The 2021 Ford Bronco is one of the most anticipated cars in recent memory. First of all, it was a great idea that seems to have been executed in a way that was destined to make Bronco fans happy. Secondly, the COVID-19 delays and production struggles have dragged out the deliveries, making it more anticipated. However, now that the 2021 Ford Broncos are delivering, there are already some annoyingly noisy issues that Ford is working to fix.

Is the 2021 Ford Bronco a good truck? 

Ford has been struggling to get the 2021 Ford Bronco together for nearly a year now. The Bronco has been hit with delay after delay. Now that the Ford Bronco is bucking around trails, customers are finding some concerning and annoying issues. 

Customers are reporting that driving the new Ford Bronco over 30 mph triggers a whistling sound that stains the excitement for the new 4×4. In response to this annoying issue, Ford has posted a service bulletin to address this whistling sound. So far, the issue has been mostly localized to the Big Bend, and Outer Banks trims. 

What’s causing the Ford Bronco issue?

According to CarScoops, a screenshot of the TSB was shared on Bronco6G, a Ford Bronco forum. The service bulletin mentions that the whistle noise can be eliminated by sealing off the gap between the hood and the grille opening. It would seem there may be an issue with the hood seal design. 

Although that is a simple enough fix, Ford isn’t going to stop there. Ford has announced that it will be working on a new hood design that should eliminate the whistle once and for all. With any luck and no more factory shutdowns or production delays, Ford hopes to get these new designs on the new Broncos by October 2021. 

The service bulletin also instructs dealers to tell customers that the trucks are still perfectly safe to drive, and once the new hood comes in, they will be notified, and the new hood will be installed. 

But what if the hood isn’t the issue?

Some members of the forum have speculated that the hood and grille aren’t the problem. Some users speculate that the whistling is coming from the wing mirrors. *It should be noted that forums are not always the most reliable source of information. There is no guarantee that these commenters even own a Bronco or have even ever driven one.*

Either way, whether the hood and grille seal or the door mirrors are to blame, we will have to wait for the new Bronco hoods to see if it fixes the issue. 

This isn’t the first Bronco issue

The Ford Bronco Sport has already seen two recalls, but since the baby Bronco is a good bit different, we won’t worry about that. The 2021 Ford Bronco was delayed because of the removable hardtop production delays. Well, they should have taken a little more time to build them. Along with the annoying whistle, Bronco owners also complain about the roof panels delamination after only a few weeks. 

While the 2021 Ford Bronco is still one of the most exciting new cars we’ve seen in a while, Ford better hope there aren’t any more issues, or else the Bronco might start to get a reputation.
