Last week my 08 GS350 started and when I went to back up I noticed the Power Steering was very stiff. I got 2 houses down the street and the "check charging system light" came on. I turned the car around. As I was pulling in my driveway, the dash lights flashed, the exterior lights flashed and my car died. I tried to push the button but there was nothing. The next day I put my battery jumper box on it and I could hear the normal clicking sounds. The voltage was all over the place. The car did start, so I disconnected the negative battery cable and it died. I tried to start it again and the same symptoms as the night before. I took the relatively new battery out and took it to be tested. I was told that based on the battery readings it looked as if the alternator failed. 7 volts and he said 1/2 of the cold cranking amp. He gave me a new battery. I had it towed to Toyota and purchased an original alternator from Hendrick Lexus in Charleston, SC. Well, the next day my advisor called and said the car could not see my key. Then said it needed to go to Lexus. She wanted the Toyota mastertech to check it. He told me it was the recall on the fuel pipe. The Lexus dealer said it was not. I then asked Toyota if they even tested the Alternator and they said no. I then requested it be tested. While I was waiting for a rental car they text me and said Oh, we may have spoken too soon, the charging voltage is unstable and it may be the alternator. That was my main complaint to begin with. We are now on day 3 and they are wanting to throw parts at my car. Now it is the starter they want to replace. They sent me a screen shot and it shows PO335,PO340,PO345, PO365, PO390 C1201, C1241, B2243. (see attached screen shots) Based on what I can find out online this is triggered by the low voltage. Nevertheless, the car still will not start. I was told Lexus keeps the work around to this a secret. I am a widow. I could really use some help on this issue. Has anyone experienced this before?

Toyota sent this

Codes thrown by alternator and battery change

 

I had my 08 GS 350 towed to a Lexus Tech (just started his own shop 3 weeks ago) and he found the starter connected was pulled so hard by the Toyota tech that it was broken. That explains the no start. He had the car running in less than 30 min. Just like brand new.
