Car Buying Advice 2013 3.7 vs. 2019 3.0t

1 Upvotes

To preface this, I'm in Central Europe, so the 3.0t is the 405HP Q50S, while the 3.7 is an American import (3.7 was never sold in Europe).

3.7 supposedly has 125k km (78k mi) on the clock and costs $14k.

3.0t has 85k km (52k mi) on the clock, costing 24k.

I know generally the 3.7 is regarded as more reliable (at least engine-wise), but the age difference and the fact it's an import makes me lean a bit toward the 3.0. Thoughts?

General Question So finally looking to change out my stock tires for my 2015 q50 3.7 awd (read below)

Also, I apologize any typos in advance since I am using Siri to help me type.I’ve been slowly building my q50 to give it that red sport look and now what I need is to get some new rims and tires I live in Washington state I wanna give the car a sporty look while retaining the factory OEM look as well and the reliability that it has carried me so far with the stock rent and tires currently, I have these Potenza run flats that I think it’s starting to tell me that I gotta get new tires and I’m thinking of course as well ditch in the rough flats specially now since I’ve been talking to ChatGPT that I use Michelin cross climate 2 for my other vehicle for my Mazda CX five and they’ve been really well for me so I’m curious has anyone use those type of tires on a q50 ? Both of them are AWD. So I’m just trying to figure out. I’m not really too much on performance tires they’re both my daily drivers and definitely a person that prefers the quality tires that gives confidence and comfort on the road. Though I’m trying to upgrade the rims as well. Should I consider buying used or new rims directly from Infiniti? Or there’s any rims that are similar that will fit and slap on without doing any mods cause my preference on rims also would be like this glossy silver black color instead of these stock silver rims would like to know more I seen post in the past, but I’d like to know since I’m officially looking into. That is only getting new tires but new sporty rims officially. I just wanna keep it OEM as possible as everything is OEM stock so far minus the cosmetic upgrades that I did. Forgot to mention my current wheel size are 17 inches and I’m planning to upgrade to a sporting look rims like a 19 inch and I want to know if that can also fit onto the specific car especially for being a 2015 and a 3.7 AWD.

Car Buying Advice Fair price?

Bought a 24 Q50 RS CPO from Infiniti 8mos ago for 45k with 14k mi. Now at 22k mi, no accidents. Bumper-bumper warranty until late 2029, and drivetrain until 2031. Overall in pretty good shape.

Is asking ~$40K too crazy here?

Also if anyone out there wants to trade for an NC or ND Miata hmu.

Repair Question Q50 Light issue NEED HELP!!!!!

1 Upvotes

Okay so to give some context, both high beams and low beams work as should, the DRL light on the driver side works when I lock, unlock, or start the remote start. BUT when I actually start the car meaning drive, the light turns off and does not work. As for the passenger side, The DRL light does work but is slightly dimmed. I am hoping to know what the issue is and how to fix it. I have checked the fuses and everything is good. I am now trying to access the headlight wiring in the easiest and most simple way to see maybe if there is a lose wire or grounded wire. I really hope you guys can help as its driving me insane

Modification Question Redsport oil cooler on a luxe?

1 Upvotes

Need some help from someone who might’ve done this already.

Z1 offers an upgrade but it’s 600 dollars and it leaks according to multiple people. So now I’m looking at fitting the oem oil cooler from a redsport onto my luxe. Problem is I don’t know what else I need. From what I understand, I need the oil cooler, the lines that come on it, and the oil filter housing from a redsport, which has a thermostat built into it. Is this all I need?

I have a 2021 Infiniti Q50 3.0T with about 53k miles.
For the past few weeks I’ve had an intermittent cooling issue. The car does not overheat during normal driving, but during a hard pull the temperature gauge will climb toward the middle (it never reaches the hot zone) and then drop back down to its normal position after I let off the throttle.
A few things I’ve noticed:
No check engine light.
No stored diagnostic codes.
Coolant reservoir has been below the MIN line at times, but when the dealer had the car they filled it to MAX and said it stayed there.
Dealer pressure-tested the cooling system and didn’t find any leaks.
Shop foreman drove the car about 50 miles and could not duplicate the concern.
The technician’s notes say:
No codes stored.
Could not duplicate failure.
Water control valve may be failing causing these concerns.
He told me the water control valve (electric thermostat) is the most likely culprit, but he also said he can’t pinpoint the diagnosis because he couldn’t reproduce the problem. They’re recommending replacing the water control valve as a process of elimination.

Modification Question When to tune?

1 Upvotes

So I just installed a catback exhaust. My original plan was to add an upgraded heat exchanger and then upgrade my downpipes a few months later. I know with the downpipes I will need a tune but if I add an exchanger will I need one immediately? Or would it be better to add both mods at the same time and then get the tune?

