Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My 2023, Ram 2500 truck with a Cummins 6.7L diesel engine has a known defect with the grid heater bolt. This bolt can loosen or break off, falling into the engine and causing catastophic engine failure. This creates a suddne loss of power, espcially dangerous when towing heavy loads at highway speeds. Numerous owners have reported this issue, yet no recall has been issued. I request investigation and action to protect driver safety.”

NHTSA complaint #11685217, filed 2025-09

“Grid Heater Relay failure. From my understanding this problem is an issue across the United States. The grid heater on the 6.7L diesels has a bolt that welds itself off and can go into the intake causing an engine failure. Recently Dodge has told me that this is not covered under a power train warranty. There is no other remedy they provide other than spending $800+ for a aftermarket part to replace the OEM grid heater.”

NHTSA complaint #11623749, filed 2024-11

“Vehicle: 2023 Ram 2500 Diesel (6.7L Cummins) – approx. 36,000 miles, under factory warranty Complaint Summary: Our 2023 Ram 2500 diesel is producing visible smoke from the engine bay and a persistent ticking/clicking noise from the engine. This occurs while driving and at idle. We have video evidence of smoke coming from under the hood and recordings of the abnormal engine noise. Safety Concerns: The smoke creates a serious fire hazard and risk of mechanical failure. Engine-bay smoke can indicate an electrical short, fuel or oil leak, overheating component, or exhaust/turbo malfunction. …”
