RE: 1998 GMC Jimmy SLS - Electrical & Coolant Problems

I have had several problems throughout the ownership of this vehicle.

I leased the vehicle new in 1998. Since that time, I have had numerous problems that began nearly right from the start.

One of the first problems I had was electrical. The interior dome lights would flash off and on repeatedly, either in the daytime or in the night, for no apparent reason. I could never make this happen when it was at the dealership.

Additionally, the windshield wipers occasionally do not work (they sort of work whenever they want to). This is also something that the dealership could never figure out and it continues now.

Approximately one year ago, I developed a slight overheating problem due to the DEX-COOL coolant that GM uses. The coolant developed an almost cookie-dough like substance which gunked up the entire radiator system.

GM would not stand behind me on this one either. At that time it had approximately 50,000 miles and the problem was supposed corrected with a radiator flush (which GMC would not pay for).

Now, at 60,000 miles I have had to have the alternator replaced. Furthermore, the compressor on my air conditioner just went out and had to be replaced at a minimum cost of $800.

I will never own another GM product due to the poor mechanics, electronic system, etc. of this vehicle. I hope that other owners are not "stuck" with these so called professional grade vehicles as I am.
