NHTSA Complaint #11572994 — 2017 CHEVROLET BOLT EV

In Sept 2020, GM issued Service Bulletin 20-NA-170 regarding rapid popping or clicking noises coming from the I-Booster hardware under the hood in the braking system. Earlier fixes for this issue involved replacing the I-Booster hardware, but that didn't solve the problem. The new fix called for a software update to the Brake Booster Control Module. The Bulletin states: "Correction -- DO NOT replace the I-booster assembly. Update the Brake Booster Control Module with the latest software." I reported this brake/electrical system issue to NHTSA on April 24, 2022 (# 11461966) and January 25, 2023 (# 11503678), and have had no response or investigation by NHTSA regarding the hazard of this software defect. When the hardware eventually fails--and it will due to 1000's of unnecessary use cycles--what happens to the braking system?
