Possible to tamper with 06 Lucerne odometer?

Anyone know how "tamper proof" these things are? I would've thought with the digital readouts that most have now you couldn't really roll them back. Anyone know for sure?

The memory for mileage is usually in the pcm not the digital dash itself., So no.

Anyone know for sure?

Why, are you thinking of buying a car, where you think the odometer is incorrect?

i appreciate the replies. I am looking at one that has VERY low mileage for its age and am just suspicious........

Run a Carfax, no?

Here is something most people don't know....you can go to a dealership and look up the vehicle repair records under warranty......you will get an idea of the mileage from any warranty repairs....
