2018 Ram 1500: adaptive cruise control problems

Filed Oct 12, 2026 · Brakes, Steering · TX

San Antonio Tx was driving this morning in a light mist had my son in the truck the vehicle ahead of me came to an abrupt stop and I had to hit my brakes pretty hard and without the abs working properly I am impacted by the ABS controller failure However, I was surprise at how few have files formal NTHSA complaints on a serious issue that appears to impact thousands of trucks prior to 2019. The only way to move this ball forward and get injunctive relief is to inform NTHSA. To Whom It May Concern at the federal safety agency, I am filing this safety complaint regarding a defective ABS Hydraulic Control Unit (HCU) on my 2018 Ram 1500 TRADESMAN CREW CAB 4x4 5.7L Hemi with approximately 200,000 miles. DEFECT DESCRIPTION: The ABS HCU has failed, resulting in complete loss of anti-lock braking, traction control, electronic stability control, 4WD and cruise control. This is an identical failure mode to the defect addressed under the federal safety agency Recall 24V‑896, which covered 2017-2018 Ram 2500-5500 trucks. My 2017 Ram 1500 uses the same or substantially similar HCU component and is experiencing the identical failure. SAFETY RISK: The loss of ABS, ESC, 4WD and traction control significantly increases the risk of a crash, particularly in adverse weather conditions. This is not a minor inconvenience — it is a serious safety hazard that FCA/Stellantishas already acknowledged in heavier-duty Ram platforms. MANUFACTURER KNOWLEDGE: FCA was aware of this defect as early as 2016 based on warranty claims and customer complaints. Despite issuing Recall 24V‑896 for heavier Ram trucks with the same HCU failure, FCA has failed to extend recall coverage to the 2018 Ram 1500, leaving thousands of owners without remedy. FINANCIAL IMPACT: Repair estimates range from $1,200 to $2,000. The part remains on backorder or engineering hold, making timely repair impossible through normal channels. REQUESTED ACTION: I respectfully request that the federal safety agency: 1. Open a formal investigation into the 2017 Ram 1500 ABS H

As we were driving along the freeway at highway speeds, the dash lights completely cut out on my ram 1500 2019. At first, this seemed to simply affect the visibility of the central console, speed controls, light indicators, etc. But then as we continued on and proceeded to exit the freeway, the entire vehicle shut down and lost total power steering speed control and power braking. I had to rapidly exit and take at safety on side of the road before completely losing control. Previously we had lost power to the video control display but it had never lost power before. We had also previously experienced where we were on the freeway at freeway speeds and the cruise control just rapidly shut down the same time as the video console shut down and the vehicle proceeded to slow rapidly and unexpectedly. After the incidence of losing cruise control and losing the central display, we took the vehicle multiple times to a ram authorized dealer service center in salt lake City as well as an independent shop. Neither could replicate and the issue as it is severely intermittent. We continued to use the vehicle given their clean bill of health. However, this incident showed a new level of severe risk in driving the vehicle. There were no warning indicators or flashing lights as the console completely failed in the middle of the driver screen. By several mechanical shops unable to replicate the issue. We were able to start recording upon the demonstration of the latest incident and have a video of this happening but too large to upload. Should this have happened while we were still on the freeway and unable to safely navigate to a shoulder on either the left or right of the road, we would have essentially been forced to go from full-freeway speeds in a matter of seconds, creating a significant risk for ourselves and others. You can see in the video the central console goes completely black does not show speed Indicators does not flash any warning signal, intermittent control.

I have a 2018 RAM 1500 Tradesman 2WD truck that the the ABS warning ligh as well as check engine, brakes warning light keeps staying on. I am very concerned about this as it may cause me to NOT be able to brake in time to. Also the cruise control does not work. I've taken it to several different mechanics as well as Autozone and I'm told the error code is C2200-49 which is the Anti-lock Brake Module Internal- Internal Electronic Failure. My mechanic has told me there is NO PART available and has been on back order for the past year. My only recourse is to locate one from a junk yard and hope that it will work. I've done an exhaustive on-line search and haven't been able to locate the module for my year and model truck through any RAM 'MOPAR' dealership. I've been on several different message boards and have been told there are thousands of trucks out there with this issues. Please, help us by making RAM do a recall on this vehicle.

ABS light and traction control lights on, on dash. With these lights on, the cruise control and 4x4 do not work. One garage replaced front right axle, wheel bearing, brake rotor, brake pads, and ABS sensor. Lights were then out for a day but then came back. Took to a second garage and they replaced right rear ABS sensor. Lights went out for another day and then came back. They are still on. Because of Christmas it's been hard to get anyone to look at it. Also they say this is a known problem without any definite solution.

I am writing to your Company regarding the unavailability of the ABS Control Module for 2017 Ram 1500 trucks. My truck, like those of numerous other Ram owners, has a malfunctioning ABS Control Module. Because of this malfunction, the ABS and cruise control do not work. In turn, this places me and other owners of this vehicle in an unsafe situation, in that the lack of an operating ABS system is conducive to skidding and accidents. Some owners have even reported that they cannot drive their vehicles due to locked brakes resulting from this malfunction. I have tried every source in existence in my efforts to find a replacement module, but I have been totally unsuccessful. I have been told by one of your Customer Service representatives that your Company is “…unable to maintain a complete inventory for an indefinite period and the lower the demand, the less likely it is we will have stocked parts. As such, the part you are requesting is no longer in our inventory.” I am aware of a current class action suit against your company for the RAM 2500 & 3500 for the same issue. I guess the owners’ lives of the Ram 1500 are not as important. Wilson, et al. v. FCA US LLC Case No. 4:22-cv-0044 This is absolutely appalling. Apparently, several thousand Ram owners who paid tens of thousands of dollars for their trucks are not important enough to your Company to warrant providing the necessary support for their products. I am thoroughly disgusted with the disrespect and value you place on the safety and lives of your truck owners and the other drivers on the road who are in danger due to the lack of support or concern you have for your “valued? owners”.

The abs keeps randomly disabling and then coming back on. When this happens, the cruise control is canceled which causes a sudden change in speed unexpectedly. Also, the 4x4 gets disabled. I believe the issue is this: hydraulic control unit can malfunction, impacting ABS, electronic stability control, and traction control performance software issue in the Anti-lock Brake System (ABS) control module that can disable the Electronic Stability Control (ESC) system, potentially increasing the risk of a crash.Â

The electronic trailer brake system, anti-lock braking system, and electronics traction control system lights activate upon driving the vehicle. The cruise control is disabled when these warning lights come on as well. I've been informed by an ASE certified mechanic that the abs control module needs replacement. I've learned this is a known issue for my and similar Ram trucks and that Stellantis has the part on back order while it is in "engineering review". If my traction control, anti-lock brake system, and electronic trailer braking system is affected by a failed abs control module and it is a known issue across many vehicles and the part is in "engineering review" I belief this should be covered by Ram under a recall.

Intermittently loses ABS, traction control, and cruise control. Now throwing multiple error codes but does not "store" any codes. Lights/warnings/chimes are intermittent and random. Windshield wipers will intermittently come on as well. This is a known problem with these vehicles. Most recently randomly throws service shifter codes and vehicle shifts into neutral with no warning. The shifter has been replaced with no remedy to the problem.
