2014 Infiniti Q50 Recalls, Issues & Maintenance

The 2014 Infiniti Q50 carries 5 open NHTSA recalls — most recently covering automated/adaptive steering and occupant classification. Owners report 6 recurring issue clusters, led by “Transmission valve body failure limiting gear shifts.” Infiniti manuals split service into Schedule 1 (severe — short trips, city traffic, extreme temperatures) and Schedule 2 (easy highway use). Most US drivers honestly belong on Schedule 1: oil every 5,000 miles. The VQ V6s that power most of the lineup are chain-driven and durable when the oil stays fresh. The two things owners skip at their peril: CVT fluid on QX50/QX60 (extended intervals are how these transmissions die) and oil discipline on the twin-turbo VR30 in Q50/Q60 Red Sport.

STEERING:AUTOMATED/ADAPTIVE STEERING

Campaign #16V430000 · Jun 13, 2016

Issue: Nissan North America, Inc.'s (Nissan) is recalling certain model year 2014-2016 Infiniti Q50 vehicles manufactured December 26, 2012, to December 11, 2015, and Infiniti Q50 Hybrid vehicles manufactured December 10, 2012, to December 17, 2015. The Direct Adaptive Steering system may experience an error at vehicle start up altering the vehicle's steering responsiveness and turning radius.

Risk: If the vehicle does not steer as the driver anticipates, there is an increased the risk of a crash.

Fix: Nissan will notify owners, and dealers will reprogram the Direct Adaptive Steering ECU software, free of charge. The recall began on August 12, 2016. Owners may contact Nissan customer service at 1-800-647-7261.

AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION

Campaign #16V244000 · Apr 26, 2016

Issue: Nissan North America, Inc. (Nissan) is recalling certain model year 2016-2017 Nissan Maxima, 2013-2016 Nissan Altima, NV200, LEAF, Sentra, and Pathfinder, 2014-2016 Nissan NV200 Taxi, Infiniti QX60, QX60 Hybrid, and Q50 Hybrid, 2014-2017 Nissan Rogue and Infiniti Q50, 2015-2016 Nissan Murano, Murano Hybrid, and Chevrolet City Express, 2014-2015 Nissan Pathfinder Hybrid, and 2013 Infiniti JX35 vehicles. In these vehicles, the front seat passenger Occupant Classification System (OCS) may incorrectly classify an adult passenger as a child or classify the seat as empty despite it being occupied. As a result, the passenger frontal air bag may be turned off and not deploy in the event of a crash.

Risk: If the passenger frontal air bag does not deploy as intended in the event of a crash, the passenger is at an increased risk of injury.

Fix: Nissan will notify their owners. Chevrolet City Express owners will be notified by General Motors. Dealers will reprogram the Air Bag Control Unit (ACU) and OCS Electronic Control Unit (ECU) in Altima, Maxima, Murano, Rogue, and Sentra vehicles, and replace the OCS ECU in LEAF, NV200, NV200 Taxi, Pathfinder, Infiniti Q50, JX35, and QX60 and Chevrolet City Express vehicles, free of charge. Interim notices were sent to owners on May 31, 2016. Owners will receive a second notice when remedy parts become available. Owners may contact Nissan customer service at 1-800-867-7669, Infiniti customer service at 1-888-833-3216 or Chevrolet customer service at 1-800-222-1020.

ELECTRICAL SYSTEM:SOFTWARE

Campaign #14V138000 · Mar 25, 2014

Issue: Nissan North America, Inc. (Nissan) is recalling certain model year 2013-2014 Altima, LEAF, Pathfinder, and Sentra, model year 2013 NV200 (aka Taxi) and Infiniti JX35 and model year 2014 Infiniti Q50 and QX60 vehicles. In the affected vehicles, the occupant classification system (OCS) software may incorrectly classify the passenger seat as empty, when it is occupied by an adult.

Risk: If the OCS does not detect an adult occupant in the passenger seat, the passenger airbag would be deactivated. Failure of the passenger airbag to deploy during a crash (where deployment is warranted) could increase the risk of injury to the passenger.

Fix: Nissan will notify owners, and dealers will update the OCS software, free of charge. The recall began on April 14, 2014. Owners may contact Nissan at 1-800-647-7261.

STEERING:ELECTRIC POWER ASSIST SYSTEM

Campaign #13V588000 · Nov 20, 2013

Issue: Nissan North America, Inc.'s (Nissan) is recalling certain model year 2014 Infiniti Q50 vehicles equipped with Direct Adaptive Steering. The affected vehicles received a power steering software version that, should the engine compartment reach freezing temperatures, the power steering software may disable the electric steering system and also may delay the engagement of the mechanical steering backup system.

