I have run through in my head the past few days leading up to the no start and wanted to provide additional details in case they are related.
On Saturday, I pulled the 200 away from the garage so I could paint a few items in the garage. We have noticed a bit of a musty smell and I decided to dig into that and see if any of my connectors had corrosion. The lowest connector on the passenger side footwell had a small amount of corrosion so there has been moisture there. Everywhere else was clean. We have a few of the indicators there might be issues such as flickering tail light and twitching side mirrors, both sides. Pulled it apart and cleaned it up as best I could including spraying CRC electrical cleaner in there. Also put a dab of CRC dielectric grease in each pin area that had any corrosion and put it back together. Didn't solve any of the twitching or flickering but the car started and I pulled it back in front of the garage. I played with the TPMS Carista app a bit that night as well as looked through the programmable bits in Carista. Only changed one setting which was whether or not to turn on A/C when you hit Auto on the hvac system.
On Sunday, my wife drove it to church and back without issue. That night, I had noticed in all my reading that you are supposed to be able to open and close the windows with the remote. I went out and pressed the unlock button and held it, and sure enough, all the windows and the sunroof opened. However, when I pressed the lock button and held it, multiple times, they would not close. I went out to the vehicle and hit the start button twice and closed all the windows. Thought it odd you couldn't close all the windows with the remote. This is when I thought I might have left the ignition on and drained the battery. But now thinking about it more, that isn't possible because I didn't leave the remote in the car so walking away would have turned off the ignition.
Monday we didn't do anything with the car. Just sat in the driveway.
Tuesday, yesterday, my wife went out to drive the car and there was nothing. No lights, no dash lights, no clicking, nothing. When I got home from work, I immediately figured I had left it in ignition mode, as mentioned above, and threw a charger on it. Charger registered 12.0 and 0% charged. I left it on, charging at 30 amps for about 45 minutes and went out and check it. It now said 82%, which is really fast charging but it didn't register at that time. This is when the fun began with the no start as detailed in my original post.
This morning I went back into the Carista app to make sure there wasn't anything I had done that might impact the starting. I didn't find anything. Battery was getting low from all the attempts and starting so I threw the charger on and this time noticed the negative cable was loose on the battery. Tightened it up and tried to start it, but no go. Took both cables off and put the charger on to slow charged today while I am at work. Battery is a Toyota batter from 11/22.
Again, not sure if any of the details are related to the no start but wanted to throw it all out there just in case. One thing I am guessing is that the appearance of the dead battery was more likely the slightly loose negative battery cable and my putting the charger on it probably moved it enough to get a connection.
Again, any help or ideas are welcome. Eventually I will have to throw it on my trailer and take it to the same dealer that told me that my TPMS sensors for my alloys won't work in my steel wheels because the steel wheels cause interference to the signal since they are steel. Not excited about that prospect as they have little experience with LC's here in Billings MT.
