2018 Ram 2500 acceleration problems

Filed Sep 18, 2026 · Acceleration, Brakes · IN

This recall has been in effect for almost two years. I have been affected for the past year with almost constant warning alarms distracting my attention to drive. The Chrysler Mechanic did diagnose that my ABS system has failed but t hat a remedy was, and still is not available. In the meantime I rarely my 2500 RAM Diesel because I have no ABS, cruise control or the ability to disable the traction control. The mechanic was not able to turn the alarm off and turning up the radio is not a safe option either. I drive many highway miles and often transport my Grandchildren to and fro. The latter is the reason I bought a heavy duty vehicle for safety. Due to the weight of my truck, without cruise control it is challenging to maintain consistent speeds on the highways and I am a nuisance to most drivers which has caused more than one bad reaction from other drivers. Not to mention the loss of 3 to 4 MPG of diesel. Recently my second vehicle is getting repairs and I am having to use my RAM exclusively. The recall center agreed that I have safety issues with my vehicle and offered me a rental, but after providing the requested information downloaded from the truck by the certified mechanic, I was told that more information was needed. This took place over a period of approximately two weeks where I surrendered my truck to their unsecured lot. At that time I retrieved my truck and concluded that this was a cat and mouse chase. So now I am once again driving my unsafe truck looking at navigating Indiana winter roads. Over six months ago I was the assured that the replacement part was in the final stages of testing and this is the same story today.

The contact owns a 2018 Ram 2500. The contact stated that while driving at various speeds with cruise control engaged, there was an abnormal dinging sound coming from the vehicle, and the cruise control disengaged. The vehicle started coasting. The driver reset the cruise control. The ABS message was displayed. The contact received notification of the federal safety agency Campaign Number: 24V896000 (Service Brakes, Hydraulic). The failure recurred while on the interstate, on country roads, or pulling out of the driveway. The contact was concerned about losing the vehicle, which was taken to the local dealer, who was unable to repair the vehicle because parts were not available. The vehicle was taken to another dealer Dan Cummins Chevrolet Buick of Paris Service Center (1020 M.L.K. Jr Blvd, Paris, KY 40361), but it was confirmed that the part was not available for the recall repair. The customer service for the manufacturer was contacted, and the contact was advised to drive carefully because the recall failure posed a crash safety risk. The failure mileage was unknown.

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

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, Traction Control warning lights on dash and loss of cruise control function causing sudden deceleration on highway. The dash warning includes incessant dinging. This manufacturer has been NEGLIGENT AND INCOMPETENT in providing resolution.

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 the federal safety agency review this component and determine whether similar failures have been reported on Ram 2500 vehicles and whether further investigation or manufacturer action is warranted.

ABS, Traction controle and 4 wheel drive system shut down. the truck is sending code- C0031-1D directly related to C4B recall. The dealerships have no fix and offered no support or guidance but did agree that the truck is unsafe to drive as is.

The electronic throttle control light and check engine light are on. I took it to a mechanic and had the accelerator pedal replaced. The lights remained on and the truck remains in "limp mode" and will not go over 59mph. The mechanic stated that this is due to the unresolved recall problems with the traction control and anti lock braking system, and the HCU needing replaced. These components and labor are over 2-3 thousand dollars! I have called the federal safety agency and the manufacturer with questions and asked for a timeframe for a fix and have received nothing.

The recall causes the cruise control to be inoperable, the abs system to be inoperable and causes the warning messages to flash and the audible tone to sound constantly. I am currently unable to utilize the vehicle as intended (towing) because of the braking safety issue.

ABS failure. Dealers keep stating there are no replacement parts available. Also loss of cruise control. Ram is stalling for time. Time to force the issue. They can get the parts made!
