2015 Ram Promaster City Recalls, Issues & Maintenance

The 2015 Ram Promaster City carries 4 open NHTSA recalls — most recently covering software and equipment. Owners report 4 recurring issue clusters, led by “Cooling fan failure and engine overheating.” 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.

Campaign #16E039000 · Apr 28, 2016

Issue: Chrysler (FCA US LLC) is recalling certain RAM ProMaster Trailer Light Modules, part number 68229650AB. These accessory modules were sold for installation on RAM ProMaster and ProMaster City vehicles. The Trailer Tow Lighting Control Module may have a software error on the affected vehicles and can prevent illumination of the trailer brake lights during brake actuation. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Assoc. Equipment."

Risk: Trailer brake lights that are inoperative can increase the risk of a crash.

Fix: Chrysler will mail letters to owners to try to notify the purchasers of the modules, and dealers will replace the Trailer Tow Light Control Modules, free of charge. The recall began on June 20, 2016. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is S29.

EQUIPMENT

Campaign #17V824000 · Dec 21, 2017

Issue: Chrysler (FCA US LLC) is recalling various Dodge, Chrysler, and RAM vehicles equipped with Kidde Plastic-Handle or Push Button 'Pindicator' Fire Extinguishers. A list of the affected trailer models is available at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V824-0103.pdf. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or requiring excessive force to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable. For a full list of the affected fire extinguisher models visit: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17E062-5427.pdf

Risk: If the fire extinguisher does not function properly, it can increase the risk of injury in the event of a fire.

Fix: Chrysler will notify owners instructing them to contact Kidde for a replacement fire extinguisher, free of charge. The recall began February 14, 2018. Owners may contact Chrysler customer service at 1-800-853-1403 or Kidde customer service service toll-free at 1-855-262-3540, or online at www.kidde.com and click on "Product Safety Recall" for more information. Chrysler's number for this recall is T82.

EQUIPMENT:OTHER:LABELS

Campaign #17V601000 · Sep 26, 2017

Issue: Chrysler (FCA US LLC) is recalling certain 2015-2017 RAM ProMaster City vehicles. These vehicles have incorrect information on the tire placard including incorrect vehicle capacity weight, total number of occupants, tire pressure and/or "None" designation for the spare tire size when a full size spare tire is present. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 110, "Tire Selection and Rims."

Risk: The incorrect tire placard can cause the operator to exceed the vehicle's weight capacity, or inflate the tires to an incorrect pressure, affecting vehicle handling, which can increase the risk of a crash.

Fix: Chrysler will notify owners, and dealers will replace the incorrect tire placard with a corrected one, free of charge. The recall began November 17, 2017. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is T62.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter

Every 8,000 mi

HEMI 5.7L: SAE 5W-20 every 8,000 miles per Oil Change Indicator. Pentastar 3.6L: SAE 0W-20. EcoDiesel 3.0L: full synthetic 5W-30, every 10,000 miles. Cummins 6.7L (HD): 15W-40 every 15,000 miles or 6 months.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 8,000 mi

Rotate tires every 8,000 miles. 4WD models towing or hauling regularly: rotate every 5,000 miles to even out drivetrain wear.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 8,000 mi

Inspect pads, rotors, and parking brake every 8,000 miles. Ram 1500 front pads typically last 40,000-60,000 miles under normal use; cut by 30-50% if towing heavily.

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

Dealer

~$195–$250

Shop

~$135–$175

DIY

~$20–$60

On many modern cars the filter lives inside the fuel tank and is lifetime — verify before paying for a 'service'.

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.

Automatic Transmission Fluid (ZF 8HP70 / 8HP75)

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

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Transfer Case Fluid (4WD)

Every 60,000 mi

Ram 1500 4WD: replace transfer case fluid every 60,000 miles. Use Mopar ATF+4 for the BorgWarner 44-44 transfer case.

Estimated cost — typical U.S. ranges

Dealer

~$105–$140

Shop

~$75–$100

DIY

~$15–$40

AWD/4WD vehicles only. Easy drain-and-fill on most platforms.

Differential Fluid (front + rear)

Every 60,000 mi

Front and rear axle fluid: replace every 60,000 miles, or 30,000 miles if towing 6,000+ lbs regularly. Limited-slip rears require Mopar friction-modifier additive.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.

Spark Plugs (HEMI — 16 plugs)

Every 100,000 mi

HEMI 5.7L runs two spark plugs per cylinder (16 total) — replace at 100,000 miles. Pentastar 3.6L: standard 6 plugs at 100,000 miles. EcoDiesel: glow plug inspection at 100,000.

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.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Cabin Air Filter

Every 20,000 mi

Replace cabin air filter every 20,000 miles. Behind the glove box on Ram 1500.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
