On my Bolt, I’ve noticed an occasional fail of my cabin air temperature control system to regulate temperature. I’ve had to restart the car to clear the fail. If the car was a computer, I would describe the issue as occasional failure to boot up properly. I was wondering if others have seen this issue?

Temperature Control Fail Symptoms:
The car starts normally. The cabin blower turns on, but at minimal speed. But the system does not seem to regulate the cabin temperature. This problem is most noticeable on a warm day. I have the temperature control set to Auto, 72 F. I can drive the car for a moderately long time and it seems to stay stuck in this mode of no temperature regulation and minimal air flow. If I turn the car off, then restart it, the air temperature control works properly.

During normal operation on a warm day, a few seconds after I start the car, the blower turns on and forcefully blows cool air to lower cabin temperature. As the cabin temperature lowers, the system adjusts fan speed and air temperature. None of this happens during a fail.

The temperature regulation fail does not occur on a consistent basis. I’ve noticed it about once a week. It is possible it is happening more frequently. But with mild California temperatures, I may not be noticing that the system is failing to regulate cabin temperature.

Have you reported this to GM? Probably a good idea to do so, to help them identify any potential issue and get a software update rolled out.

If it's a recurring issue you can easily replicate I would urge you to visit your local dealer to get this anomaly captured in their vehicle service database. Could help find and fix a bug early on before it impacts THOUSANDS of Bolt owners.

The fix could be a software update.

I had an issue with my Volt with no heat, probably once or twice a month. A software update fixed that. So definitely report it, and get some engineer working on a fix if it hasn't been reported yet.
