MANUFACTURER VIOLATION OF FEDERAL TREAD ACT REIMBURSEMENT REQUIREMENTS Vehicle experienced ABS hydraulic control unit failure in September 2022 with warning lights and transmission shifting problems. Repairs cost $5651 addressing brake system hydraulic control unit defects. In November 2024, manufacturer issued Recall C7B/NHTSA 24E-100 for identical hydraulic control unit ABS defects affecting 2012-2018 Ram vehicles. Federal regulation 49 CFR 573.13 requires manufacturers reimburse pre-notification repairs reasonably necessary to correct recalled defects. Manufacturer FCA US LLC improperly denied reimbursement under case 92237530, claiming parts not covered under recall repair. This violates federal TREAD Act mandatory reimbursement requirements. …
While driving down highway 65 mph, abs system activated causing right rear brakes to activate causing vehicle to activate steering control making truck head towards on coming traffic before able to control vehicle to shoulder of roadway. Would like to know if, when, and who and where any previous recall work has been performed to this vehicle, bought at a dealership in Oklahoma with check engine light on, told it was gas cap. Turns out it was not a gas cap, there was programming involved to remove the MIL function of brake system. ECM was sent to a 3rd party vendor and unlocked, afterwards the previous program was unlocked showing disabling of MIL functions for several functions. Vehicle is having issues with electrical radiator fan causing excessive heat in compartment, what was the fix for this by MFG? Was it to just program out the electric fan from coming on at high speed ? …
After parking right after a paid car wash, the truck wouldn't start and had no power to any component. Couldn't get vehicle out of park. Batteries fully charged and no issue with terminals. There would be random moments when power came back but when starter was pressed, a clicking sound would occur and all power shut down again. Truck had to be towed to dealership where they were unable to duplicate or determine what caused the problem. Our concern is not being able to move the vehicle out of danger when this occurs or the danger of it occurring while in motion, which we experienced years ago with a Jeep Grand Cherokee.
The blower motor for my air conditioner and heater is not working properly. The service company told me this is an ongoing issue with this model truck and I should file a complaint due to the number of incidents They are having with this vehicle with this problem. The service technician stated the computer box was full of corrosion from not being sealed properly from the factory. The service technician also stated that if the corrosion continues and the issue is not corrected, it could affect the entire ECM of my truck and my truck will not start.
