3rd generation · XD (facelift XD2 from 2004) · 1,784 complaints, 1,257 with mileage
Owners filed 1,784 complaints with NHTSA about the 2001–2006 Hyundai Elantra, and 1,257 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.
This generation has two distinct failure patterns rather than one, which is the most useful thing on this page. 15% of failures occur before 12,000 miles, which looks like a manufacturing defect, and a further 26% occur after 100,000, which looks like wear. Two different problems share one name in the complaint data — and an average of the two describes neither.
The most-reported areas are the airbag system (27.8% of complaints, typically around 50,000 miles), the suspension (14.6% of complaints, typically around 92,000 miles), body structure (6.1% of complaints, typically around 79,117 miles).

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 66,026 miles; the figures below show which parts of the car run ahead of that and which run behind.
The airbag system accounts for 27.8% of complaints (496 reports, 347 of them with a mileage figure), with a median of 50,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 15,035 and 91,785 miles.
A single system taking 27.8% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.
The suspension accounts for 14.6% of complaints (260 reports, 207 of them with a mileage figure), with a median of 92,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 67,198 and 127,000 miles.
Body structure accounts for 6.1% of complaints (109 reports, 72 of them with a mileage figure), with a median of 79,117 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 57,000 and 120,000 miles.
The hydraulic brake circuit accounts for 5.6% of complaints (100 reports, 73 of them with a mileage figure), and it fails early — a median of 21,344 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 10,000 and 50,644 miles.
The exterior lighting accounts for 5.0% of complaints (89 reports, 63 of them with a mileage figure), with a median of 75,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 50,000 and 105,000 miles.
The electrical system accounts for 4.3% of complaints (77 reports, 56 of them with a mileage figure), with a median of 72,255 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 40,000 and 113,400 miles.
Within this generation, complaint volume is not constant across model years. The 2001 model year drew the most — 445 complaints — while 2005 drew the fewest at 180. The median year sits at 259.
The first year of the generation, 2001, sits above the median. That is a common pattern — early production of a redesigned vehicle tends to surface problems that later years do not repeat — and it is worth weighing when choosing between years.
No recall campaigns covering this generation appear in NHTSA's post-2010 recall file. That is not the same as an absence of problems — recalls address safety defects specifically, and many of the complaints above concern faults that are expensive or annoying without meeting that threshold.
Of the 1,784 complaints filed against this generation, 351 reported a crash; 26 reported a fire; 290 reported an injury; 3 reported a fatality. Crash-involved reports represent 19.7% 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.
For a buyer, the two-peak pattern is the useful part. The early cluster — 15% of failures below 12,000 miles — will already have happened on any example you are looking at today, and either been repaired under warranty or not. Ask what was done. The late cluster, 26% above 100,000 miles, is the one still ahead of you if the car has lower mileage than that.
On inspection, the airbag system and the suspension 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 50,000, 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.
