Driving down the street after a short trip this morning with no one on the road in front of us the vehicle had an alert like we were about to impact someone and braked pretty hard 2x back to back with the collision alert popping up. The person behind us had to slam on their brakes and barely avoid hitting us. There was nothing in front of us. This vehicle is dangerous to everyone around us and should be taken off the road.
Completely lost all power brakes while on the road today. Owned it for about 11 months. Looking like the master cylinder. We've been having random electrical issues when we're cranking it up. Weird sound coming from the dash when the ac is on on occasion. Like the car wasn't fully kicking over even though the engine was running. Sometimes turning it off and turning it back on would make it work.
I wanted to update a previous report. The vehicle had had some odd electrical issues. The brakes ended up failing while driving but no electrical issues at the time proceeding it. What I wasn't able to report before was that the brake pedal sunk to the floor with no effort to stop the vehicle at all. The emergency brake is a button on the left side of the vehicle which was attempted to be engaged to stop. It made no effort to stop whatsoever. The vehicle is a danger to society. I just got it back from the dealership and they made an update to the computer or console but replaced no parts. These all need to be recalled no one should be driving these.
Brake pedal went to the floor 1 time when starting vehicle at approximately 400 miles.
