Since a couple days ago I hear a slight crackle when starting up the car coming from the engine i think and then there is a grinding/scraping noise when I reverse out slowly or move forward. I can feel some vibrations under my feet. The grinding noise only occurs initially when driving out of my driveway etc. and then always disappears once I start moving faster. This all comes and goes. Sometimes I’ll hear nothing and later in the day when I drive again the sound will come back. Already took it to a shop and but couldn’t find anything out of the ordinary, but this time I was able to capture it on video at least.
When in D I hear the sound, and in park it goes away as you’ll see below. The same noise also came on when I aired out, and stayed that way until I aired back up. Never had any issues before regarding this sound. Nothing new installed recently either.
