Looking for some help with my 2010 Tahoe LT 5.3 I apologize in advance for the long post, trying to provide all the info.
About a 2 weeks ago, I drove my Tahoe for about 20 mins and parked it for about 6-7 hrs. I went to start it and everything was dead. No interior lights, no power locks, etc and obviously no crank and no start. Thinking dead battery, I got a jump pack and it started right away.
Drove home no problems. I went to go start the car later that night(3 hrs later) and again no power door locks, no interior lights, etc and no crank and no start. No lights were left on both times so thought probably a weak battery(4 yr old battery) and didn't look more into it. The car sat overnight, and in the morning I went to go check it out some more, and to my surprise, everything worked(lights, power door locks) and the car started right up. So now I am at a loss of how a car that had no power 2x in the same day, miraculously gets power overnight and starts right up.
I checked the battery cable connections at the battery and they were clean and tight. Tested the battery was at 12.25-12.5 V. Had no problems since this occurrence. Only other electrical issue was back in December. I was driving, at night, at a low speed and coming to a stop sign. As I came to a stop, I went to go put my high beams on and all the dash lights and head lights went out for about 5-8 seconds and then came back on. However, I cannot remember now if the car shutoff, but if it did, it started right up. That was the only time it has done that.
Recently replaced the fuel pump(New OEM) about 6-7 months ago and replaced the alternator (New OEM). Replaced the alternator because I was getting the service battery charging system message at the time. Tested alternator and was not working properly. Replaced it and message has not come back. I am not getting any codes or messages.
I'm thinkin possible bad grounds/battery cables? I live in the Northeast and they love salt here. Want to see if anyone had similar issues, as now I'm afraid of getting stranded somewhere with this car.
Thanks for any help
