Certain full-size GM SUVs will no longer offer the Electronic Steering Column Lock feature. Exclusion of the feature is due to the ongoing global microchip shortage.
The GM SUVs affected by this change include the 2021 Chevy Tahoe, 2021 Chevy Suburban, 2021 GMC Yukon / Yukon XL, and 2021 Cadillac Escalade / Escalade ESV, each of which introduce a brand-new generation for the 2021 model year.
Production of those GM SUVs that no longer include the the Electronic Steering Column Lock feature began on July 5th, 2021. The exclusion of the Electronic Steering Column Lock feature enables continued production of the full-size GM SUVs to help meet strong customer and dealer demand.
Affected GM SUVs with a scheduled production date on or after July 5th will be tagged with RPO code R7N, indicating that they are not equipped with the Electronic Steering Column Lock feature. Affected models will also include a $50 MSRP credit.
The change in availability for the Electronic Steering Column Lock feature is expected to remain in place for the remainder of the 2021 model year.
The microchip shortage has affected the entirety of the automotive industry, with widespread production cuts and reduced feature availability all around the world. One estimate in May put the affected GM production numbers at 278,000 fewer units globally.
In order to alleviate the impact of the microchip shortage with regard to its most in-demand vehicles, General Motors has continued to build models without certain features. This includes the deletion of the automatic engine stop-start feature from full-size GM SUVs equipped with either the naturally aspirated 5.3L V8 L84 or 6.2L V8 L87 when mated to the GM 10-speed automatic transmission. Models equipped with the 3.0L I6 LM2 turbodiesel Duramax are not affected by the removal of automatic engine stop-start.
