Brake Sensor problems of the 2015 Hyundai Sonata

Hybrid system warning. Check brakes. Do not drive. The car shuts down while you are driving and you get this warning with alarms dinging loudly. It renders the car unusable and is unsafe in traffic. If you turn the car off and wait you can restart it but it just happens again. It happens on the freeway at high speed and on slow side streets. Took it to the dealer and they said it was a sensor in the brake booster so we replaced it. A week later it happens again. About a year before we got a similar message: hybrid system warning. Do not drive. But it didn't say anything about the brakes. Happened multiple times at varying speeds in all weather. The dealer replaced the 12v battery and the message stopped. Now we get the brake problem instead. This is very unsafe as your car shuts down at high speeds! dealers appear to have no solutions that are correct. It is a common complaint on Hyundai owner forums. See the following: https://www. Hyundai-forums. Com/threads/2018-sonata-hybrid-hybrid-system-warning-safely-stop-and-do-not-drive-warning. .
