DT (5th gen, 2019+) · 2019–present
3.0 EcoDiesel V6 · 260 hp · 3.6 Pentastar V6 eTorque · 305 hp · 5.7 HEMI V8 · 395 hp · 5.7 HEMI V8 eTorque · 395 hp
Known problems
- Critical
3.0 EcoDiesel EGR cooler fire risk and reliability
Symptoms: coolant loss and, in the recalled fault, an EGR cooler that can crack and create a fire risk; also high-pressure fuel pump and oil-cooler concerns
What to do: The 3.0 EcoDiesel was recalled for an EGR cooler that can fail and cause an under-hood fire, and it has a record of costly fuel-system and oil-cooler problems. Confirm any recall is completed and budget carefully; many buyers avoid this engine for these reasons.
- Critical
5.7 eTorque powertrain control module stall risk (2021)
Symptoms: an engine stall from an incorrect fuel-mixture condition caused by a powertrain control module software fault
What to do: Ram recalled 2021 Ram 1500s with the 5.7 HEMI eTorque for this software fault. Confirm the recall has been completed by VIN.
- Critical
ABS control module software disables stability control
Symptoms: the electronic stability control system silently disables itself due to an ABS control module software fault, with no obvious warning to the driver beyond a dash light
What to do: Ram recalled 2019 and 2021-2024 trucks for this software fault. Confirm the recall (a software update) has been completed by VIN — driving with stability control disabled is a real crash-risk increase, especially in slippery conditions.
- Worth watching usually from 25,000 mi (40,000 km)
3.6 Pentastar rocker-arm / lifter tick
Symptoms: ticking noise and occasional misfire, sometimes with a rocker-arm or lifter fault code
What to do: Some Pentastar V6 engines develop a tick from a worn rocker arm or lifter. Have a persistent tick with a misfire diagnosed rather than ignored, since a failed rocker can damage the valvetrain. Regular correct-spec oil changes help.
- Worth watching usually from 31,000 mi (50,000 km)
5.7 HEMI lifter and camshaft failure ('HEMI tick')
Symptoms: a persistent metallic tick or knock, rough running or misfire, and a check-engine light; often the roller lifter fails and wipes a camshaft lobe
What to do: A steady tick on the 5.7 HEMI can be a failing lifter that damages the camshaft, an expensive repair that usually means replacing the cam and all lifters. Don't ignore a persistent tick with a misfire; use the specified oil, keep changes on time and avoid long idling.
- Worth watching usually from 35,000 mi (56,000 km)
5.7 HEMI exhaust manifold bolts (carryover)
Symptoms: a ticking or popping exhaust noise, especially on cold start, from exhaust manifold bolts that loosen or shear as the manifold warps under heat cycling
What to do: The same manifold-bolt wear that affects earlier HEMI-engined Ram trucks continues to be reported on this generation. Have a ticking exhaust noise checked before assuming it's the lifter 'HEMI tick' — a manifold-bolt fix is far cheaper.
- Worth watching usually from 37,000 mi (60,000 km)
3.6 Pentastar oil filter / cooler housing leak
Symptoms: oil pooling in the valley between the cylinder heads and dripping off the back of the engine, easily mistaken for a rear main seal leak
What to do: The Pentastar V6's plastic oil-filter/cooler housing commonly cracks or leaks at its seals. If you see oil in the engine valley or dripping off the rear of the block, have the housing replaced — an upgraded aluminium housing is the durable fix.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | follow the oil-life monitor; halve for towing, heavy loads or short-trip use — use the specified viscosity |
| Cabin filter | every 19,000 mi (30,000 km) | — |
| Air filter | every 28,000 mi (45,000 km) | — |
| 8-speed automatic fluid (8HP) Important | every 75,000 mi (120,000 km) | service earlier if used for towing or in severe conditions |
| Spark plugs (petrol) | every 99,000 mi (160,000 km) | the 5.7 HEMI has two plugs per cylinder; not applicable to the diesel |
| Brake fluid Important | every 36 months | — |
| Timing chain inspection | — | the HEMI and Pentastar are chain-driven — inspect for noise rather than on a fixed interval |
Classic (DS body, sold alongside DT) · 2019–2024
3.6 Pentastar V6 · 305 hp · 5.7 HEMI V8 · 395 hp
Known problems
- Worth watching usually from 31,000 mi (50,000 km)
5.7 HEMI lifter and camshaft failure ('HEMI tick')
Symptoms: a persistent tick or knock, rough running or misfire and a check-engine light from a failing lifter that can wipe a cam lobe
What to do: The 'HEMI tick' from lifter and camshaft failure applies to the Classic's 5.7 V8 as well. Address a persistent tick with a misfire promptly; use the specified oil, keep changes on time and avoid extended idling.
