1) The wheel bolt/nut system - A total shock to me when I swapping my winter tires. I thought I can still fit my Gen 1 into the Gen 2.

2) Gas gate cover - It was push open style in Gen 1 but a lever in the cabin in Gen 2. I have the hybrid and I don't need to fill up as often, so it will take me a lot longer to get used to this.

3) Interior door latch location - I am not so much about the push in the latch to open, but it is where it is located that took me a good month to get used to.

Anyone want to add more to the list? I think it is fun for people have just transition to the Gen 2 NX and remember the good old time.

 

I didn't drive a Gen 1, so can't compare. That being said...

 

I came from the 2IS and we had a latch release for the fuel door; so that wasn't much of an issue.

I found the door latch different at first, but it was very easy to get used to. In fact, it's so intuitive that I don't even think about it anymore. I occasionally find myself trying to use that when I'm driving the missus' Sienna. Every car should transition to this IMHO. And the safety system it ties into has helped me quite a few times.

The only thing I find annoying is the finicky wireless charger. It never works first time and I always have to fiddle around with it to get it to work. So annoying.

The infotainment is great, vastly superior to my 2IS and firmly brings Lexus into the modem age. Hopefully they'll take full advantage of pass capabilities and provide OTA updates to improve it. I'm not holding my breath on that one though.

 

So what exactly is the deal with this? I have been trying to determine if I'll be able to use my current RX alloy winter rims on my upcoming NX. My NX is supposed to come with the 20" wheels, my RX has 19" wheels. Width, tire diameter, bolt pattern, hub bore all seem to match, but the NX seems to use a different thread/nut size. What exactly does that mean outside of just needing to use NX fasteners? Is there something more special about the shape of how the nut mates with the rim as well?

 

Someone needs to correct me if I am wrong.

Gen 1 uses a nut style to secure the rim.

Gen 2 uses a bolt (mostly used by European Cars) to secure the rim.

The problem I was told when I swapping in my winters, the mechanic said because if this, my existing rims would not fit. It could be the garage is lying to me, but I don't see the reason why.

I think I have an explanation on why it would not work in one of the videos.

 

The thing with the old style nut fasteners is, it doesn't matter what the holes on your rim are like; the nut grabs onto the studs and holds your wheel in place.

With the bolt style, the rims have a recess and each hole which corresponds to the conical tapered base of each wheel bolt (technically, a part of the shank). So the bolt actually goes a bit recessed into the rim allowing for better grip and less vibration of the entire wheel assembly. The very design if this wheel assembly relies on that part of the shank being recessed within the room as opposed to sitting flush like it would on a wheel assembly that uses lug nuts

If your current non-2NX rims do not have that recess around the holes for the bolts, you won't be able to get the bolts to seat properly, causing vibrations, improperly balanced load and the wheels and a bunch of other hazards which you would rather not experience.

So, ultimately, check your rims. If they have the required recessed depth around the bolt holes, have the proper centre bore and the hole spacing matches, you should be able to use them on your new, shiny 2NX

 

Wow. Thanks. That explained it all. It was the style of the lug bolt, no so much the nuts vs bolts.

 

I had completely forgetten about @lsft 's video series.😁

 

Those lug bolts will be annoying for sure. And it’s odd they went from pushing the gas door to using the button inside. Manufactures now are switching to pushing the door. I wonder why they went back that route?

 

I think it has to do with the overall door locking mechanism. On my Gen4 non-hybrid RX, it was the push fuel door to open. The fuel door lock was interfaced with the door locks, if the car was locked you couldn't open the fuel door. In the NX Gen 2 case, the fuel door is separate from the lock system entirely. I like the separate button better, but that's likely personal preference.

The hybrid Gen 4 RX had the separate pushbutton to open the fuel door.

 

Definitely the new wheel lug bolts for me however you or a qualified mechanic can put your own studs on your wheels like ALL Lexus's had the previous 31 years. The ball radius lug bolts are a cost cutting and in the end a money making scheme for them. They also limit what type/style of wheel you have to use. Not many wheels take radius lug bolts including ALL previous Lexus wheels and 99% of aftermarket wheels.
You can still use your factory wheels ,just have to get ball seat lug nuts.

You or the tire shop monkeys strip a lug bolt hole and it's close to $1000 to replace the whole wheel hub assembly since the threads are in it.
Where if they broke or stripped a stud, like we previously had, and it's less then $20 as each one is easily replaceable.

I previously had a BMW M3 and it was the same ball radius lug bolts. I replaced with studs as a lot of BMW owners do. Read over on the BMW forum of some of the nightmares of lug bolts cross threaded/stripped by tire shops and impacts..

 

Yeah that’s true, forgot about the door locks being linked to the gas door. It’s fine for me, I’ve been pushing a lever to open the door all my life. Had an Acura for 1.5 years and I always mumble to myself “stupid gas door needs to be pushed open and I can’t lock my car while fuelling. Why do they have to copy Germans”

 

Thanks for this video, it was helpful. So in it was mentioned you were not able to find lug bolts with flat seats, just ***** and cones. However, there seems to be a few options for M12 to M14 bolt to nut conversion studs (for German cars, but it seems we have the exact same scenario coming to pass for NXG2). I haven't yet looked at my aftermarket rims to see exactly what kind of seat they have, but I guess the follow up question would be, does it seem reasonable if necessary to simply swap these conversion studs in and out (using my old existing lug nuts) along with the seasonal tire change? Assuming that I have a good hex tool to remove them...

 

#4) I miss the analog clock - I thought it is the signature piece for all the Lexus interior, and I can't believe the designer removed this iconic piece.
