Q: Grinding noise when starting up.

asked by on September 15, 2016

I have a grinding noise that only lasts a second when starting up my vehicle. It only does this when the vehicle has sat for about 6 hours. I have replaced all mounts and still does it. It also makes a grinding sound the first little bit when accelerating.

My car has 127000 miles.
My car has an automatic transmission.
