What Causes Tesla's Sunroof to Fall Off?
2 Answers
It is possible that the issue existed when the owner purchased the Tesla, and as the vehicle is used over time, various components may age, leading to degraded performance. When the vehicle is driven at high speeds, these components may detach from the vehicle. Below are other potential causes: Incomplete vehicle inspection: The owner may not have conducted a thorough inspection of the vehicle. For private car owners, it is common knowledge that regular maintenance is essential, including servicing components after a certain mileage. Negligence during glass replacement: If the sunroof glass was replaced by a third-party authorized service, improper or negligent workmanship may result in insufficient tightening of the glass. During high-speed driving, the vehicle experiences significant wind force, and the resulting impact can exceed the roof's tolerance, potentially causing the roof to detach and fly off.
As a technician who frequently repairs high-end cars, I believe the most common cause of Tesla sunroof detachment is assembly issues. The factory assembly line may not have applied the sealant evenly, or the clips may not have been properly secured. I've encountered several cases where the adhesive aged and failed, especially in cars frequently exposed to direct sunlight. Summer heat can soften the adhesive and reduce its stickiness. Additionally, the sunroof glass itself is quite heavy. If you drive over speed bumps too aggressively or frequently travel on rough roads, the vibrations can loosen the screws. Another often overlooked factor is using high-pressure water jets to clean the sunroof gaps during car washes. Over time, this can deform the sealing strips. All these issues require removing the interior headliner for inspection. I recommend visiting an authorized service center as soon as possible, as a sunroof flying off while driving is extremely dangerous.
