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.
1. ABS pump failure, stable tract for steering. Available for inspection if requested. When this warning light comes on cruise control will not function. 2. If ABS failure cannot slow down in a timely manner danger to occupants. 3. Yes 4. Unknown 5. Yes, warning lamps appeared at 15,000 miles. Would like to see this be a recall because numerous other owners have this same issue.
ABS Control Module and/or Wheel Speed Sensors is causing the abs warning light and traction control module light to go on and off intermittently for over a year causing the cruise control to not engage or to disengage-??
The warning chirp occurred and the ABS and ESC lights came on the first two times. The incident happened so quickly I could not clearly determine which warning lights illuminated. On April 18 with just over 39,000 miles on the vehicle the chirping alarm and the ABS and ESC light illuminated. In addition two warnings appeared in the dash: "Service Antilock Brake System" and "Service Electronic Braking System." The warnings happened multiple times per minute in some cases. Other times the vehicle would go for many miles without the warning. Every time the warning chirp was heard the cruise control would disengage. I did not notice any problems with the brakes of the truck. In researching the issue I learned that many people are having this problem. I contacted Ram and they directed me to a dealer who diagnosed the C0020-01 fault code and that the hydraulic control unit (HCU) for the ABS system was defective. According the the TSB Ram has put out about the issue the ABS module could also be bad, but the first part of the repair it to replace the HCU and if the problem persists to then replace the ABS module. Ram apparently has an inconsistent level of support for owners experiencing this malfunction with some getting the repair done out of warranty, while others have to pay for the repair. Because it is brake related it seems this should be an item replaced as a safety issue, no matter what the mileage on the vehicle.
The abs system has failed on my truck and many more possibly by a dealer defect and no recall as of now. When the abs warning light comes on it also puts up a warning light for the electronic braking system and you aren-??t allowed after that to set the cruise. Anytime you hit a bump or turn the wheels or just randomly at any given time the lights come up on the dash and it chimes which will drive anyone nuts. With the electronic braking system not functioning properly could potentially lock the brakes up on the truck in my opinion knowing how it functions. Which in my opinion is a safety hazard. Also I might add that taking my vehicle to my local dealership is a complete waste of time as the diesel mechanic up there is terrible at his job. He has misdiagnosed two of my trucks and I believe he had something to do with a transmission going out in one. He -??fixed-?? it then 3000 miles later the transmission completely destroyed itself which made me have to trade the truck in. Also the traction control system does not function when the abs light is on. In doing research I have found many many people with this same problem.
Cruise control intermittent function...may not turn on, may not turn off, may not disconnect or cancel at speed, may not cancel at speed with brake pedal. Bought the truck in March, 2020. No problems until June 12, 2020, when it failed to work consistently. Dealer wants $150 to diagnose, even though it was reported to fca in may of 2018. Web information shows widespread problems...2 links I found: Https://www.equipmentworld.com/Ram-trucks-caught-up-in-large-fca-recall-over-defective-cruise-control/ https://www.ramforum.com/threads/cruise-control-stopped-working.66362/ I bought the truck with 50K miles, now has 53K miles.

Cruise control failed to disconnect. Upon repeated attempts to disengage the cruise control unit, the speed increased incrementally with each attempt. Holding the cancel button caused the unit to appear to disengage, but releasing the cancel button caused the unit to reengage and accelerate. Now, unit is inoperative.
