This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
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.
