Hey all I have a 2015 nx200 with 235,000 km on it and I want it to last well into the high 300s maybe even break 400 km

What are you guys seeing on what to watch out for and what to do (and not do) to get her there.

I've replaced the wastegate actuator, rear shocks were just replaced, planning on replacing the water pump proactively, I run Shell 91 gas in it - in Canada all gas has ethanol, I normally do my synthetic oil changes with Mobil 1 0w-20 every 7000 to 8,000 km but my last oil change I just put in 25,000 km Mobil 1 and I'm at 10,000km so far and sent the oil out for analysis to see how much it's degraded. I've changed all the fluids (tranny, diff etc) at "general vehicle recommended change times" as I do not believe in "lifetime" oils.

Anything else to get these to run to 400,000km? I'm taking on this challenge!!!

 

The number one issue that will affect the long-term life of your vehicle, is your driving style. Do you drive it in sport mode all the time getting the engine up above three or four thousand RPM? Zipping through traffic? Do you tow anything ever? Load it all the way up for a camping trip??

Or do you drive conservatively? Mostly freeway? Or drive in a state that salts the roads in winter?

As long as you use quality fluids and change as recommended, then it's all about your driving style and environment, i.e. how hard you push the machine.

 

Have you had any issues with your head gasket — seepage or leaking?

I’ve heard the inaugural first year of this model NX to be way more solid as they come for first year models.

The fact that you have a 2015, tells me you’re well on your way to making it to your goal of 400k km (approx. 250k miles).

If the CT200h can make it to 1 million miles, surely the NX can get to 250k miles.

I do believe there’s some NX owners out there that have made it to atleast 200k miles, maybe even beyond that.

Happy trails — Good Luck and keep us posted

 

Good point. I've started to push the machine harder, especially now that I have a bottle of redline fuel system cleaner in it...

I tend to drive into sport mode in the city but I don't really bring it past 4,000 RPM because there's no need to. It's a 50/50 mix of Highway and city driving on the highway every time I give it all the way once to just clean out the valves... But now the car is getting up there in age I've stopped doing that except for now that I have the bottle of red line in there.

I and in an area where they definitely use salt and brine so I take the car to the under spray drive-thru every now and then and make sure to get it oiled every fall with rust cure wax based oil

 

Well that's reassuring. I have not had any head gasket leaked that I can tell there's no white smoke coming out the back but I guess it's something to keep my eye on. Is this a common occurrence with these engines?

I do have an odd shudder when accelerating from a stop in first gear between 3,000 and say 5,000 RPM when the torque is the highest.

If I don't accelerate hard it doesn't happen but the whole car shudders/vibrates.

 

No, not common, but I have heard of it happening and if your NX is good, then I wouldn't worry about it.

Not sure if this is related to your problem, but maybe helpful?

It's from this thread:

Thanks for sending but mine is more like a full car violent shudder. I did hit a rail road REALLY hard while braking to the point where my head got the roof and I thought the dash was going to fly out at me. Surprised the air bags didn't go off

Imagine flying down a hill on a back road and at the bottom there is a railroad, but the railroad pavement is raised... Imagine a "check mark". Worst case scenario.

I thought for sure the oil pan would have been broken but everything was "fine". Motor mounts are fine too. My hypothesis is something wrong with first gear or perhaps the transfer case from that blunder I did. But I recently tried to accelerate really hard in reverse and nothing happens so perhaps it's not the transfer case

 

Wow -- that is quite the "check mark" and glad to hear everything was "fine" afterwards.

You've been taking good care of your NX and should be able to enjoy it for many miles and years to come as long as you keep up on reg maintenance / service intervals and after taking care of the "shudder".

Any updates on that?

 

I have a 2015 NX that JUST had a head valve gasket leaking on alternator and the drive belt, so all this had to be replaced. I took the car to the dealer for an oil change, good thing I did because they discovered this under the hood. I'm actually still waiting to get my car back. As soon as I pulled off the lot, every engine warning light came on so TBD on what they missed.

I have 159,000 miles. It's paid for and my kids have junked it up so bad that it will absolutely be my daughter's car when she turns 16 in 5 years

 

Yes actually I do have a small update that I discovered yesterday! I put the car in second gear driving slow and accelerated quickly and the shutter happened then as well so it's not just first gear I thought maybe first gear was screwed but it's not just first gear. It happens around 25km/h to 55km/hr under high torque load

 

I’m glad to know your NX lasted to almost 160k miles before the head gasket became an issue.

I was actually looking at a 2015 for my daughter last summer and on the CarFax it mentioned what mechanic the car was serviced at so I called that shop asking about the NX. He was able to tell me there were signs of seepage on the head gasket that would have to be addressed. Looks like that owner traded it in/got rid of it rather than fixing it up and keeping it. Everything was immaculate and well taken care of but I didn’t want to take on the cost of that fix.

The NX will absolutely be the perfect first car for your daughter!!



Uh-oh — well, keep us posted on this as well…

 

Take a look at carcarenut youtube channel, all the issues he sees with Lexus and Toyota have to do with the 10k mile oil change interval, he recommends a maximum of 5k and actually says to do 3-4k oil changes if you really want the car to last, because the turbo really cooks the oil. I have done 5k for the life of the engine, but am going to drop it to 4k now that i'm at 100k miles. I do a lot of towing with my car though.

 

It took me a LONG time to accept the 'recommendation' to go 5k between oil change. All my life I've been doing them at 3k. Finally, I was convinced mainly because of the hype about "synthetic".
A couple of years later, I then read about some saying that the turbo is harder on the oil, and so, now I am back to my 3k interval.

Now, for me, it's a no-brainer:
1) Peace of mind.
2) Not expensive at all (I but the 6 1q jugs of Mobil-1 at COSTCO when it's on sale, usually about $33 for 6q). I buy the OEM filters in mail-order, perhaps 10-12 at a time, costing about $4/each.
3) I DO IT MYSELF, and I know it's getting done R I G H T. I let the oil drip, drip, drip from anywhere from 30m to 3h while I tend to other things at home.

 

Thanks for posting this reminder of your OCI routine and what products you use.

I might add that I think you said this was the easiest OCI on any car you've ever owned !!

Curious to know what your mileage is at now?

I have also stocked up on OEM filters during sales so...

Just a reminder that Bell Lexus (AZ), Treasure Coast Lexus (FL) and Prestige Lexus (NJ) next sales should be around Black Friday and Christmas time.

With Free Shipping and No Sales Tax for out-of-state customers, you just can't beat those prices !!

I will edit this post and provide part number for the OEM filter once I get home

 

Sorry, but get rid of it.

At 200k kms my 2015 NX 200t started costing big bucks.

2nd rear main seal leak. Chronic battery issues. Interior trim, front arm rest needing replacement. Lexus standard service increasing to 4 figures. Creaky sunroof (although problem across all Lexus tilt and slide moonroofs), Rotors needing replacement etc etc.

And yes, serviced by Lexus from new and had all the service bulletins like wastegate actuator done early on.
