So far we had the alternator go out at 101000 miles, and it already had a rebuilt one in it, so this is a concern.
After waiting 8 years for my first Tahoe and then needing to take it straight from the dealer on an emergency trip from California to Montana (3000 miles),we never had a problem. I am so impressed with it and it is so fast and strong.
Update to this entry at one year later, still a great truck, replaced fuel pump, and that's about it. Still pinching myself over this Tahoe, it is by far the best truck/car I have ever had, all I can say is WOW! Wonder if it stays this great due to the mild weather here in California, seems a lot of problems in the other reviews were due to severe cold and wet climates?
Hey, you think the 99' model is fast, just wait till you drive one of the new 07' or 08' Tahoe's, HANG ON TIGHT!!!
The new body styles suck and look like crap... compared to the 1999 and 2000...the curvy style by far is the best...