- Worth watching usually from 37,000 mi (60,000 km)
3.6 Pentastar oil filter / cooler housing leak
Symptoms: oil collecting in the valley between the heads and dripping off the rear of the engine
What to do: The Pentastar plastic oil-filter/cooler housing commonly leaks. If oil appears in the engine valley or at the back of the block, replace the housing — an aluminium replacement is the lasting fix.

DS (4th gen, 2009–2018) · 2009–2018
3.0 EcoDiesel V6 (2014+) · 240 hp · 3.6 Pentastar V6 (2013+) · 305 hp · 3.7 V6 (PowerTech, 2009-2012) · 215 hp · 4.7 V8 (PowerTech, 2009-2013) · 310 hp · 5.7 HEMI V8 · 395 hp
Known problems
- Critical
3.0 EcoDiesel EGR cooler fire risk (2014-2018)
Symptoms: coolant loss and, in the recalled fault, an EGR cooler that cracks and lets pre-heated vaporised coolant reach the intake manifold, where it can ignite
What to do: Ram recalled 2014-2019 Ram 1500 and 1500 Classic trucks with the 3.0 EcoDiesel for this fault. Confirm the recall has been completed by VIN — this is a genuine under-hood fire risk, not just a coolant-loss nuisance.
- Critical
3.0 EcoDiesel crankshaft sensor and high-pressure fuel pump stall risk (2014-2018)
Symptoms: a sudden engine stall or unexpected loss of drive power, from a crankshaft position sensor tone wheel that delaminates and desynchronizes injector/cam timing, or a high-pressure fuel pump that fails and contaminates the fuel system
What to do: Ram recalled 2014-2019 Ram 1500 EcoDiesels twice for these separate but related stall risks — a crankshaft sensor fault and a high-pressure fuel pump failure. Confirm both recalls have been completed by VIN; either can stall the engine without warning.
- Critical usually 40,000–90,000 mi (64,000–145,000 km)
Electric power steering assist loss (2013-2018)
Symptoms: a sudden loss or big reduction of power steering assist, making the wheel heavy to turn — most noticeable at parking speed — sometimes returning after the ignition is cycled
What to do: The electric power steering introduced with the 2013 refresh has a well-documented pattern of assist loss, from contamination or a fault on the EPS control circuit board. A factory recall covers only a narrow band of 2015-2016 trucks built in a specific window — confirm that one by VIN, but don't assume an unaffected VIN is in the clear: have any steering-assist loss diagnosed regardless, since a heavy, hard-to-turn wheel at low speed is a real safety issue.
- Critical usually 50,000–99,000 mi (80,000–160,000 km)
TIPM fuel pump relay failure
Symptoms: random stalling while driving, intermittent failure to start, and other electrical gremlins (wipers, interior lights) traced to the Totally Integrated Power Module's internal fuel pump relay
What to do: A truck that stalls unpredictably or won't reliably start, with no consistent fault code, points to a failing TIPM fuel-pump relay — extremely common on this generation. Have a shop test the relay directly rather than chasing the fuel pump itself; a remanufactured or new TIPM is the usual fix. Don't ignore intermittent stalling — it can happen at any speed.
