Am starting to see some 100k preowned come in and even one at 150k. Do we think they will get to 200f

 

Depends if some take care (change oil every 5k change transmission or differential oil) maintenance car is a key.

 

I remember when cars from the 70’s used to have an accepted upper limit of 100,000 miles as an obtainable goal, but I would say, any modern vehicle, with basic prescribed maintenance should achieve 200,000 miles or 15 years no problem.

 

Easily…newer cars can reach those numbers no problem!

 

I've been asking myself that same question, every since I purchased my 4cyl TURBO 2020 NX.
Mine has a 4cyl turbo engine (8AR-FTS). Can this engine last upwards of 200k, 300k?

 

I am hopeful it will. Mine's got 63,xxx K Miles on it and it's "like" new.
But if you hang out on this site long enough you'll see more than enough mixed reviews to question it all. It's a "new" engine for Toyota/Lexus, which of course isn't something Toyota is known for. That tends to make people nervous, but truthfully the 2.0L 8AR-FTS is in a number of Lexus and Toyota. I found this a good base read on the lineage of the motor it is based on the AR motor which was introduced in 08 and put in vehicles like the Highlander. I'm certain it's reliable. There are folks getting 300-350whp out of these engines easily. It is also worth mentioning these turbos are seriously detuned. Toyota does have history with vehicles/engines being detuned/neutered to provide even further reliabillity/longevity: i.e. 4.7/4.6L V8's known as "Lazy V8s" capable of producing 30-75 more HP,. But, as they come from factory neutered, they reliably hit those 3-400K mile numbers you see from the ol' Tundras.
The IS200T folks seem to enjoy pushing the engine with tunes, including D3 Performance's tune - I am interested to see what happens as these engines see more development... That said, it does seem to be slow. I would consider a tune and larger turbo down the road, as the turbo is very tiny on this car, I see folks mentioning barely hitting 15 PSI throughout this site.

Luckily for me, until the '22 highlanders or possibly the '23 Grand Highlander are being turned in for 3 year lease returns, the NX will continue to be the wife's daily and I won't do anything but build a to-do list :P

Here is one that has just over 200k miles. So it can happen!

 

Interesting history. Looks like it was always serviced at a Lexus dealership! The owner did a lot of miles/year but always brought it to Lexus for their 'recommended' services.

 

Any car could get up to 200k if you spend enough money on it. The turbo is the weak link in this car, it usually goes between 100k to 200k.

 

If proper maintenance is done, I don’t see why not..

 

I just retired a 2006 Nissan Altima with 278,000 miles on it. Religious oil changes, changed ATF fluid as needed, as well as other routine maintenance--that was it.

If a Nissan can go to 278K, I have no doubt a well-maintained Lexus can easily get to 200K.

 

Our 2004 RX330, was over 265k by the time we traded it in. After about 120k I did most of the minor maintenance, brakes, alternator, oil and such. Ran full synthetic after 120k, (royal purple) and factory oil filter every recommended oil change. Never had to do the transmission fluid, or shocks(it also had factory assist air suspension). Took it to the dealers for timing belt/ water pump and spark plugs when recommended. When we traded it in the inspector from Lexus wanted to park it on the show room floor, because when he started it up, couldn’t believe it had the number of miles on it cause it still ran like brand new. I bought my current Nx with about 106 k on it and hope it will last at least the next 5 years, following the similar maintenance routine of our RX.

 

Wife drives a 2016 NX200t. She also has a 2005 Saab 92x (rebadged WRX) with a 2.0L turbo. We replaced the engine with a JDM EJ205 @ ~ 190K but kept the same turbo. Car still runs fine at ~210K.

Hoping her NX lasts until 200K.

 

What!

Any evidence to back that up.

Have not seen any information on any site of a blown turbo at any mileage.

 

Agree, I haven’t seen anything to that effect either…
