2012-2013 Ram 2500: Fuel System and Steering Nightmares
The 2012 Ram 2500 suffered from dangerous fuel heater connector issues that could overheat, creating a significant fire hazard. This problem was serious enough to prompt a recall, but many owners reported difficulties getting permanent fixes.
Steering problems plagued both the 2012 and 2013 models, with drivers reporting sudden steering failures, especially after driving over bumps or while towing. These issues typically emerged around 23,750 miles, making them particularly frustrating for owners who had barely broken in their trucks.
The 2013 model year is arguably one of the worst in Ram 2500 history, with a staggering 16 recalls and hundreds of owner complaints. Engine problems were particularly severe, with owners reporting unexpected power loss and failures in critical components like the diesel particulate filter and turbo unit, typically occurring around 28,321 miles.
“The steering suddenly became unresponsive after hitting a small pothole. I nearly crashed into oncoming traffic. After three repair attempts, the problem still persists.”
Perhaps most concerning was the infamous “death wobble” that affected many 2013 models. This violent vibration occurred at highway speeds after hitting bumps or potholes, with owners describing it as severe enough to blur vision and force them to pull over. The average failure mileage for this issue was approximately 35,100 miles.
2014-2016 Ram 2500: Engine and Control System Failures
The 2014 Ram 2500 continued the troubling reliability trend with serious engine problems. The 6.7L Cummins diesel engines suffered from a dangerous fault with the intake plenum bolt. This bolt could loosen and break off, potentially being ingested by the #6 cylinder and causing catastrophic engine failure. Repair costs for this issue often exceeded $6,000.
Additionally, 2014 models experienced systemic defects causing overheating and coolant breakdown. These problems led to expensive repairs including thermostat failures, heater core clogs, and EGR cooler blockages.
The 2015 model year Ram 2500 accumulated 281 complaints and 15 recalls. Owners reported excessive vibrations at high speeds (the “death wobble”) and broken exhaust manifold bolts causing disturbing ticking noises. These manifold issues typically appeared around 27,847 miles.
For the 2016 Ram 2500, with over 300 consumer complaints and 13 recalls, the most concerning issues involved vehicle speed control problems. The ABS and traction control systems would malfunction simultaneously, compromising braking efficiency, cruise control, and 4-wheel drive capabilities—critical safety features, especially for winter driving.
Warning: If you’re considering a 2014-2016 Ram 2500 with the 6.7L Cummins diesel engine, a thorough inspection by a diesel specialist is absolutely essential. Listen for ticking noises from the exhaust manifold and check for coolant leaks or overheating history.
2018 Ram 2500: The Most Problematic Year
The 2018 Ram 2500 stands out as possibly the least reliable model year, accumulating over 1,000 owner complaints and seven recalls. The most prevalent issues involved the service brakes, particularly failures in the Anti-lock Braking System (ABS).
Owners reported malfunctioning ABS and traction control warning lights that would flash erratically, often resulting in complete loss of ABS functionality. These problems typically appeared very early in the vehicle’s life, around 1,024 miles on average.
In numerous cases, the Hydraulic Control Unit (HCU) was found to be defective, requiring expensive replacement. These brake system failures pose serious safety risks, especially when towing heavy loads or driving in adverse conditions—precisely the situations where a heavy-duty truck should excel.
