When I decided to buy my first car, just last year, I wanted it to require as little maintenance as possible. My goal was to have a way to move around, not to have an unreliable source of headaches.
Before deciding to go for an electric vehicle, I considered a “traditional car”. But in the end, I went for the Renault Zoe. My choice was based on many reasons but one of them was the reliability of the motor.
Electric motors tend to be better than combustion engines.
For starters, they have fewer moving parts, so fewer parts that can break. Then, the parts they do have require less maintenance. It’s ideal for someone who wishes to avoid unpleasant visits to the repair shop at some point in the future.
In the year that I’ve had my Renault Zoe, the motor didn’t give me any problems, and I truly hope it stays that way!
But electric motors are not entirely immune to failure. As with any other component of a car, it needs proper maintenance and care to function properly.
In this article, I’ll go deep into that topic. It will be helpful for those of you who had the unfortunate experience of having a motor failure on your Renault Zoe. But also for those who want to know how to avoid this problem altogether.
First, we’ll identify potential signs of motor failure. Then, we’ll debate the possible causes for this to happen and what you can do to avoid reaching the point of failure. Finally, we’ll review some suggestions you can try in case you’re experiencing motor failure on your Renault Zoe.
Signs of Electric Motor Failure
Although rare, an electric motor failure is a serious issue. So, as an EV owner, you should stay alert to the signs that your electric motor may be failing. Catching the issue early can prevent further damage and save you from expensive repairs or replacements.
Common signs of electric motor failure in the Renault Zoe include:
- Warning lights on the dashboard: This is one of the most obvious signs. These lights may show different problems, be it with the motor, the battery, or other electrical components of the car. If you notice warning lights, check the manual to see if these are related to the motor. Follow any instructions mentioned in the manual for that specific problem.
- Unusual noises: Another sign that should put you in alert mode is if you hear unusual noises coming from your car. These may include whining, grinding, or buzzing sounds coming from the motor or elsewhere in the car. The noises may indicate that the electric motor is not functioning properly, and you should investigate them to prevent further damage. You can hear one of such noises on this Youtube video.
- Loss of power: If you notice that your Zoe is not accelerating or moving as quickly as it used to, it may be a sign of electric motor failure. The loss of power may be gradual or sudden, but either way, you should have it checked out to ensure both your car’s health and your safety on the road.
- Reduced range: If you notice a significant loss of range on a single charge, you might be dealing with electric motor failure. This might also be due to several other factors, but it’s important to rule it out.
If you notice any of the signs above, investigate thoroughly. This way, you’ll either rule out electric motor failure or be able to address the problem.
Now that we’ve identified the main signs, let’s understand why a motor can fail in an electric vehicle.
Causes of Electric Motor Failure
Despite electric motors being simpler than combustion ones, they are motors after all. That means that they’re complex machines and there are many factors that can cause them to fail.
As a Zoe owner, it’s important for you to be aware of these causes just so you can prevent any issues and keep your car running smoothly.
Let’s look at some of the most common causes of electric motor failure in the Renault Zoe:
- Overheating: Electric motors generate a lot of heat when they’re on, and if they become too hot, they can fail. Overheating can be caused by a number of factors. These include a lack of proper cooling, driving in hot temperatures, or a malfunctioning cooling system. To avoid overheating, make sure your cooling system is functioning properly, and avoid driving in extreme temperatures whenever possible.
- Lack of maintenance: Like any car, the Renault Zoe requires regular maintenance to keep it running smoothly. This maintenance includes, for example, doing oil changes, tire rotations, and brake checks. Follow your car’s recommended maintenance schedule to prevent these issues.
- Battery issues: This is an essential component of any electric car, and if it’s not functioning correctly, it can cause electric motor failure. Battery issues can happen because of several factors, including a lack of proper charging, damage to the battery cells, or extreme age.
- Manufacturing defects: Although a not-so-common case, your Renault Zoe’s motor might fail due to manufacturing defects. These defects may be related to the motor itself or other components of the car. If you suspect that your car has any of these, contact your dealership or the manufacturer to have it inspected.
By being aware of these causes of electric motor failure, you can take steps to prevent them and keep your car’s motor healthy. Now, let’s look at some ways you can proactively prevent motor failure on your Renault Zoe.
What to Do if Your Electric Motor Fails
Despite your best efforts to prevent electric motor failure, it can still happen. If you are in such a situation with your Renault Zoe, here’s what you need to do:
- Pull over safely: If you notice any signs of electric motor failure while driving, pull over safely and turn off the car. You should stop immediately. Don’t attempt to drive to the nearest repair station, as this could compromise your safety.
- Call for assistance: Once you have pulled over, call for assistance. Depending on the severity of the issue, you may need to have your car taken to a qualified mechanic or dealership. You can find the assistance number for the UK here.
- Do not attempt to repair it yourself: Electric motor failure is a complex issue and, unless you’re a mechanic or technician, you shouldn’t attempt to do the repair on your own. If you do, you might cause further damage to the car.
- Be prepared for potential costs: Depending on the severity of the issue, electric motor failure can be costly to repair. Be prepared for this and consider whether your car is still under warranty or whether you have extended coverage that can help cover the costs.
How to Prevent Electric Motor Failure
As we stated above, electric motor failure is a serious issue, so you should strive to do everything in your power to keep it from happening. Luckily, there are a few measures you can take:
- Follow the recommended maintenance schedules: Regular maintenance, such as oil changes, tire rotations, and brake checks, can help keep your car running smoothly. They will also help prevent issues that could lead to motor failure.
- Keep it cool: As we saw, overheating is a common cause of electric motor failure, so it’s important to keep your Renault Zoe cool. To achieve this, ensure that your cooling system is functioning properly, avoid driving in extreme temperatures, and use the car’s air conditioning system as needed.
- Follow proper charging procedures: Be sure to use the correct charger for your Zoe, and avoid overcharging or undercharging the battery. If you want to learn more about common battery issues, we have a guide for you here.
- Drive carefully: Careful driving can help prevent electric motor failure by reducing wear and tear on the car’s components. Avoid sudden starts and stops, drive at a reasonable speed, and avoid driving on rough roads whenever possible.
- Address issues as soon as they arise: If you notice any signs of electric motor failure, such as the ones described above, have them addressed promptly by a qualified mechanic or dealership. If you ignore these signs, it can lead to further damage and more costly repairs down the line.
As we’ve seen, taking good care of your Renault Zoe’s electric motor is crucial to guaranteeing the longevity and safety of your car.
Do regular maintenance, cool your car properly, charge it as recommended, and drive carefully. If you do all this, you should be able to avoid a condition as serious as electric motor failure.
However, if it does happen, at least now you know how to identify the problem, and what to do to fix it.
The most important thing to remember here is: don’t try to fix it yourself.
Always have the car looked at by a professional who can help you properly fix the problem.
I hope you won’t ever have to deal with electric motor failure but, if you do, I hope the solutions in this article will be of help.
