2015 RAM 1500 acceleration problems

VEHICLE SPEED CONTROL

The ABS, Traction Control, & Trailer Braking system no longer function. The vehicle is still drivable, technically unsafely. Warning lights for these system on all the time. I took vehicle to my local repair shop and was told the ABS Controller Module has failed (code C2200-49 indicating an internal electronic failure within the controller). I was quoted a replacement cost of $1579 + tax. I was also told the part, 68228991AD is on indefinite backorder. I have tried to locate the part on my own and there is in fact a nationwide backorder. As of this date replacement and remanufactured modules are not available. This is not just an issue with 2015 Ram trucks but extends to other Ram model years using the same part number. This is a huge safety issue that should be addressed through a recall. It is a travesty that Ram would not maintain adequate supplies of essential safety-related repair parts for a vehicle that is only 10 years old. At this point I have no recourse except to drive the truck in this condition. I am unable to sell the vehicle due to this situation.

Subject: Request for Investigation of ABS Module Failure and Part Unavailability To Whom It May Concern, I am requesting that NHTSA investigate a potential safety issue involving the Anti-Lock Brake System (ABS) Module, Part Number 68228991AD. The ABS module in my vehicle has failed, causing the ABS and cruise control systems to stop functioning. In addition, the ABS, check engine, and brake warning lights remain illuminated at all times. As a result, the vehicle no longer has anti-lock braking capability, which increases the risk of skidding and loss of control during emergency braking or adverse road conditions. My primary concern is that this safety-critical part appears to be discontinued or otherwise unavailable. I have spent more than three years attempting to locate a replacement through dealerships, parts suppliers, salvage yards, and online sources without success. Because the required part cannot be obtained, owners are left driving vehicles with a disabled ABS system for extended periods. This creates an ongoing safety risk for drivers, passengers, and others on the road. A critical safety system should be repairable when it fails. This issue has also created a significant financial burden. The constant warning lights and inoperable safety features substantially reduce the value of the vehicle and make it difficult to sell or trade. Few buyers would be willing to purchase a vehicle with persistent ABS, brake, and check engine warnings that cannot be repaired due to the lack of available parts. I respectfully request that NHTSA investigate the frequency of failures involving ABS Module Part Number 68228991AD, the availability of replacement parts, and whether manufacturer action, including a recall or extended support program, is warranted. Thank you for your consideration and commitment to vehicle safety.

While driving on the highway with my entire family in the vehicle, truck lost power without warning and what it seems it went into a limp mode. This created an incredibly hazardous situation, exposing my family and the drivers around us to an imminent risk of a high-speed collision. Thankfully, nothing happened and no one was hurt. Upon restarting the vehicle, the check engine light illuminated, and power was drastically reduced, capping our speed at approximately 40 mph. I brought the truck to St Charles's dealership for diagnosis. Service department has informed me that the root cause of this catastrophic failure was the crankshaft tone wheel. Furthermore, I was informed that this specific issue was an unaddressed/unfixed defect on my vehicle by Stellantis. What I learned is that the fix for a broken tone wheel required dropping the transmission to physically press a brand-new tone wheel onto the crankshaft. Because this was incredibly expensive and time-consuming, Chrysler rolled out a recall remedy consisting of a Powertrain Control Module (PCM) software flash.This should be unacceptable for trucks that cost $70,000 or any vehicle. Imagine that software failed what would have happened and yet we had no idea about this.

The ABS module failed in June of 2025. Ram originally told me the part was on back order 6-8 months. In December they said there were 100 ABS modules on order for our area. In January 2026 they informed the mechanic that is doing the work that there is still parts on back order and it could be another 1-2 months. Today 2/25/26 the mechanic was told there are 265 modules on back order and it can be another 2-3 months. The truck now has a throttle body control issue that is stemming from the ABS issue. The truck is not operable at the moment because of this back order. I have been waiting for 7 months for this part and there are no alternatives on the market. If Ram does not get a part available for me I will either have to find a used one that hopefully isn't going to fail or be out of a $50,000 truck. This is a problem that many people have had according to all of the RAM forums. RAM needs to find a solution because the consumer already paid for the vehicle so parts should be available.

