| Service Brakes problems |
I was driving to work last Wednesday, and I live on a hill. As I was driving, a "brake failure" alert came over my dash and I lost all control of my brakes!!! I live right off of main street, and my options were only to go straight and into a house, or to turn onto main street and hope no one hits me or that I don't hit another vehicle. I turned and thankfully no one was coming. At the end of that street I was able to coast into an closed down gas station and park the vehicle. I called the dealership I had purchased this vehicle from 10 months prior, and they told me I had to use onstar to have it towed to them. I did that, and they towed it to the dealership. The next day the dealership told me the cause of losing my brakes was due to a software update that was needed!!!!! they charged me $800 for the update & a battery that they said was not holding the charge, which I've never had an issue with. I had purchased an extended warranty with this vehicle and I was told it would be a bumper to bumper warranty as if I had purchased it new (it was 2 years old). The dealership said this was not a critical software update and was not covered under any warranty. I could have been killed or seriously injured or killed or hurt someone else due to my brakes going out due to a software update that was needed!! this is insane!.

I went to get in my 2023 Suburban this morning to travel to the gym. It started but it would not shift out of park. I looked down and noticed the check engine light was on, the abs light was on, and the park brake light was on with a lock and wrench. I had no issues since I purchased it used in March 2025 and yesterday it was driving fine.

Failed break fluid detection.
The power steering on the vehicle had failed on December 10th, 2023. The sign was displayed on the dashboard for the vehicle. The vehicle was taken to sunrise chevy and stayed with them for a month for repair and they have been unable to repair the issue. They said the rack and pinion had gone bad on this brand new car. This is very dangerous as the safety of myself as well as others on the road are compromised due to faulty steering problems.
Automatic emergency braking system activated at ~77mph. Essentially I had started braking appropriately and at about the same time the aeb system seemed to conclude more breaking was needed. This led to brief loss of vehicle control when brakes completely locked at high rate of speed ~77mph. According to vehicle manual this system should not activate at speed great than 50mph (photo attached). This is dangerous because I could have lost control and/or someone behind me could smash into me. My vehicle does not have adaptive cruise. Vehicle and other systems otherwise work perfectly. As a side note the extreme brake application at high speed caused cargo within the vehicle to slam forward and destroy the windshield, in addition to being a scary event.
