There are 3 owner-reported electrical system complaints for the 2009 Acura TLin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The Acura key has a hinge on it with a release button and a spring where the keys open when the button is pressed and the key locks in place. The locking mechanism on the hinge failed. This means that when enough items are on a keychain on the key the weight will rotate the keys into a lever and pull the car into the off position on its own while driving on the road. My car has turned off without warning due to the key hinge lock failure on the highway ant speed and well as on bumpy roads and at stoplights.
AUDIO STOPS WORKING AFTER 2-4 SECONDS OF STARTING THE CAR. SPEAKERS POP AND NO AUDIO.
