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.
While on mycarstats.com I noticed other complaints in regards to my 2000 GMC Jimmy jumping into 4 low. One person was told by the dealership this could not happen at a stop sign but it happens with mine a lot. The odd thing is we have noticed it happens the most frequently when the humidity is very high. If you are lucky enough to hear it switching you can try to continue moving and pushing the 2wd button frantically. If you aren't lucky enough to catch it, the vehicle has to be stopped completely, put in reverse and push the 2wd button continuously. Other times vehicle has to be shut completely off?? I too agree there is a safety issue with this when you can't go any faster than 5 MPH or need to put your car in reverse at a stop sign!!
I purchased a 2000 GMC Jimmy with 34000 miles on it and at 38000 miles the transmission failed. The sun shell granaded as the service people at GMC dealership put it. Now with 83000 miles the transmission did the same thing. Is there something wrong with the sun shells? Is anyone else having this problem. All of my miles are highway miles and I have all my maintanence records to prove that I do scheduled maintanence on my vehicle. I also do not abuse my vehicle and do not tow anything. I'll go broke if the vehicle requires a new transmission every 40000 miles. Each time it cost approx. $4,000.00 to fix. Can anyone help? Thank you
First the transmission went out and I had to have it rebuilt...then, I had to replace a ball joint...now the other one has to be replaced. The mechanic says it is too dangerous to drive. These repairs are not cheap and premature! Prior to having the transmission rebuilt I had it put on the machine and it sent out several different codes that had to be corrected...nevertheless, we still had to replace the transmission...also, the four wheel drive gets stuck periodically.
Vehicle goes into 4-wheel low drive when it is raining. Owner took the vehicle back to the dealer, who did a diagnostic, and told the owner that there was nothing they could do. This defect would have to occur while plugged into the diagnostic machine which was impossible. Took vehicle to another dealership on 03/05/2005, they plugged in and no code found in the computer. They also said vehicle would not go into 4 wheel low pulling up to a stop sign.
I have a 2000 GMC Jimmy 4wd. It has a hd towing package. At 84,300 miles my 4le60 transmission went out. The sun gear went bad. The sun gear is the main gear in the transmission. I have never raced the truck, or towed a trailer, or went 4-wheeling with it. I paid 1,400 dollars to have it rebuilt. By looking online it seems that this is a common failure to this transmission. What recourse do I have?
My 2000 Jimmy has oil leaking from the oil cooler hoses, this is a known issue on these vehicles. Where is the recall? Also, my gas gauge is displaying inaccurate readings. I hear this is also common on GMC Jimmy's. Where is that recall? Now to go along with my power window switch not working, molding coming loose, rear inside door handle breaking off, etc. All this with only 49,000 miles.
I put my 2000 Jimmy in reverse and heard a pop sound then it would not move at all so I put it in drive a it did move then but it wined so I had to call a wrecker to come get it.I bought it from a Ford dealer they said it was the valve body it would cost 650.00 to fix but I also but the extended warrenty but it was already out the said 4 out of 5 Jimmy have the same problem
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.
