Hi Folks,
After seeing this recall, 46.9K Leafs 2013-2016 and having my brakes drop out in the cold (apparently regen appears to shut off when cold intermittently), I took it to the wheeler-dealer: https://www.csmonitor.com/Business/In-Gear/2016/0318/2013-2015-Nissan-Leaf-r ecalled-for-braking-problem-46-000-vehicles-affected#:~:text=Nissan%20is%20r ecalling%20more%20than,braking%20ability%20in%20cold%20weather. <https://www.csmonitor.com/Business/In-Gear/2016/0318/2013-2015-Nissan-Leaf- recalled-for-braking-problem-46-000-vehicles-affected#:~:text=Nissan%20is%20 recalling%20more%20than,braking%20ability%20in%20cold%20weather.&text=A%20Ni ssan%20Leaf%20electric%20car,(January%2012%2C%202016> &text=A%20Nissan%20Leaf%20electric%20car,(January%2012%2C%202016 ). I was asked to report on the actual response (below) The Roanoke VA Southern team Nissan dealer told me that the warranty expired and had to charge me $250 for an hour of labor (I must be in the wrong business) to read the software through the OBD-2 port and see if it had the brake update. I was told it had the latest update although I hadn't brought it in before. (In 2015 it was in for an air conditioner failure under warranty.) I was then told that the *12V Aux* battery is what was causing the cold brake drop out *after* I printed out a photo of the red exclamation point and temperature display at 25F *and* the recall notice, showed to them. (I guess they thought they would sell me a pricey battery). I drove it to Advance Auto and bought a new fancy Optima Yellow Top $330 battery to replace the 2019 (Advance Auto battery I replaced still under warranty). Since the present battery was still under warranty, they tested it and said it was OK but gave me $189 store credit. Dealer service dept response: iPhone Message 3/8/22: "Hi This is Southern Team, we are calling because we are looking over your vehicle. Unfortunately what we are saying is you *do* have the latest and greatest software installed to your vehicle regarding the brakes and what we are noticing however is that your regular 12V battery is registering 300 CCA to 397CCA and should be closer to 500CCA. You also have a bunch of low-voltage codes stored in the system from where we have obviously plugged it in to perform a software update and see what software version was installed last. We think that the battery is what's causing the light on the dash and resistance with your brakes - is actually related to where your system doesn't have the appropriate amount of electrical current running through it so they're recommending that you actually replace your battery." The printout after service reads in caps: "A CUSTOMER IS REQUESTING NEW BRAKING SOFTWARE TO BE UPLOADED. CUSTOMER BELIEVES THIS WILL CORRECT THE CONCERN OF THE TRIANGLE LIGHT POPULATING AT TIMES WHEN BRAKING, FEELS LIKE BRAKE BOOSTER ISN'T WORKING, ESPECIALLY WHEN BELOW FREEZING. TAKES A LOT OF EFFORT TO BRAKE --- UPLOAD SOFTWARE ONLY - 1.0 NBE INSPECTED VEHICLE AND FOUND LATEST SOFTWARE FOR BRAKE SYSTEM ALREADY INSTALLED - LOW VOLT CODES STORED - REC REPLC 12V, 381 CPN $250 41859 1.00 CUSTOMER REQUEST WE PERFORM A SOFTWARE UPDATE TO THE BRAKING SYSTEM FOUND ONLINE WHERE IT WOULD FIX THEIR CONCERN. CHECK BRAKE PART NUMBER AND ADVISE CUSTOMER THERE IS NO UPDATE AVAILABLE FOR THE BRAKING SYSTEM - IT HAS ALREADY BEEN REPROGRAMMED ELSEWHERE. DID FIND MULTIPLE LOW VOLTAGE CODES STORED DUE TO WEAK 12V BATTERY. THIS CAN CAUSE THE SAME CONCERNS YOU HAVE - RECOMMEND BATTERY REPLACEMENT." Question: has anyone heard of with this recall with the 12V battery causing the braking regen to drop out on cold weather - or is this *junk science* ? Have a renewable energy day, Mark Mark E.
