Few of us have owned enough of any car brand to make statistically valid generalizations. I haven't either, but here is my SUV/van experience.
Two "Toyota" models:
1. 1999 RX300 - had to go back many times for "debugging", but the dealer kept trying, apparently with factory help, and things eventually got fixed.
2. 2004 4wd V8 4Runner - one problem (the famous drivetrain vibration), many visits, and Toyota eventually decided to refuse to fix it.
Many Suburbans:
Most of them have been good. My 2004 has had one problem in 35000 miles, which was quickly and correctly repaired in one try. So far it has been a more satifactory purchase than the 4Runner, though it's not nearly as fun to drive. Incredibly, its highway gas mileage almost matches the 4Runner (and its computer is accurate, too.)
Two Fords:
1. 1990 Aerostar - a disaster!
2. 1992 4wd Explorer - still plugging away on rough ranch roads after 146,000 miles.
One Jeep:
1993 4wd Grand Cherokee - not great, but not too bad. A/C, Power steering, & transfer case repair. Sold at 122, 000 miles.
