The 2017 RAM 3500 diesel exhibits multiple engine and cooling system failures. Most serious is the grid heater bolt—a component that melts or breaks from heat and vibration, then falls into the intake or cylinder, destroying the engine. Several owners report discovering the P2609 check engine code before catastrophic failure; others found engines blown after brief operation following dealer service. One owner faced a $15,000–$20,000 repair bill; another's engine failed completely at 31,600 miles just 24 miles after a dealer oil change, when a knocking sound was dismissed.
The 19V818000 recall for cooling fan defects shows a pattern of parts remaining unavailable at multiple dealerships for over a year, leaving owners unable to complete repairs. Fan clutch failures occur with belts detaching and fluid spraying, sometimes recurring within 30 days of replacement. EGR cooler and valve failures cause stalling and loss of restart capability. One owner also reports fuel filter housing leaks—identical to an earlier RAM recall issue (P65). A separate complaint documents throttle lag of 2–5 seconds with the AISIN transmission, creating hazardous merging situations. Owners express frustration that RAM has not issued a comprehensive recall for the grid heater bolt problem despite complaints spanning 2007–2024 model years.
