Second time this happened, filling up from almost empty, get's around 3/4 full and the pump stops. I had the lock on to let it pump all the way full. Second time, different gas station. Is this a gas pump issue or something going on with the car? Just curious if anyone has experienced this too, thanks.

I had a similar issue. Mine was stuck at 1/4 though. After driving 100 miles it started showing full and got stuck there, never dropped. Sometimes it went to 1/2, 1/4 etc. of course I took it to the dealership. They found out the transfer pump in the fuel tank was malfunctioning so they replaced the whole tank as the part comes with it.

Just try it a few more times and if it keeps doing it take it to the dealership. They do a pretty good Jon at diagnosing to isolate the fuel tank problems.

Yeah, I have a similar issue. I thought it was just me being an idiot not understanding how to properly work a pump. Then I realized it's constantly happening... I'll add it to my list to things to get checked since tasansal got his fixed.

First two posts could be describing different issues. It sounds like the OP is saying that the pump kicks off when full, then the tank is registering 3/4 full. My main question is, did you engage the pump again to verify there wasn't back splash causing the pump sensor to shut off? If you are certain the tank is full, then the gauge is still reading 3/4, this is inline with what the second poster is describing. If you're just locking the pump handle and assuming that after it clicks off the first time your tank is full, it's likely not.

I found that pressing in the nozzle too much causes this (especially at Chevron). I lay the nozzle in without force and this rarely occurs now.

I too have issues with Chevron and our X5 (N55). It very rarely will take a full tank without shutting off 1-2 gal early. Without adding extra fuel, the needle wont' reach "F". I have to wait a few sec then manually pump in the last gallon or so. annoying but livable. Never had this issue on either E9X or previous BMWs using the same station near our house. Complained to dealer several times about it and they said nothing is wrong with the car.

Last Monday the pump kicked off and my gut told me it was not full.

Kept shutting off and I was afraid of spilling out onto the paint. Sure enough when I started the car it was only 3/4 full. This has happened more than once.

Thanks for the replies guys, will see what happens at the next refill. If problem persists I'll check with the dealer.

No, I didn't. The first time this happened I just assumed it really was full. The second time this happened I paid attention to the gas amount pumped and it was only 3/4, around $47 as opposed to full tank of around $64.

This has only happened recently, before these two instances the car would always fill up no problems.

I've been lazy to get the car to the dealer but so far the list is

1. high pitch electronic buzzing coming from the dash whenever the car is on, and it's been getting louder and louder since I got the car (even while stereo and ventilation are completely off).

2. Wind noise from driver window (more than any other car I've ever driven). From what I've read online, seems to be pretty common with new BMWs, especially F30,32,33,etc

3. Pump issue mentioned above

My 330 did the same thing as does my 435. A very simple workaround, assuming you are willing to hold the nozzle as opposed to a hands off approach. Just rotate the nozzle so that the handle is above the filler instead of below it. For some reason, that has worked for me for at least the past 12 years. When it clicks off, the tank is truly full.
