Honda Passport Problem Reports
Most Reported Honda Passport Problem Reports
Varnish build up in the engine can cause one or more hydraulic lash adjusters to stick and cause a ticking noise in the engine. The noisy hydraulic lifter will need to be located and cleaned to stop the noise.
Certain models may have a vibration issue at highway speeds that could be due to uneven tire pressures, tire rim out of specs, wheels out of balance, AC compressor bracket bolts not torqued correctly, misalignment of the steering shaft coupler, improper ride height, or wheel alignment out of adjustment. A qualified technician is needed to sort out these problems and correct them.
A worn vehicle speed sensor driven gear can cause the speedometer not to work. Replacing the worn out speed sensor should correct this concern.
A broken hatch button can cause the rear hatch not to open when you push the release button. Replacing the button should repair this issue.
The fuel level sensor may fail resulting in erratic fuel gauge operation and illumination of the Check Engine Light. Replacement of the fuel sender assembly is recommended to correct this concern. A powertrain control module (PCM) software update may be necessary for the updated fuel level sensor to read correctly.
Dry suspension components can cause a spring-type pop when it moves. Lubricating the suspension will stop the noise.
On the V-6 engine, oil in the spark plug tubes can cause a misfire. Resealing the tubes as part of replacement of the valve cover gasket and replacing the spark plug wires will commonly repair this issue. On newer models the misfire can result in illumination of the Check Engine Light.
On some models the powertrain control module (PCM) software delays idle speed changes during cold starts causing stalling problems. A software update from Honda will repair this particular issue.
Fuel injector "leakdown" can cause a long crank time after the engine is warmed up. The fuel injectors need to be replaced to address this problem.
On some models, the right motor mount cover can hit the chassis and cause a vibration at idle. Replacing the motor mount will repair this issue.
