Common Problems & Known Issues

The 2014 Ram ProMaster, a rebadged Fiat Ducato with Chrysler's 3.6L Pentastar V6, is a capable commercial van that suffers from catastrophic engine failures tied to oil system defects and cooling issues, plus a chronically failing transmission oil cooler that can grenade the transmission if ignored.

Catastrophic Engine Failure - Spun Bearings and Cylinder Scoring

Occasional · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Sudden loss of oil pressure, Metallic knocking or rod knock at idle, Check engine light with low oil pressure codes, Complete engine seizure in severe cases, Excessive oil consumption leading up to failure
Fix: This is the nightmare scenario: spun main or rod bearings, often accompanied by scored cylinders and damaged crankshaft. Root cause appears to be inadequate oil delivery during cold starts and marginal oil filter design. Requires complete engine rebuild or replacement. Short block replacement runs 18-24 hours labor, full rebuild 25-35 hours depending on cylinder damage. Many shops recommend remanufactured long block swap.
Estimated cost: $6,500-12,000

Transmission Oil Cooler Failure and Cross-Contamination

Common · high severity
Typical onset: 50,000-90,000 mi
Symptoms: Transmission slipping or harsh shifts, Milky or strawberry-colored transmission fluid, Coolant level dropping with no visible leaks, Transmission overheating warnings, Sweet smell from exhaust (coolant burning in trans)
Fix: The internal transmission cooler inside the radiator fails, allowing coolant and ATF to mix. This destroys the 62TE transmission within days if not caught immediately. Fix requires replacing radiator, flushing entire cooling system, dropping transmission pan, replacing filter, and multiple fluid flushes. If contamination reached clutch packs, full transmission rebuild is required (12-16 hours). Preventive replacement of cooler around 60k strongly recommended. 6-8 hours for cooler replacement before transmission damage.
Estimated cost: $1,200-2,000 preventive; $4,500-7,500 with transmission damage

Transmission Shifter Linkage and BTSI Failure

Common · medium severity
Symptoms: Shifter stuck in Park, cannot move, Ignition key stuck, cannot remove from ignition, Shifter feels loose or disconnected, Gear position indicator inaccurate, Vehicle starts in wrong gear or won't start
Fix: The column shifter assembly and brake-transmission shift interlock (BTSI) solenoid are weak points. Plastic bushings wear out and solenoid fails electrically. Subject of multiple recalls but problems persist. Replacing shifter cable and bushings takes 2-3 hours; BTSI solenoid replacement 1.5-2 hours. Often both needed simultaneously at higher mileage.
Estimated cost: $350-800

Transmission Mount Collapse

Common · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Heavy clunk when shifting from Park to Drive, Vibration at idle, especially in Drive, Visible powertrain movement when accelerating/braking, Drivetrain slap when engaging throttle
Fix: The front transmission mount is inadequate for this platform's weight and torque characteristics, especially in cargo-loaded service. The rubber deteriorates rapidly and the mount collapses. Replacement is straightforward but requires supporting the transmission - 2-3 hours labor. Use heavy-duty aftermarket mounts for loaded commercial use.
Estimated cost: $300-550

Fuel Filter Clogging and Starvation Issues

Occasional · medium severity
Typical onset: 30,000-60,000 mi
Symptoms: Hard starting, especially when hot, Loss of power under load or acceleration, Surging or hesitation at highway speeds, Check engine light with lean fuel codes, No-start condition after sitting
Fix: The in-tank fuel pump assembly has an integrated filter that clogs prematurely, especially with ethanol fuel. Unlike most vehicles, there's no easily-serviceable external filter. Requires dropping the fuel tank and replacing entire pump module. 3-4 hours labor. Consider this maintenance at 50k intervals on high-mileage commercial units.
Estimated cost: $600-950

Cylinder Head Gasket Failure

Occasional · high severity
Typical onset: 80,000-140,000 mi
Symptoms: White smoke from exhaust, Coolant loss with no external leaks, Overheating under load, Rough idle or misfires, Oil contamination in coolant reservoir
Fix: The 3.6L Pentastar in this application runs hot, and head gasket failures between cylinders or into coolant passages occur. Often both heads need gaskets due to warpage. Requires removing intake manifold, exhaust manifolds, timing chains, and resurfacing heads. 16-20 hours labor for both banks. Frequently discovered during diagnosis of the catastrophic engine failures mentioned above.
Estimated cost: $3,200-5,500

Accelerator Pedal Position Sensor Failure

Occasional · medium severity
Symptoms: Electronic throttle control light illuminated, Engine runs but no throttle response, Intermittent throttle cutting out at speed, Limp mode activation, Pedal feels sticky or unresponsive
Fix: The pedal assembly sensor fails electrically, leaving you with idle-only throttle. Subject to recall but failures continue. Replacement is simple - remove two bolts and one connector - but requires OEM part and relearning procedure with scan tool. 0.5-1.0 hours labor, but expensive pedal assembly.
Estimated cost: $400-650
Owner tips
  • Change oil religiously every 5,000 miles with quality synthetic - the oil system is marginal and extended intervals will kill the engine
  • Replace transmission oil cooler preventively at 60,000 miles and check for cross-contamination monthly by inspecting both fluids
  • Install auxiliary transmission cooler if operating in hot climates or hauling heavy loads regularly
  • Budget $1,000/year for unexpected repairs after 80,000 miles - these are commercial-duty vans with passenger-car component durability
  • Keep detailed service records - resale value plummets without proof of preventive maintenance on the known issues
Avoid unless you're getting it cheap with documented oil cooler replacement and immaculate maintenance records - the engine failure risk and transmission cooler issue make this a financial time bomb for the unprepared buyer.
