my gmc jimmy has been nothing but a problem since it hit 34,000 miles....anyone else have problems with theirs?

- the gas line broke

- a hole rotted through the gas tank as well (vehicle was 4 years old)

- when the wheels were taken off for a brake change, the backer plates -
crumbled and fell off ( vehicle was 3 years old at the time)

- ball joints and wheel bearings replaced yearly, sometimes within 8 or 9 months

- the 4 wheel drive went on it 3 times

- the rear passenger window won't go up, needs to be pulled up by hand

- the front driver's window won't close all of the time, only when it wants to

- brake line snapped

- the fan for the air conditioner and heater makes a loud roaring noise and
won't push air out of the vents on the driver's side

- a gasket busted

- sometimes you have to really press down hard on the door lock button a few
times for it to lock all the way

- the thermostat exploded and blew a hole in the radiator

- the floater in the gas tank floats all over and down to "low fuel" frequently, no matter how much gas is in the tank

- i've been driving with the check engine light on for 3 years--
per a few mechanics who looked at it, i was told to ignore it ...the vehicle is
driveable

the most frightening incident of all-------a year ago i was driving down the highway at 65 mph and lost all power.....the whole dash board went black and the vehicle just shut down........i tried to start it 4 times without success...

we had the vehicle towed and when the mechanic went to turn it on, it started with no problem........he went over it 5 times and found no nothing

anyone have problems with theirs or is this just a lemon?
i have 2 mechanics in the family that take care of the fluids etc.....it's not like it's neglected
