NHTSA Complaint #11556998 — 2020 BMW X3

1. Whenever I refill my tank the car will start knocking. It will be only for 1 or 2 sudden jerks. I have tried every grade and nearly all the brands of fuel but its still the same. Even I escalated the same issue when I had my car service done. But to no avail. It happens when I refuel the tank. Otherwise, no issue to my surprise. I Need to know if it’s a known issue? If yes then why no one reached out to me to provide solution for it? Its been years i have tried to escalate it but no resolution. 2. When i use turn signals (either left or right) it start skipping click sound. even when the engine is ON and even when auto engine start is switched off. It happens not all the times but occasionally. I also escalated it when i went for service but i was told if its not logged in system then nothing cant be done. For both issues i dont see any resolution. First issue is way too annoying as sometimes i loose power to engine.
