Q: Q: Car keeps shutting off

asked by on

Lately, I have noticed that my car shuts off when i am driving and sometimes it will die automatically after starting my car. It does not always happen but it is frequent. I have also noticed my lights have been flickering randomly at times. No warning lights have turned on though, could this be my alternator going out? How can I check to be sure.

My car has an automatic transmission.

Hello there, many faults can cause your 1999 Honda Civic to shut off while driving. Noticing the lights going on is a great call as this narrows down possible causes. The most common would be a problem with the alternator, battery cable, battery, wiring harness fault, or voltage regulator. To check the output of the alternator, a load test is performed that tests the output of the alternator while it is running. A qualified technician from YourMechanic will be able to diagnose your car shutting off problem and make any repairs required.
