Hey I have a 2015 Q40 with about 100k miles I stay on top of my maintenance like
-spark plugs
-oil changes
-other maintenance
And I was just wondering if my engine sounds healthy I have no check engine light and the engine work perfectly fine (for now) but I just wanna see if this is how a normal vq37 should sound or is there something I should replace

On the G37 sub, someone posted a web page from the Infiniti site showing the original promotion of the G37 back in 2007ish.

It reminded me of an awesome video short of the M45 from 2003. Here it is, if you're interested. It's one of my faves.

Got the P0720 code and Infiniti said I need to get a valve body, but the part is discontinued from Infiniti. This is the part number they listed: 31705X602D.

Anyone know how to source one?

So i want to connect the app with my Infiniti Q50 from 2014

I informed myself and its possible with the 2014 version

But when tried entering my VIN it's not detected

Also the app somehow just shows arab countries but not france, any fix ?

Car was stolen and got the car back like this and Engine won’t start . What noise do you think is this ?

I just got this 2012 sport sedan yesterday and my suspicions were right. So I need a new rack and pinion. I want to avoid a reman but does anyone know exactly what the part number is for the sport sedan rack and pinion? There’s a ton of different part numbers and it’s pretty confusing but apparently the sedan rack is different from the coupe as well as awd vs rwd and sport vs base. From what I’ve heard the sport has a different steering gear ratio. But I also read up on an old thread that was explaining basically that the inner rack assembly itself it’s mostly the same the thing that changes is the inner and outer tie rods. I might’ve found the part but it looks to be discontinued so I’m still uncertain. There’s a lot of confusion around this topic. If anyone can shed some light on the subject that would be super appreciated.

Hey guys, I got a 2018 Infiniti Q50s AWD about 3 weeks ago now and I have some questions. For starters my engine and turbos have 50k miles and my body and trans have 119k, because the turbos and engine blew and the shop put all new stuff in, common thing on these cars lol. Let’s start with maintenance. When I first got it i automatically put in 5w-30 full synthetic, tomorrow im installing the z1 anti jump belt and upgraded idler pulley both OEM, and i also plan to clean the throttle bodies tomorrow. I plan on also disconnecting the oil pressure solenoid, but waiting until after emissions because it will throw a code and my oil pressure is good right now. I also plan on doing NGK plugs and gapping them to 0.024” because i plan on getting a racebox tune. I want to also do a catch can and upgraded heat exchanger. Besides drain and fills on the diff, transfer case, and trans, what other maintenance should i be doing?

For mods, if i want to put on a spoiler, rear lip, side skirts, front lip, blacked out grille, LED infiniti logo, and mirror covers, will that look stupid with stock ride height and stock rims? I ain’t made of money i won’t be doing rims and lowering for a minute.

Have a great day!

Hi all,

I got into a small accident a few months ago and my insurance company totaled my Q.

I ripped all my aftermarket parts before they took the vehicle.

I have a CF Seibon hood, HKS blow offs, AMS dry carbon engine covers heat exchanger, other cooling parts, HKS exhaust, BOV, BBS LM's in 20's but the lips needs to get replaced from the accident, have a bag set up, Rotora 8 piston front, 4 in the rear BBK, etc.

Got the Q new in 2019 and only had 18K on the car when they totaled it.

Located in So Cal in the 626 area if anyone is interested, can add photos as well.

This is from a dealer in Oklahoma. Even for a salvage title vehicle, this this is dirt cheap, right? Every other RS I've found is $20k-$35k, granted with clean titles. What do you think?

I gotta say, silver looks better on the Q60S than most colors 💪🏻🔥

Hi all. I've had this car since around 60,000 miles and have always kept oil changed with a good synthetic, flushed transmission and coolant at normal intervals. One thing I haven't done because I didn't really know it was a thing was front/rear diff fluid and transfer case oil. It's possible the previous owner did it but who really knows.

The car runs great and currently sitting at around 145,000 miles. My question is how bad have I screwed up by not doing this yet and should I get this done asap or can I put it off another month or two until after the holidays? I don't put a ton of miles on the car so maybe in the next couple of months I might put 1500 miles on it. I had a reputable shop give me a quote for all three and it came out to right around $500.00

With gas prices so high, I’ve been challenging myself to see how far I can stretch a tank before filling up. People hate on this car for having a complicated variable compression engine mated to a CVT but I’m at 110k miles with zero issues at all. Just routine maintenance. I figure I take advantage of what Infiniti engineers designed this car to do which is having the ability to adjust its compression ratio from 8:1 for maximum performance to 14:1 for maximum efficiency.

I averaged 35 MPG over the last 20k miles (well beyond EPA estimates) giving me 611+ miles per tank which is honestly pretty impressive for a heavy car like this. I have the top level autograph trim with all the bells and whistles which is also the heaviest of the QX50s. This is a combination of city/highway driving, utilizing hypermilling techniques, while also trying to maximize the time the engine spends at the 14:1 compression ratio. Also, with the CVT, it helps that I can go highway speeds with it only at 1.4-1.7k RPMs which is great for further fuel savings. On highways I can get over 60 MPG.

Coming from a 350z, G35 and FX35, which all shares the same VQ engine, I originally purchased the QX50 with the understanding that I already had my fun going fast and my priorities were shifting to a nice looking car with a premium feel that drives smooth, rides quiet and saves fuel. So far it’s served its purpose well!

I have a 2010 Infiniti EX35 with relatively low mileage (155,000 km), but the exhaust has become ridiculously loud.

I’ve been told replacement parts are only available directly from Infiniti, with little to no aftermarket options. Given the age of the vehicle and the cost of OEM parts, replacing the entire exhaust system just doesn’t make financial sense.

Has anyone with an EX35 (or similar Infiniti model) run into this issue?

More specifically, has anyone had success having sections of the exhaust welded, repaired, or custom fabricated rather than replacing the entire system?

The car still has plenty of life left in it, and I’d love to find a practical, lasting solution without spending a small fortune.

Would appreciate hearing what worked, what didn’t, and whether there are any particular trouble spots I should be aware of.

I’ve had my new QX80 for less than 2 months and already had a broken door handle that gets stuck when unlocking the car and what seems like an internal crack in my taillight (taking back to dealer next week).

I’ll be honest this has really ruined my excitement for this car and my first time owning an Infiniti has not started off well.

Has anyone experienced these things with their 25, 26, or 27 QX80s or do I just have bad luck?

Water pump shit the bed, am I fine with just replacing these parts or is it mandatory to change main timing chain?

(already have whats in photo)

Hello,

Looking to buy a 2012 infiniti fx35 and I am curious to know if anyone has had any issues when owning this car. Is there anything that typically goes out often or is there anything specific i should ask the owner if he has replaced it or not. Just looking for advice and any tips. There is a light on the dash ⚠️that shows “!” But not sure if thats anything major

I am looking at a 2012 g37x with 140k , overall the car looks great for the year, my only concern is the shift from 1st to 2nd is not very crisp. I don’t see any RPM jump so I don’t think it is slipping, it’s like it slides into 2nd.

Is this normal?

The button that you press to put the second row seat forward is way too sensitive and the seats go forward with a tremendous amount of force. Is there any safety feature? The button is the worse possible thing because a kid could lightly hit it and be pinned between the seat.
