Has anyone with a 2019 Forester had any issues when filling up their gas tank? Specifically, the “clean air sensor” that stops the pump from overfilling your tank cutting off the flow of gas way too soon?

I’ve noticed that when I fill up my tank, if I place the gas nozzle all the way in, the pump shuts off within seconds of starting. However, if I pull the nozzle out about half way, it will continue to pump properly and seems to shut off at the appropriate time.

I have had that issue not only with the 2019 forester but, with any other car as well. My opinion is that the gases in the fuel tank are been pushed out/displaced by the fuel causing the nozzle to trip when it is all the way in.

I do not experience this with my Foz since I purchased it. I put the nozzle all the way in, it fills up...it shuts off...I leave it in 10 seconds like they say to allow all gas to drain out of the nozzle and I'm done!

No problems with mine, either. This sounds more like a nozzle related problem. Sometimes the fill tube angles are a bit of a problem but weird shut-off problems tend to be related to the way the springs/gaskets hold the nozzle, maybe flow rate, etc. We've had cars that seemed a little more susceptible to problems but generally turned out that a given pump at the local Costco caused problems with multiple cars because you'd see numerous people having problems at the same pump.

I have only fueled mine 2x without issue. The only "problem" I have noted is that the gas tank is small, only 16.6 gal US. My Legacy which I traded for this car held 18. Less than 17 gals seem too small to me. I realize that I could not go 500 miles without a personal bio-break, but the car would even let me try.

I am having this same issue with my 2019 Forester. I have noticed that is also progressively getting worse to the point where the pump stops 15+ times before reaching 10 gallons. Took it to the dealership and they say they cant find any issue with the car. Do you notice this issue more so when you're fueling from about 1/4 tank or lower? (Dealership tried putting gas into the car from 3/4 tank and had no issue). Did you ever find a solution?

Unfortunately I traded my ‘19 for a ‘20 and haven’t had any issues. What I did notice was it was specific to a few brands of gas stations that use the same type of pumps. I’m not experiencing it with the ‘20 even though they should be virtually the same. Maybe you can let your tank get lower and have them try to fill it again. Or ask one of their service techs to go with you to the gas station and you go to a familiar gas station to fill it?

I can say from personal experience it isn’t just Subaru vehicles that experience this behavior.

I had it happen quite often on my BMW 328 E90 series convertible, but I haven’t experienced it much on my 19 Forester. I’ve found that once you learn exactly how to insert and angle the nozzle while filling the tank, the behavior goes away.

However, in states (CA, for example) that have the nozzle “hoods” to eliminate fumes escaping, it might be different. When driving my motorcycles thru those areas, I always had to manually retract an hold the hood in the retracted position with my free hand in order to fill my bike gas tank.

I have just recently noticed the same issue with my '19 Forester... The gas stops fueling way too early and had to keep on pumping...

Same problem I have on my 2010 BMW R1200RT motorcycle. It's a pretty common issue on motorcycles and certain cars/fuel pump combination. Some pumps are just way to fast, and/or the flow is just not set right and it triggers the pump to shut off.

Much appreciate your response...I don't mind pushing the trigger few times but I just don't wanna overfill the tank...

We solve the problem on our motorcycles by not pushing the nozzle all the way into the tank, you might want to try the same thing with the car, pull it out like maybe 1/2" / 12.5mm.

I should add that if you look at the fueling nozzles in California, you see the big rubber boot! It pretty much prevents you from pushing the nozzle all the way in like other non-California states.
