2019 Honda Clarity problems

“We have a Clarity EV. It has been great for 4 years. But recently, all of the sudden, we started getting system failure messages on the dash. Different systems, including brakes. And the brake pedal went to the floor. I have read about similar failures online at “clarity forum”. Some who posted believe it is a 12-volt battery problem. And Triple A came out and tested it and said the battery is due for replacement Here’s the thing: my mechanic cleared the codes and the car ran perfectly for 24 hours. Before the failures happened again. I took it to Honda, and they insist that the brake system is the problem. And that it’s dangerous to drive the way it is.

“PHEV BURNING SMELL ECON (EV) DRIVING. IT HAPPENED 2 TIMES AFTER THE BATTERY DROPS TO TWO BARS, WHICH MEANS MODE WAS CHANGED TO HYBRID FROM ECON. THERE WERE BIG VROOM SOUNDS FROM ENGINE ROOM WHEN EV MODE CONVERTED HYBRID MODE AT THE SPEED OF 60-70 MPH. EVEN AT THE SPEED OF 5-10 MPH, THE ENGINE SOUND WAS REALLY BIG (IT SOUNDED LIKE REALLY HIGH RPM AT THE LOW SPEED). AROUND 2-3 MIN DRIVING AS HYBRID MODE FROM ECON, I FELT VERY STRONG BURNING SMELL FROM THE ENGINE AREA. I GOOGLED AND FOUND I'M NOT THE ONLY PERSON WHO EXPERIENCED THIS PROBLEM. THERE WOULD BE PROBLEMS WITH EV, ICE, HYBRID SYSTEM. ALSO IT COULD BE FIRE HAZARD WHEN BEING CHARGED.”
