2013 Kia Optima Problems

the engine revs high and transmission wont shift and when you turn the steering wheel ya get a loud click and the steering wheels jumps

The contact stated that while driving the vehicle began to unexpectedly slow and then stalled. The vehicle was unable to restart. No warning lights illuminated. The vehicle was taken to the dealer where it was not diagnosed or repaired. The manufacturer was notified of the issue. The approximate failure mileage 215,000.

The contact owns a 2013 Kia Optima. The contact stated that while driving 30 MPH, the steering wheel was difficult to turn. There was an abnormal clicking sound coming from the vehicle and the vehicle was uncontrollable. The vehicle was towed to the local dealer, where it was diagnosed and determined that the coupling in the steering wheel needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and confirmed that there was no coverage under the warranty extension for the MDPS flexible coupling. The failure mileage was approximately 139,000.

Code : P1777 Transmission- oil pump A issue with the Valve cover gasket leaking into the engine causing a misfire. Making the car suddenly stop while driving which is very unsafe. I took the car to the dealership and they want to charge me for the repairs. I have 2 kia optima hybrid and both cars have the same issue around the same mileage. There were no warning lights during the time it was at the shop. I believe later down the line the engine will stall out and it should be fixed now while under warranty. However I received no help from the dealership unless I am willing to pay upfront. In addition to this there are electrical issues the front seats aren't moving immediately when the button is pressed. The steering wheel buttons barely work along with the radio. This is a huge problem that needs to be fixed.

My car started shutting down while driving. After the engine started seizing the key wouldn't turn in my ignition. Took car to dealership immediately on 10, 2026. Took again in 2024 for recall and other repairs. Found out after requesting previous service incidents they failed to do recall repairs and never notified me of it, or to come back. I've requested current diagnostic report several times in writing and verbally with codes for this current service, with non compliance. My car is still at the dealership needing work and I need current diagnostic report before I pay for repairs. I am attaching a dealership diagnostic e-Report for my 2013 Kia Optima from 2024. While the report lists “No Current DTC” for several systems, it also documents multiple “Communication Fail” errors across critical modules, including Smart Key, Head Lamp, Air Conditioner, Brake, and other systems. These communication failures indicate a broader electrical or network issue within the vehicle, not simply a failed battery. The report also shows that certain diagnostic scans were not properly performed. Additionally, there are historical fault codes related to TPMS and weight classification systems, further supporting that the vehicle has experienced ongoing electrical issues. Despite these findings, the dealership attributed the vehicle failure solely to a bad battery and did not provide a current battery diagnostic test. They also failed to address an open recall related to electrical/fuse issues prior to this failure. Based on this past diagnostic report, I believe the root cause of my vehicle’s failure is an unresolved electrical defect, potentially related to the outstanding recall, rather than normal battery wear. This has resulted in my vehicle becoming inoperable and poses a serious safety concern.

Paint began chipping/flaking off little by little everytime I washed the car. It’s a common occurrence with snowy white Kia paint in this year

I own a 2013 Kia Optima and I am experiencing recurring fuel system-related symptoms. The fuel gauge fluctuates even when the vehicle has a full tank of fuel, causing an inaccurate fuel level reading. In addition, the vehicle has begun to hesitate during operation, which raises concern that there may be an underlying fuel delivery or fuel system issue. I previously experienced a similar issue years ago, and I believe the vehicle was repaired during a Kia recall or service campaign. The problem has now returned, and I am concerned that the previous repair may not have permanently corrected the issue or that there may be a related defect affecting other vehicles. The combination of an inaccurate fuel level reading and engine hesitation could create a safety concern because the driver may not know the true amount of fuel remaining and may experience unexpected loss of power while driving. I am requesting that this issue be investigated to determine whether it is related to a previous recall repair, a fuel system defect, or another safety-related condition affecting the 2013 Kia Optima.

