Known Problems

The engine valves can prematurely fail. The cylinder head will need to be replaced due to wear in the area where the valves seal. Intake or exhaust valve failure may illuminate the Check Engine Light. The car may have poor engine performance and fail emission tests.

A rear engine mount that is broken can cause an engine vibration felt in the vehicle. Replacing the failed mount will repair this problem.

On certain models a leaking side marker light wire harness can cause a water leak inside the vehicle. Resealing the wire harness where it goes through the body into the cabin area should stop the leak.

On certain models with rear disc brakes, a grinding noise can be caused by corrosion between the rear brake caliper bracket and the brake pad retainers. Cleaning and lubricating the caliper bracket and pad retainers should correct this concern.

Certain models can leak oil externally or allow coolant into the combustion chamber due to a faulty head gasket. The head gasket needs to be replaced to correct this problem.

The Honda Accord 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 front axles are prone to failure on the 1990-2002 Honda Accord 4-Cylinder. This will be evident as fast clicking or popping sounds will be audible while driving, most commonly when the steering wheel is turned while the vehicle is in forward motion.

Constant velocity (CV) axles, sometimes called a “half-shaft”, are designed to allow the wheels to be driven by the transmission, even when turning the steering wheel.

They are manufactured of a shaft with a gear at both ends. When one of the gears on the end of the shaft fails, it will make noise as the vehicle is driven.

The axle should be replaced immediately, or damage may occur to the wheel bearing/hub assembly if left unattended.

 

The exhaust recirculation valve (EGR) on the 1990-2007 Honda Accord V6 may fail, causing:

  • Illumination of thecheck 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.

    Damaged engine mounts can lead to vibration and roughness felt in the steering wheel. A rattle in the dash and engine area may also be heard. Replacement of damaged mounts will commonly correct these issues.

    The temperature control knob may break, requiring replacement.

    Poor radio reception can be caused by corrosion in the antenna mast. Replacement of the antenna and other corroded parts will be needed.
    Use of incorrect oil in the rear differential on AWD models will cause a "chattering" sound and vibration on turns. Use only Honda-approved differential oil.

    The Honda Pilot 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 1997-2002 Honda CR-V, both 2WD and AWD versions, commonly leak coolant from the radiator due to normal operation. The leak starts small, but may cause:

  • Coolant puddling under vehicle
  • Engine overheating
  • Unexplained coolant loss (only at first)
  • Vehicle in “limp mode”; loss of power
  • Cylinder head or head gasket failure
  • The coolant leaking can have a severe effect on your vehicle if left in disrepair. If the radiator is diagnosed as the leaky part, it will need to be replaced, or resealed if that is an option.

    Note: coolant is toxic to animals, but tastes sweet. Any coolant spills should be cleaned to protect animals and children.

    A chirping noise coming from the timing belt area can be caused by a misaligned, or tilted idler pulley.