What component or system failed or malfunctioned, and is it available for inspection upon request? ABS Control Module (Part Number 68228991AD). Failure of this part prevents the ABS system, trailer brake, cruise control, and traction control from functioning properly. Part is currently installed into vehicle and is not available for inspection. How was your safety or the safety of others put at risk? Car no longer has ABS, traction control, trailer brake, or cruise control. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. This is a know issue with 2014-2016 Ram 1500s. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. Following lights are on dashboard: Brake, Traction Control, ABS. OBD Code C2200 for internal module failure. Lights were first intermittent in the Summer of 2024. Came on permanently in early 2025. ADDITIONAL INFORMATION There is a design flaw in the ABS Module for these vehicles that causes them to malfunction. This issue affects thousands of Ram vehicles. The chip in the module that is defective is no longer being produced, and Stellantis is unable to provide replacement ABS modules at the rate they are needed. Thousands of these trucks are driving around with no ABS, T/C, etc or are sitting in shops waiting for a new module, as they will not pass state safety inspections. Stellantis will not acknowledge there is a design flaw with these modules, even though they have been listed as being under "Engineering Review" for multiple years. Due to the critical vehicle systems that are impacted, these ABS Modules must be recalled.

While driving at approximately 50 mph, my truck suddenly shut off without warning. I lost engine power, power brakes, and power steering. I was only able to stop safely because I happened to be traveling uphill. This created a serious safety hazard. The failure was caused by the crankshaft tone ring issue addressed in the existing recall. The tone ring has already been replaced, but the recall requires a dealer-performed ECM software update to complete the repair and ensure the vehicle is safe to operate. The dealership is refusing to perform the recall software update because my truck has an aftermarket exhaust and a modified EGR valve. These modifications are unrelated to the recall. The recall only involves an ECM software update, and my ECM is completely stock. Because of this refusal, I cannot safely drive my truck. I am concerned that the engine may shut off again at higher speeds, creating a severe risk of an accident. I am requesting assistance to ensure the recall is completed so the vehicle can be operated safely.

I am experiencing ABS issues on my truck. After visiting a local auto parts store to get an OBD scan, the code says it’s a bad ABS module. I called the dealership to share this information and they confirmed the code from the auto parts store is a bad ABS module. They said “oh no, you got that code huh? You’re not the only one.” The reason for my visit was because three lights were illuminated on my dash. The ABS light, the traction control light, and the BRAKE (trailer brake) light. The messages on the dash display say to service the ABS system, service the electronic braking system, and service the trailer brake system. From my research, I have discovered that many people are experiencing this same issue on similar vehicles . So much in fact that the parts for repair are unavailable at the dealership and online warehouses. The cruise control is disabled while experiencing this issue and braking performance is affected while driving. I’m afraid that my brakes will lock up on me in a hard stop event and lead to an incident.

On [XXX] numerous brake system warning dash lamps came on on your truck. I also noticed that once this happened the cruise control no longer works. The local RAM dealer could not inspect my truck for several days so I had an independent service center test it and he confirmed the anti-lock brake module had stopped working. I believe he also noted that error code(s) were detected. yes, it can be inspected. I drive the truck but do so without the use of the anti-lock brake system. Yes, the problem has been reproduced, and l've visited my local dealer and discussed the situation with them and they confirm that this has been an ongoing problem for over 2 years. Warning lamps only came on as soon as the problem started, though at the time I did not notice a problem as I did not have to slam on my breaks and make use of the anti-lock/anti-skid function. The service center and dealer both confirmed that the malfunctioning cruise control was definitely part of the module failure. Part # 68228991-AD (replaced part # 68228991-AB.

VEHICLE SPEED CONTROL

Dear NHTSA, I am writing to express my disappointment regarding my experience with my 2015 Ram 1500 EcoDiesel, particularly in relation to unresolved recalls and inadequate service from dealerships. Last year, I began experiencing significant issues with my truck, ultimately leading me to Southern Motors in Springfield. They diagnosed the problem as needing a new engine, which was concerning. However, my vehicle also had outstanding recalls, including one for the fuel pump, which I was informed they did not address and ended up being the issue with the engine in the first place but instead they informed me I would need to pay for a new engine roughly $20k. I then took my truck to Hayes Dodge Ram Jeep Chrysler in Gainesville, Georgia. While they did perform the recall for the fuel pump, I was charged $400 to update the system—an action I believed should have been covered under the recall. After this service, my truck continues to run poorly and still displays check engine lights related to a crankshaft sensor, which I understand is also under recall (number X94). This issue has not been addressed, further compounding my frustration. Given the circumstances, I am deeply concerned about the effectiveness of the recall process and the service I received. I would appreciate your investigation into this matter, as it not only affects my vehicle but potentially other consumers who may be facing similar issues with Ram trucks. Thank you for your attention to this matter. I hope to see improvements in the handling of recalls and service quality from dealerships.

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 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 which resulted from this malfunction. I have a standing Brake , ABS , Anti Skid light and no Cruise control.

