2. Common Bakflip Mx4 Problems And Solutions

Undoubtedly, the Bakflip is a robust, functional, and commendable choice. However, like any product, it is not without its drawbacks.

If you’re considering purchasing a Tonneau cover, it’s important to be aware of the potential challenges. This knowledge will assist you in finding the ideal Tonneau cover for your cargo bed, tailored to your specific needs and requirements.

Common Bakflip Mx4 Problems And Solutions (Source: Internet)

Issue 1: Leakage from MX4 Cover

One of the most prevalent problems encountered with the MX4 cover is undesired leakage. Numerous users have reported noticing leaks after a few months of usage, and there have even been instances where online shoppers received covers with leaks.

The majority of leaks occur at the tailgate, although they are usually small enough not to soak the cargo. Nonetheless, this poses a risk of potentially damaging goods during transportation. It is indeed disappointing to experience leaks in a supposedly new cover.

Despite being a reputable brand, BAK disappoints some customers by explicitly stating that their MX4 cover is only water-resistant, not waterproof. Consequently, they cannot guarantee absolute protection against water leakage for your cargo.

To mitigate this issue, BAK incorporates a rubber seal system intended to keep water away from the cargo bed. However, the correct installation of this rubber system is crucial for enhancing water protection. Should the seal be loose or improperly installed, it becomes a vulnerable entry point for water, which could lead to damage to your goods.

Given the availability of alternative brands in the market that offer leak-free performance over extended periods, many people opt to avoid the MX4 cover altogether. Particularly for those residing in rainy areas or regularly dealing with water exposure, it might be best to steer clear of the MX4.


To address the leakage problem, you can take the following steps:

  1. Identify the locations of leaks and seal them effectively using butyl putty.
  2. Consider adding an extra drainage system to direct rainwater away from the cargo surfaces during heavy rain.

Issue 2: Rail Trucks Clamps Problem in MX4 Cover

Regrettably, the MX4 cover by BAK is equipped with substandard clamps, which leads to an insufficient connection with the cargo bed rails in rail trucks. As a consequence, the cover fails to provide complete protection against the sun, snow, or potential theft.

Furthermore, the MX4 suffers from defective latches that do not operate smoothly, making it challenging to fold the cover back and forth.


To address the clamp issues, it is recommended to reach out to BAK customer support and request a replacement. By doing so, you can resolve the problem with the clamps and ensure a secure connection to the rail trucks, thereby enhancing overall protection.

As for the problematic latches, applying lubrication can be an effective solution. This will facilitate smoother sliding over time, making it easier to operate the cover and fold it without undue effort.

Issue 3: Incorrect Fitting

The MX4 cover’s performance and protective capabilities rely heavily on the correct fitting. Ensuring that the cover is fitted properly on your cargo is crucial to avoid potential problems.

Opting for installation directly from the dealer is recommended as they are experts in fitting the cover appropriately. However, if you decide to make an online purchase, there is a high probability of encountering incorrect fitting issues since you may not have the necessary expertise.

The design of the Bakflip MX4 tonneau cover, particularly at the tailgate, adds to the complexity of achieving precise fitting. Failure to fit the cover accurately can result in issues such as leaks or other functionality problems.


To address the fitting problem, it is advisable to take the following steps:

  1. Before purchasing the Bakflip MX4 cover online, communicate with the dealer and inquire about the availability of installation services. This ensures that you have professional assistance in fitting the cover correctly.
  2. If the online dealer does not provide installation support or if you lack confidence in your ability to achieve the right fitting, it may be best to refrain from buying from them. Opt for a dealer or seller who can offer fitting assistance to avoid potential fitting-related issues.

Issue 4: Inadequate Customer Service

When purchasing a tonneau cover, the expectation is to receive long-lasting bed protection along with friendly and efficient customer support to address any potential issues that may arise from regular usage.

BAK offers a commendable 5-year warranty for their products. However, the customer support team fails to meet expectations. Trying to reach out to an agent feels like an arduous battle, as they are unresponsive and lack cordiality in providing after-sale services. As a result, obtaining solutions from BAK’s customer support becomes a challenging task.


To rectify this issue and improve overall customer satisfaction, the brand must prioritize enhancing its after-sale services. This can be achieved through the following measures:

  1. Conduct training sessions for their customer support team to ensure they are equipped with the necessary skills and knowledge to deliver top-notch service.
  2. Strengthening communication channels to ensure that calls are promptly answered and customers’ concerns are addressed with care and respect.

If BAK fails to address this aspect and neglects to improve its customer service, it risks losing market value and popularity among consumers.

It is essential to acknowledge that while there are some negative aspects of the Bakflip MX4 tonneau covers, they also possess excellent features. Now, let’s explore some of the upsides of the Bakflip MX4 cover.

Issue 5: Concerns about Materials Used

In recent times, numerous users have expressed their dissatisfaction with the MX4 cover, citing that it contains more plastic components than aluminum. BAK has acknowledged that they made changes to their design and materials in an attempt to enhance the cover’s protective capabilities.

However, this alteration proved to be a setback as they opted to replace aluminum parts with plastic, resulting in a decrease in overall quality rather than an improvement. This change disappointed customers who were familiar with the older model. The newer version is notably less sturdy and feels flimsier compared to its predecessor.


To avoid encountering these material-related issues, it is advisable to explore alternative tonneau covers made primarily from aluminum. Opting for aluminum-made covers is more likely to ensure long-lasting and robust performance, meeting the expectations of durability and protection. By doing so, users can avoid the shortcomings associated with the MX4 cover and enjoy a better experience with their chosen tonneau cover.

Issue 6: Incomplete Closure of the Cover

If your tonneau cover fails to close entirely, there could be several reasons contributing to the problem. Here are some potential causes to consider:

  1. Obstruction: Firstly, check if there’s anything blocking the cover from closing properly. Remove any obstacles that might be hindering its smooth operation.
  2. Misalignment: The issue might lie with the cover itself. It’s possible that the cover is misaligned, which could prevent it from closing correctly. You can attempt to adjust the alignment yourself to rectify the problem.
  3. Damaged Gas Struts: Another potential cause could be damaged gas struts. These struts assist in the smooth opening and closing of the cover. If they are compromised or worn out, they will need to be replaced to restore proper functionality.


  1. Check for any obstructions and remove them to ensure unimpeded movement of the cover.
  2. If misalignment is suspected, try adjusting the cover carefully to ensure it fits properly and closes completely.
  3. In the case of damaged gas struts, replace them with new ones to facilitate smooth and reliable cover operation.

Issue 7: Noise from the Cover

When your tonneau cover starts making noise, the likely cause is damaged seals. To address this issue, you can attempt to replace the seals yourself. However, if the noise problem continues even after replacing the seals, it may be necessary to consider replacing the entire cover.

Issue 8: Difficulty in Opening the Cover

Encountering difficulty while trying to open your tonneau cover may have a couple of potential causes:

  1. Damaged Gas Struts: One possibility is that the gas struts, responsible for facilitating the smooth opening of the cover, have been damaged or worn out. In such cases, replacing the gas struts becomes necessary.
  2. Insufficient Lubrication: Another reason could be inadequate lubrication, causing friction and hindering the smooth movement of the cover. To address this, you can try lubricating the cover yourself.


  1. If you suspect damaged gas struts, have them replaced to restore effortless cover operation.
  2. Check the lubrication levels and apply lubricant as needed to ensure smooth movement of the cover.
