Sources close to the matter tell GM Authority that the LPO or dealer-installed illuminated front and rear door sill plates (RPO code S0M) are unavailable to order on either the 2023 Tahoe or 2023 Suburban. This option was normally offered on LT, RST, Z71, Premier and High Country trim levels for an extra $615. Notably, it was never offered on the LS trim.
It’s worth noting that this means the LPO-level Illumination Package (RPO code RGL) is unavailable as well, as the door sill plates are included as part of the package that rounds up:
- Illuminated mirror Chevrolet emblem, LPO (RPO code S3I)
- Illuminated front door sill plates, LPO (RPO code S0M)
- Illuminated liftgate sill plate, LPO (RPO code 5RU)
As a reminder, the 2023 Chevy Tahoe and 2023 Chevy Suburban are offered with several powerplant options, including the atmospheric 5.3L V8 L84 gasoline engine, the atmospheric 6.2L V8 L87 gasoline engine, and the 3.0L I6 LM2 turbodiesel Duramax engine.
For those who may be unaware, the 2024 Tahoe and 2024 Suburban are set to receive a mid-cycle refresh that will bring about a suite of exterior, interior and technological updates. Besides a few minor details gleaned from our recently published spy shots, not much else is known the upcoming revisions, although GM Authority reported last December that production is expected to kick off sometime in November 2023 at the GM Arlington plant.
