Known Problems

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 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.

The 2004-2014 Acura TSX has brake caliper issues, which are known for causing vibration and grinding noises at all times.

The brake rotor is a disk that sits between two brake pads. The brake pads are squeezed against the disk by what is called a brake caliper. When that caliper gets stuck, the brake pads are permanently pressed against the rotor causing:

  • Vibration in brake pedal
  • Vibration on steering wheel
  • Illumination of the ABS or brake warning light
  • Grinding noise from one corner of the vehicle
  • Vehicle pulls to one side of the road
  • Braking requires more pressure on the brake pedal
  • The repair for a seized brake caliper, the brake pads, brake rotor, and brake caliper must be replaced or vibration will remain after the new caliper is installed. Changing the brake fluid and flushing the brake system according to manufacturer specified intervals can help improve longevity of the brake caliper.

    The 2004-2014 Acura TSX engine oil pressure sensor is known to leak from normal operation.

    More information about the oil pressure sensor here.

    To correct the leak, the sensor must be inspected, properly sealed and installed, or replaced with new.

    The illumination of the entertainment/navigation screen and switches may fail. This is generally caused by a failed circuit board. Acura has extended the warranty on the audio display unit to 7 years or 105,000 miles for the 2004 model year only.

    Some vehicles may develop a soft, low brake pedal. Our technicians tell us this condition may be caused by a faulty vehicle stability assist (VSA) modular control unit. If this is the case replacement of the VSA modular control unit would be required.

    The Check Engine Light may illuminate with a stored code P2422. Our technicians tell us this can be caused by spider webs in the EVAP system charcoal canister vent hose. Acura has made available a spring to install inside the vet hose to correct this issue.

    Engine ping may be noted under moderate to heavy acceleration. Our technicians tell us a revised knock sensor and powertrain control module (PCM) software are available to correct this concern.

    A faulty tire pressure sensor may cause illumination of the low tire warning light even if tire pressure are correct. If this condition occurs the affected sensor(s) should be replaced.

    The fuel door may not open correctly at times. This may be caused by a lack of clearance between the fuel door and the release latch. The common repair is to slightly trim the top of the fuel door lock tap.
