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 2,223 complaints with NHTSA about the 2003–2009 Kia Sorento, and 1,829 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 40,000 and 115,000 miles. The median is 79,400 miles.
The most-reported areas are the engine (11.9% of complaints, typically around 101,000 miles), the airbag system (11.7% of complaints, typically around 42,000 miles), the electrical system (10.2% of complaints, typically around 72,000 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 2003–2009 Kia Sorento last?
Half of the failure reports on the 2003–2009 Kia Sorento were filed by 79,000 miles and 90% by 143,000 miles — figures drawn from 1,829 NHTSA complaints that record an odometer reading, so they time reported failures, not the cars whose owners never filed one.
19 reports (1%) came in past 200,000 miles — each one proof a Sorento reached that mileage, not that it died there.
Before you buy a 2003–2009 Sorento: the 3-minute check
Generated from 1,829 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 suspension. Front lower ball joint and control arm wear on the body-on-frame chassis.
- Check transmission on 2003–2006 cars. Automatic transmission failures, particularly on the early 4-speed cars.
- Complaint reports are not spread evenly across model years here — see the by-model-year table below before you settle on a year.
- 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 40,000 and 115,000 miles, with a median of 79,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.
On inspection, the engine and the airbag system 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 42,000, 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 79,400 miles; the figures below show which parts of the car run ahead of that and which run behind.
The engine accounts for 11.9% of complaints (265 reports, 240 of them with a mileage figure), with a median of 101,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 74,000 and 128,000 miles.
The airbag system accounts for 11.7% of complaints (259 reports, 190 of them with a mileage figure), and it fails early — a median of 42,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 5,500 and 97,000 miles.
The electrical system accounts for 10.2% of complaints (227 reports, 175 of them with a mileage figure), with a median of 72,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 40,000 and 113,000 miles.
The engine and its cooling system accounts for 9.5% of complaints (212 reports, 189 of them with a mileage figure), with a median of 66,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 48,000 and 83,000 miles.
The transmission and driveline accounts for 8.5% of complaints (190 reports, 166 of them with a mileage figure), with a median of 63,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 20,000 and 101,000 miles.
The exterior lighting accounts for 7.6% of complaints (168 reports, 119 of them with a mileage figure), with a median of 53,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 26,000 and 97,000 miles.
Differences between model years
Within this generation, complaint volume is not constant across model years. The 2005 model year drew the most — 457 complaints — while 2009 drew the fewest at 79. The median year sits at 341.
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 2,223 complaints against this generation:
- Crashes
- 118 (5.3%)
- Fires
- 68
- Injury reports
- 85
- Fatality reports
- 6
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.

The defect. Kia Motors America (Kia) is recalling certain 2006-2010 Sedona and 2007-2009 Sorento vehicles. Moisture may enter the Anti-lock Brake (ABS) Module and result in an electrical short.
What can happen. An electrical short within the ABS Module may cause an engine compartment fire, even when the vehicle is turned off, increasing the risk of an injury.
The free fix. Kia will notify owners, and dealers will install a relay in the main junction box to prevent power from being directed to the HECU when the vehicle's ignition switch is turned off, free of charge. The recall began June 5, 2020. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC186.

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.
Sep 2011 · 2007–2008 · Air BagsThe passenger side air bag is turned off when the ocs misclassifies an adult passenger.
The defect. Kia is recalling certain model year 2007-2008 Sorento passenger cars manufactured from june 15, 2006 through november 27, 2007. The front passenger air bag may be turned off when an adult is in the passenger seat. The front passenger air bag is designed to be turned off in limited circumstances including when children and small adults are seated in the front passenger seat, there is a child restraint in that seat or the seat is not occupied. The vehicle's occupant classification system (ocs), which classifies the occupant in the front passenger seat, may misclassify an adult passenger as a
What can happen. The passenger side air bag is turned off when the ocs misclassifies an adult passenger. With the front passenger airbag off, the front passenger will not have the protection of the passenger air bags in some frontal collisions, thus increasing the risk of occupant injury.
The free fix. Kia will update the programming in the Sorento ocs control module at no charge. The recall remedy is currently available under service campaign sc076. Owners may contact Kia customer service at 1-800-333-4542.
