Q: Check engine, battery, and oil light comes on and car stops.

asked by on June 27, 2017

I was driving home from work one day and when I pulled up to a stop sign my check engine, battery, and oil light came on. Nothing happened when I tried the gas pedal. I turned my car off and turned it back on with no problems and it ran fine. A few weeks later the same thing happened and its been happeneing more often. If I'm not fully stopped when it happens the car continues to slow down even if I press the gas and the rpm meter stays at 0. I checked the oil level and had the battery checked at AutoZone and both were good.

My car has 30000 miles.
My car has an automatic transmission.

It sounds like you are having an intermittent charging system failure. I would recommend having the output of the alternator tested with a digital multimeter. You will want the alternators output to be around 14 volts or maybe just a little higher. Anything below 14 volts is a suspected faulty alternator. If the alternator is not charging the battery properly, this would explain the battery light and check engine light as many vehicles will set a check engine light in the event of a charging system failure. The oil light may be related as well but it would be difficult to tell without replacing the alternator first. Consider YourMechanic as a certified professional can come to your home or office to test the alternator for you.
