General Motors (GM), a stalwart in the automotive industry, has embarked on an ambitious journey towards electrification with its Ultium architecture. This innovation aims to span across various market segments, from the practicality of the next-generation Chevrolet Bolt EV to the opulent luxury of the Cadillac Celestiq. However, GM’s transition to electric vehicle (EV) dominance has hit a roadblock as it grapples with obstacles in ramping up production. The company’s Chief Financial Officer (CFO), Paul Jacobson, recently acknowledged the difficulties in meeting the desired production capacities for their electrified lineup.

Ramping Up Production Woes

Despite a robust pipeline of Ultium-based EVs, the majority of these vehicles are yet to roll off the production line. Even those that have commenced production are struggling to attain their intended manufacturing volumes. According to a recent Reuters report, GM’s CFO, Paul Jacobson, divulged at a J.P. Morgan investor conference that the company is still encountering challenges in increasing the production of electric vehicles. This applies to a range of models, from the elegant Cadillac Lyriq to the utilitarian Brightdrop Zevo 600 van.

Assembly Woes and Battery Module Issues

The predicament revolves around an issue with assembling battery modules, as revealed by CEO Mary Barra during a second-quarter earnings call. In fact, the situation became so dire that GM had to temporarily shutter one of its plants, the CAMI Assembly in Ontario, Canada, for two weeks in July. The shutdown was attributed to a reported shortage of batteries, an essential component in the production of electric vehicles.

Lyriq’s Disappointing Production Numbers

Paul Jacobson disclosed that GM managed to produce just over 1,000 Lyriq SUVs in July. This figure, however, falls considerably short of the company’s initial expectations. Initially aiming to manufacture 25,000 units of the Lyriq in the previous year, GM’s Spring Hill, Tennessee plant fell well below the mark, producing only 8,195 units.

A Challenging Year

Unfortunately, the production woes extended into the current year. GM’s delivery of Lyriq SUVs during the first half of 2023 amounted to less than 2,400 units. This underwhelming figure can be attributed to ongoing battery and supply-related challenges. The situation doesn’t look promising for other eagerly anticipated models either, such as the GMC Hummer EV Pickup and SUV. In the first half of 2023, GM managed to deliver a mere 49 units of these vehicles.

A Glimpse of Hope

In a bid to tackle the production challenges head-on, GM resumed production of the BrightDrop Zevo 600 van on July 31 at its plant in Ingersoll, Ontario. Additionally, the company is embarking on an expansion project at the same facility. This expansion aims to enable the on-site assembly of Ultium batteries by the second quarter of 2024. These batteries will be sourced from GM’s Ultium Cells plants, then assembled into battery packs at CAMI, where they will be integrated into BrightDrop vans or shipped to other EV production sites.


As GM navigates the intricate terrain of electrification, the journey is not without its challenges. The acknowledgment by CFO Paul Jacobson regarding the difficulties in ramping up EV production sheds light on the complex nature of transitioning to an electric future. While setbacks are evident, GM’s commitment to addressing these issues, coupled with its strategic partnerships, may well pave the way for the realization of its electrification dreams powered by the Ultium architecture.
