Chevrolet has been unable to fix a severe battery fire issue in a timely manner, which effectively turns the Bolt EV a ticking time bomb that can potentially burn down my house, with my family's dead bodies in it. After multiple Bolt EV battery fires, GM acknowledged the issue first in Nov 2020, it took GM roughly half a year to come up with a software solution to "monitor" the batteries; during that half a year time period, we were told to limit our charge and park outside, without no assurance that the car wouldn't catch file when charging inside our garage. After receiving the "final" software remedy, two other Bolt EVs have caught fire, GM started another recall, with no solution and no timeline, and no assurance or credibility that they can provide a proper fix, my Bolt EV is turning into a ticking time bomb again. While charging outside of sleep hours lowers the chance of dying from fire, the risk of burning down our house is equal. We need GM to buy back the Bolt EVs while they figure out and apply a proper solution, instead of risking consumer's lives and properties to wait for the fix.

I currently lease a 2019 Chevrolet Bolt which is part of the recall announced today by GM. This is the second recall in less than a year for the same battery-related issue. It was supposed to have been fixed with a software update that I had completed in March. This software was supposed to identify defective batteries but it has not been successful as evidenced by the mounting number of fires that have happened after the “fix”. As such, we are now under a recall a second time. As a result of their own manufacturing issue, we are now limited to how we charge our vehicles, where we park and even the mileage range that we paid for, while GM attempts another fix. GM stated that they will again be using software to identify defective cells in our batteries and only the ones that are deternined to be defective will have those cells or battery packs replaced. As you can imagine, I no longer trust GM to be able to successfully identify whether or not my battery is defective. This is a serious safety issue. My family, my property and even people I park next to while out in public are at risk. GM must be forced to either replace the entire battery pack in every vehicle affected by this recall or replace them with newer models containing safer batteries. They must also provide loaner vehicles, or details on reimbursement for rental cars, to those who need them due to the fact that their vehicle is virtually unusable until GM provides a complete, effective solution.

I have a 2019 Chevy Bolt EV, with a potential for the High Voltage Battery to catch on fire. There was a first recall back in Nov. 2020, Manufacture states that there was a final fix for the High Voltage Battery. I took the vehicle in for the final fix. Recently there was a 2019 Chevy Bolt that caught on fire with the final fix for the recall. Now there’s a second recall for the same issues, now I can NOT park my car inside the garage and not charge it at night, because of a potential for the vehicle to change on fire. I have 2 boys that lives about the garage and I live in a Townhouse. This recall is a safety problems for everyone, it poses a safety risk while the vehicle is charging. The vehicle is a safety hazards to the public and building structures.

My Bolt falls under the recall for a main battery pack defect that has resulted in several car fires. Chevy states we should part outside our garage if the car is parked and charged there. This is a major inconvenience to owning the car. I requested a buyback several months ago when they were being offered by Chevy. Since Ohio's Lemon Laws are poor I was denied. I had little faith Chevy could find the problem with software and I was correct.

The battery in these vehicles is prone to catching on fire when charging, resulting in the complete destruction of the vehicle. GM has been failing to repair these vehicles for over a year. They have now issued a third recall for the same problem with no resolution and guidelines that require owners not to use their vehicles in any reasonable manner. This recall represents a serious danger to life and property, with a fire that could cost untold damages. These vehicles are unsafe, and GM is clearly unwilling or incapable of repairing the defect.
GM's recall solution is unacceptable and leaves consumers with virtually unusable vehicles if they follow GM's safety recommendations. This situation has been allowed to go on too long and we are lucky that no one has gotten hurt.

On May 11, 2021 I responded to GM's safety recall notice by bringing the car to a local Chevrolet dealer, who performed the service as per GM's instructions. Since then the battery has continued to charge or attempt to charge for several hours after it has been fully charged as indicated by the instrument panel readout and the dashboard indicator. I reported the problem to GM by phone several weeks ago and was instructed to bring the car back to the dealer that had performed the recall service. I did so on July 7 but I wasn't convinced that the dealer appreciated the seriousness of the problem, so I immediately called GM 's EV hotline (866-790-5600 ext. 5912316) where a case was opened. As of July 18 I am still waiting for further instructions from GM. My case number is 9-6818768332.

