About These NHTSA Complaints:
The NHTSA is the US gov't agency tasked with vehicle safety. Complaints can be spread across multiple & redundant categories, & are not organized by problem. See the Back button — blue bar at the very top of the page — to explore more.
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 Bosch CP4 fuel pump internally disintegrated sending metal shavings throughout the fuel system. On the highway accelerating out of a toll both without warning, the truck lost almost all acceleration power and began to shudder. There weren't any preexisting warning lamps or messages. Any time after that when accelerating up to highway speeds quickly or attempting to maintain highway speeds the truck would lose acceleration and begin to shudder. When I took it to a mechanic, they informed me the CP4 fuel pump had "grenaded" and the whole fuel system needed to be replaced. If this had happened when merging into traffic or crossing at an intersection, I could have been hit because I couldn't accelerate as needed. The manufacturer (Ram) is aware of the malfunction and has issued recalls for the 2019 and 2020 years, but not 2018s which have the same exact part. The repairs have been completed on the truck and I have copies of the invoice.

I had a warning message to service my DEF system. I had the truck checked at a RAM dealer who reported i need a new exhaust system. They had me wait a few days while they ordered parts. The message never reappeared and the truck is running fine. I dont understand why the dealer wanted me to replace my exhaust system when it apparently doesn't need one. The 2018 truck has only 18K miles on it.

Unsafe and very hesitant acceleration nearly causing accidents. Long lag time between pressing the accelerator and engine responding to throttle input.

The fuel gauge does not read the correct amount, this is all the time. This happen so far to two new 2018 vans in our fleet.
