Happened to me tonight ... drove 10 miles .... watched my son's basketball game ... about an hour and a half later I started the car and it died ... tried again and started right away. This has been happening for about 6 months and always as described above. I've discussed it briefly with my SA but have not taken the car in.

Happens occasionally, not worth a trip to dealer,

He had to change one on another F90 as it happened way too often. Apparently the issue still remains and the customer is trying to lemon law the vehicle. Fuel pump is not an easy change either as they have to take out the back seat to get to it, sounds like more than one day of work. I don't mean to scare anyone and I'm no expert, but it's worth sharing. I have no performance issue with my vehicle when it happens and seems like it's only at start up. It doesn't happen often enough for me to bring it in and go through the hassle. Perhaps have them check it next time you're in for service. However, apparently the issue is very common so it wouldn't surprise me if they do a recall. |

I was wondering about this myself. I'd say it happens about 1 out of every 15 starts for me. Like others have said, its not worth another trip to the dealership though.

Still not acceptable and some may say embarrassing on a 125k car

I had this issue. They replaced 2 High pressure fuel pumps and that still didn't fix it, so they replaced a low pressure fuel pump. I was told to run 2-3 tanks of gas with NO ethanol and then back to normal. hasn't happened to me since.

How long was it in dealership for the low pressure pump replacement? Do you know if the back seats had to be removed?

Same here. Also seeing multiple Cranks before starting as well as it starting, then sounding like it’s about to shut off and catches itself and stays on. Service tomorrow and will see

Happened to me three times today alone . Before today happened less than 5 times. Not sure if it was the fuel that I last used at the last fill up (Shell 91 octane, best we got here in Cali)
