2021 Buick Encore GX Brakes Problems

Brake System Control Module Replacement - The brake system control module needs replacement due to a fault detected with 10 volts on terminal 1. Replacing this component can help maintain proper functionality of the brake system and ensure consistent performance. Why would this all of a sudden be faulty after almost 5 years?

The contact owns a 2021 Buick Encore GX. The contact stated while driving at approximately 35 MPH, the brake pedal was lightly depressed and the vehicle unintentionally came to an instant stop; the vehicle then began to shudder. The contact's mom was seated in the front passenger side of the vehicle and sustained a neck injury after the failure occurred. There was no one injured that was not in the vehicle. No medical attention was required. The vehicle was drivable and was driven to a dealer who did not provide a diagnosis but informed the contact that, the failure may have been occurring due to the Vacuum Module in the braking system needing to be replaced. The vehicle was repaired; however, the failure still occurred. The manufacturer was made aware of the failure. The failure mileage was approximately 2,500.

This week I leased a white buick encore gx fwd in the preferred model. After driving off the lot I noticed the brakes are very hard to press down and I can’t stop the vehicle over short distances. This seems dangerous and my dealership says nothing is wrong with the car but I can tell something is wrong with the brakes and this isn’t how new brakes are supposed to feel. After googling the symptoms it seems to be a problem with the brake booster.

The brake system failed upon pulling into a parking space. Had it happened a few, short moments before, there would have been a high probability of a crash. The vehicle was taken to Hardy Buick GMC Chevrolet. Upon reading the codes, I was told that the vehicle needs a new master cylinder. (It has only 672 miles on it and I've owned it less than 3 weeks.) Numerous lights came on, including: Brakes, ABS, Traction Control, Engine, as well as 2 others. A message came up on the screen that said, "Brake System Failure, 62 MPH Top Speed." There were other messages that cycled that I did not get to make note of, but one made mention of "power steering." Upon research, I found that there are recalls on certain 2021 Buick Encore GX's for an issue related to brake system failure. I was told, based on my VIN number, that my vehicle is not included in that specific recall, however, when my brake system failed, it did exactly as what was described as the potential consequences of the brake failure issue in the vehicles recalled.
