I own a 2000 Bravada. Decent vehicle so far. I work at a GM dealership, so I know about all the problems these have. Watch out for the sun shell, which is part of the transmission. These will go out, people don't diagnose it right, and you end up getting a whole new transmission. If you're a do it yourself kind of person, buy 6 quarts of auto trak II, flush the transfer case, refill it. Drive it for at least 5 miles of normal driving and sharp turns 5 mph or less. Then flush the transfer case again, refill and drive it. Check the fluid often. Check the fluid in your differentials often and top off with GM recommended fluids. All of this is preventative maintenance and really does help.
Fuel pumps are a known problem with all Bravada/Jimmy/Blazers. If it does go out, replace it with a GM one. If you go to a parts store and get one of course it will go out again. You get what you pay for.
These vehicles are leakers of everything, so I can't stress enough checking the fluids yourself and greasing everything yourself. Quick oil change places just stick the grease gun up there and pull the lever. They don't care if it's actually getting into the fittings. This will probably save you from ball joints and pitman arms.
Overall a good vehicle as long as you maintain it properly, and I would recommend one to anyone.
I have a 2000 Bravada 140,000 miles, bought new by my mother, daily driver till she got her Suburban 4 years ago.
Currently Smart Track won't engage, it tries to, but never works for more than half a second...
Also last year my rear suspension was sagging, and the car's overall ride was very rocky and felt unsafe. Since I brought it back out for the coming winter, I haven't noticed the rear sagging, but it is still very rocky.
Anybody got any ideas?