The vehicle is experiencing sudden engine stalling while in motion, a known safety hazard. Despite a documented maintenance history with no issues, the dealer (Bayside Kia) is attempting to deny a Theta II Settlement claim by shifting the narrative to 'engine sludge,' which only appeared as a symptom in June 2025( Walmart oil change) alongside engine performance issues. The vehicle has active codes P0014 and P0017, which are secondary symptoms of the internal bearing wear and metallic debris contaminating the oiling system. KDS Diagnostic tests showed Cylinder 1 at 0.16mm (approaching the 0.20mm failure limit). This clearance proves the connecting rod bearings are worn and reaching the failure threshold; this mechanical wear is the root cause of the engine's inability to operate safely. The presence of metallic debris in the oil is the definitive signature of the Theta II manufacturing defect. Furthermore, the dealer acted in bad faith by attempting to charge for Airbag repairs (Codes B1346/B1481) that are covered under the 15-year Clock Spring Warranty Extension (CS1102). The dealer has dismissed my qualifying maintenance documents, claiming they are 'not official,' which is a direct violation of the Magnuson-Moss Warranty Act. A manufacturer cannot deny a warranty claim because services were performed at third-party facilities, nor can they deny a claim without proving 'exceptional neglect.' I am reporting a refusal to honor a court-ordered safety settlement and an attempt to return an unsafe, stalling vehicle to the road.There is no evidence of engine abandonment or exceptional neglect. I’m considered "in compliance" if I can show I didn't go more than 14 months without servicing or a certain mileage between oil changes.The dealer's dismissal of verified third-party receipts and bank statements is a bad-faith attempt to ignore an inherent manufacturing defect documented by a 0.16mm BCT result and metallic debris.

I am writing to formally report a dangerous safety defect involving the braking system and the Hydraulic Electronic Control Unit (HECU) on my 2013 Kia Optima Hybrid. While operating the vehicle, severe warning lights illuminated on the dashboard indicating an immediate braking system and stability control failure. A diagnostic scan revealed active fault code C1237, pointing specifically to a primary pressure sensor signal failure embedded inside the internal HECU assembly.This issue presents a severe safety hazard. The failure compromises the vehicle's electronic brake assist, anti-lock braking system (ABS), and active stability systems. This results in unpredictable pedal feel and significantly increased stopping distances, drastically elevating the risk of a high-speed collision.Furthermore, this vehicle architecture relies heavily on clean voltage from the 12-volt battery system. Sudden drops in battery performance appear to trigger cascading communication faults within the HECU network, causing the vehicle to lose crucial safety systems without adequate warning.Kia is aware of severe electrical and internal component defects within the HECU modules of this generation, as evidenced by Safety Recall SC284 (NHTSA Campaign 23V652000) for HECU internal electrical shorts and engine fire risks. However, dealerships are treating related sensor failures inside the exact same HECU assembly (such as the internal primary pressure sensor) as customer-pay maintenance issues, rather than recognizing them as symptoms of a fundamentally defective or failing control unit. Dealership service centers are recommending piecemeal, expensive part replacements (like pedal travel sensors) that do not resolve the underlying safety risk of an internally failing HECU module.I request that the NHTSA investigate whether internal pressure sensor failures (Code C1237) and related electronic brake module collapses on 2011–2015 Kia Hybrid models are connected to the known sub-component defects wi

Brake pedal loses pressure and disengages with brakes. Traction light, maintenance light, hybrid system warning message, check brakes message and parking brake intermittently turns on and off. I called Kirby Kia of Ventura a few weeks ago and let them know about my issue with the car. I explained that I took the car to a mechanic and the diagnostic they did stated the issue with the car could be because of one of the recalls. On 4/10/26 I took my vehicle to Kirby Kia of Ventura for the recalls and asked if they could do the diagnostic. Raul from Kia was the service rep that spoke with me. He stated they would do the recalls and then, if needed, they would perform the diagnostic. Later that day Raul called me and stated the recalls were completed and no issues were found. Several items were found from Kia's point inspection, but none related to the issue at hand. I then asked Raul if they could perform the diagnostic to know what was wrong with my car and he stated that they could do the diagnostic on Monday, 4/13/26. Raul stated he would give me a call around 10 to 11 am, to discuss any issues. Raul called at 10:49 am, and stated no lights on the dashboard have come on and he didn't want to do the diagnostic because the lights weren't on. Kirby Kia of Ventura service department are crooks and only want to assist you if they get money out of you. My car still has the same issue, possibly damage to the HECU from the recall, but Kirby Kia didn't want to run the diagnostic on my car to find out if it was damaged. Kirby Kia of Ventura is a horrible organization and I will never purchase another Kia vehicle for this reason.

