The collision alert system is out of wack. The system is at a glitch era where as no cause prompts the alert. I am now responsible to disable all systems prior to each drive to avoid unnecessary automatic braking. The following are of concern: Automatic Emergency Braking Blind Spot Warning Forward Collision Warning Lane Departure Warning Lane Keeping Assistance Parking Collision Warning Rear Cross Traffic Warning

My vehicle has been slow to start and I have had all other issues come on on my vehicle as far as lights as far as the forward collision warning light has came on and the check driver attention warning light has come on as well while I’m running my HVAC past the level 2. I have also had my battery tested and that has tested fine. I have had my alternator tested and the first time it came back good the second time it came back failed and the third time it came back good.

Power train incident - • transmission holding gears, jerking between shifts, gear shifted into S mode on its own and stuck there, unresponsive acceleration, locked up steering/inability to turn the steering wheel and total loss of drive power. • happened while merging onto a highway in one of two split lanes for highway access. A merging semi truck in the other merging lane almost ran into me because I could not give it gas. Me and a local police officer who saw me broke down and stopped to provide additional cover, were nearly hit several (6) times from other vehicles and semi trucks due to malfunctions happening. • diagnosed by Kia dealership and was told there was a major electrical failure which caused the electrical oil pump to fail and need a new transmission. Although my VIN doesn’t list recalls, similar issue to the recall on my same year/make/model under the federal safety agency Campaign Number 21V519. • Warning lamps/messages shown in photos attached. __________________________________ Forward Collision warning incident - • front forward safety system light appeared on dash, then moments later a warning appeared and the vehicle braked on its own detecting a vehicle in front of me when there was not another vehicle in front of me within vision!! • happened while driving in a 55mph zone, a vehicle was driving behind me when this occurred and that vehicle almost slammed into the back end of mine causing a crash. • problem not yet inspected on vehicle due to blown transmission from above incident and inability to start/move the vehicle.

My electrical system failed. While on park I was unable to shut of the vehicle using the engine start stop button. After waiting for the vehicle to automatically turn off. The vehicle started trying to restart itself. The negative battery post had to be removed for the vehicle to stop. The entire safety system failed and all warning lights are still displayed on the dash. The backup camera and radio display went completely blank and was unavailable.

My 2021 Kia Sorento X-Line Prestige comes with Driver Assist features. One is for steering. Without warning it will disengage, particularly on a 2-lane highway, or when entering a curve in the road. This is dangerous. It needs to come with a warning that Driver Assist can flake out on 2-lanes and on curves, and is fairly useless unless you are on a straightaway on an interstate. This has happened to me multiple times since I bought the car from the Heiser dealership in Wisconsin.

1) Automatic Braking: Twice, Car has auto braked in the middle of a 4-way intersection when a car was stopping at the light. Car has auto braked in the middle of the 3rd lane (fast lane) on the highway during rain. Car has auto braked multiple times when reversing out of a parking spot. In one of those incidents, I have to drive forward in order for the car to move; turning it off and on does not reset the vehicle. The auto-braking while driving especially on the highway causing rapid decceleration could result in another vehicle rear-ending me. 2) MANY transmission issues: jerky transmission, car moving backwards while in drive (usually uphill, doesn't have to be steep), car stalling in park or when going up steep hills, traction control kicking on and engine downshifting (even though the roads were dry).

I was on a straight road no cars around the collision sensor went off and slowed me down. Another time it kept slowing the passenger side wheel down as the traction control was going off it did this 2 separate times. Got down the road some and it did it 2 more times but with the driver side. Last week I pulled into my drive way and was in park when it started telling me traffic was coming from the left, like I was about to back into something, I can't remember if I had shut it off at this time due to someone had fell out of the 3rd row when her foot was caught in the seat belt trying to exit the car. I called my nearest kia dealer and was told they were so far behind and since I did not buy my vehicle from them it would be last. I asked if an accident was to happen who would be responsible and he couldn't answer me.

KIA's manual gives instructions on two different ways (having two is a bit odd) to disengage their adaptive cruise control (KIA's name for it is Smart Cruise Control). Neither works. It is not possible to disengage SCC and use regular cruise control. This has been brought to the attention of the dealer from where the car was purchased (who has been working with us non-stop) as well as by me to KIA via their website. The dealer's service department has inspected it and cannot find a way to disengage the SCC. (Other safety features built into the car can be turned off). KIA is balking at finding a fix. I cannot use cruise control in this car without also accepting the SCC feature. I find it dangerous unless it is what I want engaged. I prefer to be in control of my vehicle and do not want the car adjusting my speed for me. If I'm approaching a vehicle and signal to pass, but first get to close to the vehicle I wish to pass according to the vehicle's software, the car slows down as I move into a passing lane. Even if I have plenty of room for someone who may already be in that lane, my vehicle slowing down until the camera and software determine it's 'safe' again poses a problem. I can give other examples, but am sure you get the idea. Suffice to say, other brands of vehicles have a way to disengage adaptive cruise control features. KIA's manual states it can be disengaged, but as stated, those directions do not work. KIA needs to make this right. Since I need to give a date next, please realize this has been ongoing since our purchase on April 30, 2021.
