The worst model year for it is 2018.
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.
NHTSA complaint #11763921 — an unverified report by a vehicle owner.
I am reporting a transmission safety problem with my 2016 Ram 2500 Cummins that began shortly after FCA campaign U29 was performed. Before the recall work, the transmission and original solenoid were functioning normally. I had no transmission symptoms, warning lights, or transmission codes. The dealership performed U29 and replaced the transmission solenoid May 4-6, 2026. I picked the truck up May 6 at 149,091 miles. About 79 miles later, the check-engine light came on and transmission problems began. While driving, including on the interstate, the truck would suddenly jerk, the RPMs would rise quickly, and the truck would lose speed. On several occasions, traffic behind me had to react quickly to avoid hitting me. The dealership told me the solenoid installed during the U29 repair was defective and replaced it with another solenoid. The same problems continued. The truck later developed code P0871, became undriveable, and was towed back June 1. The original transmission ultimately failed. The dealership then installed a Mopar remanufactured transmission. I picked it up June 13. Within roughly 600 miles, it developed substantially identical symptoms and failure patterns, including P0870 and P0871, limp mode, and another major transmission failure. It was towed back June 24. The dealership later found the overdrive clutch had disintegrated and metal was present in the transmission fluid. The failed remanufactured transmission is now being handled under its Mopar warranty, and the dealership is looking to install a third transmission without identifying a clear reason for the repeated failures. I am concerned the same problem could happen again and believe the U29 repair, replacement parts, or another related transmission problem should be investigated.

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.

I pulled over into a parking lot and shut off engine. Vehicle continued to make screeching sound from engine bay; I opened hood to a billowing smoke that smelled like an electrical fire. Noise and significant smoke continued for several minutes with engine off and ignition in off position.
NHTSA complaint #11757982 — an unverified report by a vehicle owner.
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.

NHTSA complaint #11755850 — an unverified report by a vehicle owner.
I own a 2018 Ram 2500 4x4 diesel, VIN [XXX], affected by FCA/Stellantis Safety Recall C4B / NHTSA 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. NHTSA'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 NHTSA to review this situation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I received the ABS recall letter in 2024 and periodically since. I have contacted RAM after 2 years with no remedy and because I complained they have since blocked me. This is an unacceptable safety issue they should be addressing but are not. Please help. My truck only has a little over 100k miles on it. I deserve help with this EXPENSIVE purchase as I bought it new!

Service electronic braking systems is on as well I been almost had accidents and loosing control with my trailer that I don’t feel safe anymore for me and my passengers.

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 NHTSA and the manufacturer with questions and asked for a timeframe for a fix and have received nothing.
NHTSA complaint #11753324 — an unverified report by a vehicle owner.
Stellantis issued a STAR service order regarding the digital rearview mirror not operating. I bought my truck in April of 2026 and the mirror was inoperable. Ram dealers have had the truck in the shop for over 10 weeks and cannot fix this safety issue. A STAR number and two claims numbers have been assigned. Stellantis Customer Service cannot understand what is being said and no rental car afforded. In essence, they cannot fix this problem. It must be forced for Stellantis to fix this wide spread problem.

My 2018 dodge ram has an open recall since December 2024. There are no parts/no fix. My truck has been dinging and pinging with the break light/traction light/engine light/ABS light since 6 months after I got it. ALL of these things are related to the open recall. VIN [XXX]. Manufacturer Recall Number C4B, NHTSA Recall Number24V-896. "The loss of ABS/ESC/Traction control may cause a vehicle crash without prior warning." On Sunday the 19th it stalled along with the warning lights. I took my truck to the dealer and paid $198 in Feb 2023 and they told me nothing was wrong with it. This issues would happen every so often now it's happening frequently almost daily. Customer care refuses to help. They told me to take my truck to a dealer to get it diagnosed and then send the paperwork to them and maybe they'd cover the rental until the part comes in. So now I am paying another $255 for Another diagnostics. It's sitting at Dodge in Glendora, CA right now for 2 days waiting for a call back. I was also told if it's approved, I have to pay for the rental out of pocket. For an eternity? I am not sure why I am jumping through hoops for a safety recall. It' the only car I have to commute and drive my kids in. Once again, a safety recall. This is really absurd. I begged for a manager or someone higher to call me and Ram care refused. Said they'd send my case to rentals. What if my breaks go out, what if I get in a car accident. It feels really unreasonable they won't take responsibility for this ongoing open recall that is a safety issue.

NHTSA complaint #11750664 — an unverified report by a vehicle owner.
To Whom It May Concern, I am requesting a no-cost replacement of the factory Uconnect 8.4 radio in my truck (VIN: [XXX]) due to daily safety-related failures that significantly affect the safe operation of my vehicle. Every day, the radio experiences a startup delay where the screen remains black and many center stack functions are unavailable. This delay often lasts 5–10 minutes before the system becomes operational. During normal driving, the radio also displays repeated “Vehicle Phone Requires Service” error messages, creating a constant distraction that takes my attention away from the road. When these issues occur, the factory backup camera is unavailable. Losing the backup camera eliminates an important safety feature intended to help prevent collisions with pedestrians, children, vehicles, and objects while reversing. Additionally, the factory navigation and GPS no longer function at all. These are not minor convenience issues—they are daily safety concerns. Safety-related features should work immediately every time the vehicle is started. A factory infotainment system that fails every day, disables the backup camera during startup, and repeatedly distracts the driver while the vehicle is in motion presents an unacceptable safety risk. Because these failures occur daily and involve factory-installed safety equipment, I believe Stellantis should replace the defective Uconnect radio at no cost. I respectfully request that this complaint be documented and that a no-cost replacement be authorized. Thank you for your prompt attention to this matter.
