GM temporarily halts Orion Assembly amid massive Chevy Bolt recall

The massive global recall of all Chevrolet Bolt EVs and EUVs has prompted General Motors to shutter the plant that makes the vehicles until Sept. 6. 

GM had idled Orion Assembly, the plant where it assembles the Bolt EVs and EUVs, this week due to a global shortage of semiconductor chips used in a variety of car parts. The shortage is impacting the entire auto industry with GM and others having to idle plants, reduce shifts or partially build vehicles until more chips are available.

GM's Orion Assembly builds the all-electric Chevrolet Bolt used for testing its GM Cruise self-driving fleet.

GM said Thursday it is extending the downtime at Orion Assembly an additional two weeks as a result of a battery pack shortage related to the recently announced Bolt recall.

GM and battery maker LG Chem are still investigating what caused manufacturing defects that resulted in at least 10 Bolts catching fire. 

“We are extending downtime to include the weeks of Aug. 30 and Sept. 6,” said Dan Flores, GM spokesman, in a statement. “We will continue to evaluate additional production schedule adjustments.”

About 1,000 hourly workers build the Bolt vehicles and the Cruise AV test vehicles at Orion Assembly in Lake Orion.

During a media roundtable Thursday, UAW President Ray Curry was asked about the recall’s role in shutting down the plant and what it will mean for union members.

“That’s a discussion that is just really getting started and ongoing at this point,” Curry said, adding that because it is a national recall he cannot elaborate on any discussions between the union and GM.

Last week, GM issued a new recall that expands to all Bolt EVs and the new EUV for fire risk. The automaker said it will provide customers with an eight-year warranty or 100,000 miles on new battery modules for the affected cars.

GM said it expects the recall to cost it $1.8 billion and is seeking reimbursement for some of that cost from LG Chem. The high-voltage batteries used in the Bolts are made by LG Chem’s Ochang, South Korea, facility. GM said it also discovered manufacturing defects in certain battery cells produced at LG manufacturing facilities beyond the Ochang plant.

In an interview with Bloomberg Television Thursday, GM CEO Mary Barra indicated that GM will continue its relationship with LG. 

Barra has said the battery defects are limited to the Bolt. GM’s upcoming EVs will be on its new proprietary Ultium battery platform, which it developed with LG Energy Solution. It will power the GMC Hummer EV pickup due to market later this year and the Cadillac Lyriq SUV to come next year.
