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 3,909 complaints with NHTSA about the 2006–2010 Hyundai Sonata, and 3,175 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 102,000 miles. The median is 70,000 miles.
The most-reported areas are the airbag system (22.8% of complaints, typically around 70,000 miles), visibility equipment (8.8% of complaints, typically around 61,000 miles), body structure (7.4% 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 70,000 miles; the figures below show which parts of the car run ahead of that and which run behind.
The airbag system accounts for 22.8% of complaints (893 reports, 707 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 36,000 and 100,338 miles.
Visibility equipment accounts for 8.8% of complaints (343 reports, 294 of them with a mileage figure), with a median of 60,906 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 41,000 and 72,300 miles.
Body structure accounts for 7.4% of complaints (288 reports, 245 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 46,000 and 91,232 miles.
The electrical system accounts for 6.3% of complaints (247 reports, 195 of them with a mileage figure), with a median of 80,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 55,000 and 115,000 miles.
The engine accounts for 5.6% of complaints (218 reports, 182 of them with a mileage figure), and it fails late — a median of 106,000 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 72,000 and 130,000 miles.
The brakes account for 5.2% of complaints (204 reports, 169 of them with a mileage figure), with a median of 73,250 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 54,450 and 106,000 miles.
Differences between model years
Within this generation, complaint volume is not constant across model years. The 2006 model year drew the most — 1,422 complaints — while 2010 drew the fewest at 415. The median year sits at 612.
That makes 2006 an outlier: roughly 2.3 times the median year of this generation. A single year standing that far apart usually reflects either a first-year issue that was later corrected, or a component change introduced for that year. Anyone shopping this generation has a straightforward reason to prefer a different year, all else being equal.
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 3,909 complaints filed against this generation, 176 reported a crash; 64 reported a fire; 162 reported an injury; 4 reported a fatality. Crash-involved reports represent 4.5% 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 40,000 and 102,000 miles, with a median of 70,000. 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 visibility equipment are where this generation's reports concentrate, so those are the areas worth a specific look. Visibility equipment in particular shows a median failure mileage of 60,906, 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
Engine
The 2.4L Theta here is the port-injected version, NOT the Theta II GDI. It has no connecting-rod-bearing recall history — an important distinction from the 2011+ car that shares the '2.4 Theta' shorthand.
Airbags
Occupant classification / passenger airbag sensing system faults leading to non-deployment conditions; subject to campaign action.

What owners reported
This complaint applies to a 2007 Hyundai Sonata limited (no option for 2007 was available in drop down menu) (issue 1) at or around the initial few days after taking delivery i began to notice abrupt vibration and shaking coming from the steering wheel; substantial enough to feel in the seat. Vehicle was taken back…
