Prior to service in December for the RPP recall, my Volt's all-electric driving range was 45 (winter) to 65 (summer) miles. Now it's zero miles. The gas engine comes on every single time I drive the car. A return visit to the dealer's service department didn't help at all. Any suggestions?

What are the temperatures out? Do you get a message under your speedometer that says "Engine Running Due to Temperature" ??

It's possible that you had your "Engine Assisted Heating" was set to "Very Cold" in the Config menu, and their recall reset the value to the default "Cold" setting, which will run the engine when it's colder than 35F out.

"Very Cold" changes the setting to 15F.

You can also disable "Engine Assisted Heating While Plugged In" in the same menu, which lets you remote start at any temperature when plugged in, and the engine won't turn on. Once you unplug it though, it's still subject to these "Cold" or "Very Cold" thresholds and the engine will come on for a bit.

I think ClarksonCote nailed it. The reprogramming will reset your Engine Assist Heat back to the default 35 degrees. It will also reset the Charge Cord Alarm and Power Interrupted Alarm.

I had to go back in and reset all my settings, specifically Engine Assisted Heating reverted back to ON or 35 degrees. I have noticed NO LOSS in range after having that recall done.

Had my recall done yesterday. Killed my forward cameras. No LKA, no FCA. Took back immediately, and they are going to try again today.
