The front radar FCA/SCC is misdetecting vehicles in other lanes and often slams on the brakes for no reason. Other times it lights on the dash and says the system (radar detection) is off or is blocked, when it clearly is not. Kia had this same issue with the 2020, 2021, and 2022 Kia Telluride and issued TSB SC243 (with a software update). I have been to 2 different dealerships, and one had a bunch of excuses and the other dealership had no idea what i was talking about. The car was about 21 months old and millage 20,000 miles when the issue began.
My Lane keep assist in my 2023 Kia Forte GT Line does not function as intended. It frequently pulls me into the lane with oncoming traffic as well as the lanes next to me. I'm unable to pinpoint when, where or why but I do know it typically happen in one spot of my town but everywhere else seems random. It's incredibly dangerous.

I have been driving my car, utilizing the Adaptive Cruise Control, and on a few occasions, have received a 'Check Forward Safety System' error message. Additionally, when utilizing the Adaptive Cruise Control, my vehicle does not recognize the vehicle in the lane directly in front of me, but instead, will recognize the vehicle in the lane to the left of me, as though it is in front of me (i.e. - my car has slowed down and/or initiated emergency braking when unnecessary). I contacted the dealership today, July 14th, to schedule an appointment, and they said the soonest they could see me is July 24th. This is unsafe because when the vehicle has initiated emergency braking, if someone is close enough behind me, they WILL run into me. And it has happened when I have been on the interstate (75mph) as well as local streets (40mph). Prior to this beginning to happen within the last couple of weeks, there were not any signs, warning lamps, etc. to provide a warning.
The car is slamming on breaks at random no warning it is going to cause a reck a 18 wheeler almost killed us that was behind us. And I can be driving down the road and the wheel try to jerk me into another lane. This car is not safe. But is not having any warning lights going off that anything is wrong
The 2023 Kia Forte LXS model rear camera often fails to identify people, objects, or other vehicles presenting a hazard to vehicles that are backing up. It fails to identify people and vehicles in the blindspots and is quite unreliable leading to several serious close calls in the vehicle. Due to construction of the vehicle it is important to have these features working correctly but they do not work correctly in the rear camera. This is especially true if it is night, if it is sunny, cloudy, or if there is precipitation. It also happens under normal driving conditions as well. These failures render the safety feature hazardous as they mislead a driver into believing that they are safe when using the camera and warnings as a secondary feature to assist looking around the vehicle. Even when looking back physically due to certain blindspots and using the camera features to augment this activity it often fails again causing many close calls and creating potentially hazardous situations especially when backing up in parking lots or garages, in driveways, and on the street.
