The engine control computer software computer has programming error which can cause the exhaust VVTI locking pin to temporarily get stuck. They will fix it with just software update, I believe this is for both 2.5 TX, RX and NX 2023 models for now.
This is campaign which is one level higher then TSB, but isn't official recall, but dealers will be reaching out today and should be in your app.

This is important as if it locks it should disable with MIL into limp mode, but if doesn't you could end up with serious engine issue.

 

Hybrid models affected?

 

2.5 is in the 350h only.

 

Got a link with details? Google has failed me.

 

Just found this campaign in the Lexus App on my phone, it's in the Health section. It pertains to the 2023 RX350 non-Hybrid as well as that's what I have.

 

Sorry I meant 2.4L application, anything with the 2.4L turbo. It will show details in your app. What is strange is Toyota Highlander with same engine had this is listed on 2023, not sure why they waited for RX or maybe only applies to 2023 RX.

Yup, it's on the wife's app as well for the 2.4l turbo.

 

Since ours is in the service (non hybrid), they're addressing this service campaign today.

 

I also want them to do that other TSB for hesitation, as I only get it from stop, but if I am turning in front of traffic it almost gets me at times. Yesterday I literally slammed on pedal heard gas pedal click and then it went.

 

I have it in the app also for the 350. The dealers are going to have a flood of phone calls today from this, seems like they should stagger the notifications.

 

I got a 200 mile trip close to our dealer at the end of October. Going to have to see if they can squeeze it in for a quick service before I pick up Mom at the airport. I would think it takes less than thirty minutes to do once the car is in the bay.

 

@John89, would you please let us know if they fix the hesitation issue? I have the same problem. I will the ask our dealer about the TSB as well and post any results.

 

I will just got get the time to get back there for both updates, it only at complete stop which is why it isn't really noticeable unless your turning in front of upcoming traffic and have some gap. Otherwise at any rolling speed never an issue.

 

Nothing in the app for our 24.

 

Maybe the fix is already there. It was first discovered in Toyotas last year.
