GM Warns Chevrolet Bolt Owners Of Fire Risk


General Motors is advising owners of older Chevrolet Bolts to park them outdoors and not leave them charging at night because the two electric vehicles caught fire after being repaired as part of a recall campaign.

The automaker said Wednesday that the request concerns the 2017-2019 Chevrolet Bolt, which had been withdrawn earlier due to battery fires. According to GM spokesman Kevin Kelly, the latest request came after two electric cars that were repaired after the recall caught fire, one in Vermont and the other in New Jersey.

According to its brand representatives, owners should take steps “out of great caution.” According to him, it is necessary to be careful until GM engineers investigate and develop a repair program.

In April, GM announced that it has developed diagnostic software to find battery anomalies in 69,000 electric vehicles worldwide. If problems are found, the company will replace the defective battery parts.

In November, GM recalled electric vehicles after reports of several incidents of battery fires. At first, the company did not know what was causing the problem, but determined that the ignited batteries were almost fully charged. As a temporary solution, owners and dealers have been asked to make software changes to limit charging to 90% of the battery’s capacity.

GM linked the fire to a so-called rare manufacturing defect in battery modules. This could cause a short circuit in the cell, which could cause a fire. Under this remedy, dealers were required to install software designed to alert owners of problems, and any defective items were to be replaced.

The recall came after the US National Highway Traffic Safety Administration launched an investigation into the fires last year. Agency documents say the fire started under the rear seat when the cars were parked and left unattended.

Engineers determined that the fires occurred at Bolt with battery cells manufactured at LG Chem’s Ochang, South Korea plant from May 2016 to May 2019. Some 2019 EVs and all 2020 and 2021 versions have cells made at LG Chem’s Holland Michigan plant and are not included in the recall.
