Grades: Service coordinators A, Mechanics C, Service Manager F I hate to bash the dealership in my review because I don't want to adversely affect the service coordinators for what is obviously a problem at a higher pay grade.

They did their best to make sure I got my car, and get me a loaner, and keep me informed of the lack of progress.

It actually makes me anxious and irritated to drive ICE vehicles now.ĭespite my anger with the dealer for a) not listening to me on Monday and getting the damn part ordered, b) not touching the car until Thursday, and c) still not having a full diagnosis or a repair plan on Friday, the service coordinators are great. On Friday, they were waiting on a call back from GM about the source of the mystery tap-tap-tap noises. They did not touch it until Thursday (I called every day, but clearly this dealer had organizational and scheduling challenges). Dropped my car off at GM Dealer #2 on Monday morning. Car goes in on Monday to a different dealer, and hopefully we can get that taken care of.Įmail me at if you want a video recording of the sound from inside and under the hood of the car.Īn update.

A wise individual on the Bolt FB page suggested it was the iBooster earlier.Īnyway, just wanted to post here so others knew the tap-tap-tap is a thing, and the iBooster is clearly marked with a label and bar code beside the brake master cylinder. GM was unable to diagnose it the first time but I have a really nice video recording of it clicking and I had the hood up so I could feel around the brake cylinder and assembly and it was certainly coming from there. I have even had times where it starts tapping when I shut the car off. Now it is up to 30+ times (tap-tap-tap-tap.). When it started, it would click 5-6 times. The noise generally stops when I press the brake pedal. I too have a 2017 Bolt, and it is making a strange clicking or tapping noise when I enter the vehicle.
