What are The Common Reasons for Dashboard Crack

A dashboard is one of the most important parts of a car, and it protects the passengers from the elements. But over time, the dashboard can become cracked and damaged. There are several common reasons for this, including exposure to the sun, extreme temperatures, and physical damage.

Exposure to the sun

One of the most common reasons for a cracked dashboard is exposure to the sun. Over time, the sun’s ultraviolet rays can break down the materials in the dashboard, causing it to crack and fade.

Extreme temperatures

Another common reason for a cracked dashboard is exposure to extreme temperatures. Hot weather can cause the dashboard to warp and crack, while cold weather can make it brittle and more susceptible to damage.

Physical damage

Physical damage can also cause a dashboard to crack. If something hits the dashboard, it can crack the plastic or even shatter the glass.

How to Stop a Dashboard Crack from Spreading

If you have a crack in your dashboard, it’s important to stop it from spreading. Otherwise, the crack will become larger and more difficult to repair. 

Dashboard Repair Kit

If you’re looking for a more permanent solution, you can use a dashboard repair kit. These kits come with everything you need to repair a dashboard, including a filler, primer, and paint. 

Apply super glue to the crack

To stop a dashboard crack from spreading, you can apply super glue to the crack. This will seal the crack and prevent it from getting larger.

First, clean the area around the crack with a soft cloth. Then, carefully apply a thin layer of super glue to the crack. Finally, use a piece of tape to hold the crack together while the glue dries.

Stop the crack with a man-made hole

To stop a dashboard crack from spreading, you can create a drilled hole at the end of the crack line. This will prevent the crack from continuing. You can then fill the hole with black filler. The hole you drill should be slightly bigger than the crack width.

Apply silicone automotive adhesive

Put some silicone automotive adhesive on your finger and then wipe it along the sides of the crack. The silicone will dry and become less shiny with exposure to air. This is not a perfect repair, but it’s not too bad.


There is no permanent fix to a cracked dashboard, but you can try using temporary solutions like putting on silicone adhesives. The best solution is to purchase a dash cover to avoid the sore sight of the crack.
