Expert Answers about Kia Optima


  • Can 2 e-Bike Rack Be Used on 2012 Kia Optima
  • As you probably noticed, there are only two trailer hitches available for your 2012 Kia Optima and both are Class I models with a 1-1/4" receiver. Between the two options I recommend the Curt # C11025 because of its superior powder coat finish that will do a better job of resisting rust and corrosion over time. Trailer hitch manufacturers typically try to match up the hitch size/capacity to the capacities on the vehicle(s) they are designed to fit. This helps to keep customers from potentially...

  • Correct Wiring Harness and Troubleshooting Harness for 2019 Kia Optima
  • The first thing to do is check to ensure you have the correct harness because a 2019 Kia Optima has two different harnesses depending on which model you of Optima you have. For EX and LX models you need T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118453. As of 8/23 we do not have a harness for the SX models, you would need to recheck our fit-guide at a later date or contact the dealer. There are some troubleshooting steps you are going to need to take to figure...

  • Recommended Trailer Hitch for a 2018 Kia Optima Plug-In Hybrid
  • The best trailer hitch we have for your 2018 Kia Optima Plug-In Hybrid is the Curt Trailer Hitch Receiver part # C11402. This hitch is a custom fit that installs using pre drilled holes in the frame rail. If you will be using this hitch for a bike rack or cargo carrier then you should also use the Curt Cam Buckle Stabilizing Strap part # 18050 as this is going to help support the accessory and place less stress on the vehicle. If you do not want to use the Curt Cam Buckle Stabilizing...

  • Roof Rack Fit Recommendation for 2017 Kia Optima
  • We have Rhino Rack roof racks that fit your 2017 Kia Optima, but the square bar setup you mentioned is not a fit. Instead you'd want the Rhino Rack part numbers # RRVA126B-2, # RRRLKVA , and # DK436 which is a confirmed fit and would work well.

  • Differences Between Draw Tite Hitches for 2013 Kia Optima
  • While very similar there are few key differences between the two Draw Tite hitches that fit your 2013 Kia Optima. The part # 24965 costs less but has a more in-depth install which requires underbody panel trimming/removal. The part # 24853 will install in almost half the time and does not require trimming of underbody. I attached install videos for both hitches as well.

  • Engine Block Heater fit for 2015 Kia Optima with 2.4L Engine
  • You are correct that the Kat's Heaters Custom Fit Engine Block Heater # KH11812 is a fit for your 2015 Kia Optima with a 2.4L engine. It will be installed in the "2nd RR" position as you can see by the accompanying photo of the directions I cut out for you. In terms of the grease, you should only use what was recommended by the manufacturer. If you use the term "G624" in a search engine you should be able to find this grease pretty quickly.

  • Troubleshooting Trailer Wiring on 2009 Kia Optima that Stops Working When Plugged into Trailer
  • I spoke to my contact at Curt and after I explained to him your situation he said the problem is either you are overdrawing the converter box of the # C56049 or are overdrawing the taillight circuits of your 2009 Kia Optima. His advice was to convert your incandescent trailer lights to LEDs as they draw considerably less which should fix your problem. I attached a link to the right that has all of the LED trailer lights we offer.

  • The door clamp style of roof racks like the Inno part # INB137, # INSUT, and # INK685 do not allow water to leak into the vehicle. If you check out the picture I attached you can see that the clamp actually fits above the door seal.

  • Troubleshooting Trailer Wiring Harness on 2009 Kia Optima
  • What kind of tester are you using? I'd use an incandescent bulb tester like part # PTW2993 on the vehicle trailer connector while each function is activated. Turn on right turn signal, test pin fed by green wire. Turn on left turn signal, test pin fed by yellow wire. Turn on running lamps, test pin fed by brown wire. Applying the brakes should cause the pins fed by the yellow and green wire to show voltage. If you're showing power on the appropriate pins as each function is activated,...

  • Comparing Draw-Tite Trailer Hitch Receiver # 24940 and # 24965 for 2016 Kia Optima
  • The Draw-Tite Sportframe Trailer Hitch Receiver 24940 and # 24965 both will fit 2011 to 2017 Kia Optima models. The only difference between them really is that the # 24965 will also fit 2018 Hyundai Sonata's excluding the hybrid as well where the discontinued part 24940 only fit Sonata models through 2017. There is no difference for your 2016 Kia Optima, so I recommend the less expensive of the two. If you will be using this hitch receiver for towing, I recommend the ball mount # 3593...

  • Trunk and Hitch Mounted Bike Rack Options for a 2012 Kia Optima
  • The Thule OutWay bike racks, # TH45JV, # TH56BV, and # TH65JV are excellent bike racks with many great features, but they are a little pricey. Another bike rack that you may be interested in from Thule is the Archway 3 Bike Carrier, # TH9010XT. This bike rack uses 4 rubber pads that rest on your vehicle to prevent scratching or damage to your vehicle. This bike rack will fit on your 2012 Kia Optima and gives extra room underneath to accommodate for a factory spoiler. You may also want...

  • Hitch Options for a 2021 Kia K5
  • For your 2021 Kia K5, you will need the Curt # C58JR. The Curt # C11402 you looked at is specific to the Optima line as the 2021 K5 is wider, lower, and longer than the 2020 Optima, so the hitches are quite different between the 2 vehicles.

  • Trailer Hitch and Towing Equipment for 2011 Kia Optima Hybrid
  • According to Curt, their Class I hitch, part # C11025 fits all models of the 2011 Kia Optima, including the hybrid. If you'll be towing with the hitch, you'll also need a trailer wiring harness, a ball mount and a trailer ball. For a wiring harness, use # C56314 and for a ball mount, use # C45521. For a 1-7/8 inch trailer ball, use # A-80 or # A-82 for a 2 inch ball. I've linked you to install videos for the hitch and the wiring harness.

  • Roof Rack For 2017 Kia Optima SXL w/ Panoramic Sunroof
  • I do have some roof rack options for you that will work with your 2017 Kia Optima SXL, but the Sport Rack option your looking at # SR1010 is not going to work. You have many different manufacture options for roof racks but I suggest getting the Rhino-Rack Vortex Aero Crossbars # RRVA126B-2, the Rhino-Rack 2500 Series Legs # RRRLKVA and the Custom DK Fit Kit # DK436. These are about the same size of the sport rack option you were looking at but the aerodynamics of this style bar will be...
