This happens a lot. I was backing up out of my sister's driveway and when I hit the brakes there was a crunching feeling under my foot along with a weird sound like, "doing" at the end. I could not stop fast enough and ran into her brother in laws hitch on his truck with my right rear corner bumper cover. (if that's what it's called? Maybe fascia?) it didn't hurt his truck at all, but it sure busted up that corner piece real good on my Jimmy. It's been scary a few times since! I have had the brakes bled, and new brake pads installed, and it's still doing it! Also, the ABS light is on most of the time. When it's off is when this problem occurs. So I get a little panicky when that light goes off, although I'm pretty sure it shouldn't be on to begin with? I don't know what else to do about this except to contact someone about it. …

2000 GMC Jimmy experienced a problem with the front right hub and the wheel speed sensor. The consumer was pulling into a parking space and the brake pedal became stiff and or would not activate. The consumer had run into a brick wall and bounced into traffic. The check ABS system light had immediately illuminated. The consumer was then able to apply the brakes and backed into a parking space. The left front hub was replaced days before the consumer purchased the vehicle. The vehicle was also losing coolant. The consumer was informed that no coolant was in the vehicle.

On Wednesday June 23, 2004, I went to red holman Pontiac to replace a hub and bearing assembly on the front left wheel of my GMC Jimmy 2000. A grinding and metallic noise was coming from the front of the vehicle and I had to have done at the dealer. Two years ago, this same hub and bearing assembly was replaced at 48000 miles. Now, this vehicle has 75000 miles and I have to replace the right hub and bearing assembly. This means that this part only lasted 48000 miles and the replacement part less than 27000 miles. On both instances, there was also a failure of the ABS brake system. I have owned over the years more than 11 GM cars with various mileages at trading time and I never had to replace a bearing. …

1st 3 time now my check engine light went on for the samr thing secondary air injector system malfunction.it was just a bad sensor its still doing it.they want 140. Just for parts to fix it. 2nd I spent about 1000.00 to fix frount brakes rotors pads andwheel berrings.the owner of the garage said that he fixed about 50 of these a year my SUV was only 2 at the time 3rdi also spent almost 3000. 00 on a tranny last year because I lost all gears I only had drive.I had recomened the GMC Jimmy to at least 8 to 10 friends 7 bought them 5 have had the same problems as I have with tranny and brakes now my brakes are squeeking frount and back not grinding nothing wrong with back brakes ever had them checked they said they are fine.but very squeeky that is very annoying.when we lost reverce we was backing up and if the car behind us didnt back up we would have hit him.I thought I woul let you know …

On January 5, 2004 I tried to stop my 2000 GMC Jimmy (SUV), instead of stopping, the Jimmy picked up speed and resulted in a three car crash. Two of the cars (my Jimmy and a 1995 Mercury) were totaled and the other car (a Honda runner SUV)had damage totaling $11,000. Althought I was driving 35 MPH, when my car hit the car in front of it (the roasrunner), neither of the airbags in my Jimmy were deplyed. Luckily, no one was hurt in this accident. The mechanics at henderson Chevy in las vegas informed me that the ABS system failed miserably. As for the airbags, they did not have a clue. I contacted GMC and filed a formal complaint. Their investigators came to the dealer and authorized some work on the Jimmy so as to assess the damage and the reasons for the crash. As of this writing, I have not received any reports from GMC. …

Upon hearing the wear indicator on front brakes of my 2000 GMC Jimmy with 24000+ miles on it, I took it in for repair expecting only pad replacement and maybe machining of the rotors. As it turned out, all 4 rotors needed replacement due to large areas of deep corrosion that, according to the repair shop, was severe enough to affect braking, and thus, pad wear, leading to premature failure of these critical components. An attempt was made to machine one rotor to get past the corrosion, but the corrosion was too deep and would leave the rotor too thin. The repair shop is beginning to see this problem on late model GM vehicles, and as such, provided me with all the parts that were replaced (4 rotors and all pads) as well as an itemized list of new parts used in anticipation of some sort of follow-up action from GM or the government.

Many problems with this 2000 Jimmy. Bought it used from carmax at 18K miles on jan 2003, got ext. Warranty, but soon after, front brakes need to be replaced, replaced by carmax for free, but 6 mos later brakes needed replaced. Was advised that rear rotors and brakes were almost at end of life. 9 mos later, replaced rear brakes and rotors, not covered under warranty due to wear and tear, spent $450 as well as replacing serpentine belt and flushing break fluid, total cost $650. Problems with sunroof started in apr 2003, it finally stopped working and was replaced at 43K miles under ext warranty, had to get new battery, noise in under carriage on drivers side, determined to be problems with hub bearings and idle arm, inner tie rod, all replaced under ext warranty, total cost would have been $750.

Upon inspection of 2000 GMC Jimmy 4dr / 4wd brake line drivers side over frame next to fuel tank held down by a clip leading to rear brakes ruptured due to corrosion around the clip area that holds the line to frame causing total loss rear brakes and proper braking when brake pedal went to the floor while returning home to park vehicle at our residence,.. Luckily at time of incident we were on our own rural property in driveway which is (approximately 2/10 mile long) and not the busy main highway which was traveled at 55 MPH. The terrain was used in our driveway to bring the vehicle to a safe stop. Thankfully no injury's to occupants (including a 3 year old child) or damage to vehicle occurred with this incident.

My wife started the car and the red brakes warning light was on. She pumped the brake pedal and it went to the floor. She turned the car off and returned to the house and cancelled her scheduled appointment. Later, after I arrived home I inspected the brake lines and found evidence of leaking above the left rear wheel. I jacked up the car, removed the left rear wheel and a rubber shield between the frame rail and body. More evidence of a leak was present. I started the car, pumped the brakes twice, turned off the car and reinspected the area. The metal brake line that runs along the top of the frame rail had a leak where it 90s toward the center of the axle.

While driving my 2000 GMC Jimmy my girlfriend was involved in an accident. She came around a corner and had to come to a quick stop, when she hit the brakes the pedal went right to the floor and she hit the vehicle in front of her. After the incident I took my vehicle to my mechanic, and he found the stem that comes off the master cylinder had broken off. He contacted the NHTSA and the agent agreed with him that this part should not have broke off. My vehicle was damaged severely and if this part did not break and the parts worked correctly this could have been avoided.
