“Re: NHTSA 14v053000/hybrid propulsion system...I did not receive a recall notice in the mail. My daughter owns a new Prius and she did not receive any notice either. My car engine did not shut off but my daughter's engine has shut off. You should ask Toyota to show proof of its recall mailings. I'll bet the farm that they can't.”
