What is causing the ABS and traction control lights to come on, and car stops.

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Sounds like your 2011 Jeep Liberty is playing hide-and-seek with the ABS and traction control lights. When the front wheels lock up but the rear ones try to spin, it could point to a faulty wheel speed sensor, a sticking brake caliper, or even a glitch in the ABS module. The fact that it disappears after restarting suggests an electrical gremlin—sort of like when your computer "magically" works after a reboot. Your mechanic might need to run more in-depth diagnostics or test drive it longer to trigger the issue.
