“Hi there, My car has been to the Acura dealer multiple times for the same issue, and I'm hearing that alot of other Acura TLX owners are having the same issue. My car screen will randomly short, and can just shut off. Sometimes when I'm backing up, the screen will freeze and i wont realize that someone is walking behind the car, almost causing me to hit them. The audio system also can make weird crackling noises as well. There are definitely some safety features that shut off with the screen, though i cant pinpoint them exactly.”
NHTSA complaint #11530116, filed 2023-07“How Acura Lost my Business The fact that no one from Acura will take responsibility for the ongoing issues has reaffirmed that my long-term commitment to owning Acura’s is over.

The passenger front seat airbag can deploy prematurely in an accident, and cause an injury. …”
