Has anyone who gotten their NX notice how their mirror itself is loose on the driver side? I was wondering if folks went in to check it out. My dealer said it was normal on another NX450H+. However, my old Lexus and all the other cars I driven, the mirrors were never that loose even at drive speeds at 30 mph. Wondering if I should just email Lexus directly.

 

I've seen a couple posts in the forum mentioning the same issue. It was also referenced that Rav4 models face a similar issue where a TSB was issued.

 

Yeah dealer said it was "normal". Thats why wondering if I should email Lexus corporate.

Also don't know why the titel is NX 4th gen instead of NX450

 

I believe that this has been covered in another thread and the solution has been to swap the bolts on the side mirror with bigger bolts. As another member mentioned, the RAV4 was plagued by the same issue and it had the same solution. It also appears that even the Gen 1 NX suffered this.

 

Toyota to Lexus- For the new NX, you are to use the TNGA-K platform the we used in 2019 for the Rav4.
Lexus to Toyota- Great, you guys got all the bugs worked too. And thanks, with your constant improvements, you always make us look better on JD Powers surveys.
Toyota to Lexus- Yes, it the Toyota way!
Lexus to Toyota- Hey, we are getting the same complaints about the driver side mirror shaking? Thought you guy fixed it!!!
Toyota to Lexus- We did, We fixed via a TSB using stronger, bigger bolts
Lexus to Toyota- Why did you not tell us too, when you told us to use TNGA-K?
Toyota to Lexus- Bolts not part of TNGA-K platform.

If this mirror shaking is still around, it is really odd after fixed 3 years ago on Rav4. LOL

 

The same issue seems to have affected both 1st and 2nd generation NX and 4th and 5th generation RAV4. When I talked with the service advisor at the Toyota dealer about the issue on my 2021 RAV4 hybrid, he showed me the TSB that Toyota issued. Yes, it did involve replacing the bolts used to mount the mirror.

I read the procedure for replacing the bolts. It involves removing the interior door panel and various components inside the door to get access to the bolts. Then, when the bolts have been removed, the holes for the bolts in the sheet metal need to be drilled and enlarged to accommodate the large bolts. After seeing what had to be done, I decided, for now, at least, not to have the repair done. With having to take apart and reassemble many components, I was concerned about the possibility of introducing new rattles. I was also concerned that, when the holes in the sheet metal were enlarged, there might be a possibility of corrosion developing around those holes down the road. The vibration from my mirror is actually quite mild. You really only notice it when you slam the door shut, and it only occurs periodically. So, I decided just to live with it the way it is.

Also, I'm not convinced that the problem is actually caused by the bolts. I think that there is the possibility that, with Toyota and Lexus trying to reduce the weight of their vehicles, they are just using thinner sheet metal for the doors and that the shaking/rattling is caused by the flexing of that thinner sheet metal. If fixing the problem is as simple as using larger bolts, I would have thought that Toyota/Lexus would, after several years, have been using the larger bolts when the cars were being built, but the problem still exists in 2021 and 2022 NX and RAV4 vehicles.

 

Lesz, I believe you put your finger on it. If it were just the need for larger bolts (Toyota/Lexus are not stupid) they would have corrected this way before now. I believe you are right about the thinner sheet metal probably being the culprit and since very few buyers complain and push for a correction they may just not bother to do it right the first time. But then again, do replacing the bolts actually totally solve the problem? Just a thought.

 

From reading numerous posts on both Lexus and Toyota forums, there doesn't seem to be a consensus about whether the "fix" works. Some say it has, but others disagree. There also is not consensus about whether there is even a problem with "shaking" mirrors.

 

And it might just be a safety mirror brake away design to reduce injury if you hit t something or someone. And the reduce damage could be advantageous for both the object and door panel. If you complain, apply the TSB.

Like someone say, they are not so stupid to not fix something so simple for so longunless there is a reason. And if they are, I don't want the NX anyway that I can't seem to get anyway. Problem solved, I think.... LOL

 

@lesz - I agree with your thoughts. My 2016 NX mirror shook a little bit at higher speeds, but it wasn’t enough of an issue that I really gave it much thought. It still worked fine, and I am never a fan of digging into the interiors if there is a risk of introducing new rattles - if it can be reasonably avoided. It is disappointing that this issue still exists for a vehicle like this though. There is a reason Lexus dropped the tagline “passionate pursuit of perfection” as they don’t seem to take their own service bulletins into account when designing new models.

 

The crazy thing is when they gave me a RX to drive, it didn't have this issue at all. Mine occurs at 30MPH or below lol. This is the first time I ever experienced this through any car and the most expensive car too. So, thats why wondering if I should just email corporate at this point. They said previously that the Toyota SB only applies to Toyota.

This is the only thing that bothering me and the stupid rattle that comes and goes that is annoying because it makes it for such a quiet cabin. If those two were addressed the perfect suv for what it is.

 

I don’t know if there was ever a TSB on the 1st Gen NX mirror issue, but there was certainly a lot of discussion on this forum. The RX we replaced it with does not have this problem.

 

I've noticed this on my 450h+ as well. Haven't studied it in-depth, but it happens while on the highway. I was thinking the rearview mirror and passenger side mirror do it too a bit at different times. Never enough to bother me. I'm thankful for this group to validate that I'm not the crazy one. I am wondering though if it's actually me who is vibrating since it's all three mirrors ;-)

 

Probably should let your dealer / lexus know so they can come up with a long term fix.
