At the dealership they’re asking for a Transmission fluid exchange with my Infiniti Q50 at 60k miles. As far I know this was not done before but I got the car At 15k miles. Needed or dealership upcharge?
70k Miles. One Owner. And super clean interior and exterior. Negotiated for 6.3K. don’t know where to start honestly. Would love to start building towards to being a show car but idk where to start. I do understand that this car is as heavy as the the G’s but basically share the same engine platform (VQ35HR) as the 350z and the G35 less
Hey everyone,
I have a 2010 Infiniti G37X AWD Coupe that just had a full VR30 7AT transmission swap done using the Z1 Motorsports G37X VR30 swap kit and JOL flexplate. The reason for the swap was that my original VQ37 transmission had an internal cooler failure that caused ATF to mix with coolant, contaminating the valve body and TCM. Rather than risk reusing contaminated parts I opted to run the VR30 valve body and TCM as is from the donor 2019 Q50.
The issue:
• Hard aggressive shifting in 1st and 2nd gear, smoother after that it seems okay but not shifting at 2500-3500 rpm
• Manual mode not functioning at all
• Car also had a dead/dying battery which was throwing CAN communication codes those were cleared and haven’t come back after driving it 5-6 times
What the shop told me:
The mechanical swap is solid. They’re pointing me toward tuners saying it’s likely a TCM/electronic issue not mechanical.
What tuners have told me so far:
• One tuner said the VR30 TCM can’t operate properly on a 2010 G37 and that full functionality including manual mode only works on 2013+ G37s recommending I source a clean VQ37 TCM
• Another tuner said they’ve done this swap many times and shifting should be normal currently waiting on their full diagnosis after sending them the codes
• Third tuner said they can tune the aggressive shifting but cannot fix manual mode through tuning alone
Attaching the scan results from the shop.
Has anyone run into this doing a VR30 swap on a 2010 G37X coupe? Is the VQ37 TCM the move? Can it then be tuned to work properly with the VR30 setup? Any help is appreciated.
On my 2WD M35, can anyone tell me the location of the crank position sensor and the color of the connector? I've already changed out the valve covers and cam sensors from a previous episode. Thx
2015 QX 60 still on the original engine and CVT.

Hey guys. I’m having a really weird issue with my Infiniti. I was driving on the highway maybe at like 3,000 rpm. There was traffic buildup so I had to hit the brakes kind of hard. As soon as I did this, the rpm jumped 4,000 and made a revving sound. It has done it a couple times over this weekend . Only when I’m braking light or hard. Any ideas what it could be?
I also have these codes
P0725, P1815, U1000
I own a 2019 Infiniti QX50. The engine started making a strange noise, so I took it to the dealership, where they told me the engine needed to be replaced. This is absolutely not an option for me, as the car is already out of warranty. Upon researching online, I discovered that all vehicles in this series—from model years 2019 through 2022—were released with a manufacturing defect, and the government has issued a safety recall. However, the dealership refused to honor the recall, they claimed that I had been negligent regarding oil changes and had ruined the engine myself—a claim that is absolutely absurd. Has anyone else here experienced this problem? At this point, I no longer know what to do.
Started hearing this the other day, but my car has been shaky for some time. I’ve been told different things like it could be a break rotor, but I’m leaning more towards a wheel bearing just wondering what part I should fix an ex I even thought it could be the rack and pinion, but I feel like I’d have so much more play in the steering wheel if it was.
Help! I just had my twin turbos replaced on my 2018 Q50 and the dealership is now saying they hear a secondary noise coming from the AC compressor… AC is fine, belt is fine for now, but it’s out of alignment. They want $600… is this crazy high and what do I do? I already negotiated down from $750. Thank you for your help!!
Hi everyone. My A/C yesterday in pretty high heat was not working, blowing warm air. I bought a recharge kit last night.
This morning, the gauge went straight to the red zone (high pressure). The car was blowing cooler air (tbf it was cooler out this morning). I took a look at the compressor and it wasn’t engaging. The belt was moving but not the disc wasn’t moving at all. I don’t hear any weird noses or anything.
Based off of some research I am thinking the pressure switch could be failing? I’m going on a road trip next week and really don’t want to fully replace the compressor in this car. Any thoughts, advice, or other checks I could do by myself? Thanks guys!
2014 q50 vq37. Stalling while revving or under heavy load. Dealing with some gremlins, have an issue where under heavy acceleration the car dies. Have had a few "smoking guns" had water from sunroof drains in the bcm, fixed that. Oil intrusion on passenger side cam position sensor, fixed that with new sensor. Found a few vacuum leaks with smoke machine, fixed that. has had a few repeat codes for maf replaced both maf and fixed wiring issues. Found transmission to have incorrect fluid and material, replaced it and performed relearn. Vehicle was in an accident and had a few things replaced body wise wiring looks havway alright but not great. Customer replaced both cam position sensors and crank position sensor and o2 sensors and cats, all seem to be reading as they should be. Now to the issue that im still having with it, while driving under heavy load wot it dies. Revving it under no load it revs to 3.5-4k and then dies same way. Under light revs to around 2.5k it hunts for a few seconds before slowly settling back down to idle. Performed idle air relearn, have checked continuity to throttle bodies and cam position sensors to ecm, have inspected ecm connector. Still having same rev and die issue. No codes other than when it dies for cam and crank position freeze frame shows nothing of use. Any help would be greatly appreciated.
Update: currently hunting down ground issues and possible alternator issues, during a data log, which ill try to attach, found ecm to see 17+ volts just before the stall. Will update as issue progresses.
Update: Update: Live data of ECU showed 9v at idle. When rev to 5k to where it would die. ECU showed 17v.
Battery voltage tested via meter read 14.4 the entire rpm range
Checked ground wires to ECU 123.124.127.128 smallest connector. All were okay
Checked power wire pin 125 in same connector. It was 9v when it’s supposed to be 14.4
Followed wire back to fuse 38 on the ipdm and it was blown.
The maf is also on that circuit so I suspect the poorly spliced together maf wiring may have shorted or touched any other wire.
She’s running good so far

So after aggressively driving on a highway, i came back to my driveway where i noticed a burning smell. I checked under and saw oil all over the control arms (i think thats what their called) and it looks like oil just exploded all over the bottom of my car. I also saw a little bit of what it looked like to be white smoke. Ive learned that these cars leak, burn, and consume a lot of oil. Im trying to figure out if its still safe to drive and to just top off the oil? Would love some help!
Officially part of the Infiniti fam 😎 Just picked up my 2018 Infiniti Q70 AWD and I’m loving the car already. Smooth ride, luxury feel, and still got some power when you step on it. Has its minor flaws at 100k but going from an Altima to this I have no complaints lol
Still learning the platform, so I joined the community to learn from people who’ve owned these longer than me. Any tips, common maintenance advice, recommended mods, hidden features, or things I should watch out for with the Q70? Appreciate any advice from fellow owners
Is this too good to be true? I've combed through the Carfax and it seems well taken care of. I understand the V8 is a thirsty engine. Google says to avoid the 2011 batch of vehicles but from my research it seems like people do good with this vehicle as long as it's maintained.
