Known Problems

The Acura 3.2CL may develop issues with the automatic transmission.

Rough shifting may occur, and the “D4” light and check engine may begin to blink. The check engine light will also illuminate, and OBD trouble codes P0700, P0730, P0740, P0780, P1768 and/or P1768 will be stored in the computer.

If the transmission shifts roughly, the failure is very likely mechanical failure of the transmission. If the transmission performs normally, a faulty sensor, or dirty transmission fluid may be the case.

In most cases, it is necessary to use professional diagnostic equipment to provide a diagnosis, and complete the repair.

The longevity of the transmission is dependent on strict adherence to the manufacturer's recommendation for ATF replacement intervals and procedure.

The 1998-2014 Acura TL V6 may develop issues with the automatic transmission.

Rough shifting may occur, and the “D4” light and check engine may begin to blink. The check engine light will also illuminate, and OBD trouble codes P0700, P0730, P0740, P0780, P1768 and/or P1768 will be stored in the computer.

The hood may flutter or vibrate at freeway speeds. Acura has made a revised rear hood seal available which should eliminate this problem.

A loud squealing noise on high mileage cars can be confused with a loose fan belt. The distributor should be inspected because it can seize, which can cause the timing belt to slip resulting in serious engine damage.

Some automatic transmissions have a shifting problem that can be corrected by simply reprogramming the computer.

The Airbag (SRS) warning light may illuminate due to one or more failed sensors. Our technicians recommend complete diagnoses of any stored fault codes because these sensors can be very expensive to replace.

A shudder or vibration may develop while driving at speeds between 35 and 40 MPH. Our technicians tell us this condition is commonly caused by a failed automatic transmission torque converter. It is recommend to replace the torque converter and install an updated powertrain control module (PCM) to correct this concern.

A squeak type noise may be noted when raising or lowering the front door glass. Our technicians tell us that in most cases this issue can be corrected by replacing the door glass seal.

The Acura TLX may have issues with the idle air control system, causing:

The idle air bypass system is made up of vacuum lines, an idle air control valve (IACV), the throttle body, and intake manifold, and allows enough air into the engine to idle when the throttle body is closed. The OBD trouble code P0505 refers you to this system to inspect for failures.

The most likely cause is a dirty or failed IACV, but vacuum lines, intake manifold gasket, throttle body gasket, and IACV gasket should be inspected.

In all cases involving the IACV, the throttle body ports should be cleaned prior to installing the IACV onto the throttle body.

 

The car will sometimes not start because of a problem with the ignition switch. Some models may have been recalled by Acura for this issue, please check with your dealer to be sure.

Automatic transmission problems are common and these transmissions have high failure rates.  Acura has voluntarily extended the warranty on many of its automatic transmissions, so be sure to check with an Acura dealership to confirm warranty coverage.

Automatic Transmission May Fail Prematurely

A loud rattle type noise may be noted from the engine after a cold start. This can be caused by a faulty valve timing control actuator. Replacing the failed actuator will commonly correct this noise issue.

Acura issued a recall on a number of 2005 vehicles because the gas tanks were improperly manufactured and could leak in the event of a crash. It is unclear if all the fuel fill issues are related to the recall or not. For more information on this recall please click here»
