My 2017 Bolt has experienced the brake booster failure problem. For those not aware this manifests itself as a thumping noise that occurs after the car has been sitting for a while. The thumping will start when the door of the car is opened. It will go away ( initially) if the brake pedal is...

The technical bulletin for this item 20-NA-053 states " Using SPS verify if the vehicle has the latest calibration in the K114B Hybrid / EV Powertrain control module 2." The bulletin continues - (paraphrasing): If not up to date - update module 2. If up to date give the car back to the...

The Bolts new battery has arrived at the dealer. They have sent me lots of images. Very interesting for me. It is a brand new battery with the new style of cooling connections. GM customer care has been contacting us periodically to ensure we are informed and comfortable with what is going on...

So my Bolt went back to the dealer for actual battery capacity testing. It had to stay overnight. They gave me a loaner rental car. Next day - The dealer service manager communicated that the battery testing was completed and that cell 29 voltage indicated a problem. He said they were...

The Bolt went into the dealer and had the "battery capacity reset" procedure done. It stayed overnight while this happened. After the procedure the service manager and I took a set of readings on the car using the torque - pro to get the data from the OBD2 port. On my way home it was noticeable...

I heard back from my dealer 2 days ago and we had a phone discussion yesterday. I am pleased we are moving forward. We discussed the Bolts symptoms and why I believe that the battery needs diagnosing. They stated the first step of diagnosis is to bring the vehicle in and leave it overnight...

I continue not hear back from Chevrolet about my Bolt's lack of battery capacity problem. Although I resent having to do it I have set myself up to get battery data from the OBD2 connection. I had to load a very invasive Bluetooth emulator program into my PC and purchase TorquePro. I also needed...

This not a range issue - although the indicated range is reduced. The issue is battery capacity. I think what I am up against is the fact that I live in Manitoba. As I understand it GM has the policy of not selling Bolts in areas that do not give a rebate of some kind to purchase one. Manitoba...

A few weeks ago we were coming home in our Bolt. The State of Charge meter was indicating 25% full. The vehicle gave us a low power remaining / propulsion power reduced warning and slowed the car. The SOC bars turned orange and black and started to disappear. Within 3 Km we were dead beside...

Hi devbolt, Thank You. Horn chirps turned off. Now able to turn off / unplug car in mid charge without a horus of chirps erupting. Yay!!!!! Will

I have ordered an OpenEVSE charger. I am hoping that when I turn it off (sleep) that the Bolt will not chirp. I am an Arduinoist so the Opensource charger will work well for me. I do not understand why one would build an EV that if the utility turns off charging with OnStar it does nothing but...

The Chevy Bolt design has the vehicle chirp repeatedly if the power should go away (power failure) before the car is fully charged. This gives me problems as I live off grid and usually cannot charge the car in one day. Also my control will stop the charge if there is not enough power or there...
