Q: Car dead after leaving lights on.

asked by on

My car won't start after the lights were left on.

Oh no! From the looks of it, it is very likely that the lights being left on drained the battery just enough to prevent the starter from doing its job. In most cases a simple jumpstart of the battery will get your Hyundai Accent going again. However, if your battery is older (between 3-5 years), draining the battery this way ages it much quicker, resulting in a battery that can no longer sustain a charge for a long period of time. This will cause you to develop starting issues in the near future, not very fun at all! You will want to have a certified mechanic come out and inspect your starting system and verify if the battery can be recharged or needs to be replaced. Once this is complete you should be able to get back on the road with no problem, just be sure to turn off those lights when you are done using them.
