No, not yet. Probably will have my dealer do it next spring, before the powertrain warranty expires. Hopefully those TSB modifications, in conjunction with the Range V8 module, will finally end the oil usage problem. I just wish the General would've come clean about the AFM problems earlier and done a recall instead of a TSB just because they want to keep it on the down-low. There's gotta be a few million GM trucks/cars/SUVs out there with this problem, but no doubt the General does not want to derail its comeback program.
