Jeep Recalls 2,564 Wrangler 4xes for Potentially Faulty Battery Packs Documents say that the pack "was built with incorrect fasteners to secure the 200-amp fuse, which can generate excessive heat."
Bad experience with a Tata Tiago EV due to faulty battery
2. Now that the battery is replaced, he is finding it very easy to bring down the wh/km. It was not the case so earlier. We are assuming it to be the issue with the earlier battery pack. Anyway, your point is well taken and for the next purchase, we will make sure to not trust the sales people (just a joke!)
5 Common Problems With Batteries In Electric Cars (Explained)
1. Faulty or Damaged Separator. Chevrolet, one of the biggest brands in the auto industry, has had to recall some of its Chevy Bolt models. This was due to a faulty electric car battery separator, which rendered the models unsafe. The main purpose of the separator in a battery is to separate the anode and cathode without affecting the ions.
