Like many posters, my 2013 Nissan Leaf got this error code all of the sudden: "T/M Vehicle System Malfunction Warning. See dealer." The car would turn on as if I had not pressed down on the brake (wouldn't drive, but radio, etc. worked) and the brake pedal actually felt like it had retreated so that trying to turn the car on felt atypical and was actually not possible. Basically I was stuck in our garage and on the edge of calling to tow it to the dealer.
I took the 12v battery out. Took it to Costco (just like Dave above) and for $82.67 had a new replacement battery in hand (Costco keeps the old one). I installed the new battery and everything is all fixed and working!!! Yippee!
From first reading this forum to a fixed car was about 1.5 hours total (7:00pm - 8:30pm, including driving to and from a Costco in our other car) and $82.67, and I know almost nothing about working on a car, car batteries, or anything else mechanical. If I can do it, so can you.
Based on some other reading, the 12v batteries last about 5 years or so. The new one I purchased says it has a 3 year warranty. The original battery in my 2013 Leaf was going on 7 years old, so it all kinda makes sense in the end.
