Unusual problems wondering if maybe others are experiencing any of the same

About 1 mth ago now I noticed all my dash indicator lights all staying on even after the car was started and I was starting to drive. I ignored it because to me it was more of a distraction, then with in a week my car started making a grinding noise, whether my foot was on the brake, gas pedal, or just parked with the car still running. I could feel the vibration when my foot was on the gas pedal thou. So another week or so passed and I was driving and my car started sputtering like it was going to stop. That was it I called a tow truck, my mechanic changed the breaks not sure if that fixed the problem couldn't fix the dash lights, then when I went to drive it I close my door and the sound that tells you your door is not shut is now staying on as long as the engine is on! What the heck is going on with my poor car? I only drive locally no freeway driving at all.

Thank you for any insight before I shell out a lot of money at the dealership.
