There is a rapid tapping noise coming from the brake booster upon opening the door. Tapping the brakes will make the noise stop. For a few weeks this would stop the noise until the next occurrence after sitting for hours. It has progressed so that the tapping will return as soon as the brake pedal is released and continue while driving. Upon parking, the noise will persist for up to a couple of minutes and then stop. Problem continues. I tried to attach an audio file but it wasn't accepted as an approved file.
2017 Chevrolet Bolt EV brakes complaints

Brakes started making noise at 27,000 miles . We drive in l mode never touch the brakes. Dealership said metal to metal on all 4 wheels. I said that's impossible we don't use the brakes . They wouldn't consider a warranty problem. Raped me for new brakes. $800.

Problem continues to this day (3 march 2021) n.b. It would be nice if one could upload an mp3 of the sound. Thank you!
There are constant strong knocks 8 times per second in ibooster. Knocks are heard in the cabin and under the hood. Disappear only when you press the tomoz pedal.
Unless the brake pedal is depressed there is a rapid ticking noise coming from the master brake cylinder upon opening the door, even without engaging the start button. This sound continues whether the car is stationary or moving under all traveling or stationary conditions unless the brake pedal is depressed slightly. We first became aware, really noticeable, about it upon opening the car door in july, 2020.
Installed chevrolet premium all-weather floor liners p/n: 42686568. While passing on the highway, the accelerator pedal became stuck at full throttle under the liner. Unable to shift to neutral and with minimal slowing from pressing the brakes, I had to reach down and tug on the mat until it dislodged from the pedal. I got off the highway and examined the liner finding that one of the securing clips had come unattached (likely from tugging on it). I reattached and verified correct mat installation. Later while passing another vehicle on the highway the accelerator became stuck again causing uncontrolled acceleration. Examining the mat afterwards, the securing clips were still attached correctly. Additional information: the clips that secure the floor mat/liner are only attached to the vehicle carpet and not rigidly affixed. When correctly installed the lip of the liner rises up and ends with almost no clearance to the gas pedal, then with only a slight movement of the liner it can entrap the accelerator pedal. Over time with forward foot pressure on the liner, there is just enough movement in the liner and clips to allow it to shift slightly forward and to the right causing an interference fit with the accelerator pedal. It appears that when both the accelerator and brake pedals are pressed at the same time, the power to the electric motor continues to be applied. Testing this afterward showed that with a foot on both pedals, the electric power meter still showed power being applied and the vehicle braking performance was severely diminished. During an emergency, a quick flick of the shifter from drive to neutral does not work. The shifter must be held for a longer duration, which is not intuitive when the vehicle is accelerating uncontrollably and both hands are on the wheel.
18k miles in, 1 wheel is getting very hot. Dealer cannot find anything wrong. Has never mentioned it before, but says they recommend regular caliper slide pin cleaning and lubing. Wants $200. If it's a bad caliper, then it should be covered under warranty. They will do nothing. So I have at least 1 non-functional brake at 18k miles. Sounds like a safety hazard.
Chevrolet bolt has "l" driving mode, during which the car will stop if the accelerator pedal is not pressed. However, the rear light does not reliably turn on. If the car is at low speed, or if the car is stopped, the rear brake light may be off. This increases the change of rear collision. When in "l" mode, the break light should be on at all times while the accelerator is depressed.
On a somewhat crowded freeway on ramp, started to accelerate when cars ahead stopped. Fully depressing the brake pedal did not apply maximum braking power. The car slowed but did not stop before colliding with the car in front, despite the fact that there was plenty of room between us for the speed we were going. Later experiments showed that applying the left hand brake control together with the brake pedal applied significantly more braking power and would have stopped the car well short of the collision. Fully depressing the brake pedal should apply maximum braking power, and the hand brake control should not be needed to stop the car as quickly as possible in an emergency situation. I consider this a safety issue, for all drivers whose instinct is to press fully on the pedal, but more importantly for any driver who cannot use the left hand brake due to a disability that otherwise would not impair their ability to drive.
2017 chevrolet bolt. Consumer writes in regards to regeneration during braking feature. *ld
Tl* the contact owns a 2017 chevrolet bolt. While operating the vehicle, a loud howling type noise was present coming from the front end of the vehicle. The vehicle was taken to the dealer (banks chevrolet in concord, nh) who discovered that small stones had become stuck into the braking system between the backing plate and the rotor. The stones were removed and the failure was remedied, but the failure recurred on three separate occasions on both the front driver and passenger side brakes. The manufacturer was notified of the failure. The failure mileage was 1,500. *bf updated 8/2/18
3 times in the first1500 miles small stones have become lodged in the breaking, in both front wheels and never I the back wheels. There is a design defect that allows stones to enter between the backing plate and the rotor. The become stuck (lodged) there and, in addition to creating a loud screeching noise, could impair braking and steering, creating a safety hazard. All this happens when the car is moving.
