GM’s EV ramp-up affected by automation supplier delays

General Motors Co. is experiencing issues with automation supply for battery module production, which is slowing its electric vehicle production ramp-up, executives told investors.

CEO Mary Barra said Tuesday that the automaker has experienced “unexpected delays” because an unnamed automation equipment supplier has struggled with “delivery issues that are constraining module assembly capacity.”

GM's Ultium platform undergirds the upcoming Silverado, Equinox and Blazer EVs.

The hiccup in production comes as GM is in the midst of a breakout year for its EVs based on its new Ultium electric platform, with launches planned for the electrified versions of three popular Chevrolet products: the Silverado, Equinox and Blazer.

Barra stressed the automaker still intends to meet its stated EV production goals of 100,000 units built by the end of 2023 in North America and 400,000 by the middle of next year. GM did meet its target of making 50,000 EVs in the first half of the year.

“What you’re going to see in the second half of this year — and then really crank up in the first half of next year — is a lot more Ultium-based products,” Barra said.

She added that GM thought the supplier was “on track for the delivery that they had.”

“We’ve already seen a lot of improvement from, I’ll say, the last four-to-six weeks,” she said. “We’re going to continue on that path.”

GM has sent manufacturing engineering teams to help the automation supplier improve its delivery. The Detroit automaker has also added manual module assembly lines at its EV plants.

To ensure its coming launches are not affected by the issue, GM is installing additional module lines first at its Factory Zero Detroit-Hamtramck Assembly Center and Spring Hill, Tennessee, plant this summer, then at its Ramos Arizpe plant in Mexico this fall, and lastly its CAMI plant in Ontario in the second quarter of 2024.
