Known Problems

The fuel pump may fail causing the engine to stall and not restart.

The 1990-2005 Honda Civic commonly have issues with radiator leaks due to normal operation. The leak usually starts small with the engine running slightly warmer than normal, but may/will eventually 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.

    If the engine is difficult to start or cranks but does not start, it can be caused by a leak in the return side of the fuel system. This type of leak can allow air to enter the injection pump resulting in starting issues. A rubber hose on the back of the injection pump, connecting the pump to the steel hard line, that can be the source of this type of leak.

    The front brake rotors can warp and cause a vibration when braking. The rotors will need to be machined or in cases where they are worn to thin, replaced to correct this issue.

    The thermostat may fail to close completely, causing the Check Engine Light to illuminate. This problem will prevent the engine from reaching normal operating temperature; a new thermostat should be installed.

    The 4WD transfer case encoder motor position sensor or the selector switch may fail causing the service 4WD message to be displayed. Fault code(s) stored in the transfer case control module will be of assistance in determining the exact fault causing the message to be displayed.

    The Volkswagen Tiguan uses the TSI direct injection engine. This engine is subject to carbon buildup in the intake system which can cause power loss, OBD codes and a check engine light, and a rough idle. In normal engines, the engine is cleaned by the gasoline flowing through the injectors and into the intake system, however, since the Tiguan uses direct injection, gasoline does not flow through common carbon buildup areas. 

    Possible trouble codes include: P0300P0301P0302P0303P0304.

    The solution is to remove the intake manifold and professionally clean the intake manifold, intake ports on the cylinder head, and the intake valves. This may need to be done in as few as 20,000 miles. 

    A knocking sound my be heard from the engine at times with the air conditioning on. The cause could be the AC compressor itself, if that is the case there is an updated AC compressor to correct this issue.

    The catalytic converter closest to the cylinder head can fail causing illumination of the Check Engine Light. Prompt repair of this problem is recommended because the catalyst material can be sucked into the engine and cause internal damage.

    It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

    The engine may develop and oil leak due to a porous engine block casting. The repair procedure is dependent on where the leak is located. Honda has released a service bulletin covering model years 1998-2003. Honda may offer assistance with repairs, determined on a case by case basis.

    Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.

    Reprogramming the transmission control module with the latest Kia transmission software may fix abnormalities in the automatic transmission and erroneous transmission-related Check Engine Light illumination. Software updates are commonly most effective on newer vehicles. Higher mileage vehicles may exhibit a similar symptom caused by a component failure. However, whenever major transmission repairs are performed the transmission software should be checked and updated as necessary.

    Some models may have a problem with stalling under light acceleration. Updated software for the powertrain control module (PCM) is available which may help with this concern.

    There are T-shaped vacuum connectors under the intake manifold that can break and cause a rough idle.

    The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

    On higher mileage vehicles, one or more EGR orifice in the intake manifold may plug with sludge. This can cause the engine to misfire when first accelerating because too much exhaust gas is directed into the cylinders where the orifice is not plugged. Cleaning the clogged passages should correct this concern.

    Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

    The evaporative emission (EVAP) system may illuminate the vehicle's Check Engine Light due to intermittent failure of the charcoal canister purge control solenoid valve or canister failure. Upon failure of the charcoal canister, debris may circulate around the EVAP system causing other emission control problems.

    A sticking intake manifold runner solenoid can cause the Check Engine light (MIL) to illuminate. Replacing the solenoid will repair the issue.

    Reprogramming the transmission control module with the latest Kia transmission software may fix abnormalities in the automatic transmission and erroneous transmission-related Check Engine Light illumination. Software updates are commonly most effective on newer vehicles. Higher mileage vehicles may exhibit a similar symptom caused by a component failure. However, whenever major transmission repairs are performed the transmission software should be checked and updated as necessary.

    The engine may fail to start due to an electrically shorted sensor. Some of the sensors may internally short and not blow any fuses. A technician may find no spark and no operation of the fuel injectors in the diagnosis. One way a technician may isolate the defective sensor is by disconnecting sensors one by one to see if the engine starts.

    The Check Engine Light may illuminate with a fault code P1121 stored. It is commonly caused by a failed three way coolant control valve. Valve replacement is recommended if this occurs.

    The V8 models can experience exhaust manifold failures. A leaking exhaust manifold will sound like an exhaust leak or an audible ticking noise from the engine compartment and will be especially pronounced when the engine is still cold.
