Selected complaints filed with NHTSA by 2000 GMC Jimmy owners, lightly cleaned up (personal details are redacted by NHTSA).
My fuel gauge in my 2000 Jimmy began fluctuating wildly in januray 2008. When the tank was filled it registered fine but after some gas was consumed the gauge proved grossly inaccurate. I had to watch my trip odometer to gauge the amount gas left in the tank. I went to several mechanic's and was told that it was the sensor. However, from what I was told, the sensor and gas pump are both connected and submerged in gas. I had it repaired and luckily it was only the sensor. It cost more than $400. I was told that if the unit was severely corroded, I would have to replace both the pump and sensor. This is not a comforting experience. I assume there is no danger from fire, but I would expect the gas gauge to work and it didn't. I find it interesting that another person experience the exact same problem, only earlier.
Tl contact owns a 2000 GMC Jimmy. The contact stated that the spider port injector was leaking gasoline between the firewall and the engine. There was a recall for the previous year, make, and model vehicle, but not for the 2000 Jimmy. The contact smelled gasoline in the vehicle and took it to a personal mechanic. The dealer stated that gasoline leakage was a common failure. The contact feels that this is very unsafe due to the fact that gasoline leaking on a hot engine May cause a fire. The failure was noticed while driving 25 MPH. The current mileage was 115,000 and failure mileage was 93,000.
The gas gauge does not work once the amount of gas is below half a tank. I have a GMC 2000 model. There are many complaints about this on the internet, yet no recall. The gas needle either sticks, bounces around or shows a full tank when empty. I never know how much gas I have or if I will end up stranded on the road at night. I guess if someone has a deadly accident due to their vehicle cutting off due to an empty fuel tank with a gauge reading full in high speed traffic, someone will look at this widespread problem then. I hope that I am not that person.
For the past two years my 2000 GMC Jimmy has had continuous malfunctioning fuel gauge which is not reliable. The fuel quantity needle fluctuates and is un reliable. The dealer says the repair is expensive and is not covered, due to the vehicle being out of warranty period. The vehicle mileage is tracked to determine approx fuel quantity. I am submitting this report to urge the odi to effect a vehicle recall to fix this wide spread problem with the 2000 my GMC Jimmy vehicle.
I continue to have constant problems with my 2000 GMC Jimmy. First thing that happened was the gas gauge just started messing up. Giving false reading. I ran out of fuel two times because the gas gauge showed I had half of tank of gas and apparently it was empty. Leaving me sitting on the side of the road way out in the country. The second time this happened it cost me my current job. My employer did not believe that my gas gage would give such false readings!
I have a 2000 GMC Jimmy with 49500 miles. My gas gauge started to malfunction, and was displaying inaccurate readings. I was quite concerned since this was a fuel related problem. It turns out an electrical component in the fuel sending unit GM part number 25314231 had failed. From what I was told by the GM dealer, this component is submerged in the gas tank of the vehicle. I am reporting this to you for investigation as a possible safety related issue.
I own a 2000 Jimmy and have gone through 2 sets of upper and lower ball joints and at this time the left lower ball joints went again. What is the problem with the ball joints? This is costly to repair, as wel as dangerous, affecting the steering. I would like to know what improvments are being done to correct the problem, and if it is a common occurance among other GMC SUV's. There should not be disposible parts put on the front end of any vehicle.
Tl contact owns 2000 GMC Jimmy. The stated that while driving, the vehicle suddenly shut off because no fuel was being pumped in. The vehicle was towed to an authorized dealer who stated that the fuel pump was defective. The contact stated that the failure occurred several times. The vehicle was not repaired. The failure mileage was approximately 80,000 and the current mileage was 138,000.
The entire car is defective, though it does not state it is a lemon. I purchased it used. I have replaced many major parts that are not considered routine maintenance, such a driver's door hinges and bearings, hood release cable, steering arm (twice) hubs (twice) the wiring system is faulty. I have gone through 4 alternators in under 2 1/2 years.
Tl* - the contact owns a 2000 GMC Jimmy. The vehicle vibrated loudly when being started. The repair shop replaced the wheel cylinder for a third time. Also, the fuel sensor needed to be replaced. The failure mileage was 78,000 and the current mileage was 87,000.
