[5280tahoe]

It seems like every time i shut my 01 tahoe LS off it loses 2 ticks on the gas meter .

Also Service engine soon ? does that mean oil change ?

#3 My ABS light and Brake light are on at the same time and never turn off . Do i need new brakes or what .

New to having a tahoe , used to have Escalade . Please help

If you need an oil change, the DIC will tell you change oil soon. I think ABS and brake light usually indicate bad wheel speed sensors or abs sensor. I could be mistaken though. For the SES light, I'd see if it's throwing any codes.
