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?

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.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
