2018 RAM 3500 Complaints

2018 Ram 3500 - ABS system/Electronic braking system failure at 5583 miles. ABS/traction control and service electronic braking system display on dash, also audible chime with cruise control inactive. Took to dealership for diagnonis and code C0020-01 is active. Reccomended replacement of HCU which is common for these vehicles. Truck is out of warranty and estimate is $1080 for repair, which does not include the $301 I spent on diagnostics. There needs to be a recall on these Chrysler HCUs as they are a known issue and related to the braking system. Why do I see recalls on items such as malfunctioning tailgate latches but not braking systems?

ABS/HCU are defective and must be replaced. We have no ABS or Electric Brake System which has also caused the Cruise Control to not work. This is a known issue with 2018 2500/3500 models but recent recalls don't list this particular year within the scope fo the recall. Online research found a multitude of 2018 RAM trucks with the same issue - Recall Z20 should be modified to include 2018. My 3500 was purchased for towing as are most 2500/3500 models and this is not acceptable to not have ABS as well as Electric Brake Systems. Will be months to get the parts for repair due to nearly over 300,000 Rams and Durangos alone in the current Recall Z20 affected. (Incident was stopping to avoid hitting deer and no ABS. Next day when started up vehicle warning lights: Svc ABS and Svc EBS.)

The contact owns a 2018 Ram 3500. The contact stated that while driving, the ABS and Traction control warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the ABS control module and HCU needed to be replaced. The vehicle was not repaired. The dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 44,000.

ABS and Traction Control lights and DIC alarms came on while driving. They stayed on for a few minutes then went off. Also the service trailer brake system message came on. This has happened several times now turning off cruise control too. I reseated all fuses and went for two weeks before it started happening again. Happens sometimes as we go over expansion joints or hit potholes while driving at highway speeds. I notice several other reports of this here at NHTSA site and various RAM forums across various RAM years.

The contact owns a 2018 Ram 3500. The contact stated while driving 45 MPH, the antilock brakes (ABS) and the traction control warning lights illuminated. The contact took the vehicle to an independent mechanic, where it was diagnosed with needing the ABS module and the anti-skid controller to be replaced. The vehicle was not repaired due to parts being on back order. The contact called the local dealer and made them aware of the failure. The manufacturer had been informed of the failure. The failure mileage was 70,780.

I am getting two errors: 1) Service anti-lock braking system with the ABS light on; 2) Service electronic brake system with the traction control light lit.

Abs and traction control system stopped working with only 33000 miles. Dealer states module and pump need replacement. No warranty as vehicle is 4 years old as no driving during covid. This has happen to 1000's of ram trucks. Repair is $1600. Will have to drive with out repair.

On Sept 11, 2022, we experienced a heavy rain shower while traveling along I64 westbound in VA. My 7 year old daughter in the back seat informed me the headliner was wet in the rear driver side corner. Upon further inspection the passenger side headliner rear corner was also wet. I inspected the top of the ruck, no damage was noted and the seals all appeared to be in place. There is a Jereco High Rise cap on the bed of the truck and we were pulling a 38' travel trailer at the time. The posted speed limit was 70mph on the stretch of road where the rain was encountered, however we were traveling between 40-60 mph during the rain event. No immediate safety risk was present. However, I'm concerned water intrusion may eventually result in an electrical fire or failure of a required safety device. Should water find it's way into a hidden harness or other electrical component such as the CHMSL (VOQ 10968851) or factory subwoofer which is located below the area which leaked. The vehicle has not been inspected or repaired by a dealer as it is just out of warranty. I did report this to RAM via Ram trucks on-line owner's portal. No warning lamps, messages have been observed at this time.

The transmission in my truck has been having problems starting on 9/25/18. On 7/21/22, Grey Chrysler replaced the solenoid in the trans and also did an update. When I brought truck back after the same code, PO871, was thrown again on 08/30/22, I was told the warranty company couldn’t recreate the problem so they would not be fixing my trans. This is the same trans that is in the 2019-2022 Ram 2500 trucks and has a recall on it for the SAME problem.

ABS and EBS sytem is shutting on and off on highway at speeds. This is a random event that started at about 20,000 miles then went away for about 6,000 miles then came back at 29,000 miles whil on a 1,500 trip and is now not going away. The system shuts on and off constantly with chimes and alarms to "service ABS/EBS. I have the truck at the dealership and they advsied it needs to have the ABS pump and control module replaced. I have looked on the internet and see several hundred complaints for the same issue. The delaer says this is not a recall and is not covered by warrenty. To me this seems like a safety issue that is being ignroed by Chrysler corp / Ram. They are looking at the numbers and not enough people have been in accidents to justuify the cost of a recall. I have a video of the issue system turning on and off constntly at about 62 MPH as I enetered the freeway from and on ramp to merge in trafic.
