Is the 2001 honda passport a decent car?

It hasn't been abused ever, oil changes were kept but but it has 187,000 miles on it.

No. It's not a decent car, because it's a truck (or "SUV" if you prefer). It's actually an Isuzu Rodeo with Honda badges slapped on it; the Passport is nothing special. Isuzu pulled out of the US market back in 2005, but you can still get some parts at Honda dealers.

That's high miles, but if well maintained it could last a bit longer - it's not nearly as good as a real Honda.

I would almost always recommend any Honda vehicle. However this is one I would not recommend anyone buy. Like James M said the 2001 Honda Passport is nothing more than a rebadged Isuzu Rodeo. This is a very unreliable poorly made vehicle with many problems. When it comes to the engine problems on this vehicle are failure of the Intake Manifold Gaskets, the Fuel Level Sensor and the Engine Short Block. Failure of the Intake Manifold Gaskets may cause a rough idle or the Check Engine Light to illuminate. Failure of the Fuel Tank Sending Unit may cause the Fuel Gauge to be inaccurate and may turn on the Check Engine Light. Lack of maintenance can cause the pistons rings to stick resulting in excessive engine oil usage. This engine oil usage can lead to piston rod bearing failure resulting in replacement of the Short Block. The cost to replace the Intake Manifold Gaskets is estimated at $46.00 for the parts and $149.50 for labor. The cost to replace the Fuel Level Sensor is estimated at $359.58 for parts and $162.50 for labor. The cost to replace the Short Block is estimated at $4,280.00 for parts and $1,235.00 for labor. All prices are estimates based on $65.00 per flat rate hour and do not include diagnostic time or any applicable sales tax. And then there are problems with the brake system. An occasional problem on this vehicle is failure of the Electronic Brake Control Module (EBCM) for the Antilock Brake System (ABS). Failure of the EBCM can cause the ABS hydraulic pump to run all the time or the ABS light to illuminate. The cost to replace the EBCM is estimated at $192.35 for parts and $65.00 for labor. All prices are estimates based on $65.00 per flat rate hour and do not include diagnostic time or any applicable sales tax.
