The chip shortage has affected practically all GM vehicles to some degree. The company is manufacturing any vehicle with heated and ventilated seats without that feature, though with a future retrofit available. It is also omitting stop-start technology from a range of SUVs and pickup trucks because of insufficient semiconductors, Car and Driver says. These include the popular Chevy Silverado and GMC Sierra, plus the GMC Yukon, Chevy Suburban and Tahoe, and Cadillac Escalade.
Approximately 95,000 GM vehicles of unspecified model, but possibly including EVs, are currently unfinished as reported by Inside Indiana Business. These vehicles are warehoused, awaiting the chips needed to complete them and send them on to dealerships.
