Anyone else getting 'propulsion power reduced' message on their Chevy Volt?

Questions and Support

I’ve recently encountered the ‘propulsion power reduced’ warning message on my Chevy Volt, and it’s becoming quite frustrating. If you’ve experienced this, I’d love to hear your thoughts and solutions!

What does it mean?

From my understanding, this warning generally indicates that the vehicle is limiting its power output, often as a precautionary measure. But what triggers this?

Possible Causes:

  • Battery Issues: It could be related to battery performance, especially if it’s older or has seen better days.
  • Cooling System Concerns: Overheating or issues with the thermal management system can also lead to this alert.
  • Software Glitches: Sometimes, a simple software update can resolve these alerts, so always check for updates.

What I’ve Tried:

  1. Resetting the car’s systems: I’ve done a power cycle by turning off the car and restarting it.
  2. Checking the battery: I noticed my battery wasn’t fully charged, so I made sure it was at optimal levels next time.
  3. Consulting the manual: That was helpful for understanding the warning.

If anyone has more insights or similar experiences, please share! It would be great to pool our knowledge on how to resolve this annoying issue.

I totally feel you, Gary! I had the same problem last month. Turns out my battery cooling system had a small leak.

Have you guys tried running a diagnostic? I got an error code P0A9B which was linked to my motor control module. Not fun to deal with!

Diagnosing that code isn’t straightforward. It could also relate to the high-voltage battery condition. Definitely check connections and voltage levels!

I’ve heard that the Volt sometimes limits power to protect the battery. This happens especially in extreme temperatures. Anyone else notice that?

7

Exactly, JFlores! I’ve experienced reduced power when it’s been cold. It’s a safety feature of the hybrid system.

I think low battery charge can trigger that warning too. Just yesterday, I was down to 10% and got the message. Fill up your tank if it’s low!

That’s a good point! Also, if your Volt has any software updates pending, it could be affecting performance. Always check for those!

Very true, Elizabeth! It’s easy to overlook that. Sometimes I forget about the software maintenance!

11

I just had a mechanic look at it. They mentioned a problem with the regenerative braking system could also cause this error. Workaround or fix?

12

That’s interesting! I had a friend who faced a similar issue, and it was fixed with a simple reprogramming of the system. Worth a shot!

You all are giving great insights! It’s a bit overwhelming, though. Is this something we can avoid in the future with proper maintenance?

Yes, Donald! Regular maintenance can help catch issues early and prevent these annoying limits. Keep an eye on your dashboard and error codes.

Honestly, though, sometimes it feels like the car has a mind of its own. What if it just doesn’t like my driving style? Haha!

Haha, Julie! Perhaps it just doesn’t appreciate your lead foot. But seriously, it could help to have someone check your driving habits if you’re constantly getting that message.

I’ve been getting the ‘propulsion power reduced’ message too! It usually happens on steep hills or when I’m accelerating quickly. It’s definitely affecting my daily commute.

18

Same here! I noticed it mainly in colder weather. The car feels sluggish and it’s frustrating when I need to merge into traffic.

I’ve encountered this issue several times. It usually flashes when I’m driving in eco mode. I wonder if it’s because of battery levels or temperature fluctuations?

That could be it! I read that high temperatures can affect performance too. It’s a bummer when you rely on the car for long trips.
