No Crank No Start (1 Viewer)

Hi All,

I'm trying to diagnose what is going on with my 2005 LC. I had a new battery installed in May 2021. And it was working fine until this past week. I found that I was unable to start the LC at all. I had to use the key to open the door and when I turned the key, there was no reaction at all. Not even a click that I read that some folks had when they had a no start issue.

I managed to use my NOCO jump starter to start it with the Manual Mode button. Once it started, I had no problems driving. The next day, I tried to use my multimeter to test the voltage in the battery. It was reading a low 2.3 volts. How should I go about diagnosing, what thing is causing the issue? For now, I'm planning to go to Costco to get a replacement battery since I still have the warranty. But I think there must be some other issue going on.

Could it be a parasitic drain from somewhere, and over time it destroyed the battery?

I'm based in Chicago. I wouldn't mind going to a mechanic to check it out. But I'm new to the area and I don't know who to go to for this type of issue.

If the battery is in good condition, then check for corrosion and battery cable connections. Check the alternator if the cable connections are good.

Thank you. When checking the battery cable connections, is just a visual check of the wires?

Don't overthink it. Batteries sometimes fail early.

Just get a new battery in there ASAP and keep an eye on it.

Yes if you have the skill. I can't tell if the connection is good by looking at it.
