For the last 2 years I have been dealing with a parasitic draw on my Murano 2007. I have replaced 3 Alternators, 3 batteries. Last year I made the mistake of having a new stereo (with GPS) and a remote car starter installed. Last Winter Auto Shop had car for 3 weeks and found broken and chewed wires and fixed and replaced all the found. I thought problem was solved. Had no problems for about 3 months, then once again dead battery in the morning. Had trickle charger installed on car to cover my A—, through the Winter months, however woke up to dead battery and Trickle charger reading “Error and Reverse Polarity”, car is back at Auto Shop, they have had it for 3 weeks and haven’t been able to find the draw. They tell me it isn’t the new stereo or remote starter. They haven’t been able to pin point anything.Does anyone have any suggestions.
