Good morning Ralph ( and others ) ! My name is Allan and I am in London, Ontario Canada. ( between Detroit and Toronto ) I have had my QX50 now for approx. 3 weeks. I drive it daily and it is always in the garage. I would say that the fuel odor is there about 40% of the time. My wife hates all these fuel or chemical type of smells and when I first noticed it, I put her nose to work ! I called her out to the garage, and she noticed it immediately !! Obviously, you know about the TSB ( technical service bulletins ) on this issue and the repair process. I have always thought about recalls this way. If you have not modified the defective part, then are you not just installing a " new " defective part ?? So as you say, when they replace the o ring or whatever they replace on this fuel line, wouldn't it be with another bad part and does not resolve the issue. I am surprised that Infiniti ( being the high end of Nissan ) would not be anxious to keep the customer satisfied. This would be in the old days on how customers were treated depending if you bought a Chevy or a Cadillac !! I am sorry for all your trouble Ralph. Having your number, I will text you. Allan.
