My 2004 Avalanche started making knocking sounds when turning corners - took it to the dealer and $700 later and a new steering yoke the knock was squelched (not gone) and the speedometer coincidentally started moving like a second-hand on a watch (jerky) - took it to the dealer and they want $525 for a new cluster that they say is not common - looking on the web, I found this to be a very common problem with Avalanche and the waiting list can be in the hundreds before me - if this is so common, why isn't there a recall and why does the dealer deny the number of occurrences?

The sudden loss of power occurred ten times, but the vehicle was taken to the dealer on six occasions for inspection of the problem. The dealership replaced the throttle body twice, but the problem persists. Updated 2/7/2006 -

The electricity from the automatic control monitor that controls the air conditioning and temperature control on the roof of the truck was causing the consumer to experience severe headaches and she was no longer able to drive the vehicle with the heat or air on. She had to pull the fuse that controlled the monitor because turning it off the wave of electricity was still flowing. The gauss meter that checked the wave of electricity was flashing red when she held it up to her head. It was not suppose to be like that. The symptoms were: Her scalp was real tender and swollen, her left side of shoulder and neck was hurting a lot, and she had to use contacts in her left eye because of vision problems. All of these symptoms were from the automatic control monitor she has never had any of these symptoms prior to this. Since she unplugged the fuse these symptoms disappeared, and she felt better. Her concern was that other people driving this vehicle may never be able to figure out what caused these problems and she felt that this was a severe health risk.
