It has been 3 years of our ABS failing due to a Brake HCU not being replaced. Now the engine light comes on due to issues with the Electronic Braking System. We cannot use this to travel due to the cruise control going out as soon as the ABS light goes on which is every 5 minutes. Why is this allowed to be on recall but ‘ no fix has been determined’?!!!! We need answers.

vehicle intermittently sets check engine light for code p0871 and causes truck to go into a limp mode and a 4th gear start only. I have notice online this issue going on for years on Ram trucks with no recall. The light will go off and store code but dealers will not address if light is not on. If truck set code with not at moment effect I could see, however what happens can occur during driving and feel it creates an unsafe condition.

On May 3, 2025, while driving my 2018 RAM 2500 with approximately 46,000 miles, the check engine light came on and the engine immediately experienced a significant loss of power. The vehicle entered a limp mode condition, drastically reducing speed and acceleration. I was forced to pull into a nearby business as the truck could not maintain safe highway speeds, creating a traffic hazard and contributing to congestion. The vehicle was diagnosed by a repair facility as having a failed turbo actuator, a critical component in regulating turbo boost and engine power delivery. After researching this issue, I have found numerous similar complaints and reports from other RAM truck owners on various owner forums and websites, indicating this may be a recurring and potentially widespread defect in these vehicles. Given that this failure occurred at relatively low mileage, caused a hazardous driving condition, and seems to be a commonly reported problem, I believe this issue warrants investigation by the federal safety agency for potential safety risks and manufacturer accountability. No injuries or property damage occurred, but the incident posed a significant safety risk to myself and other drivers.

On or about [XXX] my Ram 3500 showed a check engine light indicating to service the HCU/ABS system. After researching this I discovered there was a problem with the HCU/ABS in the Ram 3500. At the time there was no recall for the part. I found the part and replaced the part. On or about 1/25 I received a recall notice from the manufacturer. I proceeded to their website and submitted the required documents for reimbursement. I was promptly denied reimbursement: "Dear Mr. [XXX] , Good day! We understand that this was not the decision that you were hoping for, and we apologize for that, but that is the decision of the company based on the information provided. There is no installation cited and it is not eligible for reimbursement. We look forward to the chance to assist you in the future, and we thank you for being a Ram customer. Regards, Therie Ram Customer Care " I called and talked to several representatives, however, they still will not reimburse for the part. I explained to the representative that I did the work myself and indicated this on the reimbursement form (did the work myself was a selection). I explained this repair was a safety issue, dealers were charging $1500-$2000 to do the repair, and the time of this issue the replacement part was on a nationwide shortage. The dealer could give me no timeframe on when they could secure the part. Due to these reasons I kept looking until I finally found the part and did the repair myself. I provided proof of purchase from the dealer, credit card statement showing payment and offered to take a picture of the old part and installed part side by side as I still have the old part. They still denied reimbursement. Is there anything you can do? It doesn't seem fair that the manufacturer of a defective part gets to make the rules for reimbursement and can deny any disputes the consumer has with their decisions. It seems the federal safety agency should have a say in this. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
