View Full Version : CTS-V computer problem?

Hi. First time poster. The good news is I picked up my 2010 V about two weeks ago. Awesome compared to my traded in 2008 CTS4 3.6DI. The bad news is about two days ago, every light and message that has anything to do with the brakes (I think) apparently went haywire. Warnings about Stabillitrac inactivated, ABS inoperative, Traction Control inoperative (there are 1 or 2 others but I can't recall them all). Going in to have it checked tomorrow. Anyone experienced this before?

Only time that has happened to me was when the car was being dynoed.

According to the dealer, it's a defective wheel speed sensor causing everything to go haywire.

Sounds right. A failed/disconnected wheel speed sensor will cause all kinds of commotion. Thats why "cbloveday" had that experience while on the dyno. The ABS computer saw the rear wheels moving and not the fronts.

Hopefully when you get it back, "all is good"?

I made the same switch (08 CTS4 3.6DI) to the V last year this time. Different animal aint it?

Enjoy your new car and I hope this is the last of it's troubles!
