2005 Acura RL Common Problems, Issues, Recalls, and Reliability

• 2005 Acura RL Check Engine Light for Running Rough and Difficulty Starting

  The exhaust recirculation valve ( EGR ) on the 1996-2012 Acura RL may fail, causing:

  • Illumination of the check engine light
  • OBD trouble codes P0401 and P1491
  • Rough idle
  • Reduced fuel economy
  • Engine vibrations
  • Hesitation or stalling
  • Long cranking before engine starts
  • Failure of state or federal smog tests

  The EGR valve has open and closed positions, and opens or closes on command from the computer.

  Exhaust gases constantly pass through the valve when it is open, leaving carbon deposits on the valve. These carbon deposits may lead the the valve sticking in the open or closed position.

  To correct this issue, sometimes it is sufficient to clean the valve, but replacement is recommended in all cases.

• 2005 Acura RL Engine Idle Speed is Erratic or Engine Stalls

  The 2005-2012 Acura RL may have issues with the idle air control system, causing:

  • Erratic/bouncing idle
  • Poor fuel mileage
  • Illumination of the check engine light
  • OBD trouble code P0505
  • Engine stalling is possible

  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.

• 2005 Acura RL Check Engine Light and Engine Takes too Long to Start

  The 2005-2012 Acura RL commonly has problems with the EVAP canister vent solenoid . It stops responding to commands to open and close, and the following occurs:

  • Illumination of the check engine light
  • OBD trouble code P1457 is stored
  • Engine takes longer than usual to start
  • Fuel mileage decreases noticeably

  The valve is located on the charcoal canister , and is meant to open and close upon command. It fails due to corrosion breaking one of two internal seals, which allows air to escape the system, signaling the OBD trouble code P1457.

  Correcting the problem can be done by replacing the vent valve, or, in some cases, cleaning and resealing the vent valve has been successful. You can get an estimate for this repair here .

  A worn, missing, or loose gas cap can cause the same issues.

• 2005 Acura RL Sensor Problems May Cause SRS Light To Turn On

  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.

• 2005 Acura RL Reprogram computer to fix shifting problem in automatic transmission

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

• 2005 Acura RL Engine Stalls While Driving and WIll not Start

  The 1996-2006 Acura RL may have issues with the fuel pump and fuel injection relays .

  These relays send power to the fuel pump and fuel injectors when the key is turned to the “ON” position. So, when they fail, there is no electrical current to the necessary fuel system components to send fuel into the engine, causing engine stalling or failure to start.

  In this situation, there are many other possibilities, so testing components is vital for time and money savings.

  If the relays test bad, they must be replaced with relays specific for that circuit.

  To help prolong the life of your under-hood electrical components, ensure the lid for the fuse block is closed, and any factory sealing material is correctly installed.

• 2005 Acura RL Acura extended automatic transmission warranty

  Acura extended the warranty due to numerous issues with the automatic transmission . Problems with the automatic transmission may make the car undrivable and can result in costly repairs.

• 2005 Acura RL Engine Clicks but Will Not Start

  The starter motor used on the 1996-2006 Acura RL frequently fails on vehicles around 125,000 miles.

  It may help prolong the life of the starter to service the starter to ensure the connections are clean and tight at the 100,000 mile mark.
