Engine
614 reports12 crashes88 fires
“The contact owns a 2013 Kia Optima. While driving at 65 MPH, the vehicle lost motive power but continued to drive under reduced power, with the check engine warning light illuminated. The failure nearly caused a crash. The vehicle was taken to O'Reilly's, where three knock sensor codes were retrieved. The vehicle was then taken to the dealer and was repaired under NHTSA Campaign Numbers: 23V652000 (Service Brake, Hydraulic), 22V093000 (Fuel System, Gasoline), and 22V560000 (Structure). The manufacturer was notified of the failure by phone. The failure mileage was approximately 125,055.”
Steering
213 reports6 crashes1 fire
“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.”
Electrical system
146 reports5 crashes21 fires
“Module 1 7.5 amp fuse continues to short and blow over and over again. Known issues with auto headlamp leveling sensor. Problem continues to happen. Lose my highbeams, shift lock, rear defrost, rearview auto dimmer, steering wheel controls. Anytime the fuse blows”
Structure
127 reports5 crashes11 fires1 related recall
“The computer modular or engine control module yes, it is available for inspection. I can be at risk because my lights flicker off and, on my turn, signals do not work, and it will not go into drive I have to start my car 30 minutes before I can leave for work at 5:30am in the morning. I had a security update on my car and ever since that took place, I had this issue. I just had the P1326 code come up on my car last November took it to Vero Beach Kia and had that update done on my car for the engine problems that is going on, and they replaced the last recall which was the knock sensor. I had explained to them the issue my car does when starting it they told me it has nothing to do with the update that would cause it. When looking this issue up there are other people having the same issue, but Kia will not inspect it out so can you please investigate this issue and plus the paint on my car has peeled so bad.”
Fuel/propulsion system
94 reports1 crash10 fires
“Despite documenting this catastrophic internal mechanical destruction, the authorized franchise dealer has issued a written directive instructing the driver to operate this structurally compromised vehicle on public roads for a 1,000-mile oil consumption test with explicit instructions not to add, check, or have anyone service the engine oil level. Operating an engine running dry with verified cylinder wall gouging and unstable timing chains creates an imminent, severe safety hazard for the occupants and other motorists, including sudden highway engine lockup, loss of power steering, or vehicle fires. The vehicle underwent Safety Recall Campaign SC147 in 2017, which carries a court-mandated Lifetime Warranty Extension on the block for core failures. The dealership is forcing an unsafe vehicle modification and dangerous roadway test to evade standard warranty coverage processing. A complete 11-invoice history proves this defect originally manifested and was logged by a technician at 96,738 miles while fully inside the standard factory coverage window.”
Power train
64 reports3 crashes1 fire
“The contact owns a 2013 Kia Optima. The contact stated that while a family member was driving the vehicle at 40 MPH, the vehicle stalled. There was no warning light illuminated. The driver pulled over to the side of the road where the vehicle failed to restart. The vehicle was towed to the residence, where an independent mechanic diagnosed the vehicle and determined that the engine and transmission needed to be replaced. The vehicle was not repaired due to the cost. The dealer and the manufacturer were not contacted or notified of the failure. The failure mileage was unknown.”
