5 Recurrent All-Wheel Drive System Problems in Honda Pilot

Here are some of the AWD system issues Honda Pilots could face and their potential solutions:

1. Dash Displays AWD Warning Light

The All-Wheel Drive (AWD) warning light on your Honda Pilot vehicle indicates issues with the AWD system.

These include:

Clutch assembly problem
Worn-out components
Transfer case problem
Shaft seal leaks
Loose wires, etc.

Now, to clear the warning light, you’ll need to find out its cause. But, this diagnosis can be tricky. Your best bet is to visit a mechanic.

Note: You can continue driving with the warning light, but timely repair is necessary. The AWD alert essentially deactivates your car’s AWD system, shifting your Honda Pilot into front-wheel drive mode.

2. Honda Pilot Shows Emissions System Error along with AWD Light

If you’re experiencing emissions system errors and an activated AWD light in your Honda Pilot, it’s recommended to visit a service center ASAP.

Why?
The emissions system in modern vehicles is complex and tightly integrated with various components. When an error occurs, it may affect the overall performance of the vehicle, including the AWD system.

Moreover, diagnosing emissions system errors often requires specialized tools and diagnostic equipment.

Here’s what your mechanic will do:

Check the sensors and actuators: They’ll check your vehicle for a faulty O2 sensor or actuator and install new ones. Once the issue is resolved, they’ll use an OBD-II scanner to reset the Honda Pilot emission check system alert.

Examine the wiring harness: The Honda Pilot utilizes eco-friendly soy-based insulation in its wiring, making it prone to damage by rodents. They’ll inspect the wiring for any signs of damage, wear, or fraying.

Check for VCM problems: They’ll dismantle the intake manifold to access the rear cylinder’s VCM (Variable Cylinder Management) unit. They’ll visually inspect, listen for unusual sounds, and monitor performance.

Inspect for fuel injector or HPFP failure: The Honda Motor Company issued service bulletins from 2016-18, addressing issues with fuel injectors or High-Pressure Fuel Pump (HPFP) on third-generation Honda Pilot models. If your fuel injectors are faulty, you can visit a reliable service center to get them replaced.

3. Honda Pilot Displays “AWD Warning — Cannot Transmit Power to the Rear Wheels” Message

Honda’s advanced VTM 4 system, called “intelligent variable torque management,” controls the torque distribution to your car’s rear wheels. This system is designed to enhance your vehicle’s traction and stability, especially while driving in challenging or off-road conditions.

But, if you haven’t gone off-road or had any collision, you may get this warning due to an electrical glitch — a faulty speed sensor or a circuit problem. Further diagnostics would be required to determine the cause.

The good news?
Driving with this warning doesn’t pose an immediate threat to your vehicle.

The Honda Pilot typically operates in the front-wheel drive (FWD) mode, with the rear wheels engaging only in adverse weather conditions when additional traction is required. So, you can drive with only the front wheels engaged until you address the issue. That said, you should be cautious while driving on snowy or slippery roads, as rear wheels will lack traction.

4. Transfer Case Is Leaking

The transfer case uses a fluid (a specific type of automatic transmission fluid) for proper functioning and lubrication.

The output shaft seals prevent this transmission fluid from leaking between the case, rear axle, and rear differential. If these seals wear out or break, lubrication can diminish, causing the transfer case to overheat.

The mechanic will inspect the transfer case, replace the old fluid, and test drive the vehicle to find the leak. If repairable, they’ll disassemble and reseal the case, whereas irreparable damage may require a complete replacement.

5. Check Engine Light On along with VTM 4 Light (Displays P0171/P0174 Code)

These trouble codes indicate your ECU (Engine Control Unit) has detected a lean fuel mixture in your vehicle, activating the check engine light.

These codes can be triggered by:

However, you’ll need a mechanic to identify the exact cause for the VTM 4 system and the check engine light warning coming on.

Now that we’ve discussed common issues and solutions for the Honda Pilot, let’s check out the repair costs to fix them.

How Much Does Honda AWD System Diagnosis and Repair Cost?

Diagnosing the AWD system on a Honda vehicle generally ranges between $100 to $200. You may need to pay extra based on the replacement required.

Here are the estimated costs of some AWD replacements (excluding labor):

Vacuum hose replacement: $12 to $202
Wiring harness replacement: $1300 to $1700
Transfer case replacement: $2000 to $8000

Honda is renowned for reliability and versatility. However, some Honda Pilot users have reported car performance issues from specific model years.
Let’s explore these in detail.

Which Honda Pilot Years Should I Avoid and Why?

While new Honda vehicles ensure a smooth driving experience, the older models may lead to a bumpy ride.

If you’re planning to get a pre-owned Honda Pilot, you should avoid model years: 2003, 2005, 2009, 2011, 2013, and 2016.

Why?
Here are a few reasons:

Transmission problem: Transmission problem is common in the 2003 model and can make your car hard to control, resulting in accidents.

Fuel injector failure: This problem occurred in the 2016 model after 60k miles, resulting in poor fuel economy and costly repairs.

Electrical wiring issues: It’s a common problem in the 2020 model and can affect your car’s navigation system, instrument panel, etc.
