Source: NHTSA Office of Defects Investigation, public domain. Complaint counts reflect what owners reported and are not a measure of failure rate per vehicle sold.
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.
If you arrived asking “is it reliable?” — this page answers the version of that question the data can support: which problems owners reported, and at what mileage.
How many miles does a 2006–2010 Kia Optima last?
Half of the failure reports on the 2006–2010 Kia Optima were filed by 68,000 miles and 90% by 134,000 miles — figures drawn from 700 NHTSA complaints that record an odometer reading, so they time reported failures, not the cars whose owners never filed one.
13 reports (1.9%) came in past 200,000 miles — each one proof a Optima reached that mileage, not that it died there.
Before you buy a 2006–2010 Optima: the 3-minute check
Generated from 700 mileage-tagged complaints, 3 recall campaigns, 2 documented problem areas. Print this page — the checklist survives print.
- Run the VIN at nhtsa.gov/recalls. 3 campaigns cover this generation; an open recall is a free repair you can make the seller's problem.
- Check steering. Electric/electro-hydraulic power steering column and motor faults causing intermittent loss of assist and noise.
- Check airbags. Clockspring failure disabling the driver airbag and horn; also Takata inflator exposure on later model years.
- End with a pre-purchase inspection of this car. Aggregate data describes the population; the example in front of you has its own history.
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 68,000. 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 64,000, 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.

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 64,000 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 68,000 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 23,000 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 67,000 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 90,000 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
What owners reported alongside the failure itself, out of 884 complaints against this generation:
- Crashes
- 66 (7.5%)
- Fires
- 26
- Injury reports
- 43
- Fatality reports
- 7
These flags are self-reported by complainants and unverified by NHTSA; one report can carry several flags, so the counts overlap and do not sum to a total. They are not adjusted for how many of these vehicles are on the road. No chart is drawn here on purpose: overlapping counts spanning very different magnitudes cannot be honestly encoded as lengths.
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.

The defect. Kia Motors Corporation (Kia) is recalling certain model year 2007-2010 Rondo, model year 2007-2011 Sedona, Sorento and Sportage, model year 2010-2011 Soul, model year 2008-2011 Optima, model year 2010 Forte, model year 2007-2009 Amanti, and model year 2009 Borrego vehicles. Originally, in April 2013, Kia recalled 623,658 model year 2007-2010 Rondo and Sportage, model year 2007-2011 Sorento, model year 2007 Sedona, model year 2010-2011 Soul, and model year 2011 Optima vehicles. In September 2013, Kia informed the agency that it was adding an additional 356,719 vehicles to this campaign. The
What can happen. Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of PARK without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
The free fix. Kia will send an interim notification to owners in May 2013. When parts are available, owners will receive a second notification and dealers will replace the stop lamp switch, free of charge. Owners may contact Kia at 1-800-333-4542. Kia's recall campaign number is SC098.

The defect. Kia is recalling certain model year 2006-2008 Optima vehicles manufactured from september 29, 2005, through june 13, 2007. There is a possibility that the shift cable may have been installed incorrectly, causing tension in the cable. If present, this condition could cause the cable to detach from the shifter assembly's dowel pin preventing the transmission from being shifted. The shift lever can then be moved into the park (p) position while the vehicle's transmission is still in the last used gear before detachment.
What can happen. If the driver leaves the vehicle without engaging the parking brake, there is a possibility that the vehicle can roll injure a person in its path or cause a crash.
The free fix. Dealers will inspect the shift cable and reinstall if necessary free of charge. The safety recall began on march 23, 2011. Owner may contact Kia at 1-800-333-4542.
