Understanding Your 2018 Dodge Journey AWD System

First things first, let's get a handle on how the AWD system in your 2018 Dodge Journey actually works. This is important because understanding the system's components is key to diagnosing problems. The Journey's AWD system is designed to provide extra grip and stability, especially in slippery conditions like snow or rain. It typically operates in a front-wheel-drive mode to save fuel and then automatically engages the rear wheels when it detects wheel slippage. This is usually managed by a transfer case, which distributes power between the front and rear axles, and an electronic control module (ECM) that monitors wheel speed, throttle position, and steering angle to determine when to engage the AWD. The transfer case, a crucial component, houses gears and clutches that direct power to the rear wheels when needed. This is the heart of the system, and where many problems can originate. The electronic control module (ECM) is the brain, receiving signals from various sensors and deciding when to activate the AWD. Understanding this architecture is crucial. The ECM can sometimes malfunction, leading to a host of problems. So, when the AWD light pops up on your dashboard, you'll have a better idea of where to start looking. Knowing how the system functions can save you both time and money when it comes to troubleshooting. The AWD system on the 2018 Journey is generally reliable, but like any mechanical system, it can encounter issues. The goal here is to help you learn how to identify potential problems.

Key Components and Their Roles

• Transfer Case: This is where the magic happens. The transfer case splits the engine's power between the front and rear axles. It contains gears, chains (sometimes), and clutches that engage the rear wheels when the system detects slippage. This is a critical component, and a failure here can result in no AWD functionality.
• Electronic Control Module (ECM): The ECM is the brain of the operation. It receives signals from various sensors (wheel speed sensors, throttle position sensor, etc.) and determines when to engage the AWD. The ECM can be a source of problems, often due to software glitches or sensor failures.
• Wheel Speed Sensors: These sensors monitor the speed of each wheel. If the ECM detects a difference in wheel speeds, it knows that the vehicle is experiencing slippage and activates the AWD system. A faulty wheel speed sensor can lead to the AWD system not engaging properly or triggering warning lights.
• Rear Differential: This component allows the rear wheels to rotate at different speeds when cornering. It's connected to the transfer case and receives power when the AWD is engaged. Issues here are less common but can contribute to overall AWD performance problems.

Common 2018 Dodge Journey AWD Problems

Alright, let's get down to the nitty-gritty and talk about the most common problems you might encounter with your 2018 Dodge Journey AWD. The problems will be related to the AWD, but there are other problems that can occur as well, so pay attention. From the AWD light staying on to strange noises and performance issues, we'll cover it all. These issues can range from minor annoyances to more serious mechanical failures, so early detection is key. Understanding these problems will help you be proactive about maintenance and repairs, and knowing the warning signs can save you a lot of grief. Let's dig into some of the most common issues. These are common issues, so be sure you pay close attention, and don't hesitate to seek out professional help.

1. AWD System Failure and Engagement Issues

One of the most frequent complaints is related to the AWD system not engaging or disengaging properly. This can manifest in a few different ways. You might notice that the AWD light is constantly illuminated on your dashboard, or that the system doesn't seem to be activating when you expect it to, such as when driving in snowy conditions. This could be due to several factors, including a faulty transfer case, problems with the ECM, or issues with the wheel speed sensors. Often, these issues can lead to reduced traction and handling, especially in less-than-ideal weather conditions. One of the main culprits here is a failing transfer case. Internal components like gears and clutches can wear out over time, leading to the system's failure to engage. Another potential cause is problems with the ECM. The ECM controls the AWD system and can be affected by software glitches, sensor failures, or even wiring issues. A malfunctioning wheel speed sensor can also prevent the system from engaging. If the sensors aren't accurately detecting wheel slippage, the ECM won't activate the AWD. Also, check the fuse box, because a blown fuse will also render the AWD system inactive. When dealing with AWD engagement issues, it's always a good idea to start by checking for any stored diagnostic trouble codes (DTCs) using an OBD-II scanner. These codes can provide valuable clues about the source of the problem.

2. Transfer Case Problems

The transfer case is the heart of the AWD system, and it can be a source of problems in the 2018 Dodge Journey. One common issue is a transfer case leak, which can result in a loss of fluid and damage to internal components. This can lead to the transfer case overheating, and eventually failing. Another potential problem is internal wear and tear. Over time, gears, chains (if equipped), and clutches inside the transfer case can wear out, causing the system to malfunction. You might hear strange noises coming from the transfer case, such as clunking or whining sounds, which could indicate a problem. Regularly checking and maintaining the transfer case is crucial. Regular fluid changes are essential to keep the transfer case lubricated and operating correctly. Using the correct type of fluid and following the manufacturer's recommended service intervals is very important. If you suspect a problem with your transfer case, it's best to have it inspected by a qualified mechanic. Depending on the extent of the damage, repairs might include replacing seals, repairing or replacing internal components, or even replacing the entire transfer case. Ignoring transfer case issues can lead to more extensive and costly repairs down the road. It is better to deal with it now rather than later.

3. Suspension Issues

While not directly related to the AWD system, suspension problems can still affect the overall performance and handling of your 2018 Dodge Journey, and this can indirectly affect the AWD system's effectiveness. The Journey's suspension can be prone to issues, such as worn shocks and struts, or problems with the control arms and ball joints. These problems can lead to reduced ride comfort, poor handling, and increased tire wear. Worn shocks and struts can diminish the vehicle's ability to maintain contact with the road, affecting the AWD system's effectiveness, especially in slippery conditions. Worn control arms and ball joints can affect wheel alignment, leading to uneven tire wear and reduced handling performance. Regular suspension maintenance is important.
