Low battery message --- solved?
As one of the contributors to this thread a couple of years ago, I wanted to give an update with some good news.
Background: since my previous post, I continued to get the low battery message, especially when the sound system was still running after the engine had been shut down. Late last fall, I got a new message on one occasion: "Low battery, power save mode." The problem continued through the winter, but was no worse than in other seasons. At no time was the engine slow to crank or start.
Last month, I took it in to the dealer for a scheduled service, and I asked them to check out the battery and electrical system. Both were normal. They suggested a software update that might help. The update targeted the ECU, the transmission and some other stuff I can't recall. I had them do the update, and in the three weeks since then, the low battery message has not recurred. Keeping fingers crossed.
If anyone is interested, I can try to find out the version/number of the update.
