Cooling-system recall · NHTSA 23V411000

ENGINE AND ENGINE COOLING

Chrysler (FCA US, LLC) is recalling certain 2014-2019 Ram 1500 and 2014-2020 Jeep Grand Cherokee vehicles equipped with 3.0L Diesel engines. The crankshaft position sensor tone wheel may delaminate, causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall. An engine stall can increase the risk of a crash.

Dealers will update the powertrain control module software to maintain vehicle propulsion, free of charge. Interim notification letters, notifying owners of the safety risk, were mailed August 3, 2023. Some owner notification letters were mailed October 31, 2023. The remaining owner notification letters will be mailed at a future date, anticipated July 2024. Owners may contact FCA US, LLC customer service at 1-800-853-1403. FCA US, LLC's number for this recall is 66A. This recall is an expansion of recall 20V-475.

Real owner report, verbatim from NHTSA:

The contact owns a 2018 Ram 1500. The contact stated that while driving approximately 65 MPH, the vehicle stalled but was almost immediately restarted. The contact stated that several unknown warning lights were illuminated. The vehicle was driven to the destination and turned off; however, while attempting to restart, the vehicle failed to restart. The vehicle was towed to an independent mechanic to be diagnosed. The vehicle was diagnosed, and it was determined that the crankshaft position tone wheel had completely delaminated and needed to be replaced. The contact was advised by the mechanic that there was a recall for the failure. The vehicle was not repaired. The manufacturer was contacted, and the contact was informed that the VIN was not associated with NHTSA Campaign Number: 23V411000 (Engine and Engine Cooling). Several dealers were contact and provided the same information. The failure mileage was approximately 106,000.

Worth knowing: overheating is often the thermostat, water pump, or a hose, not the radiator itself. Confirm the source before you approve a radiator job.

How your cooling system works

The radiator is one piece of a loop. Knowing where it sits and what it works with is how you tell a real diagnosis from an upsell.

Enginemakes the heatRadiatorFanhot coolant outThermostatcooled coolant backWater pump
Coolant carries engine heat to the radiator, the fan pulls air through it to shed that heat, and the water pump pushes the cooled coolant back. A leak, a stuck thermostat, or a dead pump all look like “overheating” from the driver’s seat.

Found a puddle? What the color tells you

Bright green

Classic coolant leak. Find the source before it overheats.

Orange / pink

What most modern vehicles use (OAT). Same urgency as green.

Rusty brown

Old, corroded coolant. Overdue for a flush.

Milky / oily

Coolant mixing with oil. Can mean a head gasket. Serious.

What goes into a radiator replacement

The bill splits into three pieces: the radiator itself, the labor to swap it, and one to two gallons of fresh coolant with a fill-and-bleed to clear air pockets. On most vehicles the radiator sits behind the bumper cover, grille, condenser, and fans, so a tech spends two to four hours getting it out and back in. That access time, not the part price, is usually why two quotes for the same job look so different.

The 2018 Ram 1500 shipped more than one engine, and the larger one runs a little higher on both parts and access, which is why the estimate moves when you pick your engine above. National-average sites flatten that into a single number. Ask your shop to confirm the exact part for your engine before the work starts.

Estimate note: the per-engine figures are a close approximation from the make and job, refined as real local quotes come in. Treat them as a ballpark, not a guaranteed quote. The only exact number is one from a shop that has seen your car.

Frequently asked questions

  • How much does a 2018 Ram 1500 radiator replacement cost?
    A 2018 Ram 1500 radiator replacement typically runs $520 to $1,310 at an independent shop, parts and labor included. The spread comes mostly from engine and access: the part is $150 to $600, labor is two to four hours, and fresh coolant with a bleed adds $25 to $60.
  • Why does the price change with the engine?
    The 2018 Ram 1500 came with more than one engine, and the larger one usually means more coolant, tighter access, and a pricier radiator, so the job costs a little more. Sites that show one national number ignore this. Pick your engine on the estimate above for a closer figure.
  • Is it always the radiator when my Ram overheats?
    No. Overheating on this vehicle is often the thermostat, water pump, a hose, or a coolant leak rather than the radiator itself. Confirm the source with a real diagnosis before you approve a radiator job, so you are not paying to replace a part that was fine.
  • Are there recalls on the 2018 Ram 1500?
    Yes, NHTSA lists 15 recalls for the 2018 Ram 1500. Recall repairs are done free of charge at a franchised dealer for that brand, so it is worth checking your VIN before paying a shop for related work.

You deserve a fair fix.
