Hi everyone, yesterday I took my 2018 NX300h to the dealer for routine service. The car has 65k miles and has been running fine, absolutely no issues. I was shocked when the dealer contacted me that during their inspection, they saw that the transmission was leaking. Furthermore they said that there is no fix other than to replace the transmission.

Has anyone else encountered this? I searched, but have not been able to find any details on this, other than isolated cases about transmissions needing to be replaced on ES or RX models. Maybe I was just unlucky?

I've own previous models such as RX and currently have a 2023 GX as well. This really is leaving a bad feeling to me about the reliability of Toyota/Lexus vehicles now. I've also owned German cars (VW, Mercedes and Porsche) and never encountered a case where a transmission needed to be replaced, granted German cars had their own issues, which is why I went back to a brand I thought was more reliable. Attached is a photo my service advisor sent:

Any thoughts or comments would be greatly appreciated!

Sorry for the typo in the title it should be NX300h.

The transmission is still under warranty. On the NX300h, the transmission is considered part of the hybrid drive system which has a 8 year/100,000 mileage warranty. If the dealer won't fix it under warranty, contact Lexus Corporate for assistance.

Thank you! I will ask about this tomorrow and contact Lexus Corporate if needed.

I called Lexus corporate and asked about the hybrid warranty coverage. Unfortunately, the transmission is not covered anymore under the hybrid system warranty. They pointed me to https://www.lexus.com/warranty.

Unfortunately, I am 8 months outside of the powertrain warranty.

This single experience has soured my so far perfect experience with Lexus/Toyota. When it is time for a new vehicle, Lexus/Toyota will no longer be a default no brainer for me in terms of having a reliable vehicle that "just works" every time.

Keep us posted. I thought 6/100k was bumper to bumper. If my 2021 nx300h goes even within 10 yrs, I’ll post it everywhere, and send corporate Lexus a parting letter & never buy another “so called” reliable vehicle and never buy another Lexus !! My family, friends, neighbors, etc will know too!!! This is rediculous BS from such a “high cost, we’ll known, so-called reliable vehicle/company”!!! Trust me, if we can afford a Lexus we sure can afford “those other high mileage vehicles” that have a great track record
