Ram HD produced between 2017 and 2018 are investigated for having problems with the brake system

The National Highway Traffic Safety Administration received 134 consumer reports alleging intermittent or permanent loss of braking performance on certain Ram 2500 and 3500 pickup trucks from 2017 to 2018.

The Defect Investigation Office has opened an investigation into the matter, which could end with the recall of 390,077 trucks.

"The alleged failures continue to occur at a steady pace in both models, at all speeds, with limited detectability," notes the Office of Defect Investigation.

Several reports indicate that replacing the anti-lock brake system module and hydraulic control unit appears to correct this problem.

ABS can trace its roots back to 1908 when JE Francis introduced the so-called Regular Slip Prevention for Rail Vehicles.

In 1920, Gabriel Voisin designed a system that modulated brake pressure to reduce tire slip.

The automotive industry's first series-production ABS is credited to Mercedes-Benz, who introduced a system developed by Bosch in August 1978 on the W116 Sonderklasse generation as an optional extra.

HCU, on the other hand, refers to the hydraulic control unit. Simply put, it is an electromechanical device that controls hydraulic pressure to individual wheel brake assemblies.

The HCU is designed to manage braking forces during hard stops, making driving much easier.

Turning our attention to investigation number PE 22-012, the ODI does not mention which 2017-2018 Ram 2500 and 3500 configurations are potentially affected.

To whom it may concern, the 2017 model welcomed the Power Wagon and the 2500 4×4 Off-Road package to the roster.

The biggest updates for 2018 came in the form of the Limited Tungsten and Sport editions, as well as 8.4-inch touchscreen infotainment with 4G LTE, HD Radio, USB Flip, pinch-to-zoom, Android Auto and Apple CarPlay.

Maximum trailer and payload ratings are shared between the 2017 and 2018 model years.

More specifically, the 3500 holds up to 31,210 pounds (nearly 14,157 kg) and 7,390 pounds (3,352 kg).
