So I got my car aligned and a FULL set of new tires, and when driving back from the shop, I noticed its stuck at 40... No matter how fast I go, It stays at 40..Any ideas how to fix?

try this:

1. push/hold the trip button.
2. turn the lighting switch on.
3. turn the ignition switch on.
4. (within 5 seconds) turn the lighting switch OFF, then ON, and OFF again.
5. (within 5 seconds) release the trip button
6. push and release the button 4 times repeatedly.

this starts the gauge cluster self diagnostics...

the beeper will sound
the lights will flash
the LCD will flash
the needles will sweep

if they/one does not sweep properly, replace the cluster.

to exit diagnostics, turn off the ignition.

Have you ever opened your cluster for any reason?
