This problem was a pain in the butt. The sensors failed, and braking became totally erratic below 10 mph. The fact that both the sensor and wheel bearing had to be replaced baffles me. I am not sure I was not taken by the dealer on this issue.
When traveling at low speeds, the ABS will engage. Our mechanic put in a new ABS sensor, however that did not fix the problem. We are still troubleshooting the issue. Sounds like there are lots of problems with various Chevy models around this time.