I just got a RS for 13.5 (80k rebuilt) and after inspection it’s in very good condition w no codes. But I see people posting that M340i’s are better and it’s making me a bit questionable about my purchase. Was it a worth it deal?

Repair Question 2015 P0720 SAD DAY

2 Upvotes

Today at 271,XXXkms , my car was stuck in 3rd gear and booted me out of manual mode. Luckily, I have a shop and scored a used VR for $400. A part of me wants to try replacing the speed sensor since I have the means to do so, but the labour hours make it inefficient to do. I'm excited because the Trans was sluggish, so it'll probably be a lot better.

In the future, if anyone is thinking of going the VR trans swap, call local car recycling places.

General Question Q50 Hybrid braking issues?

Enable HLS to view with audio, or disable this notification

9 Upvotes

Every time I come to a stop, right before the car fully stops, it feels like the brakes suddenly lock up or grab really hard. It jolts me forward like I’m brake checking myself.
Earlier, I was watching the RPMs while the car was in EV mode, and I noticed the RPMs would randomly go up even though it still showed EV mode. Shortly after that, the “Chassis Control System Error” warning popped up.
The car is a 2014 Infiniti Q50 Hybrid. Has anyone experienced this before or know what could be causing it?

Modification Question Im doing a whole suspension upgrade (2018 Q50 Luxe/3.0/daily driver). I've had all the parts for months, i just now have gotten the chance to start putting them in....

2 Upvotes

Im putting this under mod questions, in case anybody has suspension troubles they need to remedy or are thinking of upgrading. The parts i'm going to install are as follows..

•Stabilizer bar end links

• Inner/outer tie rods

•Megan Racing Fuca's

• BC Racing Coilovers/Non DDS/AWD

• SPC 6 piece rear adjustable arm set (camber/toe/trailing)arms

•Possibly upgraded CV joints, i haven't gotten them yet, but i'll most likely get a set of the M56/Q70 axles before i put the coils in (there is ALOT of mixed info about the necessity of upgraded CV joints with an AWD, with a minimum drop..1" or so, but i don't like to leave ANYTHING to chance). Some of these stock parts i suspect are completely worn, some of them i'm just replacing only because i'm upgrading, or just swapping them new for piece of mind.

After this, i'll probably put in an upgraded stabilizer bar, and then keep working my way around the suspension as needed.. rear lower control arms, etc. I'm at around 77kmiles.

Today i replaced the stabilizer bar end links w/new A-premiums. The new ones were stiff and barely had any play in them. The old ones were like limp noodles. Quick and easy (probably the easiest mod i'm about to do). Upon test driving the car, the wonky feeling i had when turning the wheel is gone and the car is stiffer and handles much better around corners. Next week is inner and outer tie rods. My plan is to drop the car off late aug, and have the coils, and possibly the fuca's (if i don't have time to get them in myself) installed by a shop, only because it's much easier to do the coilovers on a lift, and then have the car aligned. I'm desperately trying to get to rims and tires, but i feel like there is no point till next spring. I prefer to do performance mods, before completing aesthetic mods. I'm getting there, slowly but surely.✌️🤞

Only sometimes my driver side vents will blow hot air when the thermostat is set to 60 or whatever it stays hot, then it will fix itself randomly.

I’m sure it’s a simple fix just curious if anyone ever had the same problem to save me the research, thanks.

Repair Question Need new starter /advice on repairs

0 Upvotes

Just for a bit of background, I'm inheriting my parents' 2017 Q50 Redsport so the car is about 10 years old, and was daily driven by my mom for the most part. She always kept up with basic maintenance like oil changes and tire rotation but I'm 99% sure most of the parts inside the car are the same ones from 10 years ago when we bought it. (Which means now its my problem to start replacing the stuff thats gonna go bad)

I'm a bit new to alot of car stuff but Im 99% sure the starter is going bad. How do you guys usually handle repairs? Is it better to buy the part yourself and then have the mechanic deal with it (Im not getting under the car do not trust me with that) or is it better to drop it off and let them order the parts? Also when is it good to go third party vs straight from infiniti parts?

General advice on maintenance would be so appreciated I want to make this car last until the end of time. I'm a firm believer in keeping up with your older cars rather than buying a 2026 (im also emotionally attached to it as it is the only car I know)

also i think the odometer is either at 95k or 96k

2015 3.7 104k. Traction light also turned on. Disconnected throttle bodies, cleaned them, replaced the gaskets and torqued to spec. Also did the simple version of the idle relearn. Maybe the ECU just needs time to readjust?
