2012 Infiniti G37 Recalls, Issues & Maintenance

The 2012 Infiniti G37 carries 1 open NHTSA recall — most recently covering power window devices and controls. Owners report 4 recurring issue clusters, led by “Sunroof drain water intrusion into cabin electronics.” 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.

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.

Fatal crash history & reported problems

Occupant deaths in fatal crashes (FARS)

97 crashes 2010–2024

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number
