What this can and cannot tell you: these are complaints owners chose to file, not a failure rate. Popular models accumulate more of them simply by being common. How this is built.
Owners filed 884 complaints with NHTSA about the 2006–2010 Kia Optima, and 700 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.
Failures are spread across the mileage range, with the middle half between 32,000 and 99,000 miles. The median is 67,750 miles.
The most-reported areas are the airbag system (24.4% of complaints, typically around 64,000 miles), the transmission and driveline (11.5% of complaints, typically around 68,000 miles), the electrical system (9.3% of complaints, typically around 70,000 miles).
3 recall campaigns cover this generation.

Which systems, and when
Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 67,750 miles; the figures below show which parts of the car run ahead of that and which run behind.
The airbag system accounts for 24.4% of complaints (216 reports, 168 of them with a mileage figure), with a median of 64,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 15,000 and 89,000 miles.
The transmission and driveline accounts for 11.5% of complaints (102 reports, 85 of them with a mileage figure), with a median of 67,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 52,000 and 97,000 miles.
The electrical system accounts for 9.3% of complaints (82 reports, 67 of them with a mileage figure), with a median of 70,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 23,269 and 100,000 miles.
The engine accounts for 7.2% of complaints (64 reports, 49 of them with a mileage figure), with a median of 97,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 66,961 and 140,000 miles.
The exterior lighting accounts for 7.0% of complaints (62 reports, 42 of them with a mileage figure), with a median of 89,639 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 31,000 and 118,000 miles.
Throttle and speed control accounts for 4.1% of complaints (36 reports, 25 of them with a mileage figure), with a median of 70,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 40,000 and 90,000 miles.
Differences between model years
Within this generation, complaint volume is not constant across model years. The 2007 model year drew the most — 217 complaints — while 2010 drew the fewest at 99. The median year sits at 188.
Recalls and what they cover
NHTSA records 3 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.
Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.
Reported severity
Of the 884 complaints filed against this generation, 66 reported a crash; 26 reported a fire; 56 reported an injury; 13 reported a fatality. Crash-involved reports represent 7.5% of the total.
These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.
What this means if you are buying one
For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 32,000 and 99,000 miles, with a median of 67,750. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, the airbag system and the transmission and driveline are where this generation's reports concentrate, so those are the areas worth a specific look. The airbag system in particular shows a median failure mileage of 64,500, which gives a concrete number to compare against the odometer of any car you are considering.
None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.
Documented problems
Steering
Electric/electro-hydraulic power steering column and motor faults causing intermittent loss of assist and noise.
Airbags
Clockspring failure disabling the driver airbag and horn; also Takata inflator exposure on later model years.

What owners reported
I just purchased a 2006.5 Kia Optima. My concern is when my wife sits in the passenger seat; the air bag does not arm. Kia states that the new standard (NHTSA) states that one must be over 130 lbs. If true, i find that unacceptable. There is no statements within the owners manual or is there a placard on the…

We purchased a 2006.5 Kia Optima a few months back. This car is equipped with a feature, the de-activation of the front seat passenger airbag when the seat is vacant. My wife weighs about 104 lbs and does not always activate the switch as indicated by the fact the warning light does not go off, and therefore is…
