How Ram schedules service: Oil Change Indicator

Ram trucks use the Oil Change Indicator system to signal oil service based on driving conditions. The Ram 1500 (HEMI 5.7L, eTorque mild-hybrid, EcoDiesel 3.0L) and Ram 2500/3500 (Cummins 6.7L turbo-diesel) have markedly different intervals — the schedule below covers Ram 1500 gas. Cummins-equipped HD trucks have separate oil, fuel filter, and DEF service requirements.

POWER TRAIN:AUTOMATIC TRANSMISSION:GEAR POSITION INDICATION (PRNDL)

Campaign #25V297000 · Aug 5, 2025

Issue: Chrysler (FCA US, LLC) is recalling certain Ram 2500 and Ram 3500 vehicles equipped with a 3.5" cluster and column shifter. A software error may cause the gear selection display to be inaccurate. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 101, "Control and Displays."

Risk: An inaccurate gear selection display may mislead the driver as to what gear is actually selected, leading to unexpected vehicle movement and increasing the risk of a crash.

Fix: Dealers will update the cluster software, free of charge. Owner notification letters were mailed May 22, 2025. Owners may contact Chrysler customer service at 800-853-1403. Chrysler's number for this recall is 36C.

ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL

Campaign #25V826000 · Jan 12, 2025

Issue: Chrysler (FCA US, LLC) is recalling certain 2025-2026 Ram 1500 Pickup, Ram 2500 Pickup, Ram 3500 Pickup, Ram 3500 Cab Chassis, 4500 Ram Cab Chassis, and Ram 5500 Cab Chassis vehicles. A software error may cause the instrument panel cluster display to be blank. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard numbers 135, "Light Vehicle Brake Systems," 105, "Hydraulic and Electric Brake Systems," and 102, "Transmission shift lever sequence, starter interlock, and transmission braking effect."

Risk: An instrument panel display that does not show critical information, such as warning lights or gear selection, increases the risk of a crash.

Fix: Dealers will inspect and update the instrument panel software or replace the instrument panel cluster, as necessary, free of charge. Owner notification letters were mailed December 18, 2025. Owners may contact Chrysler customer service at 800-853-1403. Chrysler's numbers for this recall are B4C and B8C. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov beginning December 4, 2025.

AIR BAGS: AIR BAG/RESTRAINT CONTROL MODULE

Campaign #25V882000 · Dec 18, 2025

Issue: Chrysler (FCA US, LLC) is recalling certain 2025 Ram 2500 Pickup, 3500 Pickup, 3500 Cab Chassis, 4500 Cab Chassis, and 5500 Cab Chassis trucks. A software error in the occupant restraint controller module may cause the driver's side air bag and/or seat belt pretensioner not to deploy in a crash and disable the electronic stability control (ESC) system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard numbers 208, "Occupant Crash Protection" and 126, "Electronic Stability Control Systems."

Risk: Driving with a disabled electronic stability control system increases the risk of a crash. Additionally, a driver's side air bag or seat belt pretensioner that does not deploy increases the risk of injury in a crash.

Fix: Dealers will update the occupant restraint controller module software, free of charge. Owner notification letters were mailed January 15, 2026. Owners may contact Chrysler customer service at 800-853-1403. Chrysler's number for this recall is C3C. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on December 19, 2025.

EXTERIOR LIGHTING:BRAKE LIGHTS

Campaign #26V059000 · Feb 2, 2026

Issue: Chrysler (FCA US, LLC) is recalling certain 2024-2026 Jeep Wagoneer S, 2025-2026 Ram 1500 Pickup, Ram 2500 Pickup, Ram 3500 Pickup, Ram 3500 Cab Chassis, Ram 4500 Cab Chassis, Ram 5500 Cab Chassis, and 2026 Jeep Cherokee vehicles. Due to an improperly designed trailer tow module, the trailer lights may fail to illuminate and the trailer brakes may fail.

Risk: Trailer brake lights and turn signals that do not illuminate reduce visibility to other drivers, increasing the risk of a crash. Additionally, trailer brakes that fail increase the risk of a crash.

Fix: Dealers will replace the trailer tow module, free of charge. Owner notification letters were mailed beginning March 17, 2026. Owners may contact FCA US, LLC customer service at 1-800-853-1403. FCA US, LLC's number for this recall is 03D. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on February 10, 2026.

A software error may cause the instrument panel display to fail. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standards numbers 102, "Transmission Shift Position Sequence," 105, "Hydraulic and Electric Brake Systems," 108, "Lamps, Reflective Devices, and Associated Equipment," 126, "Electronic Stability Control Systems for Light Vehicles," 135, "Light Vehicle Brake Systems," 138, "Tire Pressure Monitoring System," and/or 208, "Occupant Crash Protection."

~$60

DIY

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

⛽

Fuel Filter (EcoDiesel + Cummins)

Every 30,000 mi

EcoDiesel 3.0L: dual fuel filters (under hood + frame-mounted) replace every 30,000 miles. Cummins 6.7L: replace at 30,000 miles or sooner if water-in-fuel light triggers.

Estimated cost — typical U.S. ranges

Important maintenance

Keeps your vehicle running smoothly and efficiently

💨

Engine Air Filter

Every 40,000 mi

Replace engine air filter every 40,000 miles. Trucks driven on construction sites or unpaved roads should inspect at every oil change.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Every 60,000 mi

Severe service (towing, plowing): replace ATF every 60,000 miles. Normal: 120,000 miles. Use Mopar ATF+4 — substitutes cause harsh 3-4 and 5-6 shifts.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Dealer

~$150–$195

Shop

~$105–$135

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

🌡️

MS-12106 Coolant (Mopar HOAT)

Every 50,000 mi

Mopar HOAT (purple): first change at 100,000 miles or 5 years, then every 50,000 miles. EcoDiesel uses a different OAT formulation — do not mix.
