SERVICE BRAKES
My 2018 Ram 2500 has a continuous ABS/ESC/Traction Control failure related to recall C4B (NHTSA 24V‑896). The hydraulic control unit (HCU) is failing exactly as described in the recall. The ABS light, traction control light, and stability control warnings come on constantly, and the cruise control shuts off while driving. This is a safety‑critical defect that increases the risk of a crash, as NHTSA states in campaign 24V‑896. My dealer confirmed the recall but says the remedy parts are unavailable and may take months. I am driving a vehicle with disabled ABS and stability control because Stellantis cannot supply the required HCU replacement. I am requesting NHTSA assistance because the manufacturer cannot provide a timely safety repair. I also have a bad knee and can NOT drive without cruise control.

My 2018 Ram 2500 has a safety recall (C4B/NHTSA 24V - 896) for BRAKES AND TRACTION CONTROL and the remedy for this condition is "NOT CURRENTLY AVAILABLE" ??? I have contacted FCA recall assistance center and 2 different dealers and they all are "SORRY" but say there is nothing they can or will do. One dealer offered to replace the defective part with another defective part if I was willing to pay for it and said that it would probably fail again. How can the US Dept. of Transportation allow a "US auto manufacturer" to sell a defective heavy duty vehicle used to transport loved ones and haul heavy loads with DEFECTIVE BRAKES? To add insult to injury Rams new promotional add states "Nothing Stops Ram" (True statement - Not even the BRAKES)... I'm happy to report there has not been a serious accident to date but the driver and passengers do not feel safe when the bells go off and warning messages appear on the dashboard... Thanks.

I have the active recall associated with the vehicle listed. It’s been nearly 2 years with the active abs service light, traction control light, and inoperative cruise control due to those lights. Stelantis is not very helpful. Will not fixit yet. But says I can pay myself and some or all may be reimbursed. There is no reason it should take this long. Endangering lives potentially. I sent truck pulling all the time. And you buy these things with these safety options that should work. To be taking this long to remedy this. Is unacceptable

SERVICE BRAKES
I am filing a formal complaint regarding m y 2018 Ram 2500 which is subject to safety recall 24V-896 for a defective anti-lock brake system module and hydraulic control unit. This critical safety recall was issued in November 2024 and as of today 8/29/2026 it has been nearly two years, and the manufacturer (Stellantis/FCA) has failed to provide a remedy. My vehicle currently displays warning lights for the ABS, Electronic Stability Control and Traction Control Systems indicating that these vital safety features are entirely disabled. Driving a heavy-duty truck without functioning ABS or stability control poses an immediate safety hazard to myself, my passengers, and others on the road, especially when towing or diving in inclement weather. Because the manufacturer has failed to provide a remedy within a reasonable timeframe, I am requesting that the NHTSA intervene to compel Stellantis to expedite parts distribution or provide immediate alternative transportation (loner/rental vehicle) at their expense until my vehicle is repaired.

There is an active recall on my vehicle related to anti-lock brake system with no remediation plan at the moment due to a part shortage. My vehicle is displaying anti-lock brake service warnings several times during drives which ultimately go away. I'm being told that the warnings are tied to the recall. How can I get the issue remediated without any support from the recall? This seems very dangerous to have customers with impacted vehicles but no support to remediate the issue.

I have been waiting on the C4B recall for nearly two years with no parts available still. My truck has no ABS, traction control, or 4WD. This is a 2500 heavy duty truck meant for pulling trailers and heavy payloads. This recall has rendered the vehicle useless. I can't trade it in due to the ongoing recall, it is not safe to drive, I am at an extreme financial loss due to Stellantis' negligence. How has the US government allowed this issue to last for so long? How many unsafe vehicles are currently driving down the road with compromised brakes?

ABS system failure. This is due to recall # 24v-896. This recall has been active for nearly 2 years and it appears the manufacturer has no intent on ever developing the parts to repair the issue. However the manufacturer states that customers can have the repair completed on their own at authorized dealership and possibly be reimbursed. So if customers can opt to pay out of pocket for the repair the parts must be available. So it seems the manufacturer is just trying to avoid paying the cost of this safety issue repair.

I haven’t experienced an issue yet. A safety recall was finally issued to my 2018 Ram 2500 pickup truck in 2024. I had taken it to the local Ram dealership (Rairdon’s Ram, Bellingham, WA). On two separate occasions for my truck throwing the following warning light, “Check Electronic Braking System”. At the same time, traction control is deactivated, and cruiser control turns off, so if you have cruise control set, the warning light causes the cruise control to deactivate, and the truck immediately starts to slow down. This is a problem at highway speeds. The warning light also activates a chime that pings incessantly for several minutes and will continue to sound every 30 minutes while driving. Ram finally identified it as a safety issue, and issued a recall. However they stipulated there was no fix identified yet. It has been going on two years since being notified, and I have checked with my local dealership, and no fix has been identified still. My complaint is that Ram is dragging its feet with this recall repair.

The RAM Dealer (Aventura) has been telling me for over a year that the parts are on back-order.

The Hydro Boost Pump Port Tube Assembly (Mopar P/N 04581758AA / 4581758AA) on my 2018 Ram 2500 6.7L Cummins has failed and requires replacement. My concern is that this component is part of the hydraulic assist system supporting critical steering/braking functions. A failure or loss of hydraulic pressure could result in significantly increased steering or braking effort and create a serious safety hazard, particularly while towing, carrying a load, or traveling at highway speeds. I am requesting NHTSA review this component and determine whether similar failures have been reported on Ram 2500 vehicles and whether further investigation or manufacturer action is warranted.

My 2018 2500 Ram trucks ABS warning light "ABS system needs maintenance" is activating intermittently. I took the truck for maintenance and was told that there is a recall on the defective part (Recall C4B) since end of 2024, with the only remedy being to replace this defective part failure with the same defective part, installed at my cost of between $1200 to $2500. Twenty months into this recall, I have 4 alternatives: 1. Pay to have a defective part installed which will eventually fail again. 2. Drive the truck taking a chance that the recalled part or newly installed recalled part will not fail, OR crash because the part has a complete failure (without notice) and have no brakes when needed to stop my vehicle. 3. Park my truck and not drive it. 4. Spend tens of thousands of dollars by either trading it in or selling it and purchasing a vehicle which is safe to drive. All of the above choices except #2 create a financial hardship in one way or another and choice #2 could be life ending for me and whomever I hit when I have no brakes without notice. Please help me understand how this dangerous and potentially life-threatening recall has not been escalated by the NHTSA to FCA as a high-priority emergency in the last 20 months to get a timely remedy from FCA and to start repairing this dangerous situation. This is America, we are better than this. FCA needs to be held accountable by the NHTSA to protect the consumer from these non-compliant manufacturers.
