Vehicle lost power steering completely. Has been inspected. Steering wheel sensor needs to be replaced. ABS light active as well as steering wheel light. No reason as to why this happen but it seems to be and ongoing issue for Kia Optima owners after reading other reports online.
Sticking Steering. Steering Wheel seems to 'stick' at a 12 o'clock position causing an 'over steering' problem. You drift from left to right as the Electronic Steering tries to correct the drivers reactions to the Sticking. This is an obvious 'DEFECTIVE' part and can cause a loss of steering. Kia Consumer Assistance Center does not recognize this as a serious problem, maybe you will. This will be my 3rd Steering Column replacement. (1) Original, (2) Replaced at 7,500 miles, (3) replacing at 99,600 miles. Please look into this. Kia needs to 'Recall' their cars before people get killed.
Driving on highway 54 all of a sudden vehicle seized up on me at 75 mph in the dead of night, steering was difficult to control and hit an object while trying to stop off the highway IN A BLIND CURVE! Was stranded for 6 hours until local shop towed vehicle and replaced condenser-radiator-fan ( object was debris on side of highway) could not get car going and a smell of electrical short coming from under hood. Have not been able to fix problem and have spent 11 days in Carrizozo NM trying with bewildered mechanics to get me back on the road. They replaced starter -fan-radiator-condenser-changed fluids (motor & transmission) to find out motor unable to reset. I’ve spent over 6,000.00 dollars in motel-tows-parts -labor -due to this vehicle. I found out of recall when I was told to buy an engine. This car almost took my life due to sudden engine failure on the highway in the AM hours.

About a month ago my traction control light came on and I would lose power steering. For a brief period of time maybe a day or two the light went out and I regained steering. Since then it has come back on again and I have had no power steering since this period I know there is an active recall on certain aspects of this and believe this is part of it, however I am told that my problem is not part of the recall and that I need to pay to have the safety issue fixed on my own.
About a month and a half ago my traction control light came on and I lost power steering. For a brief period of time that day the light went off and I regained power steering. Later that same day the traction control light reappeared and has been on since causing me to lose power steering. I have spoken with the manufacturer and they claim that this problem does not fall under any recall therefore they are not responsible for anything.
While driving the vehicle dash lights for the steering wheel and traction control come on and the steering gets hard as if no power steering. I pull over turn car off, check power steering fluid and belt, no issues. Turn car back on no aforementioned dash lights turned off and steering is fine. This has happened a few times within the last two months.
"half" of the engine was replaced in july 2019. Now burns oil like crazy. On october 29th 2019 while driving at about 40 MPH the entire electrical system shut off leaving me with no power steering. I was able to get off the road safely and call for a tow. I am second owner so warranty is out by about 2,600 miles. Dealer had I for a week at one point they said it was fixed when they were pulling it around front for me it stopped.
Takata recall: driving the car down a city street when it suddenly ceased to accelerate. The power steering stopped as it coasted into a side street to get off the busy road. I could smell wires burning as a electrical fire.I immediately got myself and family out of the car afraid it was on fire. The inside of the car filled with electrical smell and smoke. I called the 360 kia to have the car towed to the dealership since I bought a "gold" warranty when I purchased the vehicle they literally lost my car for six days and then called me wanting my service records stating the car had no oil in the motor. This is a outlandish lie! My car had plenty of oil in it ...I never saw a engine light come on indicating that I had motor problems nor did I smell oil . This was a "sudden " malfunction. My car never ran hot nor did my gauges ever indicate a problem. I had the car for right at 40k miles and had a oil change due again at the end of april.
