2011 Kia Optima Problems

I own a 2011 Kia Optima, VIN [XXX]. My vehicle was taken to Rockwall Kia on August 25, 2026, for completion of NHTSA Safety Recall 23V-652 / Kia SC284TF involving the HECU fuse. The dealership replaced the HECU multi-fuse and label kit. Before the recall repair, the vehicle was operating normally. The same day I picked the vehicle up after the recall repair, the vehicle began dying while I was driving. I also noticed a burning smell. I returned the vehicle to Rockwall Kia. Their August 31, 2026 repair order documents my complaint and states that the vehicle would die while driving and that this problem “DID NOT BEGIN UNTIL AFTER RECALL COMPLETED.” The repair order instructs the technician to inspect whether the recall was completed properly and diagnose the concern. I am concerned because the HECU recall involves an electrical short/overcurrent condition and Kia's recall documentation specifically identifies burning/melting smell and smoke as warning symptoms. I am requesting that NHTSA document this complaint and review whether the post-recall stalling and burning smell could be related to the HECU recall repair or indicate a continuing safety problem.

I was having trouble with my left driver tire. 2 mechanics went to test drive the car to see what the problem was. As they were driving, the car died. They got it started but it ran horrible back to the garage. When they pulled in the driveway of the garage, the car started on fire. It was an engine fire but undetermined what exactly was the cause. The vehicle was looked over by the insurance claims adjustor. I am not sure if sluggish driving had anything to do with the fire. The car is totaled.

The contact owns a 2011 Kia Optima. The contact stated while driving 25 MPH, there was a notchy feel in the steering wheel. The vehicle was taken to an independent mechanic, where it was diagnosed, and the failure was linked to TSB Number: CHA060. The mechanic determined that the steering coupler needed to be replaced. The mechanic ordered the part for the repair. The vehicle was not yet repaired. The dealer was notified of the failure. The manufacturer was notified of the failure and informed the contact that the vehicle was not covered under TSB Number: CHA060; due to the mileage on the vehicle. The failure mileage was approximately 121,000.

1- Steering wheel. Yes 2- Not sure if something was going to happen while driving whether da or night or long distance traveling 3- I spoke with the service center a while back and didn't have a good time to bring it by. 4- No No just loud shaking from the steering wheel. It's been going on for at least a month

I have replaced the headlights in my 2011 Kia Optima multiple times but no matter what without the brights on, the road is not at all illuminated making it impossible to see at night. When you look at the car head on the lights look as if they would be incredibly bright, but I believe due to faulty reflective lining on the interior of the headlight housing, even though the bulb may shine brightly, it does not get reflected properly onto the surface of the road causing serious safety concerns.

After getting HECU recall done , it has caused issues with the HECU module to where the brake lights no longer work and the ESC light comes on the cluster panel. Up on reading the code C2130, it says Brake lamp relay error. Mind you that my car was in working order before this recall was even done. This a huge safety issue not having your brake lights work. I can get rear-ended and i have kids in the car. This has been a issue since July when i got the recall done and KIA has yet to find a fix for this matter.

The contact owns a 2011 Kia Optima. The contact received notification of NHTSA Campaign Number: 23V652000 (Service Brakes, Hydraulic); however, the part to do the recall repair was not yet available. The contact stated that while driving, the vehicle failed to exceed 60 MPH with the accelerator pedal depressed. No warning light was illuminated. The local dealer advised the contact that the vehicle could not be repaired due to a lack of maintenance records. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 160,000.

The car just keep doing weird stuff with the lights. It want go off all the time the key went work the cv joints are popping. Have to trigger the battery sometimes to start up

About six months ago, I lost the heated steering wheel functionality in my steering wheel, then from there, I slowly lost functionality like cruise control, and the most recent now my airbag and horn do not work. If you press on the horn, it is silent, and the airbag light has been illuminated consistently for the last couple of months. I had this issue diagnosed and it came up with the codes of B1346. And B1481. After some research, these issues are the result of a bad clock, spring and cause the airbag and horn not to work. Additionally, this issue is known to this model the 2011 Kia Optima, and has been recalled in most production cases of this vehicle, but my vehicle is not included. I received a quote for $876 from a dealership to get this corrected, but it should be included in the recall.

