I got almost the same indications that something was wrong on my GS-450H 2007 lexus. It started almost a year ago with an indication "Check Hybrid System". I went to Lexus and they erased the indication, with their electronic device, saying it is nothing and I should n't worry about this. But should I get this indication again I should contact them. I not only got that indication but also for small time intervals the other indications "Check ERB. check VSC". I went to Lexus and told them, they erased it again and said they would contact Lexus Japan to check if I was covered with a warranty. The indication flashed again and that was when I was on vacation in August, but in the beginning of September as I got back and organised a visit to Lexus, the indication dissappeared by itself. I felt happy but it came back a few days later. The car was more or less working properly, despite the indications. Today I took my car finally to Lexus where they gave me the code POA 7F BATTERY PACK DETERIORATION and told me I was not covered by warranty despite the fact that I only have 100.101 km and less than 8 years of ownership, whereas the guarrantee is for 8 years and 100 K miles. Does anybody have any advice outthere?
