Replying to: pamcrabb (Apr 22, 2009 8:55 am) It is too bad a lawsuit is required when GMC knows they have a defect. Our Volvo had an issue and they voluntarily extended the warranty on the part to 10 years or 200,000 miles. Too bad GM does not get customer satisfaction or understand that you get customer loyalty if you stand behind your product. |

Hi everyone, My new 2009 5.3l Silverado has an erratic voltage display. When driving, the voltage gauge will move up and down from 12 volts up to 15 or 16 volts. I went to see the dealer and they told me that it was a normal operation and that the computer controled the charging. Is this true? He also said that should the light come on, I would then have to bring in the truck for servicing and to ignore the gauge. It's a trange thing seeing the voltage change that way. I've never seen this before unless there was a wiring problem. Any help/suggestion would be greatly appreciated. |

Replying to: canayjun64 (May 01, 2009 5:00 am) Since then, I have been very observant on what the battery has been doing...and SINCE I got the battery replaced, I have noticed the same as you...but have never had any other issue, so I assume that this is a normal thing. Normally I notice it most on the highway...but even with iPhone and GPS and any other crap plugged in, it's been fine. |

My Chevy has about 65000 miles and back in October my speedo went out. Dead. A month later the oil pressure gauge went, followed by the tach and today went the gas gauge. Sometime in November the radio started to cut out randomly. Usually when it cuts out the right green light on my rearview mirror turns red (the vertical one next to the Onstar buttons). When it cuts out the little red blinking security light comes on. If i turn the truck off and then turn the key to run it will come back on for a second and cut off again. Also randomly the lights in the power locks and windows go out, and they stop working. I only notice it at night when the lights are visible. Now that the gas gauge has gone out, if it wasnt for the Distance to Empty button on my steering wheel I'd be screwed. Anybody have ideas?
