Catastrophic Failure

Mon Aug 05, 2019 5:14 am

2 weeks ago I went out to go to work and noticed the fail light on the charge cable was illuminated. I unplugged it and checked to find the battery state of charge was @ 47% and there was a big red warning in the dash display.
I called Nissan Roadside Assistance and had the car taken to my selling dealer up the street.
It turns out that the control and inverter modules had literally melted. They were replace under warranty by Nissan. Next the 300 amp fuse in the sealed battery box was found to be blown. They had to drop the battery to renew it and then seal it back up. Now they are getting codes for something on the battery positive terminal that will require replacement of the battery.
Anyone else hear of this happening?

Sounds like a short circuit. I read similar stories after people jump started EVs with cables swapped. If that is not you, then ... perhaps rodents ?

All that and the car didn't catch on fire?
I am very impressed.

No rodents or any other external cause suspected. They checked those things first to determine if the financial responsibility would fall on Nissan or my home/auto insurance. They are covering it all under warranty.
The charge cable is ok and the 50 amp circuit breaker in the house wasn't tripped. My wife is in insurance so she checked the lightning strike map and there was no lightning that night.
I'm very glad it didn't do a Ford by catching fire and burning my house down. Not sure if I want to keep it in the garage anymore though...

Out of curiosity, what year and mileage is your vehicle?

I actually had been thinking of putting a smoke alarm in my garage anyway. I doubt the EV rate of fires is really higher than ICE but either way, it wouldn't hurt. I just wasn't sure if I would hear it from inside, but that's easy to test. They are only $30 bucks, so its not like its a huge cost. The fire extinguisher in my garage cost more.

That's what a warranty is for I suppose. Brand new vehicles have major failures now and then. My parents brand new Nissan Titan had to get towed to a dealer because something broke with just a couple thousand miles on it.

It's a 2018 (manufactured in March, 2018) with18,000 miles. Bought it new in late August, 2018.
I put 54 miles of highway driving on it each way to work (108 miles total) 5 days a week and charge it nightly. Plus some weekend driving. I live in SC so it's usually in the 90-100 degree range in the summer.

6-8 weeks to get the new battery in; on top of the 3 1/2 weeks they've had my car already. I guess the bright side is that I'll have a new battery at 18,000 miles. I asked them to switch out my Nissan rental for one that has ProPilot. This having to actually drive a car sucks...

That is an upside.

Did Nissan make any updates to the cell chemistry in 2019 on the 40 kWh battery?

Between the inverter and the battery, that is most of the drivetrain. I guess you will find out if the motor is fried once the other parts are replaced. I have to admit, I would be clamoring for a new car.
