Seven problems related to alternator/generator/regulator have been reported for the 1997 GMC Jimmy. The most recently reported issues are listed below.
While driving vehicle stalled. Consumer was unable to restart vehicle. It had no power or lights, and was unable to be jumped start by another vehicle. It was towed to the dealer for inspection, and mechanic determined that the alternator and the battery needed to be replaced. Consumer informed the mechanic that this problem occurred more than once, and had not been resolved.
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.
The truck I have is 1997 GMC Jimmy 4x4 slt model I purchased the truck in 2000 knowing it was a pre owned vehicle for the first two years the vehicle was nice but the next two years I have have had nothing but troubles so far with this vehicle I have replaced 1) ignition switch that costed 700. Oo 2) pulley 3) alternator 4) heater core 5) compressor for a/c is gone havent replaced 6) fuel pump is gone havent replaced 7)winshield wipers work when they want to usual on clear days but when its storming they dont work which has resulted in me getting drenched 8) tailgate doenst want to go up I have had two years of problems with my truck and still contine to do so I purchased my truck with 21,252 mi and I now have 70,329 mi I need ball joints which I have not replaced in my opinion this is the worst vehicle I have ever ownmed and I believe ever made.
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. . .
Abs brakes failed, vehicle lost control, resulting in a head-on collision. Upon impact, driver's/passenger's air bags failed to deploy, resulting in injuries. In addition, ignition locked up/fuel gauge and alternator failed.
Alternator failed twice.
Alternator failed.
