Why is my Ford Mustang Mach-E making a knocking sound?

If you're experiencing a knocking sound coming from your Ford Mustang Mach-E, it's essential to address this issue promptly to ensure the optimal performance and longevity of your electric vehicle. At McFarland Ford, we understand the importance of diagnosing and resolving unusual sounds in your vehicle, so today we’re going to dive into why your Ford Mustang Mach-E might be making a knocking sound and what steps you can take to address it.

As the Ford Mustang Mach-E is an electric vehicle, knocking sounds could potentially be related to the battery or electric motor system. Issues such as loose connections, faulty components or abnormal vibrations in the electric drivetrain can manifest as knocking noises. It's crucial to have the electrical system thoroughly inspected by our certified technicians at McFarland Ford.

In some cases, knocking sounds in a vehicle can be related to suspension or drivetrain components. Loose or worn suspension parts, such as bushings or struts, can produce knocking noises when driving over bumps or rough terrain. Similarly, issues with the drivetrain, such as worn CV joints or driveshafts, can also result in knocking sounds.

While those are the top causes of a knocking sound in the Ford Mustang Mach-E and similar electric vehicles, there are plenty of other sounds that your vehicle might be making as a warning sound.

• A clunking sound when applying pressure to the brake pedal typically accompanies worn down components in your braking system. It might be time to replace your rotors and/or pads.
• A grinding or whirring sound whenever you shift between gears, such as from park to drive might mean you have an issue with your transmission system. Your oil might be low, meaning you could be dealing with a leak, or a wheel bearing or CV joint could be worn down. Alternatively, if the sound is happening while applying pressure to the brake pedal, it could once again be a sign of worn down brakes.
• A rattling sound from beneath your vehicle could either mean that something in your undercarriage is loose that shouldn’t be, or that something that shouldn't be there at all has lodged itself in there.

The underpinnings of an electric vehicle like the Ford Mustang Mach-E are drastically different from those of a traditional vehicle. Many of the sounds and warning signs you might notice in a regular vehicle don’t apply to EVs as they don’t have the components that make them. For example, your Mach-E should never make a squealing sound from beneath the hood, because there are no belts powering your air conditioning or power steering. So, what are some other warning signs that something might be wrong with your EV?

If you notice things like dimming headlights, flickering interior lights, interference with your audio and other electrical systems or unworking windows, something might be wrong with your electrical system. This is the biggest warning sign drivers have noticed with electric vehicles like the Mach-E. Although electric vehicles have been around for several years now, the boom in electrification is still in its infancy, so drivers haven’t had as much time to discover and diagnose issues.

If you’re noticing other things with your that weren’t touched on here, don’t hesitate to get in touch with us here at McFarland Ford. We’ll do our best to diagnose any issues that you might be experiencing. And if you do notice one of the issues here, it’s important not to ignore it. Schedule a diagnostic appointment with our expert technicians to identify the root cause of the knocking noise – or anything else – and implement the necessary repairs or maintenance to keep your Mustang Mach-E running smoothly and quietly on the road.
