NHTSA Complaint #11671074 — 2023 CHEVROLET BOLT EUV

This model has a dangerous driving problem that is difficult to reproduce; however, it points to a flaw in a coupled design that causes simple infotainment system failures to negatively impact both on-star help system and critical driving system. This problem recurred on [XXX] in suburban area of Buena Park CA; previous occurrence in 2024 had purported possible resolution through software download. It begins with simple problem of inability to change FM channel; checking other controls on infotainment screen showed all displays responding correctly, including commands to change station; yet it does not. Only after car has been parked and EV motor turned off for awhile, did this problem reset. This is an indication that previous problem remains unresolved. Previously, on an isolated section of AZ highway without cell service, what began with radio control malfunction ended with this model turning off all speakers and all displays. Once speakers were turned off, on-star interaction can not be heard in the car. I expected separate speakers for on-star emergencies; however, to my surprise it seems to be routed through or related to infotainment system. Then possible stops and attempts to reset the infotainment system through turning off the car, caused all lights to go off on the dash. I had to drive many miles through isolated desert and mountains to reach a safe offramp with no instrumentation. This makes suspect what else could go wrong when in isolated regions. So far the danger seems to be related to driving in no cell service area; however, without further investigation, this design of coupling infotainment system with both critical driving and emergency systems makes this model unreliable and dangerous to everyone in this car. Please investigate and decouple these systems. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
