2018 RAM 2500 Problems

Abs light flashing on and off,

In February, 2023 I bought a 2018 Dodge Ram Big Horn to pull my 30 foot travel trailer. This truck is used for towing approximately 4 times a year pulling a travel trailer to and from the beach/mountains. In May of this year, we were at the beach and the ABS light came on. Since we were coming home the next day, I figured it was something simple and, once home, we would have it checked out which was done by our personal mechanic. He informed us of the problem and explained about the recall on the HCU unit. To this day, I have never received anything about this recall from Stellantis. He advised we take the truck to the dealership and have the recall fixed. We did as he suggested. It was confirmed by the dealership that it was the HCU and the part to fix it is unavailable. The service department technician gave me a phone # to Stellantis to call which I did the next day. Stellantis employee was extremely nice and explained to me that the parts were not available at this time and I could check back with the dealership for a loaner or I could rent a vehicle at no cost to me. According to the dealership, no 2500 trucks are loaned out. So I asked about renting one. I was told to call and see if I could rent a truck for towing but it had to be from a reputable company like Hertz, etc. I did find a truck and the cost was $89.28 per day. Stellantis only approves $60.00 per day and the remainder I am responsible for paying. Now, not only am I paying for a vehicle that I'm afraid to drive, I'm expected to pay part of the rent on a vehicle to tow my travel trailer so my family and I can go on vacation. This is unacceptable to me. I feel I have been given a run around from everyone who I have talked to. And, I'm not any closer to getting this issue resolved.

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 NHTSA and the manufacturer with questions and asked for a timeframe for a fix and have received nothing.

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!

The contact owns a 2018 Ram 2500. The contact stated that the vehicle experienced excessive and premature front tire tread wear. The vehicle was taken to Discount Tire, and the contact was informed that the front-end alignment mechanism was welded, which prevented an alignment from being performed, which caused the premature tread wear. The technician associated the failure with NHTSA Campaign Number: 19V021000 (Steering). Additionally, the contact stated that the ABS warning light illuminated, followed by a continuous warning chime while driving. The contact associated the failure with NHTSA Campaign Number: 24V896000 (Service Brakes, Hydraulic); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was contacted and associated the warning light with the recall. The vehicle was not repaired. The manufacturer was notified of the failure and confirmed that parts were not yet available. The failure mileage was approximately 65,000.

The truck started with a death wobble in the steering. Ball joints,bushing,stabilizer bar replaced front end work was done. Brought to the dealership approx 4 times for the same steering problem. It still has a small wobble pulling to the Rt or left. Steering was very loose but has been tightened up with a replaced steering shock. But the steering wobble continues had the steering gear box replaced twice. Dealership does not know how to fix the problem.

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 vehicle has experienced repeated failures of the variable geometry turbocharger (VGT) electronic actuator. The actuator intermittently fails to move the turbo vanes to their commanded position, resulting in fault codes related to turbocharger performance and actuator position. The failed actuator is currently installed on the vehicle and is available for inspection upon request. This failure creates a significant safety concern because the engine can suddenly lose turbocharger performance and enter a reduced-power or "limp mode" condition without warning. During these events, the vehicle experiences a substantial loss of acceleration and power, making it difficult to safely merge onto highways, pass slower traffic, or maintain speed while towing or traveling on grades. This unexpected reduction in power increases the risk of a rear-end collision or other traffic incident, particularly when operating in normal highway traffic. The condition has been reproduced multiple times and confirmed through diagnostic trouble codes. The issue is consistent with a malfunctioning VGT electronic actuator. Numerous other owners of 2013-2018 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins engine have reported similar failures involving the electronic actuator, suggesting this is not an isolated incident. Prior to complete failure, the vehicle displayed intermittent warning symptoms including a Check Engine Light, reduced exhaust brake performance, and occasional turbocharger-related diagnostic trouble codes. The symptoms became progressively more frequent before the actuator ultimately failed to operate reliably. In some cases, cycling the exhaust brake temporarily restored operation, but the problem continued to return and worsened over time. The vehicle has been diagnosed using standard diagnostic equipment, and the fault has been confirmed through the presence of turbocharger actuator-related diagnostic codes.

