It could, yes.

 

[Brandonh36898]

Well I just ordered the motor mounts..I'm going to do them myself to save $450 witch is what I was quoted to change them!!.. I hope it fixes it..

Yes it can and clear all of the codes before deciding if the mount wasn’t the problem and check all connections at each corner for loose sensors.

In regards to your intermittent cruise issue, the Service stabilitrac most likely is not the cause of your issue. My ‘08 XL Denali was having regular stabilitrac earnings due to a bad steering wheel angle sensor and cruise control was never impacted. I would consider going with an AC Delco brake switch. A friend put a Dorman brake switch on his Tahoe and it didn’t fix the intermittent cruise issue so he took it into the shop to fix it and they simply put an AC Delco brake switch in and problem went away.

Yeah..on the scanner yesterday we got a cruise control code.. although that was not my main concern at the time..just got so many little bugs to work out.. replace wheel speed sensor today. Motor mounts will be here Friday... Going to change transmission fluid today... hopefully I can get all this crap worked out... Thanks for all Yalls imput..

Well when you get this all sorted out you can go racing with us! We've met twice at Palm Beach International Raceway and will probably meet up next time at Orlando Speedway so other guys can join us. Waiting for the weather to cool and for Randy to quit blowing up his Denali.

You're about an hour and a half from me.

 

[Brandonh36898]

Lol I got some friends down in Palm Beach...so that would be cool.. although won't be doing any racing.. LMAO

I’d recommend searching the P0300 and Stabilitrak issue on here. Sounds VERY similar to this issue.

For my ‘07 it was bad coils that caused my issue at 130k (finally identified after testing the fuel pump, searching vacuum leaks, cleaning the MAF, replacing the plugs, wires, air filter, to resolve)

For me it had nothing to do with the suspension, speed sensors or motor mounts - though it felt like that at first.

Good luck!!
