NOTE: 11/18/22 filed a complaint with NHTSA - they will share it with manufacturer case number(ODI) - 11494143 QUESTION: What component or system failed or malfunctioned, and is it available for inspection upon request? ANSWER: ABS module problem Code : c0020-01 service electronic brake system Service Antilock brake system The display indicators for all of these systems come on intermittently. They effect the use of the cruise control as well. QUESTION: How was your safety or the safety of others put at risk? ANSWER: There is always the potential that any or all of these systems can fail at any moment when I am on the road driving; especially with 18k-20k pounds of load behind me. QUESTION: Has the problem been reproduced or confirmed by a dealer or independent service center? ANSWER: Yes. Galleria Tire Center in Pelham, Al. confirmed the display of all these warnings and also provide me with the code that I posted above on first question. QUESTION: Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? ANSWER: NO QUESTION: Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? ANSWER: warning lamps come on intermittently and stay of for random times. Always wondering if one of the systems are going to fail. We pull an 18k RV with this truck and it would be tragic if we have a system failure that results in an accident. Online posts also verify that many other RAM owners are experiencing the same problem with their trucks. This most certainly needs to have a recall on it. Very dangerous. Manufacturer has great liability and litigation exposure if they do not act on this and accidents happen. They have been warned.

My truck is a 2018 Ram 3500 with only 12,500 miles on it, and it is not driven in the winter. Recently it has been has intermittent activation of the ABS and traction lights. It has been on consistent for over a month now. I code scan showed C0020-01 ABS module general electrical failure. I search online and talking with the dealership revealed this is a fairly common issue on 2017 and 2018 trucks and the fix with either the HCU, ABS module or both. I see NHTSA has opened and investigation into the matter so I am just reporting mine as additional truck with issues. It has not been repaired yet. Thanks.

While reviewing NHTSA's website I noticed PE22-012 concerning Loss of Brake Performance on 2017-2018 Ram 2500 and 3500 trucks. My 2018 Ram 3500 recently started giving me an ABS, traction control and/or "Service Electronic Braking System" warnings. I first noticed the ABS light shortly after I most recently rotating the tires. The tires were rotated for the 3rd time on 14 Dec 2022 with 44,158 miles on the truck. I rotate all 5 tires (spare included in the rotation). I didn't think much of it at first as I was driving in PA on snow covered dirt roads the first time the ABS light came on. After that it became more frequent with the traction control light typically also illuminating. And now more recently a message on the dash information center appears after the lights come on. The lights don't always go out after a key cycle but will often turn off in the middle of a trip. I have not taken the truck to be inspected. Nor have I noticed a degradation of braking ability. I also have never had to brake hard enough to activate the ABS on this truck, nor have I tried it just to see.

44,000 MILES, 2018 RAM 3500 DUALLY 4WD ABS Traction control unit failure and this disables traction control and cruise control. No safety braking is working and there are no solutions from RAM dealers. All they want to do is swap parts until they can find a solution and that's is if they can even get parts. If ABS is a mandatory government requirement on USA roads, why is RAM allowed to sell these trucks? There needs to be an investigation of fraud and the public being put at risk of death on our highways.

The hydraulic control unit is repeatedly having problems. 09-01-2020- Inspect Brake System. Serviced at Carlock Chrysler Dodge Jeep Ram in Tupelo, MS at 19,056 miles. No parts replaced that I can recall, but the warning light and dinging stopped. The warning that was emailed to me included this information- Your vehicle's ABS Warning Light recently indicated the Antilock portion of the braking system is not functioning. If the ABS Warning Light remains on or turns on while driving, the conventional brake system will continue to operate normally unless the Brake Warning Light is on. Have your vehicle serviced at your dealership immediately. This was at 18,302 miles. 1/13/23- It sent a report with the same issue again. The mileage at this time was 45,260. The light and warning had been going on and off since at least October every time I hit a bump in the road. I tried obtaining a replacement hydraulic control unit, but it was backordered. I have another vehicle to use so I only used this one when I absolutely have to. I have read on forums that this problem is widespread and I truly believe something needs done about it. Replacing a hydraulic control unit every 30,000 miles or so at the expense of $1200 plus dollars each time is not economically feasible. The first time it was checked, the truck was under warranty. I do believe mine is extremely low miles for it's age and should not be having this issue repeatedly. 2019-2022 Have a recall, however my 2018 is having the exact same problems.