My HCU is out and constantly dinging at me for no traction control and ABS. I know this is recalled and I have been waiting over a year and FCA still doesn't appear to have a remedy for this.

The vehicle had multiple unresolved safety defects from the time of purchase. The radio and electrical system never functioned correctly and could not be repaired despite repeated dealer visits. The stabilizer bar failed and fell out while driving, causing loss of steering stability. The vehicle is currently subject to an open federal safety recall for ABS/ESC/traction control loss with no repair remedy available. These defects created a serious crash risk and caused loss of safe use of the vehicle. The manufacturer and authorized dealer failed to repair the vehicle.

Truck def system error derates vehicle speed to 5mph in 85 miles. This is unacceptable as no dealerships are open on weekends or in the middle of nowhere. This EPA rule will get folks killed as folks driving 5mph on freeway towing a big trailer will get run into real quick. Vehicle should NOT cause you to slow to 5mph if a pollution control device has issues. Please investigate.

•Side curtain airbag malfunction front driver's side. The truck has a warning light for the airbag and the computer diagnostics says it is a side airbag malfunction. The vehicle is well kept and has not been damaged. Mopar does not lost this malfunction and recall as included in my VIN •Cruise control malfunction The cruise control sporadically does not turn on when the button is pressed. The button may need to be pressed a dozen times before it activates and cruise control is available to be set for a given speed and then engaged. This has occurred since purchase brand new at the original dealership at less than 25 miles on odometer. Mopar does not list this malfunction/recall for my VIN. •Hydraulic Control Unit recall difficulties. The dealership has stated multiple times it has no replacement parts to do the recall repair covered under NHTSA Recall # 24V-896.

The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that the traction control, parking brake light, and brake light were all illuminated. The contact stated that the air bag control unit was replaced under warranty; however, a month later the air bag warning light was illuminated again. The dealer was contacted. The manufacturer was made aware of the issue. The failure mileage was 50,000. VIN tool confirms parts not available.

Uconnect screen not working properly due to delamination. When driving the screen will ghost click creating a beeping sound with every ghost click. This could be several hundred peeps per minute. The back up camera will come on while driving forward. In bad weather when you want the defrosters on it will not allow it or stay on defrost. It will switch to all different vent positions, change the air temps so you can't get your window clear. If you try and change it, it will immediately change it. I was pulling a 5th wheel through the mountains and it started to pour rain. I desperately needed defrost and it would not work properly for this reason. If you turn off the screen it will turn right back on. If you turn the volume down to zero you still hear beeping. This is very distracting as a driver. I can't even turn the radio or system off. The radio constantly is changing station and switching from FM to AM or Siri. You can't do anything to stop this ghost clicking.

The radio screen has delaminating which causes random pushing of buttons on the display. This is a known issue with dodge radios and has been labeled as “ghost screen”. This is a major concern during the day as well at night while trying to drive. The distraction from the constant screen changing is a major concern. It is unavoidable to focus on the screen instead of the road while this is happening. Dodge knows of this problem and the repair cost is unaffordable. I feel for the safety of drivers and people on the road, this needs to be addressed. I have videos of this occurring but am not able to upload videos, only photos which do not show the event happening. I would like the chance to be contacted so I can share the video of this happening to express my concern, as well as the concern of many others. Thank you

Recently the radio and display system in the vehicle stopped working properly. It was basically ghosting all commands. It could not be controlled by knobs, touch screen or voice command. the dealer stated that the screen delaminated and was causing the issue. This is a safety concern because the radio was calling 911 randomly and I was unable to stop it, it was turn on and off features in the vehicle. It's very dangerous. there is a wide know problem for these delaminating screens and this should be recalled and fixed.

