Great info, SP3CTRYS.
My car is still in the shop so I cannot test any of your listed items. Something is wrong with my vehicle, they are claiming there is not, stating they have talked with Nissan and basically, come pick it up. My dogs and I have already been exposed to one environmental health hazard (mold), I can't and won't expose myself or my dogs to another (fuel while I am driving the car!).
The first time this was taken in, they explained about the overfill during fueling. So, I have not done that at all in the couple of weeks I had the car back before the problem started again. So backfill and pressure is not the issue in this instance. Also, when this started again after the first reported repair, the fuel tank was only 1/4 full, so at 3/4 empty, I would not expect pressure from overfill to be an issue.
This second even was worse than the first. Started on the weekend, by Monday was so bad I was getting headaches from the fuel fumes. The order does not go away, and gets strong. Rolling windows down did not really help. Problem does not appear to be related to sitting and idling, and while I was not on the highway, I was driving-not sitting-and still increasing fuel smell. And I 100% agree, there is far too much reliance on computers diagnosis vs real common sense trouble shooting going on in solving problems like this these days. We have become an ignorant society that is ponly going to become more ignorant as those skilled with the knowledge you are sharing, die off and move on down the road, no longer able to share their incredible knowledge.
My car is 6 months into my posession when this issue started. Only 15,000 mi and still under warranty, I also purchased additional warranties to cover the vehicle thru 100,000 mi. For me, this is ridiculous, I bought a new car to avoid the need to be in the shop every other week, and yet, here I sit without my brand new car and now a service department relying only on a computer, stating nothing is lighting up as faulty in their diagnostics, therefore no problem, comeand get your vehicle.
Yeah, no thank you! I'm not drving a fire or health hazard and breathing gas fumes while they wait for the lemon law to expire in this state at 22,000 miles. I'm 7,000 miles away from that threshhold right now and the way I put miles on the car,that's gonna get eaten up real quick.
Thanks for the input. I will surely pass it along. If you or anyone else has more to offer, I would gladly like to hear that as well.
Thanks so much for adding to the conversation. Its nice to hear from someone with the skills to troubleshoot instead of relying on a computer!