The airbag warning light on the dashboard stays on continuously and will not go off.

Hydraulic Electronic Control Unit (HECU) experienced an electrical short circuit and engine hardly running.

I could not brake and almost caused a car accident. Brakes gave out, no gas, it smelled like it was going to catch on fire.

While driving on the road, I came to a stop at an intersection. While waiting for the green light the engine stopped running. I tried starting the car by pressing the brake and the push start button and the car only clicked and did not start. I pushed the car off the road. After several attempts to start the car it wouldn't start and it started smoking it looked like it was coming from the starter location. It appears that the engine seized and it won't turn over.

While driving the Kia on the highway (in the passing lane on Route 93, Boston, MA), the hood of the car flew open and shattered the windshield. Prior to getting into the vehicle, there was no notification, warning light/display, that alerted to the hood or anything else not being 'closed', no rattling of the hood either. The hood blocked my entire vision with the exception of a small area below, where I miraculous got over to the breakdown lane without causing any accident. When I got out of the car, the hood was bent and the second latch was loose. It did not hold its shape. Called the police and the insurance company, the car was deemed a total loss. This incident occurred on January 31, 2026 at 10:05AM. The conditions were dry and sunny. The state trooper said that this incident could have had serious safety consequences to the driver and others since no one expects a hood to fly open, block visibility...this highway is a busy road and could have impacted several other vehicles on the road. We no warning lamps/message- this was traumatic- this put the safety of the driver and the public at great risk.

Paint is peeling off in large pieces despite there being no damage. We have the pearl white color.

I BOUGHT A BRAND NEW 2011 KIA OPTIMA HYBRID AND THE CAR PULLS HEAVILY TO THE LEFT EVEN ON STRAIGHT ROADS. I TOOK THE CAR TO THE DEALER AND THEY DID AN ALIGNMENT AND THEY SAY IT IS WITHIN SPECS BUT IT ACTS THE SAME. IF YOU LET GO OF THE STEERING WHEEL FOR A COUPLE SECONDS YOU'RE ON THE SHOULDER. THIS IS A VERY SERIOUS SAFETY ISSUE. SECOND ISSUE IS THAT BOTH DRIVER AND PASSENGER SEATS WERE BOLTED DOWN IN ONE BOLT OUT OF FOUR. THE DEALER INSTALLED THE MISSING BOLTS BUT THIS MAKES ME REALLY WORRIED ABOUT THE QUALITY CONTROL AT KIA. WHAT ELSE MIGHT THEY MISSED? I DON'T EVEN WANT TO THINK WHAT MIGHT HAVE HAPPENED HAD I BEEN INVOLVED IN A COLLISION BEFORE NOTICING THIS. UNACCEPTABLE! *TR

THE OWNERS MANUAL, SECTION 3, PAGE 8 DESCRIBES THE "FORWARD AND BACKWARD ADJUSTMENT" OF THE HEADRESTS IN THE 2011 KIA OPTIMA. THE HEAD RESTS DO NOT ADJUST AS DESCRIBED IN THE MANUAL. KIA CUSTOMER SERVICE EXPLAINS THIS AS A "TYPOGRAPHICAL ERROR." THE PROBLEM IS THAT THE HEAD REST IS DESIGNED SO THAT IT THRUSTS DRAMATICALLY FORWARD. IF THE SEAT IS SITTING UPRIGHT ONE MUST TILT ONES HEAD FORWARD TO ACCOMMODATE THE HEAD REST OR THE SEAT MUST BE LEANED BACKWARD SUCH THAT AN INDIVIDUAL WHO IS 5' 2" TALL CAN NOT SEE OUT THE FRONT OF THE VEHICLE. *TR
