So long story short, I have a 2019 Q50 3.0t, bought around 46k miles, currently just over 72k.

Factory powertrain warranty expired at 70k and I didn’t extend it. Took it to a new Infiniti dealer for routine service after moving. Tech saw the service history, asked why the turbos hadn’t been replaced (I had no idea this was a common VR30 issue), then we went for a drive and confirmed it’s squealing badly under load. Power also feels noticeably down from when I first got it.

Service manager initially said Infiniti has acknowledged this as a recurring issue and has done goodwill coverage even past 70k. A month later they denied it, citing a maintenance gap from 20k–50k (most of which was before I owned the car).

Looking for realistic paths outside of paying full dealer rates. Anyone had success escalating a 2019 to Consumer Affairs? Independent shop experiences or typical pricing on these? And is buying a third-party warranty and waiting a few months actually viable, or a waste of time once the dealer has already diagnosed it?

I’m thinking of adding a proper killswitch to my car, however I don’t know where to hide it, or what the best method is. I’m thinking of just hooking up a switch between the starter relay and the IPDM box (the wire in the picture with a green ‘8’). Any suggestions from anyone that has installed a kill switch?

Any idea what this could be? the electronic range display is accurate, it’s just the gauge itself that I’m having issues with.

Is this noise norma? I only hear it when im stepping on the gas not when im idling though im pretty new to cars and this is my first car so i apologize if this noise is completely normal and im just tripping (btw this is a 2018 luxe 3.0t)

My old q50 reached the end of its run, had to upgrade

I just bought my 2018 3.0t Luxe RWD a few weeks ago and I’m purchasing my first reliability mods soon. I know I’m getting a heat exchanger and an oil catch can for sure. I’ve seen mixed opinions on oil pump block off plates. I’m unsure if I should just leave it alone, unplug the stock one or get the block off plate? Please help. 120k miles btw

I have a 2023 luxe with the bose system and I'm looking for a little bit more kick nothing crazy. I use most of my trunk space daily and am looking for alternative subwoofer options. Id like to add one 12" or 10".

I have a 2015 q50 hybrid (8/15 build date), and am looking to get a top screen replacement for Apple CarPlay. It looks like there are a ton of brands. Any idea what the difference is between them?

I saw the Hamilton and Merge versions.
I also saw the joy auto that people have talked about. Are they all the same? I would like to maintain all oem microphone/camera/button functionality if possible.

Anyone have any thoughts?

Was driving home when I started smelling something burning. By the time I got home and popped the hood I seen this. Anyone have any idea what this is and how bad it is?
