2017 RAM PROMASTER

Typical onset: 60,000-100,000 mi

Symptoms: Transmission fluid leaking from radiator area or cooler lines, Pink milky fluid in transmission pan (coolant contamination), Harsh shifting or slipping after cooler ruptures internally, Sudden transmission failure after mixing fluids

Fix: The external transmission oil cooler or its lines fail, and if the internal failure allows coolant into the trans, you're rebuilding or replacing the entire transmission. Proactive cooler replacement takes 2-3 hours; full trans R&R after contamination is 8-12 hours plus rebuild or reman unit.

Estimated cost: $400-800 for preventive cooler replacement; $4,000-6,500 for transmission replacement after contamination

Typical onset: 80,000-150,000 mi

Symptoms: Rod knock or main bearing knock at idle, worsens with load, Metal shavings in oil during changes, Low oil pressure warning intermittently or at idle, Excessive oil consumption (over 1 qt per 1,000 mi)

Fix: The high-mileage Pentastar in commercial duty can develop rod or main bearing wear, often accelerated by extended oil change intervals or towing. Needs short block replacement or full rebuild. Engine R&R in a ProMaster is 14-18 hours due to tight front-wheel-drive packaging; add machining and rebuild labor.

Estimated cost: $5,500-9,000 for short block or rebuild with labor

Typical onset: 50,000-90,000 mi

Symptoms: Heavy clunk when shifting from Park to Drive or Reverse, Vibration through floor at idle in gear, Visible sag or torn rubber in mount under vehicle, Driveline shudder during acceleration

Fix: The front-wheel-drive transaxle mount fails early, especially in cargo-loaded vans. It's a direct-bolt replacement, but access requires lifting the drivetrain slightly. Figure 2-3 hours labor.

Estimated cost: $300-500

Typical onset: 100,000+ mi

Symptoms: Rough idle or stumbling under load, Stalling in traffic or after hot soak, Hard starting when fuel tank below half, Check engine light with lean codes

Fix: The in-tank fuel pump module includes a filter that clogs with debris in commercial fleets running questionable fuel. Requires dropping the tank; 2.5-3.5 hours labor. Ram doesn't list a standalone filter service interval, but high-mileage units need it.

Estimated cost: $400-700

Symptoms: Driver or passenger seat feels loose or rocks side-to-side, Seat track disengages or binds during adjustment, Visible cracks in seat frame welds, Recall notices for seat reinforcement

Fix: Multiple NHTSA recalls address seat frame cracking and track failures that can allow seats to collapse in a crash. Dealer-only fix with reinforcement brackets or full seat replacement. Check VIN for open recalls before purchase — this is a safety-critical issue.

Estimated cost: $0 (recall repair at dealer)

Typical onset: 70,000-120,000 mi

Symptoms: Gear selector doesn't align with indicated gear (Park shows as Reverse, etc.), Cannot shift out of Park even with brake depressed, Loose or sloppy feel in column shifter, Vehicle rolls in Park on inclines

Fix: The column shift linkage bushings wear or the cable stretches, causing misalignment. Adjustment takes 0.5-1 hour; if bushings or cable are toast, figure 1.5-2 hours for parts replacement. Two recalls issued for shifter issues — verify recall compliance.

Estimated cost: $150-350 for adjustment/bushings; $0 if recall applies
