2018 RAM 3500 Complaints

The Automatic Braking System (ABS) and Traction Control lights come on intermittently. They flash and and sound at random. A RAM dealer stated the lights must be on for them to get a proper code to determine the problem. This is an extreme safety problem that could occur at anytime ABS and traction control may be needed.

My Hydraulic Control Unit for my ABS has failed this is the second time in 24 months it has failed and needing service. The part is on backorder and it seems to be a major known issue by the manufacturer with repairs costing near 2k dollars to the consumer because Ram does not want to cover it under warranty.

ABS Pump motor control - General electrical failure that causes the warning lights on the dash to illuminate and an audible chime. Occurring sometimes several times in a row, which distracts operator from safe operation of the vehicle with flashing dash warning lights and audible chimes, affecting in the operation of ABS SYSTEM if required for safe emergency stopping in an emergency situation. Yes the problem has been diagnosed by a dealer ECU: ABS, CODE: C0020-01, DESC: ABS Pump Motor Control- General Electrical Failure The Manufacturer has and is aware of the batch of failed components as per various website forums. And dealer says the components for repair are unavailable for sometime. Uncertain exactly when warning lights started to flash generally, October 2022

ABS and Traction control lights on. ABS Code C0020-01 ABS pump motor general electrical failure. See you recently posted some information regarding 2017-18 Ram 2500 -3500 trucks. Lots of complaints on Ram Truck forums. Lots of problems with HCU and ABS Contollers. SHOULD BE A RECALL. No braking problems...(yet)

Eight months ago I got a "Service Electronic Braking System" warning in the Instrument Cluster. After a brief Google search it was evident that this was a common issue on these RAM trucks. After some diagnostics I determined the ABS Module and/or the HCU to be faulty. After 3 months of calling Ram dealerships in nearly every state I was finally able to locate a new ABS Module, but the HCU has been on backorder country wide for over a year now. I was recently advised by a RAM dealer that the sale of new HCU has been halted until Feb 2024 while RAM performs an internal investigation into the cause of the faulty units. The ABS, Cruise Control and Traction Control features are disabled while this fault remains. While the main vehicle brakes still function properly, the lack of ABS and Traction Control can pose a risk while driving in lower friction environments (i.e. snow, ice, rain, etc), or while hauling a trailer. RAM is not covering these parts under warranty nor is there has any type of safety recall been issued by RAM. The consumers are having to come out of pocket for these repairs (when the parts are available).

C0020-01 ABS Pump Motor Control - General Electrical Failure Under Warranty by FCA Extended Warranty Unable to order part until after 2/21/24 Unsafe to drive with issue and cruise control is inoperable Dash continues to beep while driving which is also very distracting

While driving in heavy rain a car in front of me slammed on their brakes, in response I applied mine. Instead of the ABS engaging, the rear wheels locked up and started to slide, which caused the truck to start to slide sideways on the rain slick road. Fortunately, I had maintained sufficent distance between myself and the car in front of me and there was no accident. Also fortunate was the fact no other cars were around me when the vehicle started to skid. Once I got stopped I noticed the ABS and Traction Control lights were now illuminated on the dashboard. Later that day I had the codes downloaded and received a C0020 code. Which indicated an issue with the HCU and ABS. After reviewing this issue online, I discovered that this is a know issue to FCA and the NHTSA and that many complaints have been reported concerning this issues, including a document from FCA (Star Online Publication: Case #: S2005000004) which is also on the NHTSA own website. There is no system on a vehicle more important than the braking system! Knowing the number of occurrences of this issue and possible severity of injury or even death that could result from this issue, why has the NHTSA not issued a recall for the vehicles? The NHTSA knows of this issue as evidenced by the STAR publications (now at revision C) posted on your website! Please do what your agency was chartered to do, hold the manufacturer of these vehicles accountable for fixing an obvious safety issue! I was lucky, I was not injured, neither was anyone else, but other people may not be as fortunate. Thank you,

ABS System flashes on and off that it needs to be serviced, also cruis control doesn’t work. Took it to dealer to get it diagnosed. Dealer says the HCU needs to be replaced and the ABS pump needs to be replaced and also that cause the brakes and rotors to wear out and they need to be replaced too.

ABS/Electrical Break Control fault code C002001, a known issue with the 2018 Ram 3500, occurred at 26,000 miles rendering cruise control, traction control, and trailer brake controller inoperable. Repair parts are unavailable currently and is not covered under warranty due to age of vehicle.
