Even if the Tesla Model Xs Falcon Wing doors have a bit of a questionable reputation for reliability, its hard to argue that the dual-hinged contraptions arent badass.

Theyre cool not just because they look sexy and can actually make ingress and egress easier, but mostly because of the nerdy engineering that went in their design. A bit of over-engineering never hurt anyone, right?

Heres a video from YouTuber, Tesla Motors Club member and Model 3 Owners club member Trev Page showing just how the Xs doors work:

Trev Page says there are two hinges on the Falcon Wing doors, one at the door/body junction, and one farther outboard. Right where the door meets the body, there are two torsion springs, which constantly apply a force to help rotate the door upward to open it.

In addition, at that same hinge are two electric actuators that not only help push the door open a bit so the torsion springs can work their magic and open the door, but they also act to oppose the torsion springs and close the doors.

At the hinge farther outboard are two pairs of electrical liftgate actuators, not unlike the ones youd seen in modern cars with electric liftgates. Theyre arranged in a way that allows them to push and pull the outer part of the door to tuck it in or open it up.

When a passenger wants to open a door, the electric actuator at the inner hinge pushes the door open a bit, the torsion springs start to move the door upward, the second hinge tucks the outer door in until the inner hinges torsions springs have moved the door all the way up, at which point the second hinges two pairs of liftgate actuators open up the outer door.

So yeah, the doors are fascinating, even if Tesla itself thinks they may be a bit too ambitious.

6 Most Common Problems With Tesla Model X (Explained)

The Model X was Teslas first SUV when it was released in 2017.

Its extremely quick yet very practical and family-friendly.

As new EV rivals enter the market, its still able to stand out with its cutting-edge tech and fancy falcon-wing doors.

In this article well take a detailed look at the most common problems and issues of the Tesla Model X.

1. Suspension Issues

According to Car Problem Zoo, a website that collects customer complaints, suspension failure is the most commonly reported issue for the Model X.

Many Model X owners have complained about constant creaking or clunking noises coming from the front suspension.

A more concerning issue is when the suspension control arms fracture and shear off the ball joints that theyre connected to.

Here is what one owner had to say about their experience:

Driving the vehicle in a parking lot and at low speed turning the wheel, heard a loud pop and the front drivers side wheel started hitting the wheel well. No warning signs or lights came on. After looking under the car a control arm snapped. I am very surprised this could happen at normal use at low speeds.

Control arm failures are a common issue with the Model S which the X shares many parts with. It usually affects Model Xs made from 2015 to 2017 which is before Tesla updated some of the suspension components.

Another common point of failure is the Model Xs air suspension system.

Issues with the air suspension can include:

• Uneven ride height
• Sloppy handling
• Getting stuck in the lowest position
• Complete failure of the air spring

Solution

The noises from the front suspension are usually caused by faulty or worn-out control arms or a damaged air spring.

The cost of the parts depends on the severity of the issue. Individual suspension components should only cost a couple hundred dollars. But it can add up quickly if you need to replace a lot of parts.

2. Vibration or Shudder During Acceleration

Vibration or shuddering from the front of the vehicle is a pretty well-known problem with the Model X.

The vibration usually only appears when the ride height is set higher, but as the problem gets worse, it can be felt even in the Standard or Low suspension setting.

Although Tesla has issued several Technical Service Bulletins (TSBs) to address this issue, weve seen it being reported on early builds from 2015 all the way up to the 2021 cars.

Here is what one owner had to say:

I had my car for almost 12 months and have driven 11,000 miles. In the past one month, I started experiencing a violent shudder/vibration during initial acceleration between 30 to 40mph.

Solution

The shuddering is usually caused by a defective half shaft, which connects the drivetrain to the wheels.

Some people have already had multiple half shaft replacements because the issue keeps coming back.

Another possible culprit is a poorly designed clevis mount which is the subject of a couple of service bulletins.

Theres no conclusive fix as of yet since people with newer vehicles are still reporting the issue.

