Production difficulties plagued multiple facilities making Chevy and GMC trucks during August, with both reduced production and complete production halts affecting several GM plants from Mexico to Canada during the later summer of 2023.
In all cases, shortage of parts from third-party suppliers made inroads into the number of Chevy and GMC pickups produced, though the severity of the effects varied from location to location.
Lack of components forced The General to idle the 26.5-million square-foot GM Silao plant in Silao, Guanajuato, Mexico between August 11th and August 28th, or around 17 days. Models affected included the popular Chevy Silverado 1500 and GMC Sierra 1500 full-size pickup trucks.
The August stoppage at Silao is the second to occur this year, with a two-week shutdown also reported in March and ending on March 21st. GM representatives noted that strong demand for the truck models produced at the site continued, and that lack of parts from a supplier or suppliers was the only reason for idling production. The representatives did not say which parts were unavailable.
Difficulties in obtaining enough parts has also prompted GM to reduce production at the GM Wentzville plant in Missouri, running only two shifts per day rather than three during the week of August 28th, 2023 to September 5th, 2023. Among the models affected are the Chevy Colorado, GMC Canyon, Chevy Express and GMC Savana trucks and vans.
Meanwhile, the GM Fort Wayne plant in Indiana says that all “production is canceled for the week of August 28th due to a temporary part shortage,” and is expected to resume on September 5th, the same timetable as the Wentzville slowdown. The Fort Wayne facility makes Chevy Silverado 1500 and GMC Sierra 1500 pickup trucks, similar to the Silao, Mexico plant.
Finally, the GM Oshawa plant in Canada experienced a shortage of axles for GM light-duty pickups, which The General says is unrelated to the other parts supply constraints.
Fort Wayne production was also stopped for two weeks in March and April 2023. However, this was prompted by oversupply of Chevy and GMC trucks, which reached a backlog of 100 days supply at times earlier in the year and still had roughly 80 days supply in June at a time when the Chevy brand had 50 days supply overall.
