poss warped frt rotors. does steering wheel shudders while braking
no but it has a grinding moaning sound when stopping.

I can sometimes hear the rumbling vibration when idling but definitely when stopped at a light with my foot on the brake
ok that makes sense ck your motor mounts they could be sagging or broken and the motor is sitting on the metal part of mount and causing vibration
just had them replaced hoping that was the problem?
ONE COULD BE IN WRONG OR LOOSE OR DEFECTIVE DOUBLE CK 1ST
Thank you having it checked again right now. Everything was fine.

The check engine light has been on, could a bad sensor cause these symptoms?
