This recall notice, was first identified in September or October, with the Official Communication issued in November of 2024. How long am I, or anyone expected to endure the nuances of this recall. We are well beyond 6 months now with no remedy, and it does not appear as if RAM\Stellantis is concerned with a fix. They've sent a disclaimer notice, but what is the resolve to a vehicle I purchased and continue to make a monthly payment towards - but you are basically telling me don't drive. Alternatively, dealership service advisors call me every six weeks to come in for a diagnostic ( not free of course ) only to say well it is related to the HCU so there isn't anything we can do right now. When\If I drive my vehicle I have to listen to a buckle your seatbelt type of alarm the entire drive. Its not only mind numbing its traumatic. …
Pulling a travel trailer in the mountains on vacation this month my Service ABS light started coming on and off intermittently and the alarm would sound each time. Each time my cruse control would turn off and I wasn't sure if my emergency ABS brakes were going to work, or not, if I needed them to pulling my trailer with my wife in the truck. I was 1,500 mile away from home and this created a stressful circumstance for me the rest of the trip. Upon arriving home, I discovered on the web that this is a know problem with Dodge RAMs of this year model. I also saw recall notices associated with 2018 models, just one year younger than mine with the exact same symptoms. Obviously, this problem didn't get fixed for the 2018 model year. I am quite concerned that my truck may not be safe and the ABS problem needs to be addressed. …
On my 2018 RAM 3500 beginning on Memorial Day 2023, the instrument cluster began flashing with a loud door type chime. The cluster began cycling through messages including Service Electronic Braking System, ABS Failure, and illuminating alarms. Upon testing with a code reader I was presented with the following codes: C0020-01 ABS Pump Motor Control - General Electrical Failure and U0402-00 Implausible Data Received from TCM. Upon internet investigation, I discovered this is not an uncommon problem with several hundred reports available on ramforumz.com and other sites. According to several complainants, the repair for this will cost in excess of $2000 with one complainant stating this has had to be repaired twice as the replacement components are also faulty. …
The service ABS braking system warning flashes on with a chime frequently when driving. This started 3 weeks ago. According to the Ram Forums this is a common problem with 2018 trucks. My truck is a 2018 with 352623 miles on it and according to the Dick Hannah dealership a part that is out of warranty. There is no replacement part since the original inventory was all pulled back from the dealerships to the manufacturer due to the incidences of failure. This information was given to me by the Dick Hannah parts manager. He said a newer more reliable version of the brake module is being built but replacements are not expected for at least 4 months. Ram knows the part is and was defective, i am out of warranty and have a dangerous truck to drive for the next 4 to 5 months then a estimated $1500 repair bill. …
ABS Module Failure, This has been a re-occurring issue that nearly caused an accident. The abs and traction control lights come on intermittently and disables the ABS/traction control emergency braking system. The issue has existed for 2 months, the dealer tells me it needs a new control module which is not available till some time in 2023. There advise was watch my following distance and maintain lower speeds. Unfortunately yesterday the light came on and stayed on for 50 miles plus, due to an accident on the highway all traffic had to stop quickly, when i applied heavy braking my wheels locked up and the truck started to slide sideways, i was able manually get control by fluffing the brakes but had i panicked i would have had a collision. when i got the truck to a full stop i was inches from a small compact car. …
Hello, I have an issue with the ABS Braking system on my 2018 RAM 3500 with only 50K miles on it. The lights are constantly coming on and off telling me that my ABS system needs servicing. this has been going on for two weeks. I was able to troubleshoot the problem and it says that my ABS pump and Module needs replacing. I was going to replace myself and when I ordered the parts from MOPAR they told me it was a 2 month lead time which I thought was unacceptable being such critical components to a vehicle. This week I almost rear ended another vehicle because the brakes failed. I have been online reading about the stories of these same complaints from many RAM & JEEP owners. How this company is getting away with safety issue is beyond me as this is going back to 2023, how are there no safety recalls on this not issued yet and customers not being reimbursed for the repairs. …
Warning lights for the ABS and the Electronic Brake System illuminated while driving, stating the systems must be serviced. The Cruise Control would either turn off or become nonfunctional. The tone would sound and the warning lights would illuminate. I took the truck in to the dealership after it happened but the lights would not come on while I was there. The dealership told me they could do nothing about it. After that, the tone began to sound and the lights came on again. We finally made it to the dealership when they could see the warnings. The service technician inspected the ABS and found that the ABS HCU had shorted internally. Further inspection found the ABS Module also shorted internally. Two trips were made to the dealership because the dealership did not have the parts in stock. …
I have not been involved in an accident yet. You can't drive the truck because the warning goes every 2 minutes. The brake hydraulic control unit has failed and they will not fix the truck. I can't pull my camper. I have at least 6 hours on the phone with Ram and they say there is nothing they can do. The dealer ship says they have the part that is on the truck now, but Ram will not allow them to install it. It's not the new part. Mean while my truck is useless until they fix it. They have been aware of this issue since 2017 and they still do not have a replacement part. The right thing for them to do is put the they have on hand on it so I can a least drive the truck. The truck has 90k miles on it. The vin # [redacted] . My contact info is [redacted]
