Honda Odyssey Problems
RepairPal has identified the most common problems with the Honda Odyssey based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The Honda Odyssey 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 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.
There have been some issues reported with the electric sliding doors. Our technicians remind us that proper diagnoses will be necessary to determine the cause of various faults which may occur.
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 Honda Odyssey may develop issues with the automatic transmission.
Rough shifting may occur, and the “D4” light and check engine may begin to blink. The check engine light will also illuminate, and OBD trouble codes P0700, P0730, P0740, P0780, P1768 and/or P1768 will be stored in the computer.
If the transmission shifts roughly, the failure is very likely mechanical failure of the transmission. If the transmission performs normally, a faulty sensor, or dirty transmission fluid may be the case.
In most cases, it is necessary to use professional diagnostic equipment to provide a diagnosis, and complete the repair.
The longevity of the transmission is dependent on strict adherence to the manufacturer's recommendation for ATF replacement intervals and procedure.
A rear engine mount that is broken can cause an engine vibration felt in the vehicle. Replacing the failed mount will repair this problem.
Manual sliding doors will stick or not open easily due to the door seal sealing too well. Sometimes this can cause the door handle to break when trying to open the door. Replacing the door seal with an updated seal from Honda will repair this issue.
There have been reports of various transmission problems with this model.
Honda issued a recall on some 2005 Odyssey models due to a defective fuel pump relay. If the fuel pump relay fails, the car will stall or fail to start. For more information on this recall please click here»
The clock light has a tendency to burn out.
The Honda Odyssey has a known issue with engine oil leaking from the ignition distributor shaft seal.
Leakage from the shaft seal coats the electrical components of the distributor with engine oil causing:
Cleaning the distributor cap and rotor can help or resolve driveability issues temporarily, but the mentioned issues will return shortly.
Once this issue is diagnosed, the ignition distributor shaft seal must be replaced, and the distributor shaft bearing must be inspected.
Third row seat latch cables can come loose from the handle and can prevent the seat from unlatching. Reinstalling the cables and retaining them with clips should correct this issue.
The front axles are prone to failure on the 1995-1998 Honda Odyssey. 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 1995-1998 Honda Odyssey engine oil pressure sensor is known to leak from normal operation.

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