After replacing my door handle last week on my 2015, I got a I-Key System Error. I have had no issues with the car since new. It has 14700 miles on it. They told me warranty is over because it’s from the date of being built. (Crap warranty) This is my second leaf and I love them as a second vehicle. So I went and got the OBD2 and downloaded LeafSpy and I’ll admit it’s a cool ap, what does all that mean? I downloaded the DTC’s and OMG! 23 of them. Yes I unplugged battery a total of two times in a two week period. Still the same. I bought the obd to clear out the DTC’s but then I read more and It’s not recommended. I had my 12v battery replaced about 10months ago and let me tell you, you will know when it’s bad. The whole car freaks out. I did test my 12 volt battery and it’s at 12.8 volts. I hooked charger on it walked away checked on it and charger said full. Not sure if it topped it off or if anything at all. So any advise would be great.
Thanks!
