For those who have issues with slow windows, DO NOT GO TO THE DEALER. Buy a lubricant silicone spray and spray along your window frame , give it 5 min and then put your window up and down a few times and bam brand new fast as hell.

Driver window started happening when cold for 1st use in day of window; only time it happens. No other issues. Had G35 for 10 years and only 10-yr battery went out but that's standard...and life. Other than driver window issue with Q50, no issues in 4 years.

[@tomz-5129]

Depending on how bad it is when we have that issue come in most of the time we just clean the track and then spray it with DRY spray lubricant if you don’t use dry spray it will work for a little bit then actually get worse more and more debris will build up (Infiniti technician)

For the belt failure you need to loosen the the a/c compressor and push it back and tighten it that’s why the belts would fail when you do that if you catch it early enough you won’t have to change the belt but if you still hear chirping then replace the belt (I’m an Infiniti tech and I own a 17 Q50s)

[@MorbidFM]

I personally purchased a universal 10 row single pass fluid cooler from Mishimoto and used -6AN hoses to cool the ATF in my 16' 3.0t Red Sport 400 awd, currently odometer is showing 93,346 miles and it was one of the best mods I've ever done. The cooler does the job perfectly, by matching up the hoses to the oem hoses i don't see much pressure loss or increase of pressure in the valvebody, it's not cooling the ATF too much or not enough. I can beat on here and drive it hard, or be sitting in traffic in the summer and it's working perfectly. I monitor my ATF temps just to be sure. My next upgrade will more than likely be another Mishimoto universal fluid cooler to replace the OEM oil cooler, but I'm monitering oil temps, just to be sure, since the red sport models have a thermostatically controlled oil cooler, guess we'll see in the next month or so.

It’ll be a fun project. starting with coolant flush. Pretty fun. Been taking it easy, shifts smooth. Still daily my 400 hp taurus it just feels like a cross over to drive and sits higher and it’s a little more convenient. i don’t like how heavy the pedal is in the q50. My g35 was reliable and I had a g37 for a short time and was missing that VQ. Very happy with the q50’s sound system and interior capabilities. Sounds good on cold start ! Probably going to just replace the rear dif bushing when i go in for rotors here soon. Having a slight strut-pop kinda noise from the rear when I launch, but 5 seconds to 60 and gets great fuel mileage around 75 compared to my taurus.

[@spideym35i]

Hey I’m from NC and am an Infiniti tech. Yeah turbo failure and also engine failure is very common on the OLDER VR30, think they fixed it 2018 and afterwards. Mostly an oil starvation issue similar to what the RB motors had from what I’ve heard, very rare issue is having a porous engine block that allows coolant to leak. The blend door motor is a bitch to get too, just a tight space. The slow window issue is most likely a window run needing replacement, easy to do. And as you said lots of valve body’s but I don’t see it as often. Great video as always!!

[@SpeedCultureStudios]

Thanks for the input!!

[@spideym35i]

@@maxziplock possibly yes a smell. Best way to tell is by pressure testing it and lifting the vehicle up. If you see coolant seeping through the block then it’s porous. I’d start by checking all hose connections first tho and seeing if I can find a trail of dried coolant

Thanks for posting on here.. i have a 2018 q50 redsport and i have an oil smell in the car when driving.

Oh im a long time g35, g37 and q50 owner. Its still under warranty and i am in alabama so my closest dealer is 4 hours away... any thoughts on things to keep an eye on? I think its injector or turbo related..

one I've experienced on the VQ37 and I've seen others having this issue as well is the plastic coupler for the heater hose. It gets brittle and can leak or full on fail causing coolant to leak every where. I replaced mine with a metal one to avoid this "ticking time bomb".

Happened in March 2019), and I had a rear sway bar replacement when I ran over some debris on the highway and it somehow snapped one end of the sway bar loose without breaking anything else.

I removed it and no issues since. Then replaced aem intakes with stillen and did a muffler delete with straight pipes, months after, car randomly died on highway. Very scary. Then tried installing Z1 motorsports hotbox piggyback tuner and it threw throttle position sensor codes and engine started up hard and running rough. Turned it off then engine wouldn't fire back up. Removed it, then it fired back up. Z1 asked if its been tuned. I have no idea. Doesn't seem tuned. Also, when I accelerate from a stop and then let off the throttle, the car jerks and gives me whiplash, I can't tell if valve body, back pressure, or something else. I have to let off the throttle very slow or it jerks. It almost acts like it gets stuck in gear. Please help. I've taken it to a Nissan dealer and they couldn't find anything.

