Use your warranty!!! This will not "fix" itself. I think your car has a gas tank venting problem.

Your dealer is pumping smoke up your butt. It’s a well known issue. You are not alone. Keep pressuring them to resolve. Threatening lemon law return might help. It’s way to find it’s a widespread problem. Just Google 2017 Malibu fuel tank issues.

We got the same problem with 2017 Malibu 1LT (13 gallon tank, 1.5L engine): 1. After fill-up, the gas gauge shows ~1/4 tank short of FULL 2. When the gauge shows 1/4 tank left, it only takes 5-6 gallon to fill up. IT acts like the car has only 8-9 gallon tank instead of 13 3. After our initial complaints, Chevy dealer re calibrate the vehicle and that only yielded mixed result: sometime it works, other it did. I was told there is fuel tank/fuel sender problem (mechanical interference) 4. We are going back for gas tank/fuel sender replacement

@ss20toto did the new sending unit fix your issues? My 2017 malibu is at the dealer now getting the sending unit replaced. This a well known issue and im shocked gm hasn't addressed this with a recall.

So the dealership put a new sending unit and tank in my 17 Malibu. After I picked my car up. I went to the gas station and did a slow fill up. After the pump would shut of I would pull the nozzle out for a few seconds and then put it back in and fill until it shut off again. I repeated the process a round 5 times. Each time waiting for the gas to settle into the tank. I now have a full tank and my app shows full at 13 gallons

It is sad to day my local Chevy dealership has not helped resolving my 2017 Malibu fuel gauge problem. What they have done to my car:1. First time: re calibration of software to show Full when fill up (cheating only, if I drive 5 miles, the fuel gauge drops to 7/8 tank) 2. Change Fuel sender:: same result 3. Re calibrate software again. This time it got worse: when full, the gas gauge is 1/4 tank off 4. Forth time: change fuel tank, fuel pump, fuel sender, re-calibrate the system again: no help. basically the fuel gauge has 8 divisions total. It seems like each division is equal to 1 gallon. Or another word, this vehicle acts like it has 8 gals total instead of 13. I sent the vehicle away for last 8 months. So now I have it back and will complain again. What a incompetent engineering organization (GM). The incompetent dealership does not help either. How on earth that a vehicle ,that barely sell , has 3 gas tank sizes and they could not even design/calibrate them right. BTW, the radio also die at 0 degree F. That defeats the backup camera feature (safety?)

I have the same problem with my 2017 Chevy Malibu. Took it to the dealership twice and they said there is no issue or recall. Almost impossible to get more than 9 gal in it even when completely empty. Very frustrating when it has a 13 gal tank.
