Does anyone know if Nissan warrants the original battery under the 3yr/36,000 mile warranty? My rig had a weak crank when I turned the key and almost didn't start. Both trip odo A & B reset to zero when it did fire up. My head unit retained all the XM presets though. I've got a 2015 CC DR with little over 25k on the odo. I purchased it June 2015.
