| Description of the problem | 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. Found identical issues reported at https://www. Hyundai-forums. Com/threads/brakes-failure-on-sonata-hybrid. 155580/page-4 along with shared concern about what happens when you're traveling down a steep hill at 75 mph and the same thing happens? |