Sup bro you think I can get rotors at auto zone for my 2014 q50 s…..I was thinking about getting the duralast gold or premium

[@SpeedCultureStudios]

You can. There are only a few actual rotor manufacturers, so a lot of the different brands you see out there are likely made in the same place. I don’t know anything about the ones you mentioned, but they are probably just as good as many of them out there. I’ve had good luck with R1 concepts

[@MyDomking]

That’s why I traded my 2014 q50 for a 2016 Lexus IS 200t f sport I was having transmission problems already with the q50 with only 38000 miles my lexus it’s slower but more reliable and more fan to drive

[@lornestein7248]

I bought a 2014 with 1 year warranty left. For that 1st year it was a good daily while warrantied. Within a week or 2 past warranty, that car fell apart on me like it was on a stop-watch. Will never touch Infinity crap again. Acura reliability for the win, every time.

[@Collectorofsats]

1. Definitely true I have a Q50S and just ordered some drilled and slotted rotors because of the vibration from the factory rotors.

[@biniamsamson1602]

Yea bro same problem here

[@user-mc2kk8yf5z]

what was costs??

[@So1i7ud3]

Rotors came first for me at 80,000 and I’m worried about the rear differential…damn but the rest is chillin cause I’ve actually modified quite a bit, my struts are not stock and I did this because the car is heavy AF let’s be honest the whole deal with the stock struts is probably because it’s a heavy yacht of a sedan with cheap struts. Also my injectors are not stock did that cause figured they didn’t ratio properly or use the right injectors for a big engine like a 3.7 as most other car companies have as well failed to improve on, and I upgraded my oil pan, got an oil cooler, heat exchange, carbon fiber hood to lessen the weight of the car a bit, upgraded sway bar, and lastly with the rotors I did not use the stock rotors I upgraded those and the break caliper as well.

[@SpeedCultureStudios]

Sounds like you have a nice platform you're working with. It's a solid car over all. Just like any car, they are bound to have their quirks.

[@briangousby8474]

Rear wheel speed sensors. Also any updates on diff bushing???

[@SpeedCultureStudios]

No updates yet on the bushing that I have heard-other than “soon.”

[@olabodealamu5297]

So same with my q40- I have changed my valve body, my diff is leaking as well. My rotors warped at around 50k miles. My door actuator failed as well 🤣. I have changed all these so I’m not worried anymore

[@SpeedCultureStudios]

Got them all out of the way lol

Great video 👍 I'm living in New Zealand and I got a q50s Hybrid AWD. In her very hard to find spare parts and now I'm looking buy the front shock absorber. Would you be able to give an online store? Thanks

[@SpeedCultureStudios]

Thank you for watching! I'm not sure of sites that ship international, but you could try infinitipartsdeal.com or check out moog's website.

I have a 2014 hybrid and I was told that the hybrid battery is going out and that cost over $10,000 I'm looking to buy a rebuild one so far the car is running good still with no problems it causes the check engine lights to come on time to time other than that the car has been faithful to me but I'm decided if I want to fix it or sell it 🫢🫣🤞🤞🤞

[@zzzr4604]

U nailed it with this video! Blend door actuator was about to be replaced on our 17 q50 Signature with 49k miles the other day. Dealer quote was around $518. Please post a video on how to replace that, I would greatly appreciate it. Already replaced belt once & rotors resurfaced too. Dealer couldn’t confirm my suspension concern so, I’ll keep an eye out on that next 😧 Keep up the great work! Thank you 💯 😃

[@Foxcraze]

The video he referenced on my channel will get you all set till he commits to doing the replacement himself. The link is in his descriptions and It’s super easy!

[@Muzacman02]

I bought my 15' Q50 with 70K at 81K my Valve body failed, When I opened the tranny up the fluid Looked like TAR, Infiniti says tranny is maint free for 100K BS!!! CHANGE YOUR FLUID REGULARLY , I swapped the entire trans from a salvage Car 30K. Good Video!!!! Keep em coming!

