RepairPal Verified 2004 Acura TSX Problem Reports
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.
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 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.
