What does it cost to fix the Stabilitrak?
Lets see, you did not post what vehicle this is or why you are asking . Your location is unknown so I guess you will have to get an estimate from a shop . If this vehicle has less than 36000 miles and less then 3 years old it should still be under warranty.
I’m in Grenada. Mississippi vand it’s a 2008 Trailblazer
The stabilitrak warning could be on for almost any number of reasons
You need to get the codes read out and post them here
Heads up . . . many/most cheapo code readers will NOT read abs codes
It could also be because one of your tires is under inflated, also triggering a TPMS light.
