2003 GMC Sierra - Random electrical failures in cabin
Strange electrical problems in my 2003 GMC Sierra 2500 crew cab. First thing that happened several months ago was the rear power door locks quit working - front work fine. A few months later, the rear speakers in the door quit working - front speakers worked fine. I figured it was something isolated with the rear doors. Next, the front drivers side speaker quit working randomely. It usually plays at a very minimal audible level (very low) and does not cut out completely - but randomly will work flawlessly. The next thing to go whacky is the "chime" for the headlights or key left in the ignition, etc. It will work sometimes, but usually does not. I think that when the chime works, the drivers door speaker works - but can't say for certain. Rear door locks and speakers don't work at all - not even randomly. I'm not a mechanic, but am hopeful that someone might have an idea of what I can check so I might save myself a huge repair bill. Thank you!

I've been a loyal Chevy owner for 40 years, and I can tell you I am insulted by their lack of support. I could live with one or two of these items, but looking at this list, COME ON!!! This truck is not abused; all regular service.
Anyone else out there experience such a nightmare??? At this point the next step would be.....
I see that you have already opened a Service Request with us, and am sorry to hear that the decision was unsatisfactory. If you were to send us your case number, we would be happy to look further into this for you.

Over the next several months, I began to notice erratic behavior with some of the gauges. The gas gauge, for example, would work fine some days but other times the needle would be in odd positions. Some of the other gauges would behave in similar fashion. I again went to the dealer and was told that, like the seat circuit, it could be difficult to trace the problem.
When I went to use the air-conditioner in the summer, nothing but hot air came out. Thinking that the system was low on freon, I again took the truck to the dealer. He found that the problem was in the heating controls, and that the heating circuit would not turn off. Again I was told that this would be an expensive repair and that they could not estimate a repair cost.
By this time, I am becoming aware that I have purchased a top of the line truck that has lost much of it's premium appeal due to significant electrical failures. There's more.
I go out one cold December morning to open the truck door, pull on the handle, and it comes off in my hand. I was standing on ice and immediately lost my balance and fell. I went to the dealer who immediately returns with the part. I asked if this was a common occurrence. "Yes, especially in cold weather," he replied. I'm 69 years old and have owned many vehicles in my lifetime. A door handle breaking off of a heavy-duty work vehicle is a bit surprising to me.
The final failure came as I was headed down a steep hill toward a red light at a busy intersection. I went to apply the brakes and the peddle went completely to the floor. I was 150 feet from the intersection and headed for busy morning cross traffic. Luckily, I remembered the emergency brake a came to safe stop. I had the truck towed to a shop. The mechanic knew exactly what the problem was without even looking. Apparently there is a problem with the brake line rusting out on this product.
I am extremely disappointed in this truck. I thought I was buying a top of the line work truck that over the past 18 months, has proven to undependable and now dangerous. I own a 1963 Dodge panel truck that still has the original brake lines intact and in good condition. The original door handles have not fallen off and all the gauges still work. It is apparent that poor design and component quality is a serious problem with GMC products. I will not be back as a customer.
If you're looking to do some DIY work on this, we hope you get some great feedback! Unfortunately, my access to technical information in limited; however, if you decided you wanted to get this checked out at a dealership and wanted for us to work with you through that process, please email us at socialmedia@gm.com with more information (including your name and contact information, a summary of the situation, the last 8 of your VIN and mileage, and the name of your dealership).
