2018 RAM 3500 Complaints

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.

There is a recall for the brake HCU, but parts are not available. RAM won't fix. ABS warning light and traction control lights are on, and flash along with warning buzzer chime. Unacceptable. This has been going on for 4 months.

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 NHTSA 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.

The turbo actuator quit working at 103,000 miles. Loss of power. Took to Dodge dealer in Bartlesville Oklahoma to fix. I bought an extended warranty but it wouldn’t cover the cost because I have a flatbed. Out $7,500. I noticed they recalled this part on the 2015 and they need to on the 2018.

ABS PUMP Failed on 09/03/22. ABS light constantly coming on and off and dinging had it repaired on 10/21/22 had to wait for part, was charged 930.00 ABS FAILED 2ND TIME ABS Light constantly going on and off and dinging ON 1/31/25, Received recall C4B/NHTSA 24-896 on 01/13/25 in mail. Ferman Dodge of new port Richey refused to cover it, and their recall center refused to cover it or reimburse me. I had it replaced a second time on 4/11/25 had to wait for the part to come in. They are not honoring the recall which has been under investigation by NHTSA since 2021. So, I have been charged 2 time, another 957.00 and the second time the truck had not even been driven 30000 miles since last repair. So, every 30 to 40 thousand miles the abs pump fails possibly causing the brakes to malfunction. They are also saying that it was repaired on 12/05/25, Truck was not in for service on that date, see attachments,
