My son reported the errors in the title of this post to me yesterday. I took it out for a drive and the errors cleared themselves after driving for about 2 minutes. This morning I'm going down the hill of my court and touch the brakes - nothing (as in no braking - felt like someone greased my brakes) - 'Low Traction' message appears and brakes engage after about 20 ft of roll then all the error messages returned with the ABS light again. I drove the rest of the way (28km) to work without incident but the messages didn't clear themselves this time. Had a car been stopped ahead of me at the end of my court this morning I would have slammed into the back of it. I had a shop fix an air leak in my driver front wheel last week so they would have removed / reinstalled the wheel. Any advice on where I should look? I'm handy mechanically...or is there a recall / TSB that would address this?

Thanks.

Not enough info to know what the problem is here, and it's clear that that the regen cut out before the traction lights came on, so it's probably NOT something simple enough to shade-tree. It MIGHT be safe to drive to a dealer (once the lights are on, you've got friction braking only and that's appearing to work), but frankly any unknown problem with the braking system (on any car, not just the Volt) is grounds for getting it towed in.

All of those systems use the wheel sensors. I'd strongly suspect a wheel sensor is offline. And, given the wheel service just performed I'd begin my inspection with that hub.
