2004 impala speedometer problems

2004 Impala speedometer problem:
Mine has 44K mi. Last week ,a mile out of my driveway and going about 20mph, my speedo was reading out maximum (over 120mph). Breaking didn't help, when I turned off the car I noticed it dropped about 10mph, so I turned the car on and off about 10 times to get it to read 0mph.
About two hours later I drove it to the dealer, and the speedometer worked OK. They said I needed a new instrument cluster, which they had to order. It was over a weekend, and in the meantime my speedometer had no issues. About $450 and a hour at the dealer a second time, I have the new part. Thought I'd share.

Oh and I found this on Wikipedia:

note that 2004 Impala (or any Impala) is on the list at this time.

jallen8,
Did you keep your old cluster?

[jallen8]

sorry in my above post that i left out the "not".
Impala is NOT on the list.

I didn't get my old cluster, it was not offered to me by the dealer (plus I don't know what I would have done with it). i do recall seeing "exchange" on the work receipt, so i assume that i got some credit to exchange it for the new part ($255).

The clusters are refurbished and the mileage reset to "0". The Chevy dealer I took mine to had to have the cluster reprogrammed with the correct mileage.

I now have 124K on the clock and it was done at 82K. About 500.00 to replace.

The bearing in the stepper motor for the speedo display go bad. I had the original same problem as the first poster stated. I am running this car until the wheels fall off.
