This is one of the many supplier constraint issues currently facing General Motors, and as with several others recently announced, it may not be resolved during the remainder of the 2021 model year. It is also unclear whether the tonneau cover will once again be available to order when the 2022 GMC Sierra 1500 goes on sale, likely in the third quarter of the 2021 calendar year.
The tri-fold hard tonneau cover is still shown on the GMC Sierra 1500 configurator, but likely not for long. The cover has the RPO code VOZ and normally costs $1,100. It was offered on Crew Cab Short Box and Crew Cab Standard Box configurations, and in the SLT, AT4 and Denali trim levels, but not the SLE, the Elevation or the base Sierra.
The tri-fold soft tonneau cover, which has the RPO code 63B and is priced at $700, is also still listed on the configurator and, unlike the hard cover, remains available to order. However, the same item is no longer offered for the Sierra’s corporate cousin, the 2021 Chevy Silverado, due to another supplier constraint issue. It may only be a matter of time before we have to announce similar news for the GMC Sierra.
Whatever the situation regarding accessories may be, the Sierra 1500 is expected to receive a significant refresh, known as a mid-cycle enhancement (or MCE) for the 2022 model year. This is likely to include new front and rear fascia designs, an revised cabin (with no column shifter), a migration to Google Automotive Services, the introduction of the Super Cruise semi-autonomous driver assist system as an option on the range-topping Denali and an increase in payload and towing capacities.
Production will take place, as now, at the GM Flint Assembly plant in Michigan, the GM Fort Wayne Assembly plant in Indiana, the GM Silao Assembly plant in Mexico and, from 2022, the re-opened GM Oshawa Assembly plant in Ontario, Canada.