- Worth watching usually from 25,000 mi (40,000 km)
3.6 Pentastar rocker-arm / lifter tick (2013-2018)
Symptoms: ticking noise and occasional misfire, sometimes with a rocker-arm or lifter fault code
What to do: Some Pentastar V6 engines in this generation develop a tick from a worn rocker arm or lifter. Have a persistent tick with a misfire diagnosed rather than ignored, since a failed rocker can damage the valvetrain. Regular correct-spec oil changes help.
- Worth watching usually from 25,000 mi (40,000 km)
5.7 HEMI exhaust manifold bolts breaking
Symptoms: a ticking or popping exhaust noise, especially on cold start or under load, from exhaust manifold bolts that loosen or shear as the manifold warps under heat cycling
What to do: A ticking exhaust noise is often mistaken for the lifter 'HEMI tick' but is a separate, cheaper fix — broken or loose exhaust manifold bolts letting the manifold warp and leak. Have the manifold bolts inspected and replaced (updated bolts and gaskets are available) before the leak worsens or damages nearby wiring.
- Worth watching usually from 30,000 mi (48,000 km)
Air suspension (Quadra-Lift) faults (2013-2018, optional equipment)
Symptoms: the truck sitting unevenly or lower than normal, a compressor that runs excessively or won't build pressure, or a ride-height warning light
What to do: Trucks ordered with the optional Quadra-Lift air suspension (Laramie/Longhorn trims) can develop air-line leaks or a failing compressor. Have the system diagnosed at the first sign of uneven ride height rather than waiting for a full failure, which can leave a corner resting on its bump stop.
- Worth watching usually from 31,000 mi (50,000 km)
5.7 HEMI lifter and camshaft failure ('HEMI tick')
Symptoms: a persistent metallic tick or knock, rough running or misfire, and a check-engine light; often a roller lifter fails and wipes a camshaft lobe
What to do: A steady tick on the 5.7 HEMI can be a failing lifter that damages the camshaft — an expensive repair that usually means replacing the cam and all lifters. Don't ignore a persistent tick with a misfire; use the specified oil, keep changes on time and avoid long idling.
- Worth watching usually from 37,000 mi (60,000 km)
3.6 Pentastar oil filter / cooler housing leak (2013-2018)
Symptoms: oil pooling in the valley between the cylinder heads and dripping off the back of the engine, easily mistaken for a rear main seal leak
What to do: The Pentastar V6's plastic oil-filter/cooler housing commonly cracks or leaks at its seals on these trucks too. If you see oil in the engine valley or dripping off the rear of the block, have the housing replaced — an upgraded aluminium housing is the durable fix.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | follow the oil-life monitor; halve for towing, heavy loads or short-trip use — use the specified viscosity |
| Diesel exhaust fluid (DEF) refill | every 10,000 mi (16,000 km) | 3.0 EcoDiesel only — the engine derates and eventually won't restart if DEF runs out |
| Diesel fuel filter Important | every 15,000 mi (24,000 km) | 3.0 EcoDiesel only |
| Cabin filter | every 19,000 mi (30,000 km) | — |

Lab-cycle figures, each shown with the cycle it was measured under — the same car under EPA, WLTP, NEDC or JC08 can differ by up to 20%. Real driving always falls short of the declared figure: roughly 10–20% on an EPA rating, 15–30% on a WLTP or NEDC one. That gap is normal, not a fault.

Frequently asked
What are the most common Ram 1500 problems?
The faults reported most often are: 3.0 EcoDiesel EGR cooler fire risk (2014-2018); 3.0 EcoDiesel crankshaft sensor and high-pressure fuel pump stall risk (2014-2018); Electric power steering assist loss (2013-2018). Symptoms, the mileage each appears at and what to do about it are all above.
How often does the Ram 1500 need servicing?
Engine oil & filter change — every 7,000 mi (12,000 km) or 12 months. The full published schedule is above; your car's own service book always takes precedence.
What is the real fuel consumption of the Ram 1500?
The manufacturer declares 24 mpg (9.8 L/100 km) combined for the 3.0 EcoDiesel V6 under the EPA cycle. Real driving falls short of any lab figure — roughly 10–20% on an EPA rating, 15–30% on a WLTP or NEDC one — and that gap is normal.
Where does this data come from?
