Brushing your teeth and not being among the 80% of people who are overweight is good advice too. It has nothing to do with fixing a broken thing, which is the topic of this thread. Start your own "Good Advice" thread and stop wasting people's time in this one.

 

We're all just trying to help and you're losing control of your attitude. All I'm gonna say is use a bottle of fuel cleaner and maybe it'll help you feel better...

 

"Do you normally take the opportunity to pat yourself on the back about how superior you are when people ask for help repairing something that is not functioning correctly? Start your own thread titled "Look How Great I Am".
No need, I already know I'm great.

Per your OP
"The Mazda CX-5 sometimes stutters and dies randomly, and it seems to coincide with having less than 1/4 tank of fuel left"
Had you kept a 1/4 tank or more of fuel in your vehicle, as I suggested, you wouldn't have had the issue.
You may want to loosen your hat a bit as it appears to be affecting your disposition.

 

I clearly stated the nature of a defect, so "help" would be addressing that defect. My attitude is perfect, though words don't convey attitude online efficiently.

The defect would remain regardless of what volume of fuel one puts in one's fuel tank. Let's explore the logic of your "help" by using an extreme example.

Me: The car ran out of fuel when I had 95% of a full fuel tank.
You: Keep the car at 98% full, and you won't have any problems.
Me: Yeah, but it's supposed to operate using all of the fuel.
You: Keep it at 98% full.
Me: Is this a real conversation someone wanted to have?

Most folks just don't say anything when they don't have the expertise on the topic at hand. Others feel the need to demonstrate they have no expertise.

 

Did you even think to correlate that maybe there's stuff in the bottom of your gas tank that causes the issues you described below 1/4 tank? It could have caused some stuff to get sucked up into the fuel sending unit. Or perhaps the fuel filter is getting clogged, albeit rare on newer cars. Heck, even try to do an italian tune up on the highway. Everyone is trying to make suggestions without being there in person based on what you have described. It's hard when someone's feelings make them upset at everyone instead of trying to work out the issue by communicating like adults...

 

HAHAHAHAHAHAHAHA Good call Lobstah!!!

 

Once again, your original post:

"The TLDR description of the problem is that my 2017 CX-5 appears to intermittently have issues pumping the last 2 or so gallons of fuel from the tank. The Mazda CX-5 sometimes stutters and dies randomly, and it seems to coincide with having less than 1/4 tank of fuel left. It had only done it twice before, once with my wife, and once with me. After tallying the fuel put back into the Mazda, it appears to not be accessing the last 2 gallons of the 15-gallon fuel tank, and only occasionally, as I've pushed the fuel towards empty way more than that before (up to 14.5 gallons)."

My post stated I never let a fuel tank go below a 1/4 tank as the gas cools the fuel pump and helps keep it from picking up tank contaminants.
If you compare my post logic to what you actually posted, it would have "fixed" your issue.
Your 95% - 98% argument is a fictional figment of your skewered imagination.

And by the way EFI motorcycles, like cars and SUV's, do not have a petcock or a reserve.
Like I said, loosen up your hat.

 

To be the devils advocate, as I often seem to be in this forum, keeping the car at 1/4 tank or above is a bandaid, not a solution to what he asked. As he no longer has the car, the point is mute anyway, but it seems the best thing he could have done was a DIY R&I of the fuel pump (and maybe even replace it) and to take a look in the tank to see if there was debris in the bottom. This was suggested by others, but I can understand the frustration of the OP being told they should just "keep it above 1/4 of a tank" when they would like to be able to run it dry if they want, if a solution was available. Others have posted they had the same issue as the OP so it isn't just one car either. As I said previously in the thread, I have run both my 19 and 21 CX-5's down to "0" on the miles to go counter and never had the issue described.

Good luck to the OP and his Tesla.

 

My saying keeping the tank at 1/4 or above was a valid fix as well.
He clearly stated he never had the issue unless he or his wife went below the 1/4 or 1/8 tank fuel level.
However, as he and you stated, he got rid of the vehicle, and we'll never know what the reason for his issue was.
Though I would suggest running his fuel tank to near depletion on what appears to be a regular basis by his description, certainly didn't help.
Him coming back here to chastise other forum members after the fact was a pointless endeavor on his part.
As it is yours in defending his behavior.
I would be interested in his experience with the Tesla, especially if he runs down to minimal charge frequently, which is indicative of his past operating procedure.

 

Couldn't disagree more. Not saying anything is even more supportive of the bad behavior seen on this forum so frequently.

I just got back from filling my 21. It had 20 miles of range(below 1/8 tank) when I got to the station. No issues whatsoever with stuttering as the OP and others have posted so obviously there was an issue with his(and the other 2 posters in the thread with the same issue) and we still don't have a solution or diagnosis... Filling at 1/4 tank isn't a diagnosis.
