Drive an 1998 GMC Jimmy with around 172,000 miles on it (I know this is a lot of miles). Had the local gm dealer work on my rear defroster (one of the clips fell off). After receiving the vehicle back from the dealer I turned my defroster on about two weeks later. The back window exploded like a shotgun after about 15-20 seconds. Dealer says rear defroster voltage regulator must have went bad. I argued that a fuse should had blown before an explosion took place. Gm complaint department also disagrees, saying that the vehicle is old and things like this happen. Luckily, no one was standing by the rear window when it exploded because it probably would have killed them. If I'm wrong tell me I'm wrong but I believe gm is responsible for no only replacing the window but fixing the rear defroster voltage regulator. I hope this is an isolated case but maybe by reporting this I can prevent someone from getting hurt (including a gm technician).

I bought a 2000 Jimmy from oak motors. I have had it for 5 months. In the last 5 months I have replaced the alternator, 3 pulleys, serpentine belt. The brakes are going out, power steering is going out, engine is tapping. I took it back after having it for 10 days because the service engine light came on. They wanted 175. 00 to look at it. I was told at the time of purchase that I had to purchase the warranty for 995. 00, I thought this was to cover any problem with the vehicle. It doesn't. They now want 540. 00 to fix it. Please help.

Transmission failure / replaced transmission - upper & lower ball joint failure / replaced upper & lower ball joints - rear window wiper failure / inoperable at this point - extremely expensive replacements with no old parts available at this point. Events leading up to failure I can only attribute to severely poor manufacturing of products, there was no operating misuse or abuse. Also other parts that have failed and have since been replaced are the: alternator, fuel pump, fuel pressure regulator and cooling system failures.

I have gone through 4 alternators in under 2 1/2 years.

I have a 2000 slt Jimmy which has been a pain. I've had lower ball joints replaced, upper ball joints replaced, major problems with the brakes, u joints replaced, hub and wheel bearing problems, altenator failure, a/c blower motor replaced, broken blend door which caused encoder motor and module failure, rear wiper moter replaced, back window lock replaced. Too many things have gone wrong with this vehicle. GMC should consider some sort of recall because I've read many complaints regarding some of the same issues.

This car has continually had transmission problems. I have also stopped in the dealer on 2 separate times about the transmission. The mechanic hooked up a computer to see the problem. I was never given a work order sheet for those 2 times. It has also been recalled for seat belts & ignition switch. Mr.

This vehicle has been a nightmare. . . Unfortunately it was a spur of the moment purchase. Although used, with only 39,000 miles, I thought I would be ok since it had an extended warranty till 72,000. I have replaced both upper and lower ball joints, idler arm, alternator, belt tensioner, ignition switch, 4wd sensors, gas gauge sensor, left rear axle shaft and both rear axle bearings. At least these were all covered under the warranty, but not the rental cars for all the time the truck spent in the shop. Now the vehicle has 90,000 miles and the dealership is telling me that the recall for the ball joints does not pertain to my truck (the VIN # is not included), the transmission dipstick is rusted (I've seen several complaints but no recall), my accelerator pedal sticks severely (also numerous complaints), and I've already replaced (out of pocket cost of $1700) a complete rear end. I owe more than this vehicle is worth. . . But will need to get rid of it soon because I do not feel safe driving my son around in it. Many of these problems could have caused a serious accident. . .

I would like to suggest that the entire 1996 GMC- Jimmy series made need to be recalled because the owner has to many repairs to be done on the vehicle. The services engine light comes very often to indicate repairs on the truck and their are to be problems with this 1996 Jimmy. I suggest a total recall of this vehicle and this vehicle is unsafe to be on the road. It has a very bad braking system abs.
