Driving with one Bad Module?

You could keep driving with that battery for a few days to a few weeks. I do not recommend you do so.

Your car will continue to lose acceleration to the point of becoming a traffic hazard.

It's time to start looking for a battery solution.

 

There's no definitive answer; it could go on the next trip and put the car in emergency "turtle mode". One thing is for sure, it's coming.

Pretty much everything in this quote is bad for the HV battery; low use, letting it sit, hot climate. BTDT

Assuming that car with such low miles is in great shape otherwise, a new battery is the best solution if you want to keep the car for years and will also add to the resale value. For such a short commute, a plug-in is an even better solution. BTDT too.

GOOD LUCK!

 

After about 1-2 months the bad modules blow up and the car suddenly shuts down.

 

I say if you can DIY replace the bad module yourself with one from amazon or ebay. I had similar issue as you and went this route and my car has been running 1500 miles without problems with the bad module replaced. If you do this make sure you balance and load test the module before installing back. Note this is only a bandaid fix but atleast it will get your car working as normal again. I'm hoping mine will last atleast 10k miles(cross fingers).

Do they really?

Photographic evidence and description from personal experience please. I'm curious to see where the failure tends to be and under what conditions. No photos off the internet, seen some of those..

 

Here's some of my first hand experiences with this problem. The first two images coincide, codes with the battery, this car would not go into ready mode. Sometimes the car continues to function and if you look at the live data the voltage on the affected block jumps like crazy from 12v under load to 20v when charging almost instantly.

 

I think battery photo 4 wins the prize. Have you seen any Gen 3 modules fail in a similar way?

 

You may have a day, you may have a few weeks.
I had a customer that thought they could make it 3 miles to my shop. Nope. Engine started revving super fast, no power, got stuck in rush hour traffic. Finally made it home. Scared and shaken, but safe.
Replaced the HV battery the next day.

 

None. Gen 3 is a lot better at battery management than Gen 1 and 2. Most failures of Gen 3 batteries that I have seen have been due to heat, the center of the battery degrades faster than the outside creating an imbalance due to different resistance and capacity of the inner battery modules, the rest have been due to typical cell failure found in Gen 2s.

 

Excellent photographic evidence.
