Hi please help I have a 2004 TL auto with Nav

I was im a minor fender bender with my sisters car while parking, and since then my car has had intermitent issues, today for instance driving home 8 miles my airbag light kept flashing not long just on then off, also followed by the battery light flashing intermittently. When this happens the car stutters drivng it doesnt want to shift its hesitant, sluggish amd scary to drive. When I replaced the battery in december issues went away just up until last week now.

Last December i replaced my second bad battery within 9 months and replaced the alternator before this issue arose around 6 months ago.

The issue didnt present itself until the lil fender bender just driver side bumper damage thats it, no airbag deployment it was pullmg into my driveway. I know battery light on means alternator isnt charging but it doesnt come on all the time, im lost here and cant figure out a resolution or even a good way to identify, isolate,eliminate.

Any suggestions please advise if this is in the wrong area my dearest apologies.

check your battery connections, possible that they may have gotten loose from the collision.

you would be surprised what loose battery connections could alter how a car acts in many ways

Did that, the car hesitates when this happens too, revs go higher car wont accelerate well at all. Have replaced the battery in december, the alternator was replaced 5 months ago but still the battery light will go on intermittently while driving

Check the battery cable themselves for corrosion
