Default Check Engine Light

Check engine light came up with VSC and PCS warning lights and the exclaimation mark!
Brake Hold didn't work either.
Display said get it checked by dealer.

Dealer diagnosed faulty oxygen sensors (x2) and ordered the parts.

Has anyone else experienced a similar problem?

No, I haven't had any problems like that.

I've had the check engine light problem too. If the code was P0456 the fix is to have the dealer replace the neck that the gas cap screws into. Sometimes the threads on the neck allow a tiny air leak which triggers the code and disables the Hold Button, Cruise Control, etc.

If your code is P0456, it's probably NOT the O2 sensor or your gas cap or the charcoal canister.

Good Luck
