Fixing Your Toyota RAV4’s AWD System Malfunction
Any time you see a warning message on your RAV4 it can be concerning, especially when it impacts a major system like all-wheel-drive (AWD).
Understanding the cause and fixes for this issue will help ease your concerns. Below, we’ll discuss the common causes, safety concerns, and how to fix your AWD system malfunction.
Interpreting the Error
It’s pretty obvious when you have an AWD system issue on a Toyota. You’ll see a big warning message pop up on your multi-information display to inform you of the error. This is the display on your dashboard between the tachometer and speedometer.
This warning message will read:
AWD System Malfunction
2WD Mode Engaged
Visit Your Dealer
This message is the most common indicator that there is something wrong with your all-wheel drive system. Your car has built-in electronics to detect when it is not working properly, then it produces this message to warn you about it.
When you see this warning, it also means that the AWD system is disabled electronically. This is done to prevent further damage to the system. Since AWD is disabled in this case, that means you’ll be operating in two-wheel drive (2WD). This means only your front two wheels are getting power to drive your car forward.
As a driver, you didn’t necessarily do anything specific to trigger this message. However, you’ll need to take action to resolve the error and ensure you can use all-wheel drive in the future.
Potential Causes
Many drivers see this error message pop up randomly. This message can occur after an event that has nothing to do with AWD.
Here are a couple of commonly reported causes for this error outside of an actual AWD system issue:
- The battery has died, and the car has been jump-started
- The gas cap is loose
- The “check engine” light is on
If you have recently had either one of these events occur, then you can feel at ease that this is likely the cause. There may not actually be anything wrong with your AWD system itself.
If neither of these causes apply, we recommend taking your vehicle to a local mechanic to ensure you can get any issue diagnosed promptly.
How to Resolve
Some Toyota owners report that a loose gas cap can cause check engine lights and warnings to appear, but this doesn’t always resolve an AWD malfunction warning.
More likely than not, you’ll need to visit a mechanic or Toyota dealer to understand the cause of the malfunction. Unfortunately, an AWD System Malfunction isn’t typically something you can fix on your own.
To get started on diagnosing the issue, I have some recommendations depending on what warning lights you see on your dashboard.
You’ll want to look for your “check engine” light. It looks like this:
If your “check engine” light is on: Get your engine error codes checked by your local mechanic, auto parts store, or Toyota dealer. The AWD system is automatically disabled whenever the check engine light turns on, so there may not be anything wrong with your AWD system. You can also check the error codes yourself with an ODB2 scanner.
If your “check engine” light is not on: This may be more complicated to solve. Take your vehicle to your Toyota dealership so they can diagnose the issue.
Repair Cost
If you’ve determined that your AWD malfunction is a result of damage to the vehicle, you’ll need to get it repaired.
It’s tough to estimate the overall cost of repairing an AWD system because there are many different parts involved. It depends on which part is affected.
For example, the average cost to repair a RAV4 driveshaft is $794 ($699 for parts and $95 for labor). However, replacing an entire transfer case could cost anywhere from $2,000 to $7,700 depending on various factors such as location, model year, etc.
The best option is to visit a local mechanic or Toyota dealership for an accurate quote for your vehicle and situation. They’ll be able to assess any damage and give an accurate repair cost.

Is It Safe to Drive?
Whenever a malfunction light or warning comes on, it’s natural to be concerned about the safety of your vehicle. Can you continue to drive? If so, for how long? Would it be best to stop at the next mechanic you see?
When it comes to an AWD system malfunction, it is normally safe to drive with the warning showing. However, you must use increased caution while operating your vehicle.
The AWD warning indicates that the system is malfunctioning, and thus, your car disables it entirely as a precaution. Therefore, your front wheels are the only wheels powering and driving the vehicle. This is more dangerous when you’re in slick conditions like rain or snow. Use caution as your vehicle will handle differently than expected.
Although it remains safe to drive your vehicle while AWD is disabled, get the problem diagnosed and fixed as soon as possible. You’re still operating a vehicle in a compromised state.
Use the following information to determine when it’s safest to drive a vehicle in 2WD (since your AWD is disabled).
2WD is safe on:
- City streets
- Dry pavement
- Clear roads
2WD is potentially unsafe* on:
- Snow-covered roads
- Ice-covered roads
- Gravel
*It’s true that there are many 2WD vehicles on the road that drive in these “potentially unsafe” conditions. However, it’s most important to know that your vehicle will behave much differently in these scenarios if your AWD system is malfunctioning.
Here’s an example video of how 2WD and AWD perform in snow. The video starts with the vehicle in 2WD, then switches to AWD.
Recap
AWD is a key feature of the RAV4. However, there are some instances in which you may see the “System Malfunction” warning appear.
If this is the case, don’t panic! Yes, something is wrong and needs to be fixed. But for now, it simply means you’re operating in two-wheel drive (2WD), which is standard for many vehicles.
Stick to city streets, dry pavement, and clear roads for best results. When you can, visit a mechanic or Toyota dealership to get answers about what’s causing the malfunction. If you use increased caution, you should still have a perfectly safe driving experience.Â
