2023 Kia Sportage: false forward collision warnings

Filed May 29, 2026 · Brakes, Driver assistance · KY · crash

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.

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.

At startup or during driving, all safety features will go into warning mode and disable, including lane following assist, forward collision avoidance, electrical parking brake malfunction, electronic stability control malfunction, automatic braking, and downhill brake indicator. All warning lights illuminate on dash until car is stopped and turned off. And even then they may come on again upon restart. This has happened intermittently since I purchased the vehicle and Kia says they don't know the source nor can fix it. Most recently, the car engine stopped while stopped at a traffic light when the warning lights started to cycle on.

I was driving a highway distance of 374 Miles mostly two lanes hwy. While driving I had my collision warning, distance between car indicator and adaptive cruise control in use. It did not happen all the time however when it did it was a violent stop. While driving 75 mph. The car recognized there was another vehicle in the other lane. It would give the warning sign and even if I tap the break it would slam on brake so hard that my passenger burn herself with coffee and the rest of us went towards the wind shield. Thank goodness for seat belts. There were 3 people in the car including myself.This happen 1 with AdA cruise control. I disengaged that feature but left the other features on. It happen two more times while returning home with just collision warning and . I am driving about 75 mph. Car doesn't recognized all the cars passing, then all of a sudden the collision warning comes is activated with a fast beep. As if it just saw the car and before I am able to tap the break it slams on break. I have taken it to the dealership and they could not duplicate it. Instead they turn off the feature. I told them it was on the highway , over 75mph, with other traffic. They indicated it was me and not the machine. If it was someone following me while this happened. At the rate of speed I was going and abruptly stopping. I would have died. Or been seriously injured. My car is not fixed. I DO NOT feel safe.
