NHTSA Complaint #11680241 — 2017 CHEVROLET BOLT EV

This tends to only happen below 74 degrees Fahrenheit and happens excessively between 72 and 74 degrees Fahrenheit. While driving with one pedal engaged (labeled as low on the shifter since they re-used another model's shifter for the first several years of the Bolt EV), the cruise control will randomly disengage and force the vehicle to immediately slam on the brakes. Usually its not a big deal, but when it happens at highway speed as you're just passing a semi or large vehicle and merging back into the lane in front of it, it becomes dangerous very quickly, which has happened a couple of times now. I would venture a guess that its not related to the cruise control directly, but some system that its relying on is forcing it to deactivate the cruise control. The only other issue this vehicle is having that might be related is that the blind spot detection system is not working correctly on the left side. I know there's a TSB for the aluminum Butyl tape becoming damaged or missing, but if that's causing my car to slam on its brakes in front of fully loaded semis, Chevy should probably be persuaded into re-coding how their cruise control gets disengaged. Especially since this blind spot detection system issue seems somewhat common. Either way, something is causing my car to randomly slam on its brakes in the middle of the highway and Chevy says there's nothing they can do about it because its not setting a code. This is definitely a dangerous safety issue that they should be forced into actually diagnosing more than just plugging a computer in and saying: "whelp, nothing to see here." and returning it to the customer with a "we can't do anything, sorry."
