CarComplaints.com Notes: Although the 2003 model year is the "worst" model year for the 4Runner, it's not really bad at all -- mainly it's just that the other 4Runner model years are even better. Howver the 2003 model year has no major problems & no unexpected problems for a 17-year old vehicle. We award the 2003 4Runner our Seal of Awesome, since overall versus other comparable models of the same age, it's very reliable.
Initially the 4th generation (2003 - 2009) 4Runner didn't earn our top "Seal of Awesome" rating because it received poor crash test ratings for rear impacts. However it's proven to have one of the lowest driver death rates out of all vehicles (not just SUVs), so we've bumped it back up to our top award.
Sunroof gets stuck and makes a loud clicking/popping/snapping sound as the open/close button is pressed. This happened a number of years ago and estimates to fix/replace were in the thousands of dollars, so I unscrewed the window from the frame to find that a plastic piece attached to the track had broken in two. I was able to glue it back together, thoroughly clean the frame, apply white lithium grease, screw the window back on, and run the sunroof again.
I'm having the same stuck sunroof issue again and it's likely that the grease has dried out or gunked up with dirt/debris. I rarely run it anymore after the first time it broke down.
