Diesel fuel system on other 1500 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
Diesel fuel system complaints have a pattern of their own. Many are waiting on a recall part that isn't available yet. Others describe the truck stalling or losing power, a fuel smell in the cab, trouble right after refueling, or a diesel particulate filter that keeps clogging. Injector replacement comes up often.
What got replaced
Owners who name the part that was replaced mention the fuel pump (10 reports).
Recalls and investigations
One recall on the fuel system covers the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.
A high pressure fuel pump (HPFP) failure may introduce internal debris into the fuel system, potentially resulting in fuel starvation.

Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2018 Ram 1500 that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

Should you keep driving it?
This page can't tell you that. 0 of 52 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
