Dead Murano

5000k miles is 5,000,000 miles. I'll bet it is just tired.

Of course. I didn't catch that.

I am waiting on a tow now for the same issue; battery drain on a 2017 that I had less than a year. This is the second time in two months.

My 2011 murano goes dead often. I'm going to bury it since I'm afraid to go anywhere in it. It only has 43,000 miles. Dealerships can't figure it out and diagnostics businesses can't figure it out. So, Mr. Manufacturer what is going on with this car !!!!!!

Have a 2013 doing the same darn thing.Just quit at a car wash.Third time this month?Whats the deal/

( 2014 Murano convertible ) “Dead battery” Not sure if this will help anyone. Replaced battery after testing cca was low. Vehicle came back roughly six days later, Replace battery, retest for maximum draw amperage. Passed! Vehicle came back seven days later. Again only able to bring back batters cca to 25% drop of cca after charging batter. This was the third new battery put in this Murano. In my opinion it’s the gate module a.k.a. radio/navigation System internal shut down memory is corrupted. The unit continues to draw small amount of amperage continuously. System is on borderline speck of continuous draw. Until two hours after complete shut down, it does not drop down to minimum draw specifications. Updated navigation gateway software on this 2014 Murano convertible, drains brand new battery within a two week timeframe. Made no difference. Replaced full head unit /Gateway/ Radio navigation System. Vehicle has been driving for three months now with no issues.

We've been having unexplained battery failures in our 2011 Murano for years. It seems to need a new battery every 3 years, and nobody can tell us why. We recently put a voltage data logger on the battery to see if we could get some insights. It was set to record the voltage every 20 minutes. Within 3.5 months, it recorded 3 dead battery events, down to like 5-8 volts. I expected to find evidence that the lights were left on or that it had been left in accessory mode because the pushbutton start can be confusing. I did not find any obvious voltage decline immediately preceding the dead battery events. The dead battery events did not coincide with letting the car sit unused for several days or after making multiple, short trips. I wish I had set it to record the voltage every 20 seconds for an even better understanding of what preceded the dead battery. We just replaced the battery again with an absorbed glass mat (AGM) battery with hopes it will be more tolerant of whatever is happening. I have not yet measured the current draw under various conditions. One guess I have is that Nissan's computerized charging routine is simply too conservative for the type of 'round town driving it usually sees. The voltage on the last 3 yo battery would typically charge up to about 12.40 volts and decay to about 12.20 volts within a day or two. It was about 12.25 volts immediately preceding the dead battery events each time. This is still an annoying mystery.

I should add that each time the battery was dead, jumpstarting got it going again. Thus, this does not seem to be a problem with the anti-theft system.

By chance, do any of you having this battery drain issue have a sunroof on your Murano? I recently helped a neighbor with her 2005 Murano, she had two new batteries installed and still having the same dead battery after parking it and a few days later, the battery is dead and doesn't start. I may have stumbled on the cause but would need some of your feedback to confirm.
