Brake and battery light flashing while driving and the car jerks why does it do that

Hello, if your battery light is on or flashing, focus on vehicle electrical power before diagnosing any other warning light or concern. Check the battery first, ensure it is good, fully charged, and able to sustain a load. Next you'll need to check your vehicle's charging system. If the alternator and voltage regulator is not providing sufficient output to recharge the battery and run the vehicle, then lights will flicker, warning lights will come on. Pretty confident you'll find some things to go on. www.repairpal.com/repair-shops
