Common Problems & Known Issues

The 2015 Ram ProMaster is a rebadged Fiat Ducato commercial van with the Pentastar 3.6L V6 and a 62TE transmission. It's susceptible to catastrophic engine failure and transmission cooler issues that can leave you stranded—both expensive repairs that typically hit before 100,000 miles.

Catastrophic Engine Failure (Cylinder Dropout)

Occasional · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Sudden loss of power and rough running, Check engine light with misfire codes (often cylinders 2, 3, or 5), Metallic rattling or knocking from engine bay, Oil consumption increases dramatically before failure, White smoke from exhaust indicating coolant intrusion
Fix: Head gasket failure leads to coolant in cylinders, washing cylinder walls and scoring pistons. Often requires complete short block replacement or full rebuild including pistons, rings, bearings, and head work. 20-30 hours labor at a shop familiar with the platform. Some cases need crankshaft replacement if debris circulated.
Estimated cost: $6,000-12,000

Transmission Oil Cooler Failure

Common · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Transmission fluid mixing with coolant (strawberry milkshake in reservoir), Transmission slipping or delayed engagement, Overheating transmission temp warnings, Loss of both coolant and ATF simultaneously, Sudden transmission failure after cooler breach
Fix: The internal transmission cooler in the radiator fails, cross-contaminating fluids and destroying the transmission. Requires radiator replacement, transmission rebuild or replacement, complete fluid flush of both systems. 12-18 hours labor. Catching it early (milkshake coolant) saves the trans; ignoring it means full replacement.
Estimated cost: $4,500-8,500

Transmission Shift Linkage Failure

Common · medium severity
Typical onset: 40,000-80,000 mi
Symptoms: Shifter moves but transmission doesn't change gears, Cannot shift out of park despite brake depressed, Gear indicator doesn't match actual gear position, Shifter feels loose or disconnected, Vehicle rolls in park (dangerous)
Fix: Plastic bushings and cable ends in the column shift mechanism wear out prematurely, especially on work vans with frequent shifting. Replace entire shift cable assembly and linkage components. 2-4 hours labor. Two separate NHTSA recalls address this, but failures continue outside recall scope.
Estimated cost: $400-800

Transmission Mount Collapse

Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Loud clunk when shifting from park to drive or reverse, Vibration through chassis during acceleration, Visible transmission sag when inspected from below, Harsh engagement into gear, Shifter difficulty or grinding noise during gear changes
Fix: The rear transmission mount deteriorates rapidly under the weight and torque of the 62TE. Rubber separates from metal bracket. Replace mount (upgraded aftermarket versions available). 1.5-2.5 hours labor. Check engine mounts simultaneously as they often fail together.
Estimated cost: $250-500

Fuel Filter Clogging and Fuel System Contamination

Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Hard starting, especially when cold, Loss of power under load or at highway speeds, Engine stumbling or hesitation during acceleration, Stalling at idle after running, Check engine light with lean fuel codes
Fix: Factory fuel filter is undersized for commercial use and clogs prematurely, especially with poor fuel quality. Located in-tank with pump assembly, making it labor-intensive. Replace entire pump/filter assembly. 3-4 hours labor. Some owners install inline secondary filter for prevention.
Estimated cost: $600-1,200

A/C System Failure (Compressor and Condenser)

Occasional · low severity
Typical onset: 70,000-120,000 mi
Symptoms: No cold air from vents, Compressor clutch not engaging, Loud squealing or grinding from compressor, Intermittent cooling that fails when hot outside, Refrigerant leaks at condenser (mounted low, rock damage common)
Fix: Compressor failures send debris through system requiring full flush. Condenser location makes it vulnerable to road damage. Replace compressor, condenser, receiver-drier, flush lines, evacuate and recharge. 4-6 hours labor. NHTSA recall exists for some A/C issues but doesn't cover mechanical failures.
Estimated cost: $1,200-2,000
Owner tips
  • Check coolant reservoir weekly—catching transmission cooler failure early (milkshake appearance) saves $4,000+ in transmission damage
  • Change transmission fluid every 30,000 miles (not 'lifetime' as Chrysler claims) to extend 62TE life
  • Inspect transmission and engine mounts annually; replacing them proactively at 60k costs $500 vs. dealing with damage from broken mounts
  • Use top-tier fuel and consider adding secondary inline fuel filter if using van commercially
  • Monitor oil consumption closely after 50,000 miles—sudden increase signals impending head gasket failure
Buy only if you need the cargo space and can afford to set aside $5,000 for likely engine or transmission work before 120,000 miles—not a reliable long-term commercial platform compared to Ford Transit.
