Fuel and emissions issue

[flying68]

FWIW, I also have a 19 Escape work vehicle. I routinely top off and fill the max I can out of pure frustration from the driving range of the vehicle. I did the same with my 15 Escape and 17 Cherokee. I have yet to see any kind of issue or CEL from this, albeit I never top off that much with my personal vehicles as they always have a “normal” driving range. I will likely be doing the same with my 22 Ranger that will replace this Escape unless I have some issue from it. That’s roughly a combined 163k miles and 3 vehicles over 5 years, excluding maybe 25-30k miles in rental vehicles with the same procedure, and no issues.

Edited to include that the Escape manuals have the same verbiage, along with other warnings regarding overfilling.

I used to do 2 or 3 clicks on my '12 Explorer, ended up eventually having to replace the evap purge valve which sits in the engine bay. Pretty easy fix, but since then I only do a single click.

The '06 Murano we had was terrible with premature shutoff's do to a bad design in the tank and vapor control. It went bad gradually over time to the point where you had to manually control the flow at a low level to keep it going, problem is half the time, the gas flow would have to be so low it wouldn't click off and you would end up with gas spilling out the cap. Hated that thing. We were well past all the warranties by then and Nissan never issued a recall, but they had a TSB that called for replacing the tank, which would have been expensive.

Interesting. Maybe I was lucky on my few vehicles with 75k+ miles, will be curious how this 19 does. Different animal all together, but I did the same with my 07 F150 5.4 until 150k and never had an issue either. Not disputing the fact we shouldn’t do it, but interesting the issues are inconsistent.

The purge valve(mine is under the hood), will set service engine light and code. It usually is for a small leak. The valve gets stuck. I was told, one reason is because charcoal debris from the canister, due to people over filling the tank.

That is what tripped mine. It was suffering from rough starts after every fill-up before the code was set. Once I replaced the valve, which was back by the firewall on the top (easy location to get to) the starts became smooth again.
