2018 Ram 1500: ABS light or ABS activating

Filed Oct 21, 2026 · Brakes, Suspension · LA

The ABS, brake, and traction-control warning lights on my 2018 Ram 1500 Rebel first appeared in June 2026 and are currently illuminated. During abrupt braking, the rear of the truck can slide sideways, making it difficult to maintain control. In June 2026, I was traveling approximately 50 mph when another vehicle pulled out in front of me. I applied the brakes, and my truck slid sideways off the roadway before stopping in the grass. There was no impact, visible damage, or injury, and no police report was filed. The exact incident date is unknown. The vehicle had approximately 130,000 miles at the time, based on an estimate of my regular driving mileage. The braking problem continues. I leave additional following distance because I am concerned about losing control if sudden braking is necessary. This creates a risk of a collision or another roadway departure. Owner diagnostics using an Autel scan tool recorded active code C2200-49, described as an internal electronic failure of the anti-lock brake module. I suspect an ABS module malfunction, but the cause has not been formally confirmed by a dealer or independent service center. The original OEM ABS module remains installed and is available for inspection upon request. No solder reflow has been attempted. The truck also has an abnormal ride height, and the steering wheel is off center when traveling straight. Aero mode works when selected manually, but the truck no longer automatically enters Aero mode while driving. Whether these symptoms are related to the ABS problem is unknown. I contacted Mopar Cares about the concern and was directed to the dealership to discuss possible goodwill assistance.

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

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”.

There are countless number of individuals like myself who have paid good hard earned money to own these trucks only to find out that everyone I know has endured the issue with the ABS module it seems. And online that's all you can find now me owning other manufactured vehicles I've never encountered this issue before. But I don't understand how this is a known part that will fail and when it does fail it's up to the owners of the truck to have to pay out of pocket thousands of dollars to get it repaired after spending more than $50,000 to be able to own the truck. I can't imagine the other owners who are not able to afford these costly expenses to get repaired immediately and are forced to continue driving on the road ways endangering themselves and other innocent lives on the road ways
