Esc light coming on causing car to turn off what may it be?

The ESC light -- which stands for Electronic Stability Control -- is typically measuring function of vehicle speed at each wheel or overall, as well as stability control dynamics. I'm not sure what could be causing the vehicle to stall that is directly related to this light coming on, but certainly a malfunction is occurring, and diagnostic testing can certainly start in areas where faults are detected, such as the ESC system. A good diagnostic tool capable of reading chassis codes is essential for this. I would also have a look at the battery and ensure the state of charge is full, as well as ensuring it can handle a load. Then, check the charging system to ensure the alternator has sufficient amperage and voltage output. For assistance, contact a shop near you: www.repairpal.com/repair-shops
