Open the full vehicle complaint log (all categories)I was driving on a highway access road when my Chevy Bolt's automatic emergency braking system suddenly and unexpectedly applied the brakes. I have noticed that the proximity warning system is fairly sensitive - often beeping even when I am applying brakes to decelerate at a rate that feels comfortable and reasonable to me given the distance of the vehicle in front of me. In this instance, however, there was no beeping of the warning system. Additionally, I was not closing the distance between my vehicle and the one in front of me, nor were they braking. I was concerned that the unexpected and unnecessary emergency braking could have caused me to be rear-ended had a vehicle been behind me. It was very heavy braking - disproportionate to the distance and speed between myself and the vehicle in front of me.
Rainwater leaks through the rear windshield wiper grommet and runs down into the trunk shorting out the amplifier that is located at the bottom underneath the tire change kit. Collision alert sounds and turn signal sounds do not function because the amplifier is shorted out. There is no visible sign of water leak unless you disassemble and entirely remove 1) the top trunk cargo liner, 2) lower trunk charger compartment liner, and 3) large styrofoam tray with tire change kit. Water pools around the amplifier corroding terminals and shorting out the amplifier creating an electrical shock hazard. There are no drainage holes in the trunk well so rainwater has no way of draining.
THIS FRONT COLLISION WARNING SYSTEM DOESN'T WORK WELL, TODAY I WAS DRIVING ON A CAR POOL LANE AT A SPEED ABOUT 65-70 MPH, A WHITE FORD EXPLORER SUDDENLY CUT IN, THE SYSTEM DIDN'T MAKE ANY WARNING OR BRAKE AT ALL. I HAVE A DASH CAM RECORDED IT. WHEN THIS HAPPENED, IT WAS SUNNY, CLEAR DAY, ON A STRAIGHT FREE WAY. AFTER A WHILE, WHEN I LEFT THE FREE WAY, THE SYSTEM STARTED TO MAKE WARNINGS WHILE THE SPEED DROPPED TO 50 MPH.
