Ram 1500 2013–2018Common problems, reliability & repair costs

Symptoms: A sharp ticking on cold start that quiets as the engine warms up, eventually a steady exhaust leak and a sulfur/exhaust smell. Caused by the original manifold bolts shearing off from repeated heat cycling.

Fix: Remove the manifold, drill out and extract the broken bolts, re-tap or heli-coil the holes, new bolts/studs and gaskets. Cost climbs fast if a manifold is warped/cracked and needs machining or replacement, and if both sides are done.

Symptoms: Coolant loss with no obvious leak, overheating, white exhaust smoke or unusual exhaust noise. The EGR cooler develops micro-cracks that let coolant into the hot exhaust path — linked to a small number of underhood fires.

Fix: Covered by FCA's 2019 EGR-cooler recall on ~160,000 EcoDiesel trucks — get it done free at a dealer if not already completed. Out of recall coverage, EGR cooler replacement is a labor-heavy job, and failures have recurred even after the recall part on some trucks.

Symptoms: Oil and coolant cross-contamination, oil leaks, milky coolant or oily residue. Left unaddressed it can starve the engine of oil and kill it. Unlike the EGR cooler, the oil cooler was never recalled despite high failure volume.

Fix: Oil cooler / cooler-housing replacement, deep in the valley of the engine and labor-intensive. If contamination already damaged the engine the bill is far higher. A documented oil-cooler replacement on a used EcoDiesel is a plus, not a red flag.

Symptoms: Truck sits low or unevenly after sitting, a service-suspension warning, the compressor running constantly or not at all. Rubber air springs crack and lines go brittle with age; the compressor then overworks and burns out.

Fix: Replace failed air spring(s), the compressor, or the valve block — often more than one as the system ages. Some owners convert to a conventional coil-spring kit to be done with it. Cumulative air-system spend can climb well past these numbers.

Symptoms: Erratic electrical gremlins: fuel pump running after shutdown, no-start, windows or wipers acting on their own, random horn, dead accessories. The TIPM is the truck's central power/fuse module, so failures present in many ways.

Fix: Diagnose to confirm it's the TIPM and not a simpler fault, then replace and reprogram the module (or repair the failed circuit). Genuine TIPM failure is a known weak point on FCA vehicles of this era.

Symptoms: Hard or jerky shifts, a pause when moving from Park to Drive/Reverse, occasional slipping. Often fluid-related but can indicate valve-body wear or the A-clutch pressure plate.

Fix: Start with a proper fluid and filter service (the cheap end). Persistent issues may need a valve body or internal clutch repair, and a full rebuild/replacement is the worst case. Servicing the 'lifetime' fluid on schedule heads off most of this.

Tools: Socket set + torque wrench, Ratcheting wrenches, Drain pan, New O-rings / cooler gaskets

1. Let the engine cool, then drain the coolant (the housing carries an oil cooler).
2. Remove the intake/air components and anything blocking access to the housing in the valley.
3. Unbolt the cracked plastic housing and clean the mating surface thoroughly.
4. Install the upgraded aluminum housing with new gaskets/O-rings, torquing bolts to spec.
5. Refill coolant, run the engine, and check for oil and coolant leaks.

Tools: Flat screwdriver (airbox clips)

1. Unclip the engine airbox lid, lift it, and pull the old panel filter.
2. Wipe out the airbox and drop in the new filter seated flat in its frame.
3. For the cabin filter, open the glovebox and release the stops to drop it down.
4. Slide out the old cabin filter and insert the new one with the airflow arrow correct, then reseat the glovebox.

Tools: Floor jack + jack stands, Torx/socket set, Fluid pump (fill from below), Drain pan + scale or measuring setup

1. With the truck level and the fluid at the correct temperature, remove the fill plug.
2. Drop the pan or remove the drain plug and let the old fluid out; replace the filter integrated in the pan.
3. Reinstall the pan/filter with a new gasket, torqued to spec.
4. Pump in the correct ZF-spec fluid through the fill port until it streams out at the right temperature.
5. Cycle through the gears, recheck level, and confirm no leaks.
