problem #1

Sep 142015

GS 450h 3.5L V6

  • Automatic transmission
  • 97,000 miles

I took my car to the Lexus dealer after a basic routine maintenance and a warning light came on with the description "Check Hybrid System".

I let them know of the problem before even moving the car. They took it back and ran a diagnostic on it, the car came back with trouble code: P0705, they told me that the transmission control module needed to be replaced; parts, labor, and tax would cost $1300. Note: They did not replace the part yet.

They cleared the code and ran another check, the car failed to bring up the code again, till a week later. They told me that it was an intermittent fault and that if happens again that they will need my car for a few days to run some tests.

I've been monitoring the hybrid system and everything seems to be working perfectly.
