Yes it is the 2.4 turbo

I really wonder how many of those parts really "needed to be replaced." That's the kind of list you get when repair guys don't really understand the problem (which is not encouraging).

No, nearly the whole list is seals or one time bolts that you replace to take off the front engine cover to get to the exhaust cam phaser.

This is the second time in the shop for the same issues starting at ~3000 miles & again at ~5000 miles-Check engine, drive-start-control malfunction, system malfunction and other safety light malfunctions-very unfortunate. My vehicle has been in the shop cumulative over 16 days with unknown ETA for final repair. Frustrated and concerned to be having these kind of safety & engine issues on a brand new vehicle.

Yes. The Toyota Highlander owners with that same engine are experience the same problems also.

Same issues here, on my 23 RX 350 FSport. Now approaching week 8, awaiting repair. parts on backorder, and just received a few days ago.
Lexus confidence in the RX going forward is on shaky ground, with this engine....but yes, i'm certain that Lexus can/will repair.
I'm curious about how many parts will require replacement.
Can I trust this on road trips? I think not. I'll take my 200k mile GX on a road trip, before this '23 for now. Geez! Never thought I'd type/think this way.

I had the same issue , they drained and replaced the oil twice. 1000 miles later and have not seen the warning lights again.

I just purchased a new 2023 RX350 about 50 days ago.

Today, while merging on the freeway, heard a ding and then a warning light with the message "System Malfunction", visit your dealer.

I got to work and turned off the car and turned it back on to see if the message remained. It did not BUT... my odometer displayed 8,345 miles!!!

It eventually goes back to the actual miles of 1655 but very odd.

I turned it off again and back on and same thing occurs.

I have a call in for service but this is odd. Anyone seen anything like this before?

Read the other threads here - that's an ominous message.

I think the 8345 was the reading for miles to next service, not the miles on the car.

Yes read the thread titled brand new lexus rx350 has issues. My 2023 rx 350 with 3400 miles has been at my local dealer for over a month now for the second attempt to fix.They have been waiting for parts. They say parts are due in this week.

Thanks
I do see the little wrench icon - so that does make sense.

It's my first Lexus so still getting familiar with it and it's displays.

Yikes! Let's hope that's not my future.

Sorry you are having to deal with such issues.

Ironically, the reason I came to Lexus is my previous car (BMX X6 2021) decided to just slow down and STOP on a very busy express way with no warning of any kind. Very lucky to have not been seriously injured or even killed. After two days at the dealership, they couldn't find anything wrong. I got rid of it. So, I'm a little sensitive to system malfunctions!

Ours gave up at 590 miles. Sat from mid may till our buyback in early august. I was told they tried the big fix to no avail (we already decided to not accept it regardless of the progress after several months). good luck

I booked my oil change today, about 2K miles on the car. The dealer was giving a discount coupon this month, so why not try it if it might help.

Your error was from one of the safety features, it could have been it was raining or something on road got in front of sensor this is why it disappeared and cleared it self..
