Acura RDX 2018 here, about 60K miles. Started "power cycling" when put in reverse. The infotainment system reboots, the engine kinda sputters; when I release the brake pedal, the car noticeably jerks.

I recently changed the battery. I don't think it's the cause: the car starts just fine.

I tried googling this symptom, but did not find anything similar. Any pointers before I put myself at the mercy of a dealer? Any help will be appreciated!

 

When was the transmission last serviced? 60K is usually time for trans maintenance.

 

It was the battery, it was a bit loose.
