Question re my wife's car, a 2009 Hyundai Veracruz (basically a slightly larger santa fe).
So, due to totally excusable circumstances that I won't describe in detail because it was my fault, the key got left in the ignition overnight one click forward so the electronics were on, which completely drained the battery. Completely to the point that all the presets on the radio got reset, and it took 15 minutes hooked up to my car last night to get enough juice to be able to jumpstart it.
On jumpstarting, I noticed that the check engine light had come on.
I drove it around for 20-30 minutes after jumpstarting, check engine light stayed on. I parked it in the garage overnight. Started right up this morning with no problem at all, but the check engine light is still on.
It seems awfully coincidental that it would have come on suddenly right when I jumped it, but I think everything should have been reset when battery died so I don't know why an indicator light would have come on, and stayed on through this morning. I don't like driving around with a check engine light on (especially with 2 young kids and it being winter), but I don't want to pay someone $50 or $100 to run one of those diagnostic tests if I really don't need it.
I'm pretty sure the battery is relatively new, that it was replaced maybe 4-6 months ago.
Thoughts?
