Back in January 2023, GM Authority reported that the 2024 Chevy Silverado HD would receive limited 12-volt power outlet availability. Now, another feature will be under constraint for certain trim levels, namely the rear-seat USB ports.
GM Authority has learned that the rear-seat USB ports (RPO code UBI) are currently under constraint. Affected vehicles will be indicated as such with RPO code RFO on their window sticker. As of the time of this writing, it’s unclear if there will be a dealer retrofit available later on, although it is unlikely.
As context, the rear-seat USB ports are normally optional on the Work Truck (WT) trim, but required the optioning of the 120-volt interior power outlet (RPO code KI4), which in turn required choosing the WT Convenience Package (RPO code PCV). As for the Custom trim level, the rear-seat USB ports are normally included and only available with the KI4 feature, which itself required the optioning of the Custom Convenience Package (RPO code PCX).
In regard to the LT trim, the rear-seat USB ports are normally included and available with the KI4 option. Finally, the rear-seat USB ports are standard on LTZ and High Country trim levels. Notably, these range-topping trims are unaffected by the constraint, and will thus continue to receive the feature.
Under the hood, the 2024 Silverado HD utilizes the 6.6L L8T V8 gasoline engine as standard fare, while the 6.6L V8 L5P turbodiesel Duramax engine is optional. The Duramax has been uprated to 470 horsepower and 975 pound-feet of torque as part of the redesign.
