Well I bought my 2000 Jimmy in Feb of 07, The gas gage never worked but I use my mileage to keep the tank gassed up. I have a hesitation when I take off like the truck will not want to speed up and it will do the same when I try to pass someone. NO POWER!! That is unheard of in the motor. I am now about to replace the drivers front wheel bearing. The brake lights on the rear sides have gone out but the top strip still works. I bought the truck used for 3000. It's a nice ride but now I am very scared after reading the blogs. Best of luck to all of us!

I have had the same problems as everyone else, thus the reason I found the site lol. I am now looking to replace the rear wheel bearings and seals (hopefully not an axle too).

Problems:

1) Key not releasing

Solution: Clean the button on the front of the shifter. It gets stuck and will not allow the relay to trigger to release your keys.

2) Front Bearings

I have replaced them every 40-50k miles.

3) Fuel Pump

All one piece for the fuel gauge too. Cannot be replaced separately. Compression ring was rusted also, and very hard to get on and off undamaged.

4) TCCM (Transfer Case Control Module)

It is behind the passenger kick plate and for some reason, commonly, has corroded connectors and board. It is about $700 to do. I replaced the pins myself and cleaned the connectors on the board. Works for now but the 4x4 still errors often.

5) Starting

Still working on this. The vehicle takes many attempts to start at times. After it is warmed up for the day, it starts easily.

6) Catalytic converter

Started breaking down. Loss of power due to restriction and rattling in the muffler from the junk blowing back into it. Change or fix permanently.

7) Rear bearings and seals.

Doing this today. Hopefully the axles are not scored. If so, I am junking this heap and buying my first foreign car.

Hope this has been helpful. email stryker777 at gmail dot com if you need any clarification of how I did some of the repairs.

I have a 1999 GMC Jimmy 4 door, 4wd. I purchased with a blown motor and replaced it myself. Since then I have put about 35,000 miles on it, replacing a lot of the above noted things.

I have yet to do wheel hubs/bearing, but am beginning to wonder if the current problem I have is due to that. If I drive my car 10mph or above, it makes a loud moaning sound from the passenger front footwell, although when selecting 4wd the noise seems to go away or become to faint to hear. When reselecting 2wd the noise comes back soon as the change has been made.

This problem started 2 days after replacing the heater core, although I can't see them to be related. The dash panel seems to function properly and no lights have been triggered. I NEED HEP ASAP!!! HELP ME!!

I have a 2000 GMC Jimmy, a 2-door with 100,000 miles. I bought it new. The similarities in issues are really odd. A year ago, the front-left ball joint failed while I was driving, instantly stopping the car, and shredding the tire like an onion. I also suffered a minor shoulder injury caused by the seatbelt (and I was only going 20 mph). I'm afraid of what could have happened if I were going 40 or 60 mph. Those 2 doors roll easily.

Other things replaced since:

Heater block

Fuel pump

Alternator

And oddly enough my passenger side seat handle broke off too, many years ago, as well as the vanity mirror covers.

Now, I was just told today the front wheel bearings are in danger of failing (hence how I found this place by googling front wheel assembly and Jimmy together).

I hate this car, and they wonder why GM and Ford are failing; this is why.

2000 Jimmy SLS, 174,000km.

Have just purchased it from dealer who had to do all of the above mentioned front end work, catalytic convertor, steel brake lines, front brakes/rotors to safety.

I have owned 4 wheel drives since 1985, and now expect the front end, U-joint, and all 4X4 issues mentioned. This is part of owning a 4X4, especially with a short wheel base.

The more torque the engine has, also increases the wear & tear on drivetrain components. Electrical issues with push button 4X4 are also common due to corrosion.

I know this doesn't help you folks that own these already, but to those who are looking at any small 4X4, be aware they have there own special maintenance issues.

I have a 2000 GMC Jimmy and it is a piece of crap.

So far I had to replace: tranny, battery, water pump, thermostat, radiator, ball joints, O2 sensors, head gasket, fuel pump, fuel injectors, shocks and much more.

Now I have to fix the 4x4 since it won't engage, it won't start when it's cold out, driver side window get stuck going up and down, 12 miles to the gallon and much more.

When I got it, it only had 45k miles on it and everything was working just fine. Then one day it was one thing after another, fix one thing and then the next thing goes.

GMC made a crappy truck. All these problems are happening from just normal driving? I think I just need to drive it down to the swamp and just let it rot.

I suppose if you drive like my grandma, you won't have any issues.

Her 2000 Bravada (same as a Jimmy) has been flawless since new until now at 89,000 miles when the 4x4 computer went out.

My grandparents make frequent trips to the beach, and the computer gave out while they were putting around in the sand.

They maintain it well, and it's been good to them.

I've owned my 2001 Jimmy since I bought it new. Currently 146K on it. Yes I have had some of the above said issues, including a lot of other repairs not listed, but my front bearings first went bad within the first 2 years of age. Under warranty I've had them replaced 3 times. Out of warranty so far only once. Been going strong ever since. Maybe because I didn't go to the dealer to have them done. I think after-market parts work better.

My biggest issue lately with my Jimmy has been the erratic fuel gauge, whiny fuel pump, and a horn that only seems to work during vehicle inspection "thank God" :-) Been this way for about a year now, except the horn.

Oh yeah since the get go.. my Jimmy always had this stinky exhaust, it comes and goes since I hit the 100K mark. I will admit it does get fairly good gas mileage, I average about 18-20 mpg hwy to & from work. Long travel I can get up to 23 mpg. Not bad I guess. Oh and I also use synthetic oil only 10w-30 Mobil 1. My engine runs so smooth.

I love my Jimmy...yes it has cost me a pretty penny in repairs over time... what vehicle hasn't?

I'll run my Jimmy till it falls apart & explodes.
