Mar 2, 2024Steering

I am writing to bring a critical safety concern to your attention regarding my 2017 Kia Optima LX. The steering wheel of my vehicle frequently loses power, necessitating a restart of the engine for it to function properly again. This issue occurs randomly, but consistently takes place during steering wheel turns. On one alarming occasion while navigating a winding canyon road, the steering lost power, compelling me to slam on the brakes to prevent the car from falling off the cliff. Another incident occurred while making a right turn, resulting in me slamming on the brakes to avoid colliding with oncoming cars, narrowly escaping a potential rear-end accident. When the steering loses power, it remains functional but demands significant physical effort. Unfortunately, in attempting to steer during one episode, I strained a muscle, leading to a week of suffering. Despite the severity of this safety concern, Kia refuses to address the issue unless they can replicate it during a service visit. The problem occurs randomly, ranging from three times a day to once a month, with no warning signs prior to power loss. Kia has acknowledged this issue, evident in the warranty extension they provided up to 150k miles (attached). Regrettably, when I take the car to the dealership, they decline to address the problem due to an inability to replicate it. I believe this recurring steering malfunction poses a serious risk to my safety and the safety of others on the road. Your intervention in investigating this matter would be greatly appreciated to ensure the well-being of Kia Optima LX drivers. Attached, please find the mentioned warranty extension letter from Kia and an image displaying the MDPS warning light illuminated during instances when the steering lost power. Thank you for your prompt attention to this urgent matter. The contact stated Kia inspected the vehicle but was unable to replicate the issue during their inspection. However, they recommended replacing the assembly column as a potential solution, but the contact declined due to lack of assurance that the assembly column replacement would resolve the issue.

Feb 23, 2024Lights

I drive with my lights on auto. Occasionally the lights go out for no apparent reason. Both inside and headlights. I then have to hold the high beam switch on until I can turn lights on and off or use directional. Sometimes using the directional will cause lights to go out as well. This can happen several days in a row or maybe once or twice a week. I have noticed a few times the box appearing in my dashboard saying lights were off. I had done nothing for them to go out. If a cop sees this happen I am sure to get pulled over. This has been going on for a year=3 trips to 2 different dealers. I brought my car to two different dealers and they both said without it happening when they have it they cannot do anything. I do not understand how a few years ago they fixed something incorrectly and I had to go back for a different part. Apparently this can't be done for this. So, I just risk my life every time I drive at night!!

Every time after I get an oil change I’m constantly having to put oil in it because it goes dry every 2 days and my check engine light stays on before and after oil change, randomly shaking soon as I turn the car on then the oil light comes on every time I go over a speed bump! The car slams on breaks when it wants and has even did it when in fast traffic on the highway.

Feb 14, 2024Engine

I was driving at 65MPH on the highway when the warning lights went flashing on my dashboard with "Check Hybrid system", "!HEV", and check engine light. I pulled over to the side of the highway and had a tow truck took it to the dealership to check out. Kia dealership did a diagnostic and mentioned the hybrid engine failed to convert from hybrid to gas and vice-versa. I am at 165,531 miles and Kia is charging me $13,000 to fix it. I am over the warranty of 150,000 miles. The "Check Hybrid system" message has been ongoing since 2021 and Kia mentioned it has to do something with the hybrid battery and Kia no longer makes a replacement battery for the Kia hybrid optima 2017. All Kia does it reset the system for the "Check Hybrid system" message to go away. After a few weeks, the message will appear again on the dashboard. I have upload an image of the dashboard with all of the warning lights. I need help as this is costing to much to fix.

This has happened several times to me! While driving the steering wheel locks up and I have to coast to a stop to turn off the engine to reset the wheel. It has happened going 60mph down the hwy with my 3 young kids in the backseat. Going 30mph and I have almost hit two cars because of this. If I couldn't stop in time and time hwy wasn't a straight road we would've died. The part I need for the car has been on a back order for over a year. Kia said its not that big of an issue but my life and my kids life is at risk every day!!! Please help!!! This can't only be happening to my car!!!

Driving down the interstate, the vehicle started to decelerate and the engine light started flashing. Got it to a mechanic and he started that it was a knock sensor failure P1326 code. Same as the recalls, but my vin number was not included in the recall report. Already had this vehicle in for excessive oil consumption. Paid for the dealer consumption test. They said it only burned a qt. and that was acceptable. In 1000 miles. Have done my own 1000 mile test and have been burning 1.5 or more qts. on three separate tests. Something has to be done about these engines. This is dangerous when going interstate speed and dropping to 20 mph in heavy traffic.

The engine on this vehicle caught fire while the vehicle was parked and not running. It had previsouly been drive for approximately 4 hours throughout the day but at the time of the incident there were no warning dashlights present. It is currently available for inspection, however depending on the length of this invesitagion it may no longer be available as i work with my insurance company determing next steps. My safety and the safety of other were put at risk by and open flame and smoke that occured during the fire. Ultimately the Fire Department were required to put out the fire. Approximately 8 months ago the engine was replace by the dealership Summit Place Kia East in Michigan due to an open recall for a knock sensor issue. I suspect this vehicle will be a total loss.

Oct 1, 2023Engine

Complete engine failure while driving 70mph down the freeway. No lights came on before engine started shaking, knocking, and failed. We were stranded at a gas station. We checked oil and there was none. (This was shocking because we changed oil regularly and car had just received complete oil change several weeks prior) We bought enough oil to drive it to nearest auto mechanic shop. He inspected the car and said complete engine failure and that we needed to contact KIA immediately. Spark plugs were burnt and melted more than he had ever seen. He said this is a recurring problem with their engines. (A few months prior to this incident, check engine light came on and car had a slight sputter during acceleration. We took the car to local repair shop. Car received complete tune up weeks prior to incident and check engine light was resolved.) Car was taken to Kia dealership in Little Rock, AR. Diagnosis: Major oil consumption caused engine to overheat and lose pressure/fail. Engine is non-repairable. New engine will cost $10,000. Kia will not back their product. After investigating further, I have found a Facebook group with tens of thousands of people with similar incidents in their Hyundai/Kia cars. This is a dangerous problem and KIA needs to be held accountable. The most recent class action settlement DOES NOT cover engine failure due to major oil consumption, only rod bearing failure. Where is the oil going? There were no leaks detected, no oil light to warn me. Where does the oil go? Burning up through exhaust? Surely that violates some sort of environmental standard that car manufactures should be abiding by. These cars are dangerous to consumers, and bad for the environment. I’m stuck with a car that I still owe money on that is worthless. If I spend $10,000 to repair, they will put the same engine back in the car and I will repeat the cycle of engine failure and loss.

Oil burning faster. After an oil change I go about a month before I have to add more oil again. There is no leak as every time I get an oil change I make sure they check. But around the month period I have to check to see if I am low on oil again. Very frustrating and starting to become costly

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2017 Kia Optima verdict →
