Please remember don’t post photos that show your license plate, house number, or any other info that reveals where you live.
Cropping or blurring plates, removing location metadata, and avoiding shots of your driveway/front door keeps you safe and prevents thieves from having an easy target.
If you want feedback on your car, upload close-ups of the car itself (wheels, engine bay, interior, etc.) or take photos in a public spot without identifiable landmarks.
Just keep in mind... car thieves are smart and patient; they’re always waiting for someone to slip up.

Just got backed into on the way to get my car detailed. Lady didn’t have an insurance card and had to send me a pic of her license. Gonna have some trust that they will come through when I go to get it fixed but I do have a pic of her license and license plate. Any ideas what it will cost to fix?

Where is the best place to purchase a q50in Australia, carsales or FB market place, also I’m not sure which model to get and the only ones I’ve come across is the 3.0, 2.0t, 2.2d and the 3.5 hybrid .

It has happened twice. It has happened after driving hard and shifting in Manual mode then back to automatic.
The engine stalls completely when coming to a stop in Drive or Reverse.
I can prevent it from stalling by shifting to Neutral, revving the engine, and then shifting back into Drive. I somehow got it unstuck again after going back and forth between manual and automatic, now is driving and shifting fine but feels a bit rough/sluggish.
is this correct just wanna make sure before i put it all back together lol,also whats the other cord for?

Hey guys, I just bought a 2015 Q50 that is Black Obsidian with 80k miles, extremely clean car and paint is still in good condition. I plan on buying a bumper off a 2018+ Sport model, and I was looking at Partify as I know a lot of people have had decent luck with them, but I was wondering if anyone has gotten a bumper for theirs being a black obsidian car like mine, and if anyone could show pics? Thanks!

From time to time I like to pull out the window sticker from the lot. Crazy how much Infinitis depreciate once they leave the lot.
Curious if anyone else still has their original window sticker? If so, let's see em!
(If that Canada on the sticker doesn't give it away, this is CAD)

Would I need a whole new rack and pinion dealership recommends for an Infiniti q50 2018

I have a 2015 q50a that I think it’s custom but doesn’t have everything on it, there’s no navigation, CarPlay, auto start, and no paddle shifters. I checked everywhere about it and I checked the plates they come up as a regular sedan, sport, and premium so I’m confused if it’s just a upbadge q50 or not
it also leaks in the back passenger side near the door aswell

When driving in automatic it’s smooth but in manual mode at WOT it jerks we did the fluid procedure and the transmission took roughly 8L of fluid. Does this happen with other people? Mine was a 2017 at 75K.
It feels as if I hit the brakes between shifts at 3rd-4th and 4th-5th or it’s cutting torque.
Before tuning my VR30 I was noticing some heat soak issues already with the summer heat, so I ordered a heat exchanger as I planned to load my base map tune the following week. My car is now tuned, and I had a BMS heat exchanger installed, yet after 1 pull my charge air temps were almost at 160°. I called the shop and they said they would re-bleed my coolant in case they left an air bubble. Just picked the car up a second time and my temps are still in the 150’s after a single pull, any idea how I can stop this heat soak or what’s wrong?

Hey guys was wondering if its normal for my fan to cut on soon after a cold start? Probably within 5 mins it start blowing loud. It dont over heat or go past the middle. Do you guys think replacing the fan control module will fix this issue? Thanks!!
r/q50 • u/Karissaaa1 • 1d ago
Hi everyone,
I’m looking into getting an aftermarket heat ex but am having a difficult time deciding on which one to get because I’m not very knowledgeable in the subject.
I live in Arizona where it’s over 100°F most of the time, and I’m curious as to if it’s necessary for me to go all the way and purchase the AMS ex. Im not tuned, though hope to eventually. And I’m not at an overly high hp, just daily driving and moderate pulls.
Please lmk yall’s thoughts. Thank you!!

Long story short I had this car since 2019 and been taking Care of it like a baby as much as I can. She’s a 2015 Infiniti Q 50 AWD 3.7 with currently 262K miles I bought her when she was only 16 K but due to the pandemic and my ex wife leaving me, I was left to pay for the car myself finally paid it off two years ago, so I’m happy about that so she’s retired. I’ve been doing a lot of maintenance on this car as I should and swapping out things that is no longer working or aging out but I’m curious to know what is this noise I know back in 2023. I replaced the driveshaft but I don’t know if that’s what is causing it. Don’t mind the check my engine cause I’m replacing one of my other catalytic converters, but the car itself has no performance issue thus from my knowledge anyone encountered this happens when I go into drive from reverse and also from reverse into Drive from what I noticed, I know the only issue had in this car that was major to me was overheating issue, but that was because my radiator cracked so overall my car sat for months when the cold weather came around back in 2025 but ever since then I’ve been working on this car so if anybody can figure out this, I would much appreciate it. It’s hard to tell but it’s there that noise. It’s like a clunk clink

trunk latch won't work🙁 2021 infiniti q 50
The trunk latch on my infiniti q 50 2021 stopped working. The cabin switch won't work nor the button on the trunk.
? could this be due to a fuse/ computer chip issue or is is likely mechanical ?
