Past two weeks I had an intermittent ABS/SVS lights come on and off. Now it turns on after few minutes of driving but before it does, I feel ABS engaging at low speeds. Kinda annoying but once it trips the ABS light, it acts normal. Both front hubs are less than 2 years old. any ideas? Didn't have time to take a closer look yet but jacked it up and checked both wheels for play, all good. Speed sensor or wiring going bad?
