When you run into issues with your Acura SUV (MDX/RDX) door not functioning properly, it can be frustrating. You may encounter issues with the locks, or the doors themselves having problems opening or closing.
If your Acura SUV (MDX/RDX) doors are not working there are several issues that you could face. When it comes to troubleshooting them, it depends on what you are experiencing with your doors. It could be a component within the door itself, or you could face issues with the electronics or mechanics of your Acura SUV (MDX/RDX).
A frequent cause for door lock issues in Acura SUVs, including MDX and RDX models, is a faulty door lock actuator. The actuator controls the locking mechanism and can wear out over time. To fix this, the faulty actuator needs to be replaced. This involves removing the door panel to access the actuator, disconnecting it, and installing a new one. While it’s a more involved repair, it’s often the key to resolving door lock problems.
Another reason could be a problem with the vehicle’s electrical system, particularly a blown fuse. If the fuse that controls the door locks is blown, the locks won’t function correctly. Locate the fuse box, often found under the dashboard or in the engine compartment, and check the fuse related to the door locks. Replace it if it’s blown. This is a simple and quick fix that can restore the functionality of the door locks.
The good news is that many of these problems are easy, and cheaper, to fix yourself, rather than bringing your car into the shop. Here are a few of the common problems that you might encounter with your Acura SUV (MDX/RDX) doors, and how to fix them.
Acura SUV (MDX/RDX) Door Won’t Open (Cause and Fix)
One issue that you may encounter with your Acura SUV (MDX/RDX) is the door not opening. This is a problem that typically affects the driver’s side door. The frustrating part, besides not being able to open your door, is usually when this occurs, you are still able to lock and unlock your car door, but to no avail.
If your Acura SUV (MDX/RDX) door won’t open, you need to remove your door panel. To open your car door, there is a series of moving parts that make this possible. There is a rod that is connected to the latch that opens your door. The rod is supported by a plastic clip. If this clip breaks, the rod won’t have enough support or tension to flip your latch.
Because opening and closing your doors is something that you do so often, this plastic piece can wear down. If the piece is broken, you will need to replace it for your door to be able to open again.
Acura SUV (MDX/RDX) Back Door Won’t Open (Cause and Fix)
If your Acura SUV (MDX/RDX) trunk or back door won’t open, you should receive a warning on your screen. It will alert you to ‘Check the Power Tailgate’. If this error message comes up, you will be unable to open your back door, even if it is unlocked.

Before replacing the wires, you can check to make sure that they are attached properly. It’s also a good idea to clean out your terminals and sockets to remove any dust or debris that could cause a signal loss. Using compressed air, hold it at least ten inches away and blow out anything that may have become lodged in there over time.
Acura SUV (MDX/RDX) Door Won’t Unlock (Cause and Fix)
Typically, when you run into issues with your door not unlocking on your Acura SUV (MDX/RDX), the most common issue your door will face is your driver’s side door.

If you press it a second time, sometimes the rest of your doors will unlock, but your driver’s side door will still remain locked.
If your Acura SUV (MDX/RDX) door won’t unlock, the most common issue is that your driver’s side door lock actuator is facing mechanical issues.

To determine if the issue is with your lock actuator, you will need to remove the driver’s side door panel to get to the mechanics behind it. Your lock actuator will be connected by two cables. Remove the cables and test the terminals for power. If your terminals have power, then your actuator may need to be replaced.
If there is no power going to your lock actuator, your problem is most likely electrical. You should check your fuse box to see if there are any blown fuses. You should also check to see if there is any damage to the cables themselves. Even if there is power available, a damaged cable can result in a lost connection.