Component: We don't know for sure. The was a recall on the battery, and several other of these cars have had thier batteries explode in similar fashion. The primary remnants of the car are missing and are being investigated as being stolen and are unavailable for inspection. The melted remnants of the car left in the driveway are still available. Safety: We inhaled toxic vapors. Our home has been severely damaged. If the incident had happened in the middle of the night instead of in the morning, our neighbors wouldn't have been awake to call 911 and my wife and I could have died when the fire spread to the house. Has the problem been reproduced? Unknown, though this is a known issue that has happened to other cars. Has the compenent been inspected? No. The wreckage is missing and presumed stolen. Were there any warning messages: I do not believe so. My wife claims she heard a car alarm when we we awakened by the first loud noise. She does not know if the alarm came from our car. In the early AM of 7/2/2021 I awoke to smell an acrid smell. Our neighborhood often has an odd smell, so I went back to sleep. About 6 AM on 7/2/2021 my wife and I were awakend by a loud bang originating outside the house. I investigated and noted a police officer outside my home using a fire extinguisher on my 2019 Chevy Bolt. I saw flames coming from the right passenger side. The police officer asked us to exit our home. I told my wife that the house was on fire, because I believed that's what was happening. When we left the home, I noticed that, at first, it was only the car. The fire got worse very quickly., and the police officer asked us to move farther back.We heard and saw several explosions.The fire spread to the house. At some point the fire department arrived and extinguished the fire, but not before the car was completely consumed and significant damage was done to our home. My wife, I and our pets were all examined for smoke inhalation and the cats were treated.

My 2019 Chevrolet Bolt Premier has the battery made in Korea that is part of the current investigation Chevrolet is doing, announced yesterday July 14, 2021. This is the announcement from Chevrolet: JULY 14 2021 IMPORTANT UPDATE FROM GENERAL MOTORS General Motors has been notified of two recent Chevrolet Bolt EV fire incidents in vehicles that were remedied as part of the safety recall announced in November 2020. Out of an abundance of caution, we are asking owners of 2017-2019 Chevrolet Bolt EVs who were part of the recall population to park their vehicles outdoors immediately after charging and not leave their vehicles charging overnight while we investigate these incidents. This has been a known problem for several months, since November 2020, as noted in Chevrolet's announcement above. I limited my charging to 90% the minute the news broke about the possibility of a battery fire. I have had "the remedy" done to my car, which is all that one can do at this point. live in a condo building in a busy downtown setting and my only parking spot is two levels underground. It is both unsafe and very costly/inconvenient for me to have to park on the street at meters while waiting to hear ANYTHING from Chevy regarding next steps. I want to get my situation on your radar, as I am sure many other Bolt owners do. I want to stop worrying about the potential of a fire that would kill or maim any person or living creature, destroy any property, especially my home, my neighbors' homes, cars, etc. HELP!

