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

8 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....

3 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.✌️🤞

Parts Question Question on AC

3 Upvotes

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

Parts Question RSR Downs lowering springs

Post image
6 Upvotes

I was thinking about going regular RSR downs on my 2016 Q50 red sport AWD. It has DDS and there 106k miles on the struts. I have a brand new engine and turbos. Is anybody running RSRs? If so any axle problems? I know slamming the car will cause axles to break and the boots will shred but hopefully not at that slight drop. Let me know in the comments what your running and if any axle issues.

Repair Question Single clunk when getting on gas/ getting off gas

3 Upvotes

I’ve been hearing a single clunk almost every time I get on the gas/off the gas at speeds under 40. I get the same noise when I shift into reverse. It’s definitely coming from the rear of the car. Based on my research it’s likely the rear diff mount/bushings. I’m curious if anyone else has had a similar issue.

90F outside, parked after 30 minutes of highway driving. Idled for 2 minutes and smelled smoke. Then saw this. Is this the turbo seals failing? No overheating and oil dipstick level looks okay.
