This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Failed abs module and/or hcu. Truck is available for inspection. Loss of abs and traction control causes loss of control of truck in wet conditions when stopping or cornering. Hcu was replaced by dealer 10/12/21 @ 20,109 miles due to code c0020. (Abs pump control motor general failure) Same issue/code @ occured again @ 47,000 miles. Have not been back to dealer as the truck is out of warranty and the cost is almost $2000 for the repair. Service Abs/traction control/ electronic brake warning lights constantly go on and off and eventually stay on. This causes abs and traction control to be unreliable and is extremely dangerous on wet roads and also dangerous to other vehicles on the road.
Antilock Braking System failure with my 2018 RAM 3500 Dually. The vehicle-??s anti-lock brake system error, also causes the cruise control and traction control systems to become inoperable. The old HCU is currently on the vehicle for inspection by additional parties. This issue increases the risk to safety to vehicle occupants and public, for control of the vehicle, under wet or slick road conditions. As mitigation, while dealing with the defective part/system, drivers need to remember to operate vehicle differently in adverse conditions. Both a local shop and the Doge/RAM dealer confirmed the HCU needed to replaced. RAM MOPAR would not sell the HCU part to local shop for quick repair. Then I waited 5 weeks for service appointment at the local Dodge/RAM dealer, 1 week for estimate, 1 week for HCU part to arrive and schedule appointment, then finally 4 weeks to get appointment to (hopefully fix the problem, plaguing RAM owners due to the defect). I already had the unit replaced at 41K under warranty by the Dodge/RAM dealer, but unfortunately I am 1K miles out of warranty (75,000mi) on the second event, and estimated to cost me ~$750. The defective Hydraulic Control Unit, HCU, started to fail around July 1, 2024 sending service messages intermittently, and progressively got more as time went on. Both a local shop and the Doge/RAM dealer confirmed the HCU needed to replaced. The old HCU is currently on the vehicle for inspection by additional parties.
ABS/ HCU ISSUES- BLINKING LIGHTS, Hendrick Dodge service in Cary, NC has the 2018 Dodge Ram 3500 in for service to replace the draglink that was another recall for 2nd time to replace the draglink this time. I know there is class action lawsuit 2023 file against FCA on the ABS modules and HCU's for 2017 &2018 ram 2500 and 3500 trucks.
We purchased the vehicle as a back up for when my husbands every day work truck is in need of service. The truck is from 2018 and now has about 40,600 miles because it isn't used often. The truck would start flashing a light saying service anti-lock brake system sometimes during the time the light was flashing it felt like the brakes struggled a little. We have sent it in to get repaired and they quoted us over $1300 of repairs because it needs a an abs module and pump.
Intermittent issues with the cruise control system and the ABS electronic braking system. The lights will flash on and off and the beeping is constant. If beating on the side of steering wheel will allow you to turn cruise control, then the ABS system will be okay for unknown reasons it will start flashing again and cancel the cruise control and the system will start flashing check the ABS electronic braking systems.
Truck wouldn't stop antilock brakes did not work. Been trying to get 68347098ab and 68143491ab for the last 3 years from ram but been on backorder for that long. Was going down gravel road and trying to stop but wouldn't one wheel locked up and truck went into ditch smashing fender and hood.
Lights and chimes constantly signaling trouble with ABS/Traction Control system. OBD 2 indicates ABS Module failure but have read online it could also be HCU pump, a connection problem or a combination of issues. At this point the warning lights are on constantly while driving. No cruise control available. Talked to dealership and informed they are aware of the issue as it is wide spread with several models. Long back order and wait times for upgraded parts. Seems clear it is a safety issue.
No antilock brakes for 3 years. The parts have been on back order for 3 years and still no sign of when be in. Always in back of mind if brakes will work or not when trying to stop truck.
A diagnostic code has been displayed for the Anti-Lock Brake System - C0020-01 -?"> ABS Pump Motor Control - General Electrical Failure. Going over a bump in the road will cause the ABS system to deactivate the cruise control. The diagnostic code can be cleared and the cruise control will resume. Reading on RAM / Cummins online sites, many say that either the HCU and / or ABS Module needed to be replaced and many submitted reports to the NHTSA to start an investigation. No damage has been evidenced at any of the wheel sensors. With the ABS illuminated, it appears that the unit wouldn-??t function if needed. The clearing of codes has been done numerous times. First noticed in about January 2024.
We bought this truck from a dealer in March of 2023. We were never informed by the dealer that the truck had this issue. ABS light and traction control lights come on & stay on for periods of time. Sometimes lights come on & off repeatedly while driving along with chime on & off. When lights come on, there is no cruise control available to use. I took it to the dealer we purchased from over a year ago and was told there was no solution for the problem. They said it was under an engineering review. No parts were available for a fix. I have documentation from the previous owner that this was occurring when he owned it in April of 2022. Since we pull trailers with equipment and also a large fifth wheel camper, we feel very unsafe when the ABS braking system and the traction control goes out while driving this vehicle. It is available for inspection upon request. When will there be a repair for this?
1. Serv anti-lock brake system, . 2. service electronic braking system. ABS light on and traction control light on. Diagnosed issue is Hydraulic control unit and possible module antilock brake system. Dealership does not have the parts for repair. Manufacturer refuses to put a recall notice even though several complaints have been issued by the RAM community.
Abs and electronic control system lights intermittently come on and off constantly and have been for 25,000 miles. When it started happening Chrysler knew what the problem was hcu and abs module is malfunctioning but unfortunately no parts were available and couldn-??t tell me when they would be available. I-??m just now putting in the complaint due to just learning about this site.
HCU / ABS light lmaps started flickering and now stays on I only have 42k miles on this truck. When I researched come yo find out everyone is having the same problem with the 2017 and 2018 this is a safety problem that needs to be fixed. I was on a wet road went to stop abs light came om I slid alot scared me to death considering I was pulling a 10k lb trailer behind me. Anytime it rains I'm scared to drive this truck rear wheels spin way too easy especially with traction control not working and I don't trust the stopping after my incident. With so many more customers having this issue please have this fixed asap make it a recall someone will end up getting seriously from this issue and many have notified this site FIX THE PROBLEM ITS NOT SAFE
The ABS system failure and traction control lights came on and have been coming on intermittently. This failure has caused the vehicle not to retain cruise control and brake and stability control being reduced or potentially off could result in an accident. Upon research, this is a very common and costly issue not covered by warranty work, this seems to be something Ram should fix as it is a safety issue.
The component that failed was a brake module. It caused the loss of ABS and TCS. The part was claimed to be on backorder, and it took seven months for the part to be replaced. This forced me to drive an unsafe vehicle.
