By model year

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 67,276 miles; the figures below show which parts of the car run ahead of that and which run behind.

Visibility equipment accounts for 12.4% of complaints (240 reports, 164 of them with a mileage figure), with a median of 60,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 42,000 and 85,000 miles.

Throttle and speed control accounts for 11.0% of complaints (214 reports, 166 of them with a mileage figure), with a median of 50,740 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 24,000 and 90,000 miles.

The transmission and driveline accounts for 9.7% of complaints (189 reports, 136 of them with a mileage figure), with a median of 47,194 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 5,000 and 89,500 miles.

The engine and its cooling system accounts for 7.4% of complaints (143 reports, 126 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 40,000 and 111,400 miles.

The brakes account for 6.4% of complaints (125 reports, 81 of them with a mileage figure), and they fail late — a median of 129,000 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 90,000 and 169,563 miles.

The electrical system accounts for 6.4% of complaints (125 reports, 97 of them with a mileage figure), with a median of 79,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 39,050 and 120,000 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2006 model year drew the most — 346 complaints — while 2001 drew the fewest at 158. The median year sits at 316.

Recalls and what they cover

NHTSA records 7 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.

The campaigns cluster around seats (2), equipment (2), the engine and its cooling system (1). Repeated recalls against the same area of the car generally mean the first remedy did not fully resolve the underlying problem.

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 1,940 complaints filed against this generation, 243 reported a crash; 27 reported a fire; 159 reported an injury; 52 reported a fatality. Crash-involved reports represent 12.5% 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 33,000 and 107,578 miles, with a median of 67,276. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.

On inspection, visibility equipment and throttle and speed control are where this generation's reports concentrate, so those are the areas worth a specific look. Throttle and speed control in particular shows a median failure mileage of 50,740, 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.
