The 2001 Honda Passport: A mid-size SUV built on truck foundations

The 2001 Honda Passport is a mid-size sport utility vehicle that shares its frame and engine with the Isuzu Rodeo. Honda sold the Passport from 1994 to 2002, and the 2001 model sits near the end of that run. It's a body-on-frame SUV, meaning the metal body bolts onto a separate steel frame underneath — the same construction method used in pickup trucks. This matters because it affects how the vehicle handles, what it can tow, and what maintenance it needs.

The 2001 Passport came with a 3.2-liter V6 engine producing 205 horsepower, paired with either a five-speed manual or four-speed automatic transmission. It offered two-wheel drive or four-wheel drive, and the four-wheel-drive system could be shifted between high and low range while driving on pavement or off-road. The vehicle sat higher off the ground than a car-based SUV and had more ground clearance, which made it capable on rough terrain but also made it less stable in emergency maneuvers on highways.

Key Takeaways

  • The 2001 Passport uses a truck frame and V6 engine, so it requires truck-level maintenance including regular transmission fluid checks and frame rust inspection in salt climates.
  • Four-wheel-drive models need transfer case fluid changes and differential service, which are not routine on passenger cars and add to ownership costs.
  • The 3.2-liter V6 is known for reliability but can develop timing belt issues after 100,000 miles, making that service critical for long-term ownership.
  • Body-on-frame construction means the frame can rust through in northern climates, potentially making the vehicle unsafe even if the engine still runs well.
  • Fuel economy ranges from 16 to 20 miles per gallon depending on drive type and transmission, which is typical for SUVs of that era but worth factoring into running costs.

Engine and transmission maintenance specific to the 2001 model

The 3.2-liter V6 in the 2001 Passport is a durable engine, but it has a timing belt that must be replaced at 105,000 miles. This is not optional. The timing belt synchronizes the crankshaft and camshaft so the valves open and close at exactly the right moment. If it breaks, the pistons can strike the valves, causing catastrophic engine damage that costs $2,000 to $4,000 to repair. Many owners who skip this service end up with an engine that won't run at all.

The transmission fluid should be checked every month and changed every 30,000 to 50,000 miles, depending on driving conditions. Automatic transmissions in 2001 Passports can develop shift delays or harsh shifts if the fluid gets old and loses its ability to protect the internal parts. Manual transmissions are simpler but still need regular fluid checks because leaks are common at the seals.

If you own a four-wheel-drive model, the transfer case — the component that splits power between the front and rear axles — needs its own fluid service. Transfer case fluid should be changed every 30,000 to 50,000 miles. Neglecting this leads to grinding noises when shifting between two-wheel and four-wheel drive, and eventually the transfer case can lock up or fail to engage.

Cooling system and overheating risks

The 2001 Passport's cooling system uses a radiator, water pump, thermostat, and hoses to keep the V6 engine at the right temperature. The radiator can develop leaks or internal corrosion after 20 years, especially if the original coolant was never flushed. When the radiator fails, the engine overheats within minutes, and continued driving can warp the cylinder head or crack the engine block.

The water pump typically lasts 80,000 to 120,000 miles before the internal seal fails and coolant leaks out. A failing water pump is often caught early because you'll see a puddle under the vehicle or smell sweet coolant. Replacing it costs $300 to $600 in labor and parts, but waiting until it fails completely can leave you stranded.

Check the coolant level when the engine is cold, at least once a month. The coolant should be bright green or pink depending on the type Honda used at the factory. If it looks brown or rusty, the system needs flushing. A flush involves running a cleaning solution through the radiator and hoses to remove corrosion, then refilling with fresh coolant.

Suspension and steering components that wear faster on truck frames

Because the 2001 Passport is built on a truck frame, it uses a solid front axle and leaf springs in the rear. This setup is rugged but creates more wear on suspension parts than the independent suspension found in car-based SUVs. The ball joints, tie rods, and control arm bushings wear out faster, especially if you drive on rough roads or tow a trailer.

Ball joints connect the steering knuckle to the control arms and allow the wheels to turn and move up and down. When a ball joint wears out, you'll hear a clunking sound when turning or going over bumps, and the steering wheel may feel loose. A worn ball joint is a safety issue because the wheel can separate from the vehicle if it fails completely. Replacement costs $200 to $400 per side.

The steering linkage — the rods and joints that connect the steering wheel to the front wheels — should be inspected every 30,000 miles. Look for torn rubber boots around the tie rod ends, which allow dirt and water inside and speed up wear. If you notice the steering wheel is hard to turn or the vehicle pulls to one side, have the steering system checked before the problem gets worse.

