Additionally, the contact stated while driving at approximately 10 MPH, the check engine warning light and several unknown warning lights illuminated, and the vehicle shut off. The contact shifted into neutral(N) and was able to push the vehicle to the side of the road with the assistance of several bystanders. The vehicle was towed to the residence. The vehicle was then towed to the dealer where it was leased, and it was diagnosed that the engine had seized and needed to be replaced. The engine was replaced; however, the failure persisted.

The contact stated that he turned off and restarted the vehicle; however, the failure persisted. The contact stated that he was able to continue driving using physical strength to steer the vehicle. The vehicle was taken to the dealer, who informed the contact that the earliest availability for diagnostic testing was September 8, 2023. The manufacturer was notified of the failure and informed the contact that they could not assist because the VIN was not included in a recall. …
Yesterday, [redacted], My 2015 kia optima engines reved up wothout me pushing the gas & within seconds later a loud noise and metal fell from under the hood. After pulling over, popping the hood on the passenger side and under the engine a fire had started. My daughter was seated in the back passenger side her door had locked, thankfully the passenger door was left opened bc within minutes the entire car was filled with smoke and engulfed in flames. Prior to this the steering wheel would jerk even while at a red light. This car just did have 100,000 miles & no knowledge this prior. Thank god i was able to get my daughter out of this vehicle & this didnt end in a tragedy due to negligence if this was a prior known fact.
I was driving on the Northbound side of the Interstate when my brakes failed when I pressed them to avoid a collision on the highway. The steering wheel malfunctioned when I tried to avoid a head-on collision with another vehicle. I couldn't control or stop the car, causing me to swerve left to right, and I then completely lost control of the vehicle. I crashed into the middle of the highway, but because my brakes had failed, the car continued at full speed into the Southbound side of the highway, causing me to wreck into a semi. The Colorado State Patrol investigated the accident. Right before I wrecked into the semi-trailer, I noticed all of the lights on the dashboard were off. My Steering wheel had fallen off completely, but the airbag never deployed even though every other airbag had deployed.
The contact owns a 2015 Kia Optima. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. Additionally, the steering seized. The contact stated that the steering wheel was difficult to turn, and the vehicle lost motive power. The vehicle was restarted; however, the failure reoccurred. The vehicle was towed to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 174,000.
The contact owns a 2015 Kia Optima. The contact stated that while driving at various speeds with the steering wheel in the straight position, the steering wheel experienced resistance when attempting to turn from the 12 o'clock position in either direction. The contact indicated that the resistance would suddenly cease causing the driver to over steer and potentially lose control of the vehicle. The cause of the failure was not yet determined. The local dealer was notified of the failure. The manufacturer was not contacted. The failure mileage was 34,000.
What component or system failed or malfunctioned, and is it available for inspection upon request? The defects involve multiple electronic control systems, including steering, braking, and airbag modules, which continue to generate active and stored Diagnostic Trouble Codes (DTCs) even after the May 2, 2023 recall repair. The vehicle remains in our possession and is available for inspection upon request. 2. How was your safety or the safety of others put at risk? Because the vehicle fails to illuminate dashboard warnings, we were unaware of critical malfunctions occurring in real time while driving. This creates the risk of sudden failure in steering, braking, or airbag deployment, directly endangering both occupants and the public. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. …
My 2015 Kia Optima has a failing ABS/HECU module consistent with the Kia ABS fire recall. The brake lights stay on constantly even when the brake pedal switch is unplugged. If I unplug the ABS/HECU module, the brake lights immediately turn off, which confirms the ABS module is back-feeding power into the brake light circuit. I also previously experienced the ABS pump running with the vehicle turned off. Currently the ABS, ESC, EPS, and Brake warning lights are illuminated and all stability/ABS functions are disabled. This is a clear safety hazard affecting braking, electrical safety, and vehicle fire risk. I have already been to the Kia dealer twice and they dismissed the issue after only checking the recall fuse. They refused to address the ABS module itself even though the vehicle is unsafe. The recall appears insufficient because the module has now failed. …
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.
2015 Kia Optima EX Steering column replaced under warranty at approx. 7,000 miles. Now at 99,500 I need a new Steering Column because of the same symptoms; STICKING STEERING. Steering wheel sticks when trying to maneuver towards the right. Then you over steer and need to pull back to the left. This goes on over and over at all speeds. The worst is at high speeds because the slight tug on the wheel makes you drift more because of your speed. Kia needs to recall all Optima's and re-engineer and replace their Steering Columns.
