GM Releases Fix For Inoperative 2022 GMC Sierra 1500 Trailer Brake Function

General Motors has issued a Customer Satisfaction Program for certain 2022 GMC Sierra 1500 units due to a problem with the trailer brake.

According to Customer Satisfaction Program N242442100, select examples equipped with the Integrated Trailer Brake (RPO code JL1) feature may have a condition where the trailer brake function is inoperative. To rectify this issue, certified GM technicians have been instructed to inspect affected pickups and install a new integrated trailer brake control switch on the instrument panel, as well as reprogram the Instrument Panel Cluster (IPC) and Electronic Brake Control Module (EBCM). All told, it should take techs a little less than three hours to perform this fix.

It’s worth noting that this feature was optional on Pro, SLE, Elevation and SLT trim levels, and standard on the AT4, AT4X, Denali and Denali Ultimate. Finally, it’s currently unclear how many units are affected by this issue.

In other Sierra 1500-related developments, the upcoming 2025 model year is just around the corner, and will feature a few minor changes to Big Red’s full-size pickup truck. One of these updates includes a reshuffling of the available paint options, as the 2025 Sierra 1500 will lose two paint colors.

As a reminder, the GMC Sierra 1500 is available with a plethora of powerplants offerings, including the turbocharged 2.7L I4 L3B gasoline TurboMax engine, rated at 310 horsepower and 430 pound-feet of torque, the naturally aspirated 5.3L V8 L84 gasoline engine, rated at 355 horsepower and 383 pound-feet of torque, the naturally aspirated 6.2L V8 L87 gasoline engine, rated at 420 horsepower and 460 pound-feet of torque, and the 3.0L I6 LZ0 turbodiesel Duramax engine, rated at 305 horsepower and 495 pound-feet of torque.

In regard to transmission options, the L3B is matched to the GM eight-speed automatic, while the L84, L87, and LZ0 engines are all mated to the GM 10-speed automatic. Both RWD and 4WD configurations are on offer.

Under the body panels, the GM T1 platform provides the underpinnings, while production takes place at the GM Fort Wayne plant in Indiana and the GM Silao plant in Mexico.
