Hello forum, I bought my 2009 Z71 LT Avalanche last June and haven't had any problems since. Recently I have been getting codes "Service Stabilitrac..Service Traction control..Stabilitrac off...Traction control off.." and ABS light on. It was doing it intermittently and would sometimes come on during start up, sometimes when driving. It would always go away for a couple days then come back randomly. It stays on now so I took it for a code readout at and auto place. Code read was "REAR LEFT SPEED SENSOR CIRCUIT", now, Iv'e heard of people with the same dash lights on with loss of power also. They said they called *ONSTAR* and that was the problem? This is not happening in my truck, I do not have "LOSS OF POWER". I called ONSTAR they told me they could do nothing. The only 4 wheeling I've done is driving on sand at the beach maybe 5 times last summer. I actually just drove it on the beach last week with the dash warning lights on and there was no problem.
Has anyone else had this problem? I'm just wondering if it really is the SPEED SENSOR or some other underlying problem. Just asking before I buy a new sensor circuit and install it.
Thanks for the help! BTW, only 81k miles.
