RAM 1500 EcoDiesel
VM Motori diesel with 240 hp — same base engine as in the Jeep Grand Cherokee. Emissions scandal 2014–2016: NOx values manipulated in real-world driving, $307M FCA settlement. EGR cooler cracks from thermal fatigue, coolant escapes — fire risk. Recall 2019/2020, free repair. Software update (AEM) worsens fuel economy and drivability. Cheap on the used market due to Dieselgate fallout — fundamentally solid engine for buyers who can verify recall completion.
3.0 EcoDiesel — torque king with a scandal past
480 lb-ft from a 3.0-liter diesel makes the RAM 1500 a relaxed highway hauler. Fuel economy 22–25 mpg on the highway. But: the Dieselgate software update changed drivability. EGR cooler fire risk was recalled. With full recall documentation, a solid diesel — without it, a gamble.
Engine Weaknesses 3
EGR cooler cracks from thermal fatigue, coolant enters the engine bay — documented vehicle fires. Recall for 2014–2019 RAM 1500 EcoDiesel, free replacement by FCA.
Symptoms: Coolant loss, overheating warning, white smoke, engine bay fire in severe cases
Oil cooler fails under high temperatures, especially when towing heavy loads. Oil and coolant mix — engine damage. Primarily affects 2014–2016 EcoDiesel.
Symptoms: Milky white oil, coolant loss, overheating, power loss
EPA violation: NOx emissions in real-world driving manipulated through unauthorized software functions. ~104,000 vehicles affected (2014–2016 RAM 1500 + Jeep Grand Cherokee). $307M settlement 2019, mandatory software update AEM — afterward increased fuel consumption and altered drivability.
Vehicle Weaknesses 5
The TIPM is the central control module for the vehicle's electrical system. Moisture corrodes internal components — result: intermittent failure of fuel pump, headlights, windshield washers, door locks. Replacement required, repair rarely permanent.
Metal straps holding the fuel tank corrode through in salt belt states — tank can drop. Recall for 270,000 vehicles 2009–2012 in 20 US states. Frame design without drainage holes promotes moisture accumulation.
Optional Active Level air suspension fails in cold climates from moisture entering air lines. Lines become brittle in freezing temps, air bags lose seal. Compressor failure over $1,000 repair, complete system failure over $3,000. Conversion to coil springs is the cost-effective permanent solution.
8-speed ZF automatic shudders when the torque converter lockup clutch engages between 15–50 mph. Cause: degraded transmission fluid or clutch lining wear. RAM markets this transmission as 'Lifetime Fill' — fluid changes not recommended by dealers, which accelerates the problem.
UConnect 8.4-inch display freezes, shows blue screen, or delaminates (layers separate). 2017–2018 model years most affected: FCA switched manufacturers to cut costs. Early 2019 reverted to original supplier, issues significantly reduced.
