At the very least, if you trust the place that did brake work last fall, take it back there again.
They will know what’s going on now.
Thanks, Responsibility. I checked and it was the right front and left front sensors that were replaced. Mileage then was 49,686. Now is 50,686 (oddly enough). Going to try to reach them now because I don’t know if it’s safe to drive it the 20 miles to them.
