I have a 2012 Sonata hybrid 94,000 miles. I was pulling into a parking lot on 09/21/2019 when I had a complete brake failure. Thank god, I was only going about 10 mph. Brake pedal went to the floor. Horrible grinding sound from all the wheels. Chiming alarm. "hybrid system warning. Check brakes". Parked the car. Got out and looked all around. No leaks. Checked the brake fluid level, and it was ok. Turned the car back on and no brake dash warnings or chiming. Backed car up and no grinding sound. Called dealer. Hybrid mechanic happened to be near phone. I was told to check brake fluid level and turn car off and on to see if it happened again. Already did that with no problems. Had to drive the car home which was 180 miles away. It makes no sense that everything is working fine now. Had a local brake shop check for leaks, etc. No problems. They plugged into the car's computer, and there were no error codes. Reluctant to take it to the dealer when no current problem exists. Don't want them to just start replacing parts which are very expensive and as much as $3,000 total installed. . Read more...
The driver experienced a stalled engine while driving. The brakes failed to respond and the steering wheel locked up. The car coasted, despite repeated braking attempts, and jumped a curb and stopped when it ran over onto a person's lawn. The driver attempted to steer and stop multiple times. As a consequence, the two driver side tires blew out. The car will be towed to a dealer. A police report was issued.
I was driving with my daughter and took a wrong turn ending up on a dead end street on a hill in sonora. When I put it in reverse turned around then started going forward my entire car and brakes failed without warning. I quickly through on the emergency brake that stopped me from hitting a tree. Thank god it happened there as the next morning I would have been on a 2 lane mountain highway with all 3 of my daughters on a holiday weekend and it could have been fatal. My car has had all services and had just been serviced recently there were no issues and no recalls.
