2009 Pontiac Vibe 1.8l
I have a loud grinding sound like metal on metal on when starting my car up. Lasts about 1-2 seconds. Usually on a cold start. Notice it in the morning when going to work and getting off work.
It happens off an on randomly, not every day, but seems to be more frequent now. Did it twice today. Any ideas of what it may be? Kind of embarrassing when it happens and others are around. Car seems to run fine other than that terrible noise at start-up.
