Chevy Volt Propulsion Power Reduced: Causes, Fixes & System Reset

Buckle up, Chevy Volt owners! So, buckle up for a deep dive into the “Propulsion Power Reduced” message. This annoying notification can shift your smooth sailing into a tense adventure quicker than you can say, ‘electric vehicle.’ But don’t sweat it! Whether you’re racing or cruising the highways, this guide will teach you how to understand, identify and address this common Volt hiccup.

So, let’s charge up those knowledge batteries and prepare to rev up your Volt’s performance back to full charge.

What is it Propulsion Power Reduced?

This warning message is your Volt’s equivalent of “Houston, we have a problem.”

When the propulsion power of your Chevy Volt nosedives, it’s kind of like if your car suddenly decided to run a marathon in flip-flops.

There could be any number of reasons for this loss of juice, but generally, the main problem is the same: Your electric chariot that once glided zippily through the world is reduced to feeling about as fast as a very bad day on the course.

Causes of Reduced Propulsion Power

Let’s pop the hood and see what could be making your Volt lose its mojo.

Battery Issues

The beating heart of your Volt’s electric soul? Your car will tell you — loud and clear — when it’s not feeling quite right.

Over time, batteries can begin to behave like cantankerous old men — they don’t want to hold a charge, they grouse about the weather and they simply can’t deliver like they once could. And this can result in a nasty reduction of your Volt’s power output, with you feeling like you are driving in molasses.

Electric Motor Problems

Your Volt’s muscle comes from the motor. A weak one means your car’s performance is affected.

Electric motors are generally quite reliable, but when they do fail, it’s like trying to run with a pulled hamstring. Problems can vary from worn bearings to burnt windings, all of which can really impede the get-up-and-go in your Volt.

Software Glitches

As Volts and other smart cars have come of age, the problem is now sometimes all in your car’s head.

Just as your smartphone needs a reboot from time to time, the computer systems in your Volt can get a little confused. These software bugs can lead to some strange behavior, including reduced power output. This is like the brain of your car going on an unplanned coffee break.

Symptoms of a Reduced Propulsion Power

Being aware of the symptoms early could spare you pain in the long run, Dr. Clements added.

When your Volt starts to lose its oomph, you’ll know. It may feel like you’re trying to pick up speed in peanut butter, or your top speed may be more appropriate for a Sunday drive than your everyday commute.

The clearest sign, of course, is the dreaded “Propulsion Power Reduced” message appearing on your dashboard like a gatecrasher at a 30th birthday party.

Diagnosing the Problem

It’s time to channel your inner sleuth and figure out why there is less thrust:

Warning Messages

Your Volt is trying to tell you something, and you better listen!

Modern cars do a lot of talking, and your Volt is no different. It will attempt to talk to you with a plethora of warning lights and urgent messages. “Propulsion Power Reduced” is a relatively simple warning, but it may come with company.

Watch out for battery warnings, check engine lights and other colorful disco lights on your dashboard that may occur.

Performance Changes

If your Volt suddenly begins to feel as though you are dragging an invisible trailer, take heed.

You’ve spent a lot of time in that vehicle, yet you know it inside and out. If it starts acting like it’s perpetually climbing an invisible hill or if it takes longer to get up to highway speed than it does to microwave a burrito, then something is up. Your Volt’s version of waving a red flag.

Troubleshooting Steps

Before you call in the cavalry and panic, there are some things you can try on your own.

Basic Checks

Do the basics — sometimes the simplest things bring the biggest results.

Just ensure that your Volt is nicely charged up. It seems obvious, but come on, we all forget to plug in our phones sometimes. Next, look for signs of damage or loose connections.

Occasionally, an issue that appears complicated can be rectified with a brisk once-over and a healthy shove on a connector.

Advanced Diagnostics

If the basic checks aren’t enough, it’s time to get a touch more technical.

The vast majority of modern cars, including your Volt, come with onboard diagnostic systems that will allow you to look under the hood without opening it.

If you happen to have an OBD-II scanner (or a friend with one) to plug in and check what codes come up. The codes can provide a clearer picture of what is happening and how to proceed further.

When to Consider Seeking Professional Help

Sometimes, you know when to hold ‘em and when to call the experts.

If you’ve been through the usual steps and your Volt is still behaving as if it fueled by AA batteries, then take it to a specialist.

That’s especially true if you’re getting warning messages that linger on or if your car is making unusual noises or has severely degraded performance.

Note: With complicated electrical systems, sometimes the best bet is to wave the white flag and let the professionals handle it.

Preventive Measures

As the old saying goes, an ounce of prevention is worth a pound of cure, and this is especially true when it comes to your Volt.

Regular Maintenance

Having checkups will maintain your Volt in top condition.

Just like you (hopefully) visit the doctor for regular check-ups, your Volt requires some TLC too. Follow the maintenance schedule in the owner’s manual. Software updates, battery health checks, or just a general inspection. Like spa days for your ride — it will reward you with years of dependable service.

Driving Habits

Your Volt’s long term health can be affected by how you drive it.

A gentler touch with accelerating and braking can also help keep your battery happy, and your electric motor, too.

Keep away from extremes whenever you can — batteries, like Goldilocks, don’t like things too hot or too cold. And although the temptation will be there to display that instant torque at every stoplight, smooth driving is a much better treatment for your car’s systems in the long run.

Effect on Performance and Safety of the Vehicle

A population of 2010-2015 Chevrolet Volts that have had their power reduced is in for a worry.

A car with less powerful engine might be unable to get into a highway or to climb hills. That can lead you into very unsafe situations.

In addition, if your Volt reduces power significantly, you may end up motoring surreptitiously alogn the shoulder of a roadway, which is never a fun (or safe) place to be.

Costs Associated with Repairs

Beware, repair – making electrical repairs in a hybrid isn’t always cheap.

Repair costs can vary drastically depending on the problem. A routine software fix may cost just a few dollars, while swapping out a battery pack could run you several thousand dollars.

The good news is that several components in the Volt are covered by long warranties so always check your coverage before opening your wallet.

Response and Warranty Coverage from Chevrolet

Chevrolet has your six — most of the time.

Chevy has been relatively aggressive in addressing Volt problems. They have released a number of “technical service bulletins” and extended warranties for specific parts. For example, in most states, parts of the Volt’s electric drive and battery are covered by an 8-year/100,000-mile warranty.

As always, be sure to ask about the latest coverage as well as any recalls or service campaigns that may apply to your vehicle at your dealer.

Just keep in mind that your Volt is a hi-tech machine, and with care and consideration, it could give you many years of efficient and environmentally-friendly transport.

So don’t let a minor setback get you down – all relationships have ups and downs, including the relationship with your car!
