2003 Avalanche. We recently had a blizzard around here. So I know the undercarriage has been dragging through a lot of snow. Speedometer works properly when the truck is cold. After driving for a bit, it drops down. Says I am going 20 mph when I am really going at least 45. When I stop, it drops below zero instead of the needle pointing right at 0. If I shut it off and let it sit for a minute, when I restart it it works again until it warms up. Have I got some kind of moisture condition caused by the snow?

 

I too had the exact same thing happen to my 03 Avalanche-and it has nothing to do with blizzards(we don't have them). My boyfriend said 03 Tahoes have a recall for that-and I'm hoping Avalanche does too-so they will reimburse(it's not cheap to fix).

 

There is a recall on ipc 03-04 7 year 110000km they replace the ipc call your local dealer

 

I have heard that dealers will do the recall regardless of the mileage, due
to safety issues.

Good Luck
