vehicle maintained the same speed of about 15mph until I collided with the vehicle in front of me which stopped me. The brakes worked fine again after the collision. There also was no Forward Collision Avoidance system that was triggered in any way. This vehicle is a Rental Car.

I was parked in a spot outside the Service Department of John Kennedy Ford, waiting for my son, who was getting his car serviced. I couldn't see the door of the Service Department, so I decided to move to a position in which I could see my son exit the Department. I put the car into Reverse to exit the spot and it accelerated at an uncontrollable rate of speed backwards, striking two cars parked outside the Service Department, pushing them into other vehicles in the parking area. I put the car into drive to pull away from the cars I impacted and the car accelerated at an uncontrollable rate of speed forwards, striking a curb in front of the showroom, causing my car to veer into two new cars on the lot, sideswiping the last car and veering my car into a lamppost along The Fairway. The collision caused my car to stop, causing the Driver airbag to deploy. At no time did the forward collision avoidance system cause the car to brake itself. When the car was moving, the engine was revving at maximum RPM. I wasn't able to control the vehicle. The policed officer who investigated the scene said he did not see any interference from the floor mat, which he said is a common cause. Upon reviewing the activities leading up to the crash, I recalled attempting to use the remote start feature of the vehicle, which had been operating flawlessly. However, on this day, it took 3-4 attempts to get the vehicle to start remotely, possibly indicating a computer flaw. I was injured; no one else was. The vehicle is in the State Farm lot awaiting interrogation by KIA.

Purchased the vehicle 2nd hand January 29th 2025. Since then she has been in and out of multiple shops including Kia. Check engine light, loss of power on fwy, shifting/brake changes from a stop. From jerking, lunging, studder, taking off fast, not wanting to go at all. I was on these dips that I encounter almost daily and the collision warning went off. There wasnt anything in front of me. 2 weeks later I was cut off and had to swerve to avoid. Collision warning DID NOT go off. Driving on the fwy and the gas pedal pulled away from my foot as if it was accelerating. Kia has done a hard carbon, changed all fuel injectors. Last time they stated there was a factory defect with the rotors, changed all 4 rotors. Still she drives like this. Carmax, Kia and Daniels Tires NO ONE can tell me what is wrong! I have driven a 2024 same make and model and the car drove beautifully. Something is wrong with my particular vehicle. This is becoming frustrating. Please help. I drive often, I hike a lot. We are always on winding roads. I can't afford to sell it as I still owe. I love the vehicle, aside from this, like I'm just waiting for disaster to occur. Miles started at 14.5k and it's now 33k. Speeds have been anywhere from a complete stop to go and fwy speeds of 55 to 80.

I have documented the following issues: -84 instances of "Keep Hands on the Wheel" when my hands were on the 10/2 or 9/3 position. This dates back to March 2025 and has continued into December. -12 instances of the ER braking engaging with "Collision Alert" when no other vehicles/object/danger were around. The ER braking is the sudden, full force stopping of the vehicle staring in April 2025 and as most recently as 12/06/2025. -3 instances of the vehicle being in "drive" but not moving forward; only the engine revving. This started in August and occurred again in October and on 12/06/2025. -1 instance of the vehicle randomly shutting off while driving very slow into the garage on 12/06/2025.

Description of Crash: On [XXX], I was involved in a front-end collision while driving my 2024 Kia Sportage. Despite the impact, the airbags did not deploy. Additionally, the Forward Collision Assistance system did not engage or warn me prior to the crash, even though conditions were normal and the system was active. Safety Concern: •The airbags and collision assistance are federally regulated safety systems. Their failure put me and any potential passengers at serious risk. •I am very concerned this indicates a defect in the airbag and/or collision avoidance system. Damage/Injuries: My front end of my vehicle is completely destroyed, and so is my engine. As for myself I am experiencing some soreness and discomfort Requested Action: •I request that Kia and the federal safety agency investigate this failure as a potential safety defect. •I want confirmation that my case has been documented and reviewed for possible recall or repair action. State Farm Claim #: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