[@lilfatherlouis]

My car 2015 q50 AWD has 42k. And it’s showing symptoms of failing what should I do? Would changing the fluid help or do I need a whole new valve body. I’ve seen people swap it out for a 3.0 trans

[@user-qs4jh8hi7r]

I put a set of Drilled Rotors on my QX50 man made a big difference

[@SpeedCultureStudios]

It’s a good upgrade!

[@AbdullahAhmed-em5ec]

I have a 2018 3.0t q50 awd. There is trans slippage. Should I just change the valve body or get a new trans

[@SpeedCultureStudios]

If it’s slipping, changing the valve body may not improve the issue

[@nicoperez9984]

anyonw got any idea what could be wrong with my 2015 q50 3.7 awd? when i hit the gas it feels like jerky n like somethings holding me back and then is really bouncy n rough

[@SpeedCultureStudios]

Could be a ton of things. Trans, misfires from bad plugs or coils, MAF sensors bad or dirty. O2 sensors bad. Just a few things to look into right away

[@jjorr1]

My 3.7 makes a clink noise once every time I park. I reverse; I put it in drive, do you know about transmission motor mount

[@SpeedCultureStudios]

What do you mean do I know about them? It’s possible you’re getting the news due to a motor mount being bad or your trans mount.

[@mm-xy9qe]

My wife’s 2014 3.7 Q 50 had a lot of those problems but one I didn’t hear you mention or haven’t seen in the comments that I believe is fairly common is the infotainment center going out and there really isn’t much of a fix aftermarket wise. And it seems like every one of these problems is $2500 … damn

[@SpeedCultureStudios]

I haven't heard of the infotainment issue--at least not on a large scale. I know the 2014 system was a little laggy, but I haven't heard many talk about the thing just going out completely.

[@bitrage.]

Very true..... just don't go to the dealership for parts...... please, it's getting up there with Merc parts.... 🤯🤦‍♂️

[@TheMightyLambisCrew]

Just purchased a 2018 q50….DCU (infotainment) sound keeps going in and out. Is this common or a user error issue?

[@SpeedCultureStudios]

I’m not familiar with the issue

[@akem0020001]

some infiniti suv's also have a problem with that same diff bushing

[@SpeedCultureStudios]

I’m sure it’s the same subframe used, unfortunately

[@alexshell3389]

Where did you get that camera that showed underneath the car? Also what is it called ?

[@SpeedCultureStudios]

It’s a GoPro mounted to the underside

[@jovani6044]

Is this for all model year q50s? Are the 2020 and above more reliable?

[@SpeedCultureStudios]

Fewer transmission issues

[@dominiccgutierrez7531]

Valve body might be going out 2015 Infiniti Q50 rwd stock everything, should I replace that and keep the 3.7 stock tranny or just put a 3.0 tranny. And what prices for both?

[@SpeedCultureStudios]

Look for a 3.0t trans

[@chickenjo23]

I have those same wheels on my Jaguar XJL Supercharged. Looks great on the Infinity.

[@SpeedCultureStudios]

Great choice!

[@rulasg35]

I just changed my rear diferential fluid and noticed a stained diferential and the bushing is cracked, dried out. At this point I'm just leaving it alone. Car drives just fine

[@DG-888]

I worry about the transmission/valve body going out all the time. I dnt want to pay that kind of repair. If it does would you get an upgraded one or oem? I seen a video about a bullet proof valve body by some company.

[@SpeedCultureStudios]

I would just upgrade to the 3.0t transmission

[@treshaunmoore1133]

How much is a valve body on a Q50

[@rodneybryant1326]

Pretty sure the diff bushings can be had directly from whiteline or there is no difference between it and the G35/G37/Q50 diff bushing

[@SpeedCultureStudios]

Z1 says they are not compatible with the Q50. Outer metal sleeve is different.

[@easytee]

2017 Q50T Literally started hearing the "chirping" sound especially when it's warm or after getting the car washed with undercarriage spray! Everything else mentioned, slow windows, heavy trunk.. hell I think you were talking about my car overall! 🤣 BTW I had to replace my blend door Actuator!

[@SpeedCultureStudios]

lol such common things!

[@ng6950]

Just got my car back from the dealership for the valve body going out at 69,900 miles literally pulling out the neighborhood. Now I notice my diff is leaking :/ ! Thankfully valve body was covered under warranty does anyone know if the diff is too?

Hey quick question , have you heard any problems regarding speed sensor code p1721 , just bought a 2016 q50 premium and just saw this code pop up
