My daytime running lights randomly stay on and drain the battery?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! When your daytime running lights decide to stay on like a stubborn houseguest, it's usually an electrical control issue. Since your 2008 Jeep Grand Cherokee has LED headlights, it could be the body control module (BCM) acting up or a faulty relay sticking in the "on" position. The BCM controls a lot of the vehicle's electronic features, and a glitch there can keep the lights on even after the engine is off. You might also want to check if any aftermarket wiring from the LED conversion is causing mischief. If you need any further advice or want help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554!
