2018 Ram 2500 electrical problems

Filed Oct 7, 2026 · Brakes, Electrical · IN

The truck is under recall C4b for the ABS / Traction control system, which also disables the cruise control. I have called several times and had the vehicle into local dealerships and was told there is still no fix. I asked about trading in the truck and the dealers offered me way below KBB value stating they don't want the truck because of the recall. I ask Ram to help me out and they said there is nothing they can do. 3 times now in over the almost 2 years this truck has been under recall C4B the truck has only engaged the rear brakes during a panic stop causing me to almost crash. I talked with Ram recall department and that told me to stop driving the truck, I told them it was my only transportation. They then told me it's up to a dealership if they want to give me a rental until the fix becomes available, of course the dealers do not. I am frustrated and at wits end, the truck constantly dings at me turning the ABS light on and off all day everyday. I have had no use of my cruise control for almost 2 years, and can not pull trailers like I intended to do with the truck becuase the companies will not pass the truck in their inspections because of the ABS / Traction control lights being on. The lights have been coming on since about December of 2024, and stayed on since Febuary of 2025.

Odometer Fraud. The contact intended to purchase a 2018 Ram 2500. The contact discovered that there was a mileage discrepancy. The vehicle was a private sale. The advertised mileage was 130,200; however, a Carfax report displayed a mileage rollback, and the ECU listed the mileage at 200,220.

The contact owns a 2018 Ram 2500. The contact stated that after his daughter started the vehicle, there were dings and bells sounding for approximately 4 to 5 miles. The “Service Electronic Braking System” message was displayed and the cruise control was inoperable. The contact referenced the federal safety agency Campaign Number: 24V896000 (Service Brakes, Hydraulic). The dealer informed the contact that parts were available, but the dealer declined to repair the vehicle. The contact called two other dealers, South Richmond Chrysler Jeep Dodge Ram - Parts Department · South Richmond Chrysler Jeep Dodge Ram - Service Department (4510 Whitehill Blvd, Prince George, VA 23875), and Whitten Brothers Chrysler Dodge Jeep Ram Parts Store · Whitten Brothers of Richmond Service Center (10701 Midlothian Turnpike, Richmond, VA 23235). The vehicle had been inspected at the Virginia state inspection station. The failure mileage was 70,000.

My 2018 Ram 2500 is subject to safety recall C4B/24V‑896 involving failure of the brake Hydraulic Control Unit (HCU) and possible loss of ABS, electronic stability control and traction control. I previously contacted a Ram dealer in [XXX] regarding completion of this recall but was informed that the parts/remedy were not available. The recall therefore remained unrepaired. On XXX, my vehicle was sideswiped by another vehicle. The other vehicle caused the initial collision. Immediately before, during, and following the sideswipe, I applied the brakes to stop my Ram. During the emergency braking event, the wheels locked and I did not experience normal anti-lock braking operation. I was able to bring the vehicle to a stop without subsequently striking another vehicle or object. Following the incident, the ABS and traction-control warning lights have remained continuously illuminated and have not returned to normal operation. I am concerned that the recalled HCU may have failed and that the ABS/ESC/traction-control systems were unavailable during the emergency braking event. This incident involved actual wheel lockup during emergency braking associated with a collision, followed by permanent ABS/traction-control warnings on a vehicle with an unrepaired safety recall addressing loss of those same systems. I am reporting this incident so the federal safety agency has a record of the apparent safety-system failure and the fact that I had previously attempted to have the recall addressed but the remedy/parts were unavailable. The vehicle is being preserved for diagnostic evaluation. I am requesting that all relevant ABS/HCU diagnostic trouble codes be documented before they are cleared or repairs are performed.

My 2018 Ram 2500 has a continuous ABS/ESC/Traction Control failure related to recall C4B (the federal safety agency 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 the federal safety agency 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 the federal safety agency assistance because the manufacturer cannot provide a timely safety repair. I also have a bad knee and can NOT drive without cruise control.

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.

My vehicle has had an open recall for almost 2 years. The ABS light and alarm keeps going off and when I was pulling my camper, the camper was pushing the truck while trying to stop the truck.

My family and I tow a 45 foot RV Toy Howler Fifth Wheel with the truck and the ABS and Traction control lights keep coming on. The RAM Dealer (Aventura) has been telling me for over a year that the parts are on back-order. I've tried to trade it in but the trade in offers have been very low since they know there's no repair parts. I'm very concerned about our safety since we take long trips into the mountains and this is constantly going on.

This truck has been built with a brake hydraulic control unit ("HCU") that is susceptible to failure or malfunction which may result in a reduction or change of Anti-Lock Brake System ("ABS")/Electronic Stability Control ("ESC") /Traction Control performance. A failing HCU will initially result in the intermittent loss of ABS/Traction control progressing to permanent loss. Safety Risk The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning.

I own a 2018 Ram 2500 4x4 diesel, VIN [XXX], affected by FCA/Stellantis Safety Recall C4B / the federal safety agency 24V‑896 involving the ABS Hydraulic Control Unit (HCU). My truck is now experiencing the problem. The ABS warning light comes on and the cruise control becomes unavailable. The vehicle and component are available for inspection upon request. I am concerned about safety because this malfunction affects the ABS system and could affect braking performance, particularly during emergency braking or on wet or slippery roads. I contacted my Ram dealer the week of June 15, 2026. I was told this was a recall issue and that although the permanent remedy was not available, Chrysler was allowing dealers to replace the part with the existing-style part at Chrysler's expense. I was told a part would be ordered and I would be contacted, but I never heard back. I contacted the dealer again the week of July 13. They could not find the previous order but again told me they would order the part and that it would be covered. I received no follow-up. On July 27, I called again and was told Chrysler/Stellantis was no longer paying for this replacement and I would have to pay for the repair myself. the federal safety agency's VIN lookup currently shows the C4B recall on my truck as "Remedy Not Yet Available." To my knowledge, the truck has not been physically inspected by Stellantis or an independent shop for this complaint. My concern is that Stellantis acknowledges a safety defect in the ABS system, my truck is experiencing the malfunction, yet no permanent remedy is available and I am being told I must pay for an interim repair myself. I am asking the federal safety agency to review this situation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
