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.

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)

Knocking on wood as I type this, but nearly 200k miles on my 2015 Sport Hybrid RWD, and so far the only things I have had repaired were the transmission replaced for a cracked bell housing at 63k miles(they replaced with a different part number, transmission from 2016+ maybe? 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. Both were done under warranty(I had the 8 year unlimited mile bumper to bumper up until a month ago). Do get the slow driver window occasionally, but just hit it with lubricant once or twice a year.

Need help with issues on my 16 Q50 premium 3.0T awd. Installed aem intakes and jb4 tuner, then car went into limp mode after 3 days. Threw throttle position sensor code. Not sure if related. 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. There are no Infiniti dealers anymore in my area. Also, owners manual says transmission is maintenance free. Is that true? U never have to service it?

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!!

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.

I'm curious about this transmission failure. Never heard about it before. My sister had Ex35 for 8 years, did 180k miles, no problem with AT. I know that we have AT7, but is it that much worse? How about transmission from 3,0TT, IT is also 7AT, but I heard, that it can handle much more torque. Does it mean, that it doesn't have the same issue as 3.7 ? Are gears the same lenght in 3.0 and 3.7 :-) ? And finally - those doors blends, or how you called them. This a common issues in some french cars. I found, that, while, you change direction of flow, when fan is spinning fast it is more common to have this failure - maybe the same concerns Q50. For now I have 55k miles, and no problems with transmission or air door blend :) Greets from Poland.

It’s a very common problem in the 2014-2015 q50. Thank you for the comment and for watching!!

[@antsy602]

Nissan has the worst transmission, almost hands down.

[@SpeedCultureStudios]

@@antsy602 well now that’s not true lol. And it’s a pretty broad statement. The 7spd auto isn’t too bad overall and is actually pretty good in the newer Q. The cvt they use in other vehicles is garbage but that’s just because it’s a cvt. There are a lot of cars out there with poor transmissions with far more issues, I am sure.

[@antsy602]

@@SpeedCultureStudios My bad... Yes, the CVT transmission is exactly what I'm referring to. Trash...

[@TheGiantsfan428]

I was trying to figure out why my A/C was doing that, glad you listed that actuator in this video I can finally fix the problem.

[@Foxcraze]

Rear abs sensors I see pretty common also. I’m nearing 70k and so far so good with the trans, keeping my fingers crossed haha

[@SpeedCultureStudios]

I’m with ya!

[@adrianbrothers6925]

my car acted up on a downshift and the check engine came on one day. it went into limp mode and stopped shifting past 3rd gear. the valve body went bad on my 2014 3.7 at 90,200 miles

[@jackboyjoseph5135]

@@adrianbrothers6925 mines went bad at 115k miles I’m using my income tax to get it fixed since I have the title to the car I don’t wanna sell it

[@andygregg4056]

2014 q hybrid. Yup, had several these. My passenger occupant sensor also failed. The mat sensor, not the controller. It’s a simple strain gauge, no moving parts. But it failed. See q50 forum for repair details.

[@yeet_7563]

So...Just don't buy one of these period right!😂👍

[@SpeedCultureStudios]

No-just look for a few things before buying

[@gonzalez3605]

I have 2008 g35xs vqhr fbo and I never have any problem is very solid only ting I do is the maintenance

[@nameless5r]

120k miles and no issues.

[@BenitoLouis-e7o]

Anyone ever have a issue where you ac dose not want to blow through the dash

[@SpeedCultureStudios]

That is the blend door actuator problem I mentioned in the video. Easy x replacement

[@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

[@Loudredsport]

Love how the most replayed is the part about serpentine belt. For good reason too lmao, he is NOT lying about that shit either, it will shred, just a matter of time. Get a Gate®️ replacement belt, pretty sure they’re cheaper. Back in December 2023 mine shredded while I was driving on the highway, not fun.

[@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.

[@mikeg3529]

*getting ready to sell my fiesta st and upgrade to a q50* "Ah, its gonna be nice to not have to constantly replace that stupid blend door actuator that always goes bad" 1:28 😐

[@connorwalter1025]

Is the there fix for the super loud squealing when rolling down wet windows?

[@yeww2631]

All of what you stated has happened. Got a turbo replaced, windows squeal, and is slow rolling up. Struts on hood , gone to shit…. Low key I fuckin hate this car. But love it

[@SpeedCultureStudios]

Lol I know the feeling!

[@Turbo.s4]

Hello sir! how do you feel about the rear mounted turbo kit made for the q50 3.7? Worth it?

[@SpeedCultureStudios]

It’s awesome!

[@tannerkim_]

Where do you get that?

[@brandomvilla6533]

The ABS light came on and I got a message on the dash that says "Chassis Control System Error"

[@jameswilliams663]

my 2014 qx50 journey awd was made in Japan, 3.7l , 7spd. they have not been made in Japan in a long while, Mexico is my understanding now, im hoping this fact makes a difference in longevity and reliablity.

[@warrenvivier3136]

windows...blend door actuator...belts suspension rear diff bushing etc. LMAO I use to own a g35 before getting my q50 and now i got to replace the same shit all over again.

[@SpeedCultureStudios]

😂 some things never change

[@mugz90]

I hear realized the American q50 is missing a lot of stuff the japan version has😂😂😂. That's crazy you guys don't have automatic windows and many other things

[@SpeedCultureStudios]

What? We have automatic windows in the US q50 😂 but I would be curious to know what other options the Japanese version has. Maybe real leather? LSD? Manual trans?

[@trubroo7568]

My valve body went and everyone kept saying it was my transmission… nope! Valve body

[@bitrage.]

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

[@sclaalvarez88]

I just got a 2019 red sport with 17k miles but after watching this video I feel like going back to my accord

Everybody is missing the main problems besides warped rotors.... PLASTIC PIECE BETWEEN REAR HOSE AND CRACKING RADIATOR PLASTIC

Warped rotors only happened in the sport model and really not that often. The plastic cracking issue just seems to be popping up now on occasion. Still not as prominent as the others but that could change
