A used OEM engine, transmission, or ABS module for an Infiniti runs a fraction of what the dealer charges for new, and because so many Infiniti models share drivetrain parts with each other (and with related Nissan models), used inventory is usually easier to track down than owners expect. A VQ37VHR pulled from a Q60 will often bolt into a G37 or an FX37 with the right mounts and harness, and that kind of cross-compatibility is exactly what our specialists check before quoting a part.
Where we can, we stock parts directly and get them out the same day they’re ordered. For anything not sitting in our own inventory, our nationwide network of certified recyclers and salvage yards across the US and Canada gets tapped to locate the part, verify it against your VIN, and ship it to your door or your mechanic.
That VIN check matters more with Infiniti than with a lot of brands. Between RWD and AWD drivetrains, V6 and V8 engine options, base and Red Sport trims, and two full naming conventions layered over 35 years of production, two Q50s built a year apart can need completely different parts. If you’d rather talk it through than dig through a parts diagram yourself, call 1-800-608-3868 and a parts specialist will match the part to your exact build.
A Buyer’s Guide to Getting Infiniti Used Parts
Buying a used part for a luxury vehicle carries more risk than doing it for something like a Camry, mostly because Infiniti parts aren’t sitting on the shelf at every corner parts store and mistakes are more expensive to undo. Here’s what we’d walk you through if you called us, and what we check on our end before a part ever ships.
- Pull your VIN before you start shopping. It confirms engine code, transmission type, drivetrain, and trim-level option codes in one step, which removes the guesswork that year, make, and model alone can’t settle. Every part we quote gets checked against your VIN before the order is confirmed, not after.
- Know which engine or transmission code you’re dealing with. “3.5-liter V6” describes both the VQ35DE and VQ35HR, and “7-speed automatic” can mean more than one Jatco unit depending on the model. If you can read the code off the old part or the engine block, pass it along; it’s the fastest way to rule out a mismatch before money changes hands.
- Ask whether the part needs programming. Engine control modules, some instrument clusters, and keyless entry parts on Infiniti and Nissan-built vehicles are tied to the car’s anti-theft system, NATS on most models. A used ECM will crank the engine but won’t let it start until it’s reprogrammed to your keys, and that’s a dealer or locksmith job, not a home repair. We flag which parts need this so it isn’t a surprise after installation.
- Watch for trim-specific hardware. Sport, Red Sport, AWD, and base trims often carry different suspension components, brake calipers, or differentials, even within the same model year. Two Q50s built months apart can need different parts entirely.
- Ask what “tested” actually means. A part checked for visual damage isn’t the same as one that’s been bench-tested or re-inspected right before it ships. Every part here gets inspected when it’s added to inventory and checked again within 24 hours of shipment, so the part that was tested is the part that goes out the door.
- Get the warranty and return terms in writing before you pay, not after the part shows up. We back every part with a 30-day warranty and handle returns directly if something doesn’t fit or doesn’t work.
- If you’re not confident matching parts yourself, loop in your mechanic or call a parts specialist at 1-800-608-3868. Ending up with the wrong transfer case or control module because of a mismatched trim level costs a lot more than the phone call it would have taken to avoid.
- If you’re outside the continental US, ask about shipping before you order. We deliver across the US and Canada, but timelines and freight handling for larger parts like engines and transmissions can vary, so it’s worth confirming upfront.
Most Requested Infiniti Parts
Engines
The VQ35HR and VQ37VHR V6 are the two most requested Infiniti engines by a wide margin, since together they power most of the lineup built between 2003 and 2019: G35, G37, Q40, Q50, Q60, M37, Q70, FX37, QX70, EX37, and QX50. Buyers with 2016-and-later Q50 or Q60 Red Sport models are usually after the twin-turbo VR30DDTT, while QX56 and QX80 owners need the 5.6-liter VK56DE V8. Because several of these engines cross over into Nissan models too (the 370Z shares the VQ37VHR, for instance), we’re often able to source a low-mileage unit faster than owners expect.
Transmissions
Rear-wheel-drive Infinitis built from 2009 on mostly use a version of the Jatco RE7R01A 7-speed automatic, shared in various torque ratings across the G37, M37/M56, Q40, Q50, Q60, Q70, and QX70. It’s a solid transmission overall, though valve body and torque converter wear do turn up on higher-mileage examples. The JX35 (2013) and the QX60 through the 2021 model year run a Jatco CVT that’s well known for shuddering and hesitating under light throttle, particularly on 2013-2016 units, which makes it one of the most common transmission requests we get for that vehicle. The QX60 moved to a conventional 9-speed automatic when it was redesigned for 2022.
ABS assemblies and modules
ABS actuator and module failures show up across the lineup, usually announcing themselves with an ABS or slip light and a firmer or less responsive brake pedal. Because the assembly is paired to the vehicle’s brake and stability control calibration, we match these to your VIN rather than just year and model. A Sport-trim G37’s ABS unit isn’t necessarily interchangeable with a base trim from the same model year.
Engine control modules
A used ECM is one of the trickier parts to buy for any Nissan-built vehicle, Infiniti included. These vehicles run an anti-theft system, NATS on most models, that pairs the ECM to your ignition keys, so a used module will crank the engine but won’t let it start until it’s reprogrammed by a dealer or locksmith. We confirm the exact part number and trim compatibility before shipping and tell buyers upfront that programming is required, rather than leaving that discovery for after installation.
Headlight assemblies
Xenon HID and adaptive front-lighting headlights showed up on Q50, Q60, and M/Q70 Sport and higher trims, while base trims typically ran standard halogen units. The two aren’t always interchangeable without also swapping the corresponding control module, so trim level matters as much as model year when you’re sourcing a replacement.
Instrument clusters
A used instrument cluster usually needs to be matched to your VIN and, on many model years, reprogrammed to your vehicle’s mileage and configuration once it’s installed. We flag this during the ordering process so there are no surprises about what the part needs once it arrives.
Alternators, power steering pumps, and axle assemblies
These are some of our steadiest sellers simply because they’re wear items across every Infiniti model. Power steering pump and rack issues show up especially often on higher-mileage G and M-series cars, and AWD models need axle, driveshaft, and transfer case components that differ from their RWD counterparts. Telling us RWD or AWD when you order saves a step.
