What is the cause of the defect? Will it replace the entire battery pack? Is it all GM Bolt EVs, or just some?
GM said about 73,000 vehicles in the U.S. and Canada are being added to the recall from the 2019-2022 model years, including a recently launched larger version of the car called the Bolt EUV. The former recall involved about 69,000 of the cars globally from the 2017-2019 model years, including nearly 51,000 in the U.S.
General Motors, the largest US automaker, has announced the recall of its Chevrolet Bolt EV, which was recalled in November by General Motors after five reported fires and two minor injuries covered 2017-2019 Chevrolet Bolt EVs with high-voltage batteries produced in LG Chem Ltd (051910.KS) Auchang, South Korea facility.
According to Reuters.

GM said dealers will use “diagnostic tools to identify potential battery abnormalities and replace battery unit assemblies as necessary.”
They will install “advanced diagnostic software on board these vehicles with, among other things, the ability to detect potential problems related to changes in battery module performance before problems develop.”

General Motors said in November that vehicles posed a fire hazard when charged to full or nearly full capacity.
The Detroit automaker said it has developed a program that will limit the vehicle’s charge to 90% of full capacity to mitigate risks, while it outlines an appropriate final repair.
GM said in an official statement released Thursday
that once the software update is complete, dealers will remove 90% of the charging restrictions and return the battery to its previous 100% charging capacity.

Owners of 2019
Chevrolet Bolt EVs will be able to update the software starting Thursday, and 2018 Bolt EV owners will be eligible by the end of May.
GM said it will make the diagnostic software standard on the 2022 Bolt EV and EUV, as well as GM’s future electric vehicles, and will offer the update to all other Bolt EVs on the road at a future date.
Previously, the Inside EV website had submitted several complaints to General Motors, requesting an explanation for the burning of several Bolt cars for no apparent reason. On the other hand, the famous Cars website in the world of cars published the five safety reports issued against the burned cars, and
you can view these reports from here .

General Motors has promised InsideEVs that it will answer its questions once it has more information about why Chevy Bolt EVs automatically catch fire.
The company spoke to Automotive News and sent out a safety recall report known as NHTSA for Part 573, which invites General Motors to answer all questions.
However, the site stated that it did not respond to them in both cases sent from the site, and the site demanded that General Motors respond to it, saying: We did not hear anything.
These are the questions GM has to answer.
Causes of a Chevy Bolt EV spontaneously burn out

The most pressing question concerns the investigation of the cause of the fires.
The company said: “One or more rare manufacturing defects inherent at the cell level in design level N2.1 batteries produced at LG Chem’s facility at its Ochang, Korea plants.”
If you’re asking about flaws, you’re not alone.
We are like you ask GM.
There were rumors of a problem with the cell separator on Bolt batteries causing the problem, but GM quickly dismissed the possibility of a cell separator issue once rumors spread that this would be the case for the Hyundai Kona Electric fires that began to spread.
Both Hyundai Kona Electric and Chevy Bolt models are based on the same battery provider: LGES (LG Energy Solution), formerly LG Chem.

In the end, Hyundai revealed that the defect was caused by a folded anode tab, limited to batteries made at the LGES Nanjing plant in China.
On the other hand, LG denied any problems related to its batteries, and Hyundai said that it bears responsibility and began to take back.
Rumor has it that the Korean automaker paid LGES to bear 70 percent of the cost of replacing defective battery packs, but neither company has confirmed this.
GM has been more diplomatic in recalling it, perhaps because LGES is a partner in the future Ultium plants the US automaker plans to build.
The
two companies already have plans for two of these plants: one in Ohio and one in Tennessee .
This may be one reason why the exact cause of the fires has not been revealed.

If the anode tab is folded, Kona electric units equipped with LGES cells made at the Ochang factory could also be the problem.
It is reported that Hyundai has already abandoned the sale of Kona Electric in South Korea due to the damage to its reputation.
Several media outlets demanded that General Motors explain to its customers how to carry out the repairs.
The auto news site published all the safety reports from Part 573, without comment, and the company said it would “implement diagnostic procedures.”
While several media outlets demanded that General Motors know what was tested and how effective these tests were in preventing new fires.
If the Bolt EV had the same defect as the Hyundai Kona Electric, then either Hyundai was too cautious, or GM was ignoring the risks.

Harnal Mutzer did not announce the length of Bolt’s recall
Perhaps the bitter truth that prompts us to calculate the element of time is due to the fact that the battery in electric cars is located in the arms of the chassis under the driver and passenger, and this means that the entire car will be dismantled, and in the event that “the battery unit groups that fail to diagnose” are replaced “if necessary.”
This is a big problem.
The problem is that the Bolt EV battery pack is sealed like the one used by Tesla.
Replacing unit assemblies instead of battery packs as Hyundai does will require disassembling defective battery packs, which will take a long time.
But GM did not inform its customers or the media about how long the repair process would take.
And out of Mallaky.com’s commitment to credibility, we re-publish
the official statement published by General Motors on the Chevrolet website as it is and as follows:
General Motors is notifying owners of 2017-2019 Chevrolet Bolt electrified vehicles that it has developed a remedy to complete the previously announced safety recall.
As part of the service procedure, dealers will use GM-developed diagnostic tools to identify potential battery abnormalities and replace battery unit assemblies as necessary.
The treatment will also include the installation of advanced on-board diagnostic software in these vehicles which, among other things, has the ability to detect potential problems related to changes in the performance of the battery module before problems develop.
Customers will need to visit the nearest participating Chevrolet EV dealer to carry out repair service procedures.
Once the treatment procedure is complete, the agent will remove the 90% charge limit and return the battery to its previous 100% charging capacity.
Customers of 2019 Chevrolet Bolt EVs will be able to have this treatment beginning April 29
, and customers who own 2017 and 2018 Bolt EVs will be eligible for the treatment by the end of May.
We will also be making advanced diagnostic software available to all other Bolt EV owners in the coming months.
In addition, we will standardize this diagnostic software on 2022 Bolt EV and EUV, as well as future GM electric vehicles.
The text of the statement has ended, and we notify all our readers of the need to immediately go to the power of attorney for Chevrolet Motors in their countries
