My start stopEngine light came on yesterday and today my car won’t start

Hello, check the engine's 12 volt battery state of charge and the ability to sustain a load - this is the basic step you must do before guessing anywhere else! If the battery is good, then check for any diagnostic trouble codes that may have been set in the engine's processor. Those codes - if present - can give clues on where to start testing. Hands on testing is needed to see what is happening. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
