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.

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.

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.

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.

Is 593 complaints a lot? They were filed between 2011 and 2026, roughly 38 a year, which is more than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.
