disappeared. Saved over $1000 by taking charge of repairs. There was no accident involving this car. My understanding is following research into the problem that certain software removal tools could have cleared the battery drainage event. I do not know if lexus attempted this repair.

realize it is an older vehicle and computer chips could fail due to age but I wonder if this could be a design flaw of the fail safe accelerator assembly.
