General Motors Calls E-Cars - Battery Cells Error-battery

General Motors Voluntarily expands the current recall of the Chevrolet Bolt eV to the remaining model year 2019 and all model year 2020-2022 vehicles, including Bolt EUV. Thus, it can be stated that GM has recalled all its e-cars to proceed accordingly against increased fire risk.

In rare cases, the batteries supplied to GM for these vehicles may have two manufacturing defects – a cracked anode tab and a folded separator – in the same battery cell, which increases the risk of fire. For caution, GM will replace the defective battery modules in the Chevrolet Bolt EVS and EUVs through new modules, which may cause additional costs amounting to about one billion dollars.

“Our focus on security and the right thing for our customers leads every decision we meet at GM. As a pioneer in switching to a fully electric future, we know that the construction and maintenance of confidence are crucial. The GM customers can rely on the need to take the necessary measures to ensure the safety of these vehicles.”- Doug Parks, GM Executive Vice President, Global Product Development, Purchasing and Supply Chain

Already in February 2021 we reported that GM is with its own callback from more than 68.000 vehicles employed in the USA. Even then, there was talk of problems in the battery cell. According to further investigations of manufacturing processes at LG and the decomposition of battery packs, GM discovered manufacturing defects in certain battery cells made in LG production facilities outside the factory in Ochang, Korea. GM and LG are working to fix the cause of these defects. In the meantime, GM strives for commitments from LG for the refund of this field action.

To calm the customers, the batteries with these new modules with a limited warranty of 8 years / 100.000 miles (or. 8 years / 160.000 Km delivered in Canada). It should be noted that the manufacturer cooperate intensively with LG to provide replacement batteries as soon as possible. Until it is so far, you should pay attention to the following as a driver of an EV BOLT:

  • Set the own e-car with the destination charging state mode to a limit of the state of charge to 90 percent. If customers are unable to successfully perform these changes, or do not feel sure to make these changes, GM asks for their own dealer to make these settings.
  • The vehicle should be charged more frequently. In addition, you should avoid that the battery falls below a residual length of 113 kilometers.
  • The vehicle is to be parked immediately after charging outdoors and not be charged overnight in closed rooms.

In Germany fall under the callback about 1.500 vehicles sold between 2017 and 2019 under the brand Opel and the model name Ampera-E. Worldwide is the speech of around 142.000 Vehicles of model years 2017 and younger by General Motors. There were similar problems already at Hyundai. Also with battery cells of LG.

    I suspect it is the built-in cells around Litium ion batteries!? If I read something from a burning Bev it’s always litium ion batteries.

    LFP should be safer – but under the circumstances mentioned, that could also happen with LFP batteries?
