Chevrolet Bolt Airbag And Battery Problem

Posted on by

General Motors will be contacting the owners of certain Chevrolet Bolt EVs and EUVs for two separate problems. A small number of 2022 Chevy Bolt EVs and EUVs may have been manufactured with improperly tightened or missing airbag fasteners and approximately 50,413 2017-2019 Chevy Bolt EVs are at risk of a battery fire.

2022 Chevy Bolt EVs and EUVs Airbags Improperly Installed: In June 2021, a GM quality manager submitted a report to GM’s Speak Up For Safety program following reports of vehicles missing steering wheel airbag fasteners that caused the airbag cover to be poorly seated. GM determined that these vehicles were taken off-line during manufacturing and the technician did not fully complete installation of the steering wheel airbag. The issue was reviewed by GM’s Open Investigation Review and GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall.

Dealers will inspect the driver airbag fasteners, replace any missing fasteners and assure that all fasteners are properly installed. If proper torque can not be achieved, the driver airbag assembly will be replaced. GM’s number for this recall is N212343880 and the NHTSA campaign number is 21V-560.

2017-2019 Chevy Bolt EV Battery Fire: The condition is specific to vehicles involved in NHTSA recall 20V-701. Through additional investigation, GM have now identified the cause, and are commencing a new recall to replace defective battery modules in the recall population.

The cause is the presence of two rare manufacturing defects in the same battery cell in design level N2.1 batteries produced at LG Chem’s Ochang, Korea facility. The 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 battery may overheat, emit smoke and could damage other vehicle components.

Defective battery modules will be replaced by GM, free of charge. Interim notifications are expected to be mailed September 6, 2021. A second letter will be mailed once the final remedy is available. GM’s number for this recall is N212343880 and the NHTSA campaign number is 21V-560.

GM Software To Prevent EV Battery Fires

Posted on by

General Motors will be contacting owners of select 2017-2019 model year Chevrolet Bolt EVs previously repaired under National Highway Traffic and Safety Administration (NHTSA) campaign number 20V-701.

The problem began in October 2020 when the NHTSA started an investigation into owner complaints of battery fires while their Bolt EV was charging. To reduce the risk of fires, GM provided a temporary fix in which the the vehicle’s software was updated to limit it’s charge to 90% of the battery’s capacity.

As part of the final repair, dealers will use diagnostic tools to identify potential battery anomalies and replace battery module assemblies as necessary. The fix will also include the installation of advanced onboard diagnostic software that detects potential issues related to changes in battery module performance. Customers will need to visit their Chevrolet EV dealer to have the service procedure performed. Once the remedy procedure is completed, the dealer will remove the 90% state of charge limitation and return the battery to its previous 100% charging capability.

Customers of 2019 model year Chevrolet Bolt EVs will be able to have this fix performed starting on April 29 and customers who own 2017 and 2018 model year Bolt EVs will be eligible to have the remedy performed by the end of May. GM will be making this diagnostic software standard in the 2022 Bolt EV and EUV future electric vehicles. According to GM, if a problem is diagnosed, the software will warn the driver with an illuminated warning lamp on the gauge cluster and drivers would need to have the vehicle towed to a dealer for repairs.

Posted on by

Hyundai Motor America will be asking owners of certain 2020 Hyundai Ioniq Electric and 2019-2020 Hyundai Kona Electric vehicles to return to their dealerships because of a problem affecting the lithium-ion battery.

In March 2019 Hyundai received three reports of Kona electric vehicles catching fire while parked. All vehicles involved were reportedly parked with a fully charged battery. Further investigation found several similar incidents which initiated an investigation into the problem. As a result of this investigation, a campaign was launched to upgrade the BMS software for early detection of abnormalities in the battery while the vehicle is parked. The software update was developed as a fail safe countermeasure as they continued their investigation

In February 2021 Hyundai became aware of a Kona EV. with the updated software. that caught fire while at full state of charge. Further investigation into the cause found an internal short within the battery cells caused by a folded Anode tab could result in Lithium plating on the Anode tab to contact and short circuit to the Cathode. Based on this information a safety campaign will be conducted to replace the Battery System Assembly (BSA)

Once parts are available, dealers will replace the Battery System Assembly (BSA). Owners are advised to park their vehicles outside and away from structures until the recall is complete. The recall is expected to begin end of April. Hyundai’s number for this recall is 200 and the NHTSA campaign number is 21V-127.

In October 2020 the National Highway Traffic and Safety Administration (NHTSA) started an investigation of the Chevrolet Bolt EV because of potential battery fires while charging. In November, Chevrolet announced a recall affecting 2017-2018 and select 2019 Chevrolet Bolt EVs manufactured by LG Chem’s Ochang Korea facility. More than 68,000 Chevy Bolt EV’s have been recalled.

The safety recall from the NHTSA states the following:

As an interim remedy, dealers will reprogram the hybrid propulsion control module 2 9HPCM2) to limit full charge to 90%. Until this interim reedy is completed, customers should enable either “Hilltop Reserve” )for 2017-2018 model year vehicles) or “Target Charge Level” (for 2019 model year vehicles) using their vehicle’s infotainment center. These two features will limit the vehicle’s state of charge to 90% until the HPCM2 software re-calibration is applied. If customers are unable to successfully make these changes, or do not feel comfortable making these changes, they will be advised to not park their car in their garage or carport until after they have visited their dealer.

Pursuant to 49 C.F.R. 573.13(d)(1), all covered vehicles are under warranty, so reimbursement is not offered.

The revised software will limit the vehicle’s full charge to 90% of the battery’s capacity.

Design level N2.1 battery cells wre no longer used in production after 2019 model year.

The final remedy is still under development. Owners were notified of the interim repair beginning November 17, 2020. A second notice will be mailed when the final repair becomes available. GM’s number for this recall is N202311730 and the NHTSA campaign number is 20V-701 .

Chevrolet Bolt Investigated For Battery Fires

Posted on by

The National Highway Traffic Safety Administration (NHTSA) have opened an investigation into certain 2017-2020 Chevrolet Bolt electric cars after several complaints of vehicle fires. The NHTSA says it was contacted by two owners who reported that their Bolt EVs caught fire while parked and unattended. In one case the vehicle was plugged into a charger in the owner’s driveway when it caught fire. The second vehicle was parked but not plugged in approximately 20 minutes after being driven, before it caught fire. Additional research by the Office of Defects Investigation (ODI) found a third vehicle, a 2017 Bolt EV with a similar burn patterns.

In all three cases, fire damage appeared to come from the battery compartment with fire passing into the passenger compartment from under the rear seat. The root cause of the fires is unknown and the ODI is opening a “preliminary evaluation” into the matter. If the investigation results in a vehicle recall, approximately 78,000 Chevy Bolt EVs would be affected.