In October 2020, the Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE) on 2017-2020 Model Year (MY) Chevrolet Bolt vehicles based on complaints received alleging that the vehicles caught fire under the seating area while parked and unattended. At the time, ODI had received 2 Vehicle Owner Questionnaires (VOQs) and several field reports. All complaints alleged vehicles caught fire during or after electrical charging.ODI's review found vehicle thermal events occurred during and/or at the end of the battery module charging cycle. The information learned from NHTSA and General Motors joint vehicle inspections prompted General Motors to file Recall 20V-701 on April 29, 2021. The remedy for this recall included 1) performing diagnostic procedures to identify and replace potentially defective battery cell-module assemblies and 2) installing onboard diagnostic software, designed to detect and warn owners regarding potential issues related to changes in battery module performance over time. Until this interim remedy became available for all affected vehicles, General Motors instructed their customers to enable ?Hilltop Reserve or ?Target Charge Level, based on the vehicle-equipped technology. Enabling these technologies would limit charging capacity of the battery module to a maximum of 90 percent. General Motors then continued to investigate the root cause of these battery cell module thermal events, which would lead them to their long-term recall remedy solution. Utilizing the information obtained from the Recall 20V-701 software update, General Motors and LG Energy Solutions,the supplier of the battery cell module pack along with LG Electronics,determined the root cause of the thermal events to be the result of two simultaneous manufacturing defects occurring in the same battery cell. The defect condition appears to be aggravated by routinely charging the battery to a full or nearly full state of charge after it has been substantially depleted. The two defects, located within the same battery cell module, would cause an internal short within the battery pack, resulting in the thermal events. The manufacturing process was changed to prevent the occurrence of these two defect conditions.On July 24, 2021, General Motors filed a defect information report recalling all 2017-2018 Chevrolet Bolt and certain 2019 Chevrolet Bolt vehicles with design level N2.1 battery cell produced at the LG Ochang, Korea plant. This remedy replaces defective battery cell-modules and will prevent potential thermal events from occurring during and/or at the end of the charge cycle. The recall (21V-560) includes vehicles that were remedied under 20V-701.General Motors continued to review new data after Recall 21V-560 and learned of an incident that occurred outside of the scope of the recall population. Additional analysis led General Motors and LGES to determine that the manufacturing defects defined by Recall 21V-560 were not isolated to one battery manufacturing plant. On August 21, 2021, General Motors filed a defect information report to expand the scope of recall 21V-560. The recall (21V-650) includes all 2019-2022 Chevrolet Bolt EV and 2022 Chevrolet Bolt EUV vehicles. In view of the recall actions being taken by General Motors, ODI is closing this Preliminary Evaluation. NHTSA reserves the right to take additional action if warranted by future circumstances.The ODI reports cited above can be reviewed online at nhtsa.gov under the following identification numbers:11230072, 11425524, 11339878, 11365622, 11364692, 11427180, 11429891, 11374956, 11407212, 11372429, 11425225, 11415800

All complaints alleged vehicles caught fire during or after electrical charging.ODI's review found vehicle thermal events occurred during and/or at the end of the battery module charging cycle. The information learned from NHTSA and General Motors joint vehicle inspections prompted General Motors to file Recall 20V-701 on April 29, 2021. The remedy for this recall included 1) performing diagnostic procedures to identify and replace potentially defective battery cell-module assemblies and 2) installing onboard diagnostic software, designed to detect and warn owners regarding potential issues related to changes in battery module performance over time. Until this interim remedy became available for all affected vehicles, General Motors instructed their customers to enable ?Hilltop Reserve or ?Target Charge Level, based on the vehicle-equipped technology. Enabling these technologies would limit charging capacity of the battery module to a maximum of 90 percent. General Motors then continued to investigate the root cause of these battery cell module thermal events, which would lead them to their long-term recall remedy solution. Utilizing the information obtained from the Recall 20V-701 software update, General Motors and LG Energy Solutions,the supplier of the battery cell module pack along with LG Electronics,determined the root cause of the thermal events to be the result of two simultaneous manufacturing defects occurring in the same battery cell. The defect condition appears to be aggravated by routinely charging the battery to a full or nearly full state of charge after it has been substantially depleted. The two defects, located within the same battery cell module, would cause an internal short within the battery pack, resulting in the thermal events. The manufacturing process was changed to prevent the occurrence of these two defect conditions.On July 24, 2021, General Motors filed a defect information report recalling all 2017-2018 Chevrolet Bolt and certain 2019 Chevrolet Bolt vehicles with design level N2.1 battery cell produced at the LG Ochang, Korea plant. This remedy replaces defective battery cell-modules and will prevent potential thermal events from occurring during and/or at the end of the charge cycle. The recall (21V-560) includes vehicles that were remedied under 20V-701.General Motors continued to review new data after Recall 21V-560 and learned of an incident that occurred outside of the scope of the recall population. Additional analysis led General Motors and LGES to determine that the manufacturing defects defined by Recall 21V-560 were not isolated to one battery manufacturing plant. On August 21, 2021, General Motors filed a defect information report to expand the scope of recall 21V-560. The recall (21V-650) includes all 2019-2022 Chevrolet Bolt EV and 2022 Chevrolet Bolt EUV vehicles. In view of the recall actions being taken by General Motors, ODI is closing this Preliminary Evaluation. NHTSA reserves the right to take additional action if warranted by future circumstances.The ODI reports cited above can be reviewed online at nhtsa.gov under the following identification numbers:11230072, 11425524, 11339878, 11365622, 11364692, 11427180, 11429891, 11374956, 11407212, 11372429, 11425225, 11415800
