While driving or in park the tachometer sticks as does the speedometer. This has lasted from minutes to days. The vehicle appears to run properly, however, I am very leery of my safety and the safety of my children when they are in control of the vehicle.

My husband, 3 year old, any myself were driving back from a doctor appointment when we had to make a sudden stop because of a driver 2 cars ahead of us that quickly applied brakes to make a quick right hand turn. The driver in front of us in turn had to apply his breaks on and when my husband applied the brakes on our 2004 Chevrolet Avalanche there were no brakes!! Our 3 year old was asleep in the backseat!! We hit him of course because we could not stop (going downhill on a busy highway) we ended up having to coast up the hill in the middle of the lane because there was nowhere safe for us to pull off . There were almost several other accidents due to it being a blind spot for drivers coming over the hill both ways and we were stuck there because we had no way to stop ourselves again. …
Transmission & drivetrain
(1) 2005 Chevrolet Avalanche 1500. 119,000 miles, 95% interstate. Vehicle does not tow, go off road, or engage in other activities which would increase the stress on the drive train beyond normal wear and tear. Transmission has received regular maintenance per the manufacturers recommendations. (2) part failed during merge onto highway from complete stop. Failure resulted in a power loss to vehicle, making acceleration very difficult and maximizing vehicle speed at 35 MPH. Traffic behind vehicle had to significantly slow down to avoid accident. (3) dealer replaced torque converter and immediately shipped part off site before request for returned part. Dealer claims customer abuse.
May 2006 electronic switch replaced because 4 wheel drive was engaging without being activated. Had been to dealership several times with problem and finally had them admit there was a problem. Feb 2008 front wheel drive had to be replaced as it was a possibility that it could lock up while driving. Out of warranty so I had to pay $1,300.00 in repairs. Contacted GM exec offices and they investigated only to advise they could do nothing because the car warranty 35,000 miles had expired and car had 65,000 miles on it. I think the front end drive was damaged when the switch failed and it took time for it to fail.