Risk: The disablement of the steering systems could result in a loss of steering, increasing the risk of a crash.

Fix: Nissan notified owners and arranged to have vehicles towed to the nearest Infiniti retailer. Customers were instructed not to drive their vehicles until they were repaired. Infiniti retailers provided affected customers with loaner vehicles, while the software update remedy was applied. These services were provided at no cost to the customer. Owners may contact Infiniti at 1-800-662-6200.

POWER TRAIN:DRIVELINE:DRIVESHAFT

Campaign #24V470000 · Jun 21, 2024

Issue: Nissan North America, Inc. (INFINITI) is recalling certain 2011-2013 M56, 2012-2013 M35 Hybrid, 2014-2018 Q50, Q70 Hybrid, 2014-2019 Q70, and 2015-2019 Q70L two-wheel drive vehicles. The driveshaft can fatigue and break.

Risk: A broken driveshaft can result in a loss of drive power, or a vehicle roll away when the vehicle is in park without the parking brake applied. Both scenarios can increase the risk of a crash.

Fix: Dealers will replace the driveshaft, free of charge. Owner notification letters were mailed August 13, 2024. Owners may contact INFINITI's customer service at 1-800-662-6200. INFINITI's numbers for this recall are R24A5 and R24A7.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter

Every 5,000 mi

Every 5,000 miles under Schedule 1 (most US driving); 7,500 on the easy-use Schedule 2. VQ engines tolerate a lot but reward fresh oil with quiet chains and clean variable-timing operation. VR30 twin-turbo: treat 5,000 as the ceiling.

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 5,000 mi

Rotate with every oil change. Staggered-fitment sport models (G37S, Q60) can't rotate front-to-rear — budget rear tires accordingly.

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.

CVT Fluid (QX50 / QX60)

Every 60,000 mi

CVT-equipped models: replace fluid around 60,000 miles — sooner with towing or hot-climate city driving. Use only Nissan NS-spec CVT fluid. This is the single most skipped, most expensive-to-skip item on modern Infiniti SUVs.

Estimated cost — typical U.S. ranges

Dealer

~$360–$500

Shop

~$255–$355

DIY

~$80–$180

CVT fluid is manufacturer-specific and pricey — do NOT substitute conventional ATF.

Brake Inspection

Every 7,500 mi

Inspect pads, rotors, and lines at every service. Akebono-caliper sport packages wear pads unevenly if the slide hardware isn't serviced — have it cleaned and lubricated with pad changes.

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.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Engine Air Filter

Every 30,000 mi

Replace around 30,000 miles. Twin-intake VQ and VR engines use two filters — replace both, not just the easy one.

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.

Brake Fluid

Every 30,000 mi

Replace roughly every 30,000 miles or 2 years — Infiniti pairs it with major services. Sport models driven hard should err toward the 2-year mark.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Automatic Transmission Fluid (7/9-speed)

Every 60,000 mi

Conventional automatics (G35/G37/Q50 RWD 7-speed, QX80 9-speed): fluid service around 60,000 miles under severe use keeps shifts clean. Matic-S/Matic-D spec fluid only.

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.

Spark Plugs

Every 105,000 mi

Iridium plugs rated to 105,000 miles. On transverse VQ models (older QX60, JX35) the rear bank hides under the intake plenum — pay the labor once, at the full interval.

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.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Cabin Air Filter

Every 15,000 mi

Replace about every 15,000 miles; behind the glovebox on most models.

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.

Long-Life Coolant

Every 75,000 mi

First replacement at 75,000 miles / 5 years (Nissan blue long-life), then about every 4 years after. Genuine or NS-spec coolant only — mixing types gels.

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.

Drive Belt Inspection

Every 60,000 mi

Inspect from 60,000 miles; replace on cracking, glazing, or tensioner noise. VQ accessory belts announce their age with a cold-start chirp.

Estimated cost — typical U.S. ranges

Dealer

~$195–$235

Shop

~$135–$165

DIY

~$20–$50

DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.

Battery Test & Service

Every 25,000 mi

Test annually after year 3. Intelligent-Key and always-on telematics draw at rest — weak batteries show up first as slow push-button starts.

Estimated cost — typical U.S. ranges

Dealer

~$225–$390

Shop

~$160–$280

DIY

~$130–$250

Most auto-parts stores test and install batteries free with purchase. Skip the dealer markup.
