    Main Frame is cracking between the cab and bed of the truck. I took it to my local Ram Dealer in Chico Ca. Chuck Pattersons Ram they inspected it and told me not to drive it because it is unsafe to drive. The service manger said the frame did not crack from anything I did. It looked to him like it was a factory defect. They are welding across the top of the frame when mounting a bracket which is weaking the frame. This is where my crack developed from.They told me to contact Ram customer care arbitration as they should be able to authorize a replacement of the faulty frame. Without any explanation Ram arbitration denied the claim. I asked them to send me something in writing saying why they denied the claim and the person on the phone hung up on me. This is why I am contacting you.

    I had a new Hydraulic Control Unit (HCU) replaced with the new style that Ram expedited for me. This new unit gave me the ABS / TC Lights on my dash. Took it back to "2" different garages, they both confirmed that the pump was not being activated. Which means the 2nd HCU was a bad part! Ram / Fiat is fully aware of this problem! This needs to turn into a Class Action lawsuit! They are still putting out new RAM Truck for dealers, and they are not supporting their older Trucks! Very frustrating!!!!

    I recently purchased this 2018 Ram Dually for work on our farm. After 1 trip all the ABS/traction control/4wd and cruise control wont work. It seems that this a safety issue that ram will not address. I would like to file a complaint that if I had known about these issues, I would not have purchased this truck. It is unsafe driving and with no ABS and cruise control or traction control. I depend on the 4wd in our farming business and not having this has caused me lost income because I simply could not get the job done and had to give the job away to others.

    ABS light is on and while driving a message appears on dash which indicates "service electronic brake system." It comes on and stays a few seconds and goes off and then comes back on. Mechanic has diagnosed and found code C0020-01 which indicates ABS pump motor control general electrical failure. This truck only has 16,000 miles on it.

    Failure of the ABS Control Module. Warnings displayed on Dash "Service Electronic Braking System" "Service Traction Control." and ABS/Traction Control warning lights light intermittently While Driving. This happened the First time around 35,000 miles on a cross country highway trip, and has come back again for the last two weeks. around 76,000mi. Slight Research Has shown me this is a very common problem on 2017-2018 RAM 2500,- 5500 trucks.

    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. This needs to be investigated and frankly needs to be a national recall on these vehicles, it is a lot more dangerous than a tailgate lock issue. I am concerned with the cost, but more concerned that replacing the noted components may not solve the issue in the long term resulting in additional costly repairs.

    I purchased this vehicle new off the lot with only 11 miles. At approximately 10,000 miles the ABS system started to malfunction intermittently. System checks via OBDII scan tool indicated a hydraulic control unit failure. This part is impossible to obtain as all dealerships contacted in a 100 mi radius report a backorder with prices for repair inflated due to demand. Limited research has yielded mass complaints about this problem but no action on the part of RAM. This is my only vehicle and just like many others I cannot just park it or sell a defective vehicle without a substantial financial loss that I cannot afford. The HCU failure has caused my brakes to lock up when braking for an emergency stop. Without intervention from the NHTSA and other government agencies, I fear there will be several unnecessary injuries or deaths due to this known and documented common failure.

The vehicle was taken to Auto Zone for diagnostic testing. The contact stated that several unknown codes were retrieved. The vehicle was not repaired. Neither the dealer nor the manufacturer were notified of the failure. The failure mileage was approximately 112,000.
