I'm at 22k miles on my Japanese built '13 RX now. Still not one single squeak or rattle.

2014 Canadian built that has recently developed a rattle in the driver's door that we hear when the door is closed, that solid door closing sound is gone. We are going to the dealer next week to see what they have to say.

At almost three years and 4700 miles, our Canadian built RX 350 has an occasional ticking in the driver's side B pillar. It isn't there all the time fortunately, but a bit annoying when it is. Our current Japan built ES has a minor buzz under certain road conditions after about 6 months and 5200 miles. Our previous 2004 RX was built in Japan and had a few minor rattles. I can't recall when they began but at 9 years and 27,000 miles, they weren't overly objectionable.

I would argue that most cars will develop rattles or noises sooner or later. I'm not personally convinced there is much difference between Canadian or Japanese built models. I hate the rattles but have just given up on the notion that a modern car is going to be completely rattle free. The last cars that we really chased rattles ended up being even worse after they attempted repairs. Unless it is overly offensive, I am now a bit gun shy about chasing down the rattles.

90k miles on our 2010 rx350 Japan built. Only rattle is glovebox latch mechanism. Thought it was one of those B pillar issues until I finally sat in passenger seat with someone else driving. Funny how sound bounces in a car.

Our 2013 RX450h (made in Japan) have 2 rattles (glove box & somewhere in driver door). Lease returned.

2015 RX450h (made in Canada) no rattle so far at 500 miles.

2015 RX 450h that i've had for 16 months (5500 miles). No rattles. Made in Japan of course (as all hybrids were at that time).

13 rx
 

13 RX bought two weeks after release in May 2012( 3 1/2 years old),35,000 miles; not ONE squeak or rattle or failure of any part; does not get better than this; first new Michelins 2 weeks ago!!

So, we went t the dealer today about the driver's door and steering wheel squeak. The door rattle ended up being a water bottle in the door storage area :sad: :egads: and the steering wheel was lubricated as it was not squeaking today. Glad there was nothing serious wrong and that all is well with our RX but we both feel kind of silly.

The good news is we had all three wiper refills replaced for $25.00 including labor.

While I don't have a third gen I do have a 2009 that was built in Canada. Not a squeak. Very happy as I love my audio.
