Hello, So i have a 2007 Tl type s (automatic). So I was driving and all of a sudden my car would jerk and the radio shuts off. Then the radio would turn back on and it would be driving normal again. So i'm not sure what happen, it felt like the car was gonna stall out.

 

I would start with the battery connections, ignition switch, grounds, etc.

 

Does your engine shut off? Dash lights flicker when it happens? Navigation restarts? Feels like it was what I had at the start of my problems. I recently replaced my alternator.

Do what I Hate Cars tells you, he's informative.
