New Safety Recall Advanced Communication – ZA5

FCA US LLC (FCA US) has announced a safety recall on certain 2019 and 2020 Model Year (DP) Ram 4500/5500 Cab Chassis vehicles.

 

REASON FOR THIS SAFETY RECALL

Some of the above vehicles may have a rear brake hose with an out of specification orifice diameter. A brake hose that does not meet constriction requirements may be more susceptible to hose assembly rupture. A ruptured brake hose could result in reduced braking performance, which may increase the risk of a crash without prior warning.

The condition described above does not comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 106 S5.3.1 Constriction requirement states, “Except for that part of an end fitting which does not contain hose, every inside diameter of any section of a hydraulic brake hose assembly shall be not less than 64 percent of the nominal inside diameter of the brake hose.” Brake hoses that have an out of specification orifice diameter have an inside diameter that is less than the 64 percent requirement.

 

SERVICE ACTION

FCA US will conduct a voluntary safety recall to replace the rear brake hoses. The remedy for this condition is not currently available. Dealers will be notified of the launch of this safety recall by way of established communication methods. This recall is estimated to launch in 4th Quarter of 2022.

 


Chronology :

  • On August 28, 2020, the FCA US LLC (“FCA US”) Vehicle Safety and Regulatory Compliance (“VSRC”) organization opened an investigation based on information from the FCA US Chassis Engineering group of a potential noncompliance for the rear brake hose assembly on 2019 and 2020 MY Ram 4500/5500 cab chassis vehicles.

 

  • On September 23, 2020, the FCA US VSRC organization confirmed that rear brake hose assemblies may have been built with an orifice diameter that is out of specification.

 

  • On October 15, 2020, FCA US determined, through the Vehicle Regulations Committee, to conduct a voluntary safety recall of the affected vehicles.

 

  • On October 22, 2020, FCA US filed a Noncompliance Information Report pursuant to 49 CFR Part 573 which was assigned NHTSA recall number 20V-649 and FCA US Recall Number W75.

 

  • On November 13, 2020, FCA US petitioned the NHTSA, pursuant to 49 CFR Part 556, for exemption from the notification and remedy requirements.

 

  • On October 5, 2022, FCA US received notice that the NHTSA denied FCA US’ petition.
