The lane assist malfunction and periodically jerks. Very unsafe I no longer use this feature . To keep control of the vehicle. I never got it inspected. As the lane assist was in use and it would jerk it would alert me of a lane departure . I mention this to include every known problem I have experienced with the vehicle. The problem That brought me here. Is my engine light came on today. Leading up to this. I have had oil leaks since I've owned the car. Im adding oil in between oil changes due to it being low. In the beginning it was a hint of smell of gas in the oil. I was informed to do more frequent oil changes. Over time the smell of gas grew stronger . No Indication to a problem then. Now the smell of gas is prominent in the oil. When the dip stick is checked its always needing more oil and smells of gas and has blackness like burning in the oil. Now there's a check engine light on. And everything I looked up says to discontinue driving the car. I am having a mechanic look at it with a code reader.

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.

Car has a steering/pull issue. Car will pull to the right when driving on a flat straight road. Steering wheel will tighten up and then the pull starts to occur. Resistance must be applied in order to keep the car on the road. The lane keep safety feature has to be turned completely off or car will jerk back due to the pull issue. The pull issue becomes more noticeable after taking right turns. Car was taken to dealership with around 500miles on the car due to this issue. Dealership has attempted to fix this issue 5 times and each time said it was a alignment issue and was fixed. On the 6th time they said it’s normal and that’s how this car drives. Car was kept at the dealership for over 2 months straight with confirmation that it has a pull. Every time the car has been in the shop they have acknowledged the pull. During this time the emergency brake has activated twice while driving around 40mph for no reason.

I have noticed recently that the car keeps all of a sudden pulling to the right and I have not had the lane assistance on since a week after I bought the car. It is at 4000 miles right now and this problem began at approximately 3000 miles. Not sure if anyone else has noticed this but if it is just as if the lane assistance was turned on. I have also noticed that when I have my work bag which is approximately 40 pounds in my lunchbox in the front seat without the seatbelt connected the seatbelt warning does not come on like it did in my last car with the same items on the seat. Not sure if there is a different weight limit now but I figured I would add this in in case there isn’t.
