Couple weeks ago, my Lexus hybrid system light came on. I took the car to a local Lexus dealer. They charged me $160 just to test the engine light and told me to replaced my hybrid battery for $6,700. I am so broke I declined the replacement. Last week, I opened the hybrid battery and tested all cells. Turns out all cells are fine. I reassembled the battery back in place and drove it for another week. Today while driving 70 mph on the highway the "warning hybrid light" comes on again including check VSC, check ECB. Does anyone here has the same problem like it do? I know the battery is fine. Could the battery converter causing this problem?
Any advise would be appreciated.