COMPLAINT/INCIDENT.On February 9th 2024, I was making a right hand turn onto main Street. My speed was under 10mph, closer to 5mph. . Without any warning or MIL, my truck suddenly went from easy steering to unable to move the steering column and jerked/locked the wheel by 90 degrees to the left. In other words, the steering wheel went from the 3:00 position and locked into place at the 12:00 position at the apex of the right turn. This put me on a path to driving into a 2story brick building. I was unable to accelerate and I was unable brake momentarily. The engine sputtered a few times; and that is when the MIL lit up on my dashboard stating “electronic power steering service” and “low battery voltage”. After the lights came on, the steering was brought back to normal along with the acceleration and my brakes. After the MIL displayed, steering resumed enough to pull into a parking spot. All of this occurred within 80ft from the apex of the corner to where the truck finally locked up. Total distance traveled 195 ft from start of turn to parked. The steering column and wheel completely locked up once in parking spot. I weigh about 230 lb and I could literally hang off the wheel without the wheel moving an inch.. At home, the power to the truck did not turn off like it normally would after 30 secs. The manual neutral transmission switch was pulled, which normally does not interfere with shutdown. After disengaging the truck powered off. However, I was unable to restart and only a clicking noise was heard. A battery booster jumpstarted successfully. No MIL on dash on startup. Surprisingly, the steering came back to normal. PART NUMBERS. The EPS numbers on the outside casing are P68242957AD and TIC2794A8134. Neither of these numbers have been listed in any of the documentation provided by the NHTSA on the power steering recall nor the reopened investigation.

My truck is experiencing the “hemi tick”. Upon research, this tick is a common defect in RAM trucks that was supposed to be fixed in later models. Not true. Not only do I need to pay thousands for replacing the manifold, it will be a problem again. The hot/cold engine melds the aluminum and steel, creating a warped or split manifold. To replace it is immense labor, hence costly fees, as the bolts are too small to adequately remove and snap. If drilling out, metal could get into other parts of the engine causing severe damage. I bought this used at $30,000 miles (approx). Per my mechanic, the manifold has already been altered once. They claim it’s a safety concern, which includes “loss of power … especially at highway speeds. This is in addition to the repair costa and loss of value. The earliest appointment is a month away. Yes, it could be inspected upon request. It has been inspected by Arbos and G&D auto repair. Both whom are unable to remove the bolts and referred me to a dealership. I have an appointment with Hights Chrysler in Madison, Maine on Nov. 30th. The quotes I have received range from $500 to $2,000. The ‘warning’ is the ticking sound during idle.

While driving on the highway between Nenana and Fairbanks, AK, on August 9, 2023, I attempted to pass a slow moving RV towing a trailer. While in the passing lane, I accelerated and my vehicle suddenly loss power. I was forced to swerve out of the passing lane to avoid a collision with with oncoming traffic and the vehicle being passed. After that event, the vehicle would not exceed 3000rpms or 35mph up hills. Immediately after the event, the service engine light came on and the dash showed engine error codes. I took the vehicle to the dealer (Gene's Chrysler in Fairbanks Alaska). After inspection, they indicate that the magnetic surface of the engine tone wheel was delaminating and this initiated the sensor to cause a "limp mode" (mode that limits vehicle's speed). After that event, the vehicle also had trouble starting as though it was not receiving sufficient fuel. The dealer indicated that my vehicle's vin was not covered under the recall even though the problem matched NHTSA campaign number: 23V411. Stellantis’ own number for this recall is 66A. This recall is an expansion of recall 20V475. I feel that my vehicle needs to be added to this recall. Without my vehicle covered under this recall, my family is incurring the costs of a rental car until the new part arrives. The vehicle was dropped off at the dealer on August 23. The part is delayed and expected on October 15 (nearly a two month wait because of a vehicle defect that effects safety). The dealer indicated my vehicle is unsafe to drive. Why isn't my vehicle part of this recall? It is clearly the exact problem identified in the recall notice.

I was pulling out from my street that connects to a two lane highway. From my street you can see if cars are coming from quite a distance away. There was a semi truck in the distance going east bound in the direction I needed to torn into. There was absolutely enough room for me to merge out into the east bound lane without the semi truck even being affected. I was now about a 1/4 mile down the road and the semi was still aways back. Then, my truck started to sputter and not accelerate and as this a two lane road there at this point was nowhere to pull over. The semi was now coming up quick due to loss of power in my truck. I turned on my hazards by this time he was close and had to make an evasive lane change to avoid running into the back of me. Luckily, there was no on coming traffic. This is not the first incident of my truck losing power and almost being rear-ended. I purchased the truck from a dealer in December of 2022. They have not been of any help, and frankly they are not willing to do a thing to help. I'm at a loss and have no idea what to do. I feel I was sold a truck with a potentially dangerous recall that can cause a major car accident which could result in death. There is no resolve for this recall at this time. This recall not only puts my family at risk, it endangers the general public.
