2017 RAM PROMASTER CITY

Typical onset: 60,000-120,000 mi

Symptoms: Excessive oil consumption (1 qt per 1,000 miles or worse), Blue smoke from exhaust on cold start or acceleration, Check engine light with misfire codes (P0300-P0304), Loss of power and rough idle

Fix: The Tigershark 2.4L suffers from inadequate piston skirt design and cylinder wall finishing that leads to ring flutter and bore scoring. Fix requires engine rebuild with updated pistons and honing, or short block replacement. Expect 18-24 labor hours for in-chassis rebuild, 12-16 for short block swap if available. Many shops recommend full longblock replacement to avoid comebacks.

Estimated cost: $4,500-7,500

Typical onset: 40,000-90,000 mi

Symptoms: Harsh shifting or shudder during 2-3 or 3-4 upshifts at low speeds, Hesitation or delayed engagement from stop, Transmission slipping or refusing to shift past 4th gear (limp mode), Whining or grinding noise during acceleration

Fix: ZF 9-speed has documented torque converter shudder, solenoid pack failures, and valve body issues. Early-stage shudder may respond to fluid/filter service with updated Mopar ZF 8&9 speed ATF (5 quarts, 2.5 hours). Advanced cases need torque converter replacement (8-10 hours) or full rebuild/replacement (12-16 hours). Stellantis has issued multiple TSBs but no extended warranty for most owners.

Estimated cost: $800-6,500

Typical onset: 50,000-100,000 mi

Symptoms: Transmission fluid leaking near front of vehicle or under radiator, Transmission overheating warning light, Pink or red fluid pooling on ground, Burnt transmission fluid smell

Fix: External cooler lines rust through or crimp fittings fail; internal radiator cooler can leak allowing coolant/ATF cross-contamination (catastrophic for transmission). External line replacement is 1.5-2.5 hours. Internal cooler failure requires radiator replacement plus complete transmission flush or replacement if coolant entered trans (add 10+ hours). Always pressure-test cooling system when diagnosing trans leaks.

Estimated cost: $350-5,000

Typical onset: 60,000-100,000 mi

Symptoms: Clunking or banging when shifting from Park to Drive/Reverse, Excessive vibration at idle, especially with A/C on, Visible sagging or tearing of rubber mount, Drivetrain lurch during hard acceleration

Fix: The front transmission mount uses a hydraulic design that fails prematurely, especially in commercial/delivery use. Replacement requires lifting powertrain slightly, 1.5-2.0 hours. Use OEM or quality aftermarket (Anchor, DEA); cheap mounts fail within 20k miles. Inspect all three engine/trans mounts while you're in there.

Estimated cost: $250-450

Symptoms: Hard starting, especially after sitting overnight, Rough idle and hesitation under load, Check engine light with fuel trim codes (P0171, P0174), Loss of power during acceleration

Fix: In-tank fuel filter/pump assembly collects debris and water more readily than typical passenger cars, likely due to fleet/commercial use patterns. Filter is non-serviceable; requires complete pump module replacement. Pump access requires dropping fuel tank or cutting access panel through floor (2.5-4 hours depending on method). If you cut access, do it right with reinforcement ring.

Estimated cost: $600-1,200

Typical onset: 80,000-140,000 mi

Symptoms: White smoke from exhaust (sweet smell), Coolant loss with no visible external leaks, Overheating or constant coolant top-offs needed, Milky oil on dipstick or oil cap, Bubbles in coolant reservoir when running

Fix: Usually secondary to cooling system neglect or transmission cooler failure contaminating coolant. Head gasket job on Tigershark 2.4L requires removing intake manifold and extensive disassembly; 10-14 hours. Always check head for warpage (common); resurface adds 2-3 hours plus machine shop time. If overheating was severe, expect to find worn cylinders requiring full engine work.

Estimated cost: $2,200-4,000