Brake system maintenance and pad wear patterns

The 2001 Passport has disc brakes in front and either disc or drum brakes in the rear, depending on the model year and trim level. Brake pads typically last 25,000 to 70,000 miles depending on your driving style. Hard braking, towing, and mountain driving wear pads faster. When pads get thin, metal-to-metal contact happens and you'll hear a high-pitched squealing or grinding sound.

Brake fluid should be flushed every two years or 30,000 miles because it absorbs moisture from the air. Moisture in brake fluid lowers its boiling point, which can cause brake fade — a spongy pedal feel or loss of braking power — especially when braking hard or towing downhill. A brake fluid flush costs $100 to $200 and is one of the cheapest preventive services you can do.

If the vehicle has drum brakes in the rear, those components are harder to inspect yourself but should be checked every 50,000 miles. Drum brakes can develop weak spots where the friction material separates from the backing plate, causing the brake to fail suddenly. Have a mechanic inspect the drums and wheel cylinders during routine service.

Frame rust and structural integrity in northern climates

The 2001 Passport is now over 20 years old, and in states that use road salt during winter, the frame can rust through. A body-on-frame vehicle depends on the frame for structural strength. If rust eats through the frame, the vehicle becomes unsafe because the body can shift or flex, and the suspension and steering components may not stay aligned.

Inspect the frame by getting under the vehicle and looking for orange or brown rust, flaking paint, or holes. Pay special attention to the areas where the frame meets the body, where water collects and rust starts. If you see surface rust, you can slow it down by washing the undercarriage regularly and explore a rust inhibitor spray. If you see holes or deep pitting, the frame may be compromised and the vehicle may not be safe to drive.

In dry climates, frame rust is less of a concern, but you should still check the undercarriage every year. A vehicle with a solid frame and good undercarriage condition will last much longer and be safer to drive than one where rust has weakened the structure.

Fuel system and tank corrosion

The fuel tank in a 2001 Passport is steel and can rust from the inside out, especially if the vehicle sits for long periods or if water gets into the tank. Rust particles can clog the fuel filter and injectors, causing rough idle, hesitation during acceleration, or stalling. If the tank develops a leak, fuel will drip from under the vehicle and create a fire hazard.

The fuel pump sits inside the tank and can fail if it draws in rust particles or if the electrical connector corrodes. A failing fuel pump will make a whining sound from the rear of the vehicle, or the engine may not start at all. Fuel pump replacement requires dropping the tank and costs $400 to $800 in labor and parts.

If you notice a strong fuel smell or see fuel dripping, do not drive the vehicle. Have it towed to a mechanic for inspection. A fuel leak is a serious safety issue and needs when ready attention.

Frequently Asked Questions

What's the difference between the 2001 Passport and the Isuzu Rodeo?

They share the same frame, engine, and transmission, but Honda added different trim levels, interior styling, and badging. Mechanically, maintenance and repair procedures are nearly identical. Parts availability and pricing may differ slightly between Honda and Isuzu dealers, but most independent shops can service both vehicles the same way.

How much can the 2001 Passport tow?

The towing capacity is 3,500 pounds for two-wheel-drive models and 5,000 pounds for four-wheel-drive models, depending on the transmission and final drive ratio. Check your owner's manual or the door jamb sticker for your specific vehicle's capacity. Towing puts extra stress on the transmission, cooling system, and brakes, so regular maintenance becomes even more critical if you tow regularly.

Is the 2001 Passport still worth buying today?

It depends on condition and price. A well-maintained example with full service records, no frame rust, and recent timing belt replacement can be reliable transportation. However, fuel economy is poor by modern standards, and parts are becoming harder to find as the vehicle ages. Budget for potential major repairs like transmission service, suspension work, and frame inspection before buying.

What should I look for when inspecting a used 2001 Passport?

Check the undercarriage for frame rust, especially around the rear axle and where the body bolts to the frame. Ask for proof of timing belt replacement — if it hasn't been done, budget $1,000 to $1,500 for that service. Listen for clunking or grinding sounds during a test drive, which indicate suspension or transmission wear. Have a pre-purchase inspection done by a mechanic who knows truck-based SUVs.

What's the most common repair on high-mileage 2001 Passports?

Suspension work is the most frequent repair on vehicles over 100,000 miles. Ball joints, control arm bushings, and tie rod ends wear out and need replacement. Transmission fluid leaks are also common, especially on automatic models. If the vehicle has over 120,000 miles and the timing belt hasn't been replaced, that's the first major service to budget for.
