I replaced all my lights in my vehicle with LED bulbs and hadn't noticed a problem. Then within the last six months I had a problem with the car. It would shut the engine off but not all of the electronics saying my car was not in park so it could not be turned off. I took it to the dealership and they told me that it was because my car battery was bad and I needed an oil change. The car was barely a year old at that point. It stopped happening for a few months but it did it again last night. So I took the battery off the car so that it would turn off. I reattached the battery today and tried to turn it on but it wont turn over. The battery says it has 12V so I am not sure what the issue could be but when I was putting the battery back on I noticed my DRLs were faintly on. Could they be draining the battery?
