All warning sensors went off on the dash, my brakes locked, luckily at low speeds either while parked or pulling into a parking spot. It had to be towed 3 times, one time we had a little smoke coming from under the hood which turned out being the corroded harness. My brake lights were all stuck on. Jeep says it was the wheel speed sensor, 2 out of 4 have been replaced. I've also had to have my wiring harness replaced twice (within 6 months) due to corrosion. All of this happened at the same time.
