Chevy LCF 5500 Recalled For ABS Module Calibration Issue

GM has issued a product recall for certain examples of 2022 and 2023 Chevy LCF or Low Cab Forward 5500 HD/XD vehicles due to a problem with the ABS (Antilock Brake System) module.

The problem: vehicles with a 200-inch wheelbase or 212-inch wheelbase may have an Antilock Brake System (ABS) module that was not calibrated to function with the truck’s longest wheelbase lengths.

The hazards: 2022 or 2023 Chevy LCF 5500 trucks with the incorrectly calibrated ABS module may experience erroneous input from the cameras for the ADAS (Advanced Driver Assistance System) as well, causing the ADAS to respond incorrectly to actual driving conditions and potentially cause a crash.

While driving on a curve, the Automatic Emergency Braking system (AEB) may delay braking incorrectly, resulting in aggressive braking once the system does activate. Adaptive Cruise Control (ACC) (RPO code KSG) may reduce following distance by 26 to 33 feet (8 to 19 meters), following the vehicle in front more closely than it should.

Electronic Stability Control (ESC) may respond improperly while working in conjunction with the incorrectly calibrated ABS module. This can lead to several problems, including ESC activating in an understeer condition without switching on the brake lights to warn other drivers, or ESC delaying activation when oversteer occurs, potentially increasing the chance of oversteer.

The fix: dealers will recalibrate the ABS module so that the ESC system operates using the correct 200-inch or 212-inch wheelbase measurement, causing the vehicle to function properly.

Only Chevrolet Medium Truck dealerships are able to carry out the recalibration correctly. No parts are required for the repair, which can be completed in an average time of 36 minutes.

Affected components: 

Antilock Brake System (ABS) control module.

Affected vehicles: 

• 2022 Chevy LCF 5500 HD/XD with a 200-inch or 212-inch wheelbase
• 2023 Chevy LCF 5500 HD/XD with a 200-inch or 212-inch wheelbase

Number of affected vehicles: GM did not specify how many vehicles are affected by this condition.

Additionally, all affected 2022 and 2023 Chevy LCF 5500 HD/XD trucks are under a stop delivery starting on January 23^rd, 2023. Dealerships with these trucks in stock should not demonstrate them, deliver them to customers, or dealer traded until the specified repair has been completed.