When I turned the ignition on the car wouldn't start. But the ABS light and all other lights flickering when trying to start the car. The alarm kept going off. Passenger side front and rear windows won't function. Smell like something was burning. This is the second incident ([XXX]). Fuses had to be removed to silence the alarms on the first incident on [XXX] because the lights were still flickering on and off when car wasn't on. I had my car serviced at the West Broad Kia Dealership in Richmond, Va. Thank you! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving my KIA Optima on the interstate the rear subframe suffered catastrophic structural failure, resulting in the steering wheel going out of alignment, the rear passenger side wheel tilting with the bottom of the tire being far out compared to the top. This resulted in the rear of the vehicle swaying side to side and being difficult to maintain in a straight path. This vehicle was previously serviced under KIA Campaign SC141 (internal subframe corrosion) at Griffin KIA on April 27, 2017. Despite this safety remedy being performed the subframe rotted through and snapped. This is a remedy failure. The anti-corrosion was applied by the manufacturer failed to prevent the exact structural failure it was designed to mitigate. I have physical evidence (Repair Order #92144) proving the remedy was performed and photographic/video evidence of the subsequent structural break. The manufacturer (KIA) has denied assistance, claiming the failure is "unrelated" to the corrosion campaign despite the part being the exact component covered by the campaign." SC141 involved the inject of wax into the metal components of the subframe of the vehicle and was KIA's response to the NHSTA's concerns about the metal components of their vehicles being unable to withstand salt in the Rust Belt states. The campaign only was for the vehicles in the rust belt states. KIA was very aware this was a safety issue and attempted to avoid a recall by issuing this campaign. The campaign failed and as a result my life was put at risk. I asked KIA for a good will repair of the rusted subframe but they refuse indicating the believe the part that clearly broke due to rust is unrelated to the safety campaign. Several of their employees stated it was very clear the part broke due to rust with one indicating he had a list of rusted parts needing replaced. I'd like the NHTSA to review this failed campaign and ensure the safety of all vehicles relying on this failed safety measure.

My 2013 Kia Optima sunroof exploded as I was at a stop, about to turn into work. I experienced a pop and had glass falling on me within seconds. There were no recent rock experiences and the road was completely clear. After dealing with the initial clean up, I drove to an auto glass shop to have it professionally removed. The glass was bowed and left with a large hole, almost like it had just exploded due to pressure or a faulty piece. I almost always have my daughter with me and I’m SO grateful she was not in the vehicle. This could have resulted in injury or even a collision due to the terrifying nature of glass shattering above you. My insurance does not cover comp, however I do work for an insurance agent and he did view the damage. No claim can be filed as the repair and replacement for the damage has to come out of pocket.

My sunroof exploded as I was driving my car down the road. It made a noise that sounded like a gunshot and I pulled into a parking lot and the whole thing was shattered. The sun roof is less than a year and a half old and there was no chips or cracks in it and nothing had fallen on top or damaged it.

I have been having electrical/lighting issues for about a year. It initially started with the inside lights intermittently flashing when opening the door or attempting to use the interior lights; however sometimes the automatic interior lights did not come on at all when set to automatically turn on when a door opened, but now the lights don’t come on at all when opening the door. I have also had some headlight and dashboard lights going on and off while driving. I have experienced this on at least 3 occasions since last June or July. I have done some of my own testing by switching the lights to different functions, on and off, etc. Because it has only happened 3 times I’m not sure exactly what the issue is and scared that at some point, they won’t work at all. This is very concerning and obviously a safety issue. In addition, just recently my interior speaker system began having issues when using the hands free call option. With every call I make or take while using the hands free option, the call goes in and out constantly and consistently. It doesn’t happen to those on the other end of the line. It does this every time for about the past month. The speakers work fine when listening to the radio. My phone works perfectly through the regular calling option or on the speaker option but that is not ideal while driving. As new issues continue to pop up, increase, progressively get worse, I’m concerned there could be other current or future electrical problems in the engine or in regular safe functioning of the car leading to melting, fire, or a malfunction while driving, causing catastrophic results.
