Hi everyone. I got my GS350 a few months ago at 100k miles and I've put around 15k miles on it, so it is now about 115kmiles. I did a coast-to-coast road trip in it and have driven through extremely cold areas (0-10F) and it has not had a single issue. But last week, after sitting for less about 5 days, the battery dies completely and I had to use the mechanical key to open the vehicle and then recharged it. I looked up my VIN on NHTSA website and it shows no open recalls. Also, this is the first time this happens cuz it's been sitting for a longer period before and started without a problem. Anyone has a clue when does the battery drain issue (caused by a bad ECU gateway specifically) usually occurs? I don't know about the previous owners but it's the first time after 15k miles of my ownership, and I wonder if it is the ECU problem.

It's a 13, and I've checked the tsb, my vin does not fall in that range although it does say "or produced before."

TSB on battery drain. Shoot, I just replaced my original Panasonic battery after 8 years of use. Oddly, the battery was half filled with liquid and not sure if I could have recharged or saved it. Anyone with the TSB link?
