Hi, I have a 2010 Lexus RX 450h with 110,000 miles. A few weeks ago I got system message telling me to check the hybrid system. I took it to the nearest Lexus dealership and they told me it was a bad inverter water pump so I had them replace that. However, it didn’t fix it and I am still getting the message. They said the next step would be to change the inverter, which they quoted me at 7,000-8,000 for. There is no other Lexus specialists in my area and all the local mechanics are telling me they don’t work on hybrid systems.
Ive been looking online for a solution as I am semi mechanically inclined and can do some troubleshooting myself. I have an OBD reader and I pulled of the code P0A93. When researching it online it seems like it could be a couple things.
After they changed the pump I noticed that the fluid didn’t seem to be churning like say the power steering fluid would, but I not sure if it just doesn’t. They also added fluid above the full line so I was wondering if that would make a difference. I also checked a few of the fuses connected to the hybrid system including the pump and they all look good. I also located the vents for the hybrid system and they don’t seem to be covered or clogged.
I just want a second opinion since I have hard time believing its a 7,000 job.
Feel free to ask me any questions, I would greatly appreciate any help.
