Bad Rear Differential
After having my NX for a month now, noticed last week a rubbing sound. It has gotten worse, took it in to be checked out and guess what ...rear differential has to be replaced. Not to happy right now......I have had 8 Toyotas without anything done to them other than regular maintenance. I move up to Lexus and this. Lexus service told me this was rare to have something like this. I want to believe them, but it is like when you have an accident with your car, you never quite feel the same about it, and worry if it will be right. I hope my opinion about the NX will not change, I really love this vehicle, but today has been a damper. The rest of you have a great weekend....mine is pretty much shot.

I wouldn't worry about it. Remove and replace component type work. It's not like they will modify or try to retrofit something. The AWD system came from Toyota's parts bin, so it's well known, documented and gone through its paces. Components fail, within reason. Let them do the work, and then decide if you even notice it was done.

Maybe these are so in demand that quality control is slipping ?

It's too bad you got a rare mechanical issue but like the guys have said above, don't sweat it since it's an external part that will be replaced with a new one.

No automobile is perfect. IMO it's much more about how issues are dealt with and Lexus is second to none in my experience. As a matter of fact I only have this NX because I went in to arrange the replacement of a dashboard on a 2006 RX. While there I saw the NX and the rest is history.
I was so impressed they were about to replace that dashboard on an 8 year old car that I bought preowned it never even occurred to me to go anywhere else.

I agree that this is likely a rare occurrence...and to think just because this is a Lexus that NOTHING should go wrong is an unrealistic expectation that will most certainly lead to disappointment. Remember the Consumer Report reliability rankings had Lexus at the top...but even this ranking did not indicate that there were zero issues with Lexus.

Lexus is the best, yet over the years on initial quality surveys for example, it still has had between 68-90 problems per hundred vehicles where the industry average is around 130-150. Perfection is relentlessly in pursuit, but not achieved and realistically never will.

Notified two days ago - coupling failure, need new rear differential system at the cost of 2400.
Only 73K miles, ALL maintenance done at Lexus.
Very disappointing, will not purchase another Lexus which is unfortunate. Have purchase eight Lexus’ at the dealership.
Probably a pandemic issue at root. Too bad

Just got on this website for the first time. A bit daunting to nav at first glance…

I'm sure if you had gone to a local mechanic for the work it wouldn't have costed $2,400 - perhaps half of that.
I'm also curious about the answers to Lexuswiz's questions (previous post).
