: "Traction Engaged" kicks in without warning

I am puzzling my service manager with a problem that my '04 SRX has developed.

Out of the blue, while driving, there is a buzzing sound from the transmission, a loss of engine power, and the "Traction Engaged" screen display on the center LCD.

It doesn't have anything to do with turning, or driving on snow or ice, or rainy roads. You can just be driving along, and it will happen. It does this about three or four times a day. It is quite distressing when it occurs when you need power (like entering a highway).

My dealer kept the car for two days last week, said that he ran "all tests" and that the car checked out fine. He reset the car's computers, and test drove it, but the problem recurred after this. It is back in for service this week. I think it is more than an annoyance. This car is unsafe to drive like this.

Has anyone had this happen, or know about any TSB that I can "inform" my dealer about?

Thanks.

I had a similar problem -- it turned out to be a wheel speed sensor that was intermittently going bad. Apparently it would randomly "report" the wrong speed for my left rear wheel and the traction control would react accordingly.

I second this. The dealer should have the common sense to look at the wheel speed sensors. If it's an intermittent problem, 'running all the tests' might not catch it. Unfortunately the sensors are part of the hub assembly so it's not easy to swap them out to see which one is bad - you have to replace the entire hub/bearing assembly. They probably don't want to do this (it's under warranty I presume?) so they're playing 'stumped' with you.

I've had somewhat of a similar issue. For me it went off when I made a u-turn. It did go off once when I made a left into a parking stall. I've had my car for a year and it has only done it about four times total. I could never repeat it at the dealer and it has been months since it happened.

When you brought it into your dealer, did they pull any error codes?

No error codes reported.

"We couldn't find anything wrong with it." :tisk:

Not completely off topic: We spent a couple thousand bucks and more than a couple nights in a hotel fighting a pesky 95 Suburban that would act up, eventually leave you with just 2nd and reverse, etc... you could feel somethin' goin' on in the braking... computers changed, on and on... finally called another dealer and he told us to have service check the wiring connector on a specific wheel. Voila. Fought GM hard for some relief on it but it was like screaming at a brick wall... All that to say this thread is probably on the right track.

I had the exact same problem with my 04 CTS. It only happened twice in the 6 months I owned it though, not every day. Both times, I was on dry pavement, going slowly, both times I was in parking lots. I had to stop the car and shut off the engine for a few minutes to get it to behave normally again.
