“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.”
“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.”
“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.”
