ABS module is faulty. Confirmed by professional auto shops and it-??s a safety risk. Without this working properly, my car refuses to brake sometimes. Will not automatically stop when it needs to due to the spongy, unresponsive brake pedal. Kia / Hyundai have known about this for years and continues to sell these vehicles that WILL kill myself or someone else on the road.

The Kia optima 2020 2.4 every 3000 to 4000 miles oil change is metal shavings in the old oil. The clicking noise stared it around the 10000 miles mark and now is getting worse with 60000 miles, everytime I hit the gas and goes over 30 miles loose a lot of power and a clicking noise come out, now is getting worse. Is a new car. Already change a ABS pump and I keep my oil change to the date. I m afraid the car is breaking. Help.

It is impossible to use the brake pedal if the shoe size is US10+. the distance between the floor and the knee airbag mechanism does not allow the use of the brake pedal.

For the past few days I have been feeling a left to right movement at times when I press the brake pedal so after further checking I noticed it moves left to right when moved by hand my car only has 36128 miles so why is this coming loose already?

I own a 2020 Kia Optima (my second one in less than a year). Three weeks ago, I applied my brakes before entering a curve. In the process, I hit a bump (not a pot hole) in the road's and my brakes disengaged and I thought I would lose control of the vehicle because I was not sure the brake were going to engage in time for me miss a hit on collusion. The same thing happen again, yesterday. This is not the first time I have experienced brake problems with a Kia Optima. In my 2016, the same thing was occurring. The service shop replace a rod or something the braking system. I had a loaner Kia Optima (2019). I could feel vibrations in brake paddle when I drove over a bump in the road while applying the brakes. The same occurred in the first 2020 Kia Optima that I purchased last October. Kia country savannah try everything to solve the problem. Luckily, the dealership traded me I out of that vehicle before my first payment and was given a loaner vehicle until my current vehicle was located and delivered from another dealership. Now, I experiencing this issue with your company's vehicle. I was forced to trade-out of 2016 car due to known engine problems.

The fcw forward collision warning system seems to not get activated under any circusnstances. I have changed the sensitivity of the system to all levels and it never seems to detect the car in front of it. It never warns you of an collision.
