The manufacturer was not notified of the failure. The failure mileage was 40,000.

Abs and electronic control system lights intermittently come on and off constantly and have been for 25,000 miles. When it started happening Chrysler knew what the problem was hcu and abs module is malfunctioning but unfortunately no parts were available and couldn’t tell me when they would be available. I’m just now putting in the complaint due to just learning about this site.

HCU / ABS light lmaps started flickering and now stays on I only have 42k miles on this truck. When I researched come yo find out everyone is having the same problem with the 2017 and 2018 this is a safety problem that needs to be fixed. I was on a wet road went to stop abs light came om I slid alot scared me to death considering I was pulling a 10k lb trailer behind me. Anytime it rains I'm scared to drive this truck rear wheels spin way too easy especially with traction control not working and I don't trust the stopping after my incident. With so many more customers having this issue please have this fixed asap make it a recall someone will end up getting seriously from this issue and many have notified this site FIX THE PROBLEM ITS NOT SAFE

The abs light and the traction control light come on and you get the code for a bad abs pump and hcu. Codes are C0020-01 and code C0020-16

The contact owns a 2018 Ram 3500. The contact stated while driving at various speeds, the messages "Service Brakes" and "Service ABS" were displayed and an alarm sounded. The contact stated while driving 30 MPH, the failure recurred and the front passenger's side wheel locked up, causing the vehicle to accelerate unintendedly. The contact was able to decelerate and continued driving. The vehicle was taken to the dealer, where it was diagnosed and determined that the ABS pump and the ABS module needed to be replaced; however, the ABS module was on backorder and under engineering review. The vehicle was not repaired. The contact related the failure to NHTSA Action Number: PE22012 (Service Brakes, Hydraulic). The manufacturer was not notified of the failure. The failure mileage was approximately 68,000.

The ABS system failure and traction control lights came on and have been coming on intermittently. This failure has caused the vehicle not to retain cruise control and brake and stability control being reduced or potentially off could result in an accident. Upon research, this is a very common and costly issue not covered by warranty work, this seems to be something Ram should fix as it is a safety issue.

ABS and Traction control failure. Code C0020-01. Occurs at various speeds and while stopped.

The component that failed was a brake module. It caused the loss of ABS and TCS. The part was claimed to be on backorder, and it took seven months for the part to be replaced. This forced me to drive an unsafe vehicle.

ABS and Electronic Braking control modules have not been working for 13+ months. Originally diagnosed by dealership July 2023. Been trying to get RAM / Stellantis to fix it. Been told parts are back ordered or not available due to re-engineering. Have heard there are hundreds of trucks impacted at each dealership. Why hasn’t there been a recall and why is RAM not helping me to get it resolved? Another call with them today 8/13/2024 and the dealership just needs the approval for cost for the HCU and RAM Customer Care is not responding and when they do, it takes days and no resolution.
