Worst Ram EcoDiesel Years


The 2011 Ram 1500 ranks disappointingly as the most problematic model based on NHTSA data. Many owners encountered a flawed rear axle pinion, essential for the drivetrain in rear-wheel-drive vehicles.

Despite the manufacturer’s recall campaigns to remedy the situation, numerous owners assert their concerns were overlooked. Several remained waiting for essential repairs and replacements years later.


The 2012 Ram 1500, a pre-EcoDiesel model, had its fair share of issues. The notorious ‘Hemi tick’ plagued this model, a troubling ticking sound caused by degraded exhaust manifold bolts. Owners also pointed out transmission problems leading to erratic shifting and potential failures.

More concerning, this 2012 iteration frequently exhibited engine stalling or unexpected shutdowns during driving. Despite numerous complaints, a consistent cause for these stalls remained elusive, leaving many owners frustrated and concerned about their vehicle’s reliability.


The 2014 Ram EcoDiesel was plagued by transmission issues, with owners highlighting problems such as getting trapped in a lower gear and unintentional movement even when parked. This raised safety concerns and hindered the driving experience.

Suspension problems further marred the reputation of this model year. Owners complained of alignment troubles, vibrations in the front end, air suspension failures, and sagging at the rear. Recall campaigns remained vague, not clarifying the root causes of these suspension issues, leading to confusion and dissatisfaction among vehicle owners.

Common Problems Across Various Years

When it comes to the Ram EcoDiesel lineup, these powerful trucks are a testament to American engineering. But they’ve had their share of problems over the years. Even though newer models have seen many improvements, some problems can’t seem to go away.

1. Transmission and Gear Issues

  • Stuck Gears: Some EcoDiesels unexpectedly stay in a lower gear. Imagine trying to ride a bicycle up a hill and being stuck in the highest gear – it becomes tougher, and the bike can’t speed up easily. Similarly, when a truck gets stuck in a lower gear, it affects its speed and performance.
  • Unintended Movement: Another alarming problem is the vehicle moving when it shouldn’t. There are reports of trucks drifting even when the gear selector is in park, which could be risky in many scenarios.

2. Engine Troubles

  • Hemi Tick: Named for the distinctive ticking noise it produces, the ‘Hemi Tick’ is caused by exhaust manifold bolts wearing out. Think of it as a heart having irregular beats. It doesn’t always indicate a severe issue, but it’s definitely something to be aware of.
  • Stalling: A more concerning problem is the engine stalling while driving. Just like when a runner suddenly stops mid-race, an engine stalling can be both surprising and dangerous.

3. Suspension Snags

  • Front-end Vibration: Some owners have felt their trucks vibrating excessively, especially in the front, which can be uncomfortable and distracting.
  • Air Suspension Failure: An advanced feature in many trucks, air suspension adjusts the height and feel of the ride. However, there’ve been cases where this system fails, affecting ride comfort.
  • Rear-end Sagging: Like a worn-out mattress that dips in the middle, some trucks have a rear that sags. This can affect how the truck drives and carries loads.
