2018 RAM 3500 Complaints

Since purchasing this truck brand new in 2018 we have had nothing but problems with this vehicle. Dodge Ram failed us every time. They failed to work with the dealer and ignored every attempt to find solutions. It started with vehicle loosing power on very dangerous locations a specially freeway located in curves in the middle of nowhere. It took years to fix that problem. Multiple times we drove from the shop being told that it was fixed and it wasn't. We would drive right back in after 15 min. It took over 3 years to get dodge and dealer to replace the transmission and all electrical issues. The other problem that we have had since buying this truck is the AC. Its been always a problem we are continuously trying to fix it and its been very hard. This entire summer my children have been suffering. We are driving in extreme heat with zero ac and Dodge Ram can not produce part for the dealership to fix it. What is really unfair that original dealer tried again to charge us for something that it waste the problem. We would have paid for it and would have been back within an hour. The new dealer Peterson Dodge understood the problem and was honest with us that there is a lot more then a filter. It was me who requested to get a second opinion and get a way from Larry H Miller Dodge.

Sep 2020 purchased 6 Cooper Discoverer AT3 (LT235/80 R17) tires to replace OEM tires, mileage 12,885. On/around Sep 2022 while towing a 38' 5th wheel trailer, front end of truck started bouncing, mileage 26,334. Both driver and passenger tires where found to have tread separation. Replaced those two with same make/model new tires. All other tires where rotated and balanced. New tires went to inner rear wheels. On/around Aug 2023, once again while towing large 5th wheel trailer, front of truck started bouncing when turning to the left, muted vibration when turning to the right. Tire shop found passenger front tire tread separation again. This was one of the orginal 6 from 2020, mileage 33,762. Since 3 of the 6 tires failed I replaced all 7 (spare included) Cooper tires at my expense.

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. I want Ram to pay for this and to expedite the replacement parts and the NHTSA to do their job and serve us the consumer instead of the manufacturer. I am seeking legal recourse too. I attached the repair code report derived from my Blue Driver code reader tool.

ABS failed during a panic stop causing the vehicle to skid. Received a notice on the dash to “Service Electronic Braking System” followed by the ABS and traction control lights coming on then off a number of times. It is my understanding that the Hydraulic Control Unit has failed, and FCA is aware of this issue. Failure of ABS in a large heavy pickup truck is dangerous, and FCA should issue a recall to repair the affected units.

The contact owns a 2018 Ram 3500. The contact stated that while driving at an undisclosed speed, the ABS and traction control warning lights were illuminated. Additionally, the Service ABS and Service Brake Assist messages were displayed. The vehicle was taken to the dealer, where it was diagnosed that the hydraulic control unit needed to be replaced; however, the replacement part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 64,826.

The contact owns a 2018 Ram 3500. The contact stated that the ABS and brake warning lights was flashing on the instrument panel while driving at various speeds. The vehicle was taken to a dealer where a diagnostic test was performed; the diagnostic showed a faulty computer module had caused the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 44,000.

The code C0020-01 ABS Pump Motor Control - General Electrical Failure popped up. This happened with 53172 miles on the odometer. Looking on the Cummins Forum, this happens often to the 2017 and 2018 Ram 2500 and 3500 pickups.

I purchased my 2018 Ram 3500 new, in July of 2019. Since then, the HCU/ABS Module has failed 3 times. The first occurrence was at 4391 miles, the second was at 24768 miles, and the third, was yesterday at approx. 45000 miles. The "Service ABS System" light goes on and off intermittingly, which shuts down cruise control and other electrical components. The brake pedal at times feels stiff when brakes applied. This repair is close to two thousand dollars. I've read the other complaints while researching this issue. Something needs to be done by RAM to correct this safety, and excessive cost to owner issue.

Anti lock brake service light came on repeatedly and vehicle was taken to South County Ram dealer in St. Louis and they scheduled a service appt in July 2022 and they indicated an antilock module was required and did not have part due to manufacturer and did not know when part would be available. The vehicle again was taken to same dealer on July 10, 2023, and same story. This was reported to Chrysler Complaint line that same day and no response from manufacturer. How can an important safety part not be available? How can they continue to produce vehicles and not have replacement safety parts?
