This is not quite accurate. #2 is the 2003 Honda Accord; #3 is a Sonata.

More importantly, it's not clear whether this site's methodology corrects for numbers of cars sold. Given that Honda accords and civics (and even the vaunted Toyota Camry) are in the top twenty worst list, my guess is not. In other words, high-volume models will generate disproportionate complaints b/c, well, there are more of sold. (Admittedly, the site says it also factors in cost of repair and average mileage of repair--but not volume.) I'm from Detroit, and as proud as I am of GM, I have to say I'm a little surprised they're not on the list anywhere.
The '02 Ex sold 434k units:
https://en.wikipedia.org/wiki/Ford_Explorer#Sales. The #2 "worst car," an '03 Accord, sold almost 400k units that year. Those are high volumes.
And while we all agree that the 4.0's timing chains are a concern (went bad on mine at 179k), I noticed that they did not even make the top five list of complaints for that year (no.7), and that there were literally 10x more complaints about the transmissions than about the engines.
Still, interesting data. They say that of the 39 timing chain failure complaints, the average mileage was 96k and change, and cost an average of $3,200 to repair. Good info.
I just like driving my '02 Ex, which feels great. My transmission has not burped in 185k miles and the rear hatch didn't crack, so I got that goin' for me . . ..