3. MCU (Media Control Unit) Failure

All Model Xs made before April 2018 use the first generation Media Control Unit or MCU1 which is the computer that runs the infotainment system and the center touchscreen.

These first gen units are prone to failure because of the small 8GB eMMC flash memory that they use.

Over time, and after numerous reads and writes, the memory chip simply stops working and causes all kinds of software errors such as:

• Dash and touchscreen wont turn on
• Frequent reboots
• Slow and unresponsive user interface
• Bluetooth connection issues
• Failed software updates

Here is what one owner had to say about their issue:

The continued Tesla MCU problem. Got bad with system crashing and screens going blank, then finally got the Tesla eMMC memory fix and all was good the last year or so. Then in the last several weeks, it occurred 4 times and I made a service appointment. Tech cleared the drive and said all would be good. Two days later it occurred again. MCU crashed again.

Solution

When the MCUs starts acting up, it has to be completely replaced since the memory chip is soldered onto the board.

You can replace it with another MCU1 computer, but the issue will happen again since its still using the same type of memory.

Upgrading to the MCU2 computer will be more expensive but is a more permanent fix. Its also going to be faster and will have more software features compared to the older unit.

4. Falcon Wing Door Problems

Although the Model Xs Falcon Wing Doors (FWD) are really cool and unique, theyre also significantly more complicated compared to a regular car door.

Here are some of the common issues that people have reported with the Model Xs FWD:

• Poor alignment
• Squeaks and creaks when opening and closing
• Not fully opening
• Opening or closing by itself
• Water leaks
• Wind noise
• Paint peeling off door jambs

More FWD issues occur with the early model years, but due to the numerous parts and systems involved just to make them work, even newer cars will eventually encounter problems.

Model Xs from 2017 onwards did get new FWD seals which should lessen leaks and wind noise.

Solution

The Model X Falcon Wing Doors use lots of different parts and components like motors, sensors, springs, hinges and seals which can fail due to wear and tear.

If you encounter issues with your FWDs, its best to take it to a service center or an experienced tech.

The good news is that the doors are designed to be serviceable and youll probably only have to pay for a couple of small parts, unless the door itself is severely damaged and has to be replaced.

5. Yellow Border on Touchscreen

The Model X touchscreen display has a widespread issue where it eventually starts yellowing around its borders.

Its caused by the glue used in the display panel itself which gets worse over time and when its exposed to heat.

The discoloration is inevitable and will eventually happen to all Model X displays over time.

The Model X uses the same touchscreen as the Model S where this issue is pretty well documented.

The Model S display also tends to form visible air bubbles over time, but this isnt as common in the Model X.

Solution

Tesla service centers can get rid of the yellow border on the touchscreen using a UV treatment device.

Some owners have reported that this treatment sometimes doesnt get rid of the yellowing completely, but it does make it significantly lighter.

You can also get the entire screen replaced, but it will be significantly more expensive.

Upgrading from the MCU1 to the MCU2 infotainment system is also a good option, because it comes with a brand new touchscreen as well.

6. Panel Gap and Paint Issues

Although Tesla has been making the Model X for several years, it still hasnt completely worked out all the build quality issues.

Even new cars that have just rolled off the line are not free from minor defects such as:

• Poor body panel fitment causing inconsistent panel gaps
• Low quality paint jobs
• Leaky seals and weather stripping
• Random creaks and rattles
• Door and window alignment issues

These build quality issues are minor annoyances at most and shouldnt affect the cars overall driveability or reliability.

Of course, build quality and refinement in the newer cars is much better than what youll see in the early production cars, but it still could be better especially when you consider its price.

Solution

The best way to deal with these build quality issues is during the delivery process which is when you should inspect the vehicle inside and out before to make sure it meets your expectations.

You can always take it back to the service center if you find new issues along the way, but that would mean you wont be able to use the car for some time, especially if it needs a respray.

Minor issues can usually be handled by a mobile tech as long as they have replacement parts on hand.

All this should be done while the vehicle is still under warranty so it shouldnt cost you anything aside from your time.
