Hello, there,
Here is the weird thing that happened to my 2008 honda fit and hope some more inexperienced people can help me.
Recently it started to refuse to move forward at a stop sign after fully stopped. Last several times, I just turned off the engine and restarted the car. Once moving, it seems to keep going though jerking happens.

Today, it happened again but I did not turn off the engine. I opened the hood and felt the sound was not right (please see the attached short clip 1); I came back and turned off the air conditioner, and the car became quiet completely. Seems the ongoing sound was just for the air conditioner but not moving tires forward. Then, I started the engine and this time, the sound was completely different (please see the short clip 2) and seemed to become usual with mechanical parts running though I was not sure.

I know I have to repair this before something worse happens. However, could anyone tell me possible reasons before I go to a dealer or repair shop? How much would it be to repair? I know everything is expensive nowadays.

Thank you!
