Yesterday, a message appeared on the Chevrolet website about the causes of ignition of the electric “Bolts”. At the same time, the manufacturer told how they will eliminate the defect and what they will do in order to prevent this from happening in the future.
Let’s start with the main thing – the LG batteries are to blame, however, in order for a fire to occur, it was necessary to make two extremely rare defects in a particular instance – damage both the anode and the separator in one battery cell. LG and Chevrolet have revised assembly and quality control steps to avoid these types of faults.
Now all dangerous electric cars will be replaced free of charge with an eight-year warranty (equivalent to 161,000 km), and for this LG will even increase the volume of their production at factories in Holland and Hazel Park (Michigan). True, no one specifies how many cars are in question and how many cars in general came out with those two defects.
There are also plans to develop more advanced diagnostic software that will allow you to closely monitor the condition of the battery and notify the owner about all abnormalities in work. The finished product will appear in two months, and it will be possible to install it only from authorized dealers.
Owners of the Chevrolet Bolt EV and EUV, whose batteries were released on time, will soon receive an invitation for a free repair. The recall campaign starts in mid-October.
