The 2014 Ram 2500 demonstrates recurring electrical and engine-control defects that strike early. Unintended acceleration to 80+ mph occurs within days of purchase, with severe brake strain; throttle lag creates 2–3 second delays in acceleration response from stops—dangerous during merging and passing. Some engines stall unexpectedly at traffic lights or low speeds.
Diesel exhaust odor persistently enters the cabin, particularly during defrost and regeneration, despite multiple dealer and independent shop visits. Owners report Chrysler denied parts replacement and advised simply turning off the defrost.
Mechanical failures escalate with mileage: coolant breakdown begins around 60–100K miles, plugging heater cores and EGR coolers; water pump bearings seize, breaking impeller shafts and leaving trucks stranded mid-tow. The 6.4L Hemi develops wrist-pin knockers within 25,000 miles—total engine loss. A 6.7L intake-manifold bolt can loosen and enter the #6 cylinder, causing catastrophic failure if undetected.
Turbo-actuator noise and failure occur at or below 100,000 miles. Fan shrouds are sucked into cooling fans, destroying radiators.
Recall-related issues compound the pain: replacement parts for Campaigns 14V635000, 17V562000, and 67A have been unavailable for extended periods; owners who prepaid for now-recalled components have had reimbursement claims denied without explanation, and Chrysler customer service has been unresponsive.
Failure modes owners describe
Unintended acceleration (electronic throttle malfunction)
Vehicle accelerates to 50–80+ mph on its own without driver input, with engine RPMs climbing immediately upon placing vehicle in Drive. Brake effort required is severe; brakes smoke from strain. A 'SERVICE ELECTRONIC SPEED CONTROL' message appears on the instrument cluster. Occurs early in vehicle life (under 11,000 miles).
When: Under 5,000–10,650 miles; days to weeks after purchase
Symptoms owners cite: Uncontrolled acceleration to 50–80+ mph without driver pedal input; High RPMs held even with foot off accelerator; Vehicle lunges forward repeatedly after braking to stop; Severe brake strain and smoking; SERVICE ELECTRONIC SPEED CONTROL warning displayed
Codes mentioned: SERVICE ELECTRONIC SPEED CONTROL message
Throttle lag / dead pedal (acceleration hesitation)
When accelerating from a stop or reapplying throttle after brief pedal release, the truck does not respond for 2–3 seconds. Owners report this occurs during merging, leaving traffic signals, and passing maneuvers. Some incidents include engine stalling and multiple near-misses from being rear-ended. Problem present from day one in some cases.
When: Throughout vehicle life; consistent issue from new on some trucks
Symptoms owners cite: 2–3 second delay in throttle response after pedal reapplication; Loss of speed during traffic merging and passing situations; Engine stalling when slightly depressing throttle after brief release; Multiple near-miss collision incidents; Consistent hesitation from initial ownership
