Poll: Are You Having Issues With Capless Fuel Fill?
Sponsored Links
Last week we discussed how capless fuel fill has become more commonplace across new GM vehicles: currently, the feature is present on 26 vehicles in GM’s U.S. lineup. We also presented some comments from owners who have had trouble with the technology. This time around, we’re taking a more quantitative approach to better understand whether the issues are widespread, or whether a minority is simply being more vocal about the issues they have experienced.
And in doing so, we ask: have you had any issues with capless fuel fill in a GM vehicle? Cast your reply in the poll below, and feel free to elaborate in the comments section.
For more information on capless fuel fill, including a comprehensive list of every GM vehicle equipped with the feature, see this link: GM capless fuel filler.

ouside flap fell off inside. need to know how to put it back on.
2018 chevy malibu
The cap broke off and the car is less than a year old… this is simply an annoyance for a vehicle I paid over 80k for!!
2017 GMC Sierra just ran out of warranty in Oct. Right around Thanksgiving I notice that the fuel fill flap was staying open after putting fuel in period it now gapes open and the whole mechanism needs to be replaced. Estimate I just got less than 10 minutes ago was $530. What!?!?! For a flap dohickey!?!?! I have also had the issue where the fuel pump shuts off while filling. About a 1/2 gallon will be dispensed and then it will click off and I have to go start the pump again. I saw both of these complaints already listed so it’s not just me. But I wanna know where to get the $338 estimate for this flapper thing because I’d really like to save 200 bucks.
A little more background on my issue with 2020 Cadillac CT5. My only issue is a frequent inability to fill without shutting off. I get 100% of my gas at Costco. Never had a problem with my 2017 CT6, or 2014 CTS there. If somebody is using the same pump as me on the other side, you can hear the flow rate slow down, and then I have no problems. It is clearly the design of the fill tube and its inability to handle the faster rate.
My $338 was from the dealership.
Everybody needs to call in a complaint on this to get GM to pay attention. My oxygen sensor code 442 still comes in every half dozen or so fillups.
I’m waiting for a aftermarket to fix this without the capless idea. There is a capless neck aftermarket out there but looks like a big deal replacing it. Like dropping the fuel tank to get the big hose on, but not sure. Maybe a mechanic could give me some insight?
2017 silverado the spring or something broke and now the flap stays open.
on my 2017 gmc seirra ,the tank flap freezes in cold weather ,causing serious frustration at the pump .another enginering,marvel from gm .put a gas cap back on the truck . how about a recall,after all these trucks ain’t cheap .
Flapper is always filthy, covered with dirt. You can’t tell me some isn’t going in when I put the nozzle in. A vented cap would keep it clean and allow it to maintain proper pressure.
Bad design, should be recalled.
Does anyone know what happened to Dimepiece LA celebrity streetwear brand? I seem to be unable to proceed to the checkout on Dimepiecela site. I’ve read in Cosmopolitan that the brand was bought out by a UK hedge fund for $50 m. I’ve just bought the Dimepiece 90’s Cuffed Beanie from Amazon and absolutely love it xox
I have a 2017 Silverado z71. The little flap on the cap less filler does not close. I think the spring is broke. Went to the dealership and they said I have to replace the whole filler neck. $271 plus installation. Why should I pay for their poor design. Does anyone know of an old cap retro fit?
Replaced capless filler for my 2017 Silverado. Cost $416.38. The Chevy dealer wanted near $600. I will never buy another vehicle with such a bad design gas cap. For over 100 years a vehicle gas tank used a screw cap. At worst you would lose the cap and replace it for less than $10. Now, the with the capless filler, it collects dirt and water directly deposits into the gas tank, and breaks for no apparent reason, causing the pieces to fall into the fuel neck, clogging the the fuel neck so you cant fill your tank . So much for making a better mouse trap. What’s next? Re-invent the wheel?
I have a problem at times filling my tank with the spring on the gas pump handle getting stuck in the gas tank entry hole.
2017 GMC Canyon w/3.6 engine just started having trouble with fuel filling back in April 2021. Carlisle Dealership in Waxahachie Texas came back with a bad Evap. canister with no check engine light faults. Fuel fill problem did improve, however problem resurfaced. Very little sympathy from the service dept. Of course, they said bring it in with what I expect to be another underlining cause and cost.
2018 Chevy LTZ Z71 currrently has just under 16K miles on 9/20/2021. So far I’ve had more than a few issues with this goofy system. Fuel nozzle has gotten stuck twice and had to twist and reposition the nozzle until I found just the right angle to get the nozzle out. A real pita! Also, on 9/2/21, found my gas door open after parking in a hotel lot all night (No, I didn’t leave it open!). Not sure if gas was stolen or not, because I was low on fuel when I parked and checked in. Hotel manager advised they’ve had 2 recent reports of gas thefts from guests.
Worst issue… My wife ran out of gas while driving home in my truck from a meeting. She’d stopped for gas when the little fuel pump icon came on. When she found a station, the gas pumps were ALL “out of service”. Next closest station was 24 miles away. She ended up running too low, as info on dash indicated she had 13 miles worth of fuel and had 19 miles to go according to GPS Navi. She called for roadside assistance. They gave her an eta of 1.5 hours (this was at 2 AM on a dark stretch of Hwy! The AAA tow truc got there in less than an hour. T/truck driver asked her if she had the funnel. Search the truck, …NO FUNNEL!!! T/truck driver tried to use his large funnel, but it would not work with the cap less system. She had to wait 45 minutes for another T/truck which had a special funnel for the cap less system. This capless “CRAPFUL” system is for people that have no clue how to tighten a gas cap a few extra clicks and don’t know how to use the “cap dock” that’s built into the fuel door so the tethered cap doesn’t dangle. In other words, “clueless lazy drivers”. It’s going to cost me about $400 to have a “capped” fuel fill system installed on my relatively NEW low mileage big bucks truck. Should have kept my old 91 454 SS. GM, stop making changes to perfectly good systems on your trucks. If lazy, clueless people can’t read an owners manual, don’t know the precautions of a closed loop system, and don’t know how to properly tighten a gas cap, then perhaps they should reconsider their vehicle choice or just call a cab or uber. If it ain’t broke, please stop “fixing” it. Just because the blue oval brand did it, doesn’t necessarily make it “a better idea”. I’ve been buying & driving Chevy Trucks since my first vehicle when I was 17. An 8 year old 1949 Chevy 5 window 3100. Paid a lot for it ($850), but it was a perfect first “car” for a 17 year old and never gave me a bit of trouble. Since then I’ve owned 19 Chevy trucks! 13 brand new ones and 7 preowned ones. Love my Silverado, but please give new age engineers more time off.
I have a 2018 Silverado 35000 miles but 3 yearwarranty has run out ! Check engine light came on ( solenoid ) gas flap shutter not working properly they say probably a mouse chewed the wires 🙁 really ) poor design ! Remote start won’t work with check engine light on !
If i had known about this poorly designed gas fill with no gas cap, i would have kept my old truck.
2020 Silverado. It has tripped the ecu saying the gas cap is lose or problem with your fuel system. Plus’s I always have issues with the pump shutting off. I never over fill. When the pump shuts off I’m done. I can’t believe you at gm are trying to put this back on the user’s.