The traction control/service abs system on dash came on following the loss of vehicle cruise control while driving on busy 3 lane of traffic during hill climb causing instant loss of vehicle speed. Was last told by local mopar dealer no parts available, no idea when available. Vehicle had no cruise or traction control. Only 39,000 miles on vehicle currently. Independent service center pulled code C0020-01 abs pump motor control- general electrical failure. From ECU

The ABS - Anti-Skid lights come on and off intermittently while driving, or it's actually done this just sitting still a few times. When it first started around July 2023 the truck had about 90k miles on it. I called the dealership, they said keep driving it till it stayed on all the time so they could track what was causing it. Well it never stays on, it is on/off at random. The random occurrence nearly caused a bad wreck while driving onto an on ramp wet road. The truck dinged as I was making the turn, it started spinning sideways and when I got stopped, I was sideways, I had to move quickly to get out of other cars way. When I tried to go it spun around the other way sideways, stopping traffic. I was lucky the other cars brakes worked or I would have been T-Boned. If I had been pulling the trailer or boat there would have been no way to control the spin or brake sliding, which I am positive would have been a bad wreck. I was not going too fast either, about 30-35 when all this happened. Dodge Ram company needs to fix this issue NOW before someone gets killed. I have an excellent driving record and want to keep it that way. I cannot pull my camper, boat or equipment trailer now cause I'm afraid this will happen and not be so lucky. Sad thing is, Dodge knows about this and are doing nothing about it.

Hydraulic control unit was replaced July 2020 (ABS traction control lights coming on MEANING, NO ABS NO TRACTION NO 4 WHEEL DRIVE.) Hydraulic control Unit not working AGAIN. I have NO ABS, NO TRACTION, NO 4 WHEEL DRIVE, AGAIN. CHIME GOING OF CONSTANTLY AND DEALERSHIP HAS HAD "PART ON ORDER SINCE JAN 2023"

The contact owns a 2018 Ram 2500 equipped with Michelin Tires, Tire Line: LTX MS2, Tire Size: 245/75/R17, DOT Number: [XXX]. The contact stated that while driving at an undisclosed speed, the low-pressure tire warning light illuminated, indicating that the passenger’s side rear tire pressure was low. The contact pulled over and inflated the rear passenger’s side tire, but the warning light illuminated again days later. The vehicle was then taken for an oil change at dealer, and a slow leak was found on the side of the tire. The tire was not replaced by the dealer. The vehicle was taken to where the tires were purchased, and it was diagnosed that there was a slow leak through the sidewall of the passenger’s side rear tire, and the tire could not be repaired. The tire was replaced. The manufacturer was notified of the failure, and the contact was advised to return to the store for the tire to be evaluated. The failure mileage was approximately 57,414.

Hi I have been driving for over 42 years & never had a tire valve fail on me. This past winter we drove cross country, form Pennsylvania to Arizona, pulling a 26' trailer. I am meticulous about monitoring my tire air pressure. We were heading back home in April & my TPMS system set off an alert that my driver's side rear tire was losing air. We pulled over & I changed out to our spare. I went to inflate the tire & discovered the leak was at the valve. The rubber had delaminated from the threaded tube. I had tire replaced just north of Nashville Tennessee. When we got home, I went to perform a tire rotation & discovered that the new tire(carried as a spare) had a bad valve. Firestone replaced that valve. 2 weeks ago, on my way home from a doctor's appointment, I had another valve fail. Again Firestone replaced it. My concern is 3 valves failing in 3 months time. Tires were purchased new 6/2024, valves were allegedly changed. 3 valves failures in 3 months from different Firestone locations separated by 1000 miles. I am looking to get a new set of tires before we go away again. I am leery of using Firestone, because of defective tire valves. Can you please look into this matter, and let me know the outcome ?
