Never have had one on any of my cars, and in retrospect, I would have lost money if I had, these are bulletproof cars, even the way I drive them. 1 has 40k miles, 1 30k, 1 20k, nary a problem...
The only one that came close was the window regulator on the 2003, but even with my A/C issues I came out ahead on that one... It is nice having piece of mind however...
