Why Does My Car Smell Like Burning Rubber After Driving?


If your car smells like burning rubber after driving, don’t ignore it. The reason could range from a burning foreign object to a burnt clutch. There are good smells, and there are bad ones. Grandma’s freshly baked cookies? Good. That first cup of coffee in the morning? Great. Burning rubber in your car? Bad. If you’re asking yourself: “why does my car smell like burning rubber after driving?” – then you’re in the right place as this guide will help you troubleshoot and even fix this exact issue.

Here are the 8 most common causes:

  • A hose is worn or loose
  • There’s an electrical short somewhere
  • Your engine is burning oil
  • You’re leaking radiator coolant
  • Your drive belts are getting hot
  • A foreign object is burning
  • Your brakes are hot
  • The clutch is going out

Noticing the smell of burnt rubber coming from your car does not always mean there’s a huge problem. But it does suggest that something needs your attention. Thankfully, if you take care of the issue early, you will most likely prevent it from becoming worse in most cases. Let’s get started with the basics right away!

Top 8 Reasons Your Car Smells Like Burnt Rubber After Driving

Reason #1: A Hose Is Worn Or Loose

Why Does My Car Smell Like Burning Rubber After Driving?

A car engine creates a lot of heat, especially if it has been running for a while. This may lead to one of the interior hoses getting melted. Not all of the hoses in your car are made of the same thing, so if any of them are worn, loose, or burnt, they won’t always carry the smell of rubber. Thankfully, when a hose goes, there will likely be other indicators other than a burnt rubber smell. Some of these include a loss of pressure, white smoke, or a puddle of liquid on the ground.

Reason #2: There’s An Electrical Short Somewhere

Why Does My Car Smell Like Burning Rubber After Driving?

If you notice the smell of burnt rubber coming from your AC vents, but it goes away shortly after, you may have an electrical short somewhere. The smell is likely due to a fuse burning out, which, thankfully, you can check by opening the fuse box and scanning for any that have blown. You should be able to find replacement fuses at an auto parts store for less than a dollar each. If the same fuse happens to blow again, there’s likely an issue elsewhere, meaning you may need to take it to a shop to track down the cause.

Reason #3: Your Engine Is Burning Oil

Why Does My Car Smell Like Burning Rubber After Driving?

Here’s one you don’t want to neglect – an oil leak. The reason an oil leak will smell like burnt rubber is that when it lands on a hot engine component, it gives off a unique scent. What causes an oil leak? Well, lots of things, but the most likely cause is a worn gasket or seal, which is something you don’t want to ignore.

When your engine has an oil leak, there’s a good chance it’s not receiving enough to stay lubricated, which will cause it to overheat. This can lead to several severe issues, like a blown head gasket or a cracked engine block.

Reason #4: You’re Leaking Radiator Coolant

Why Does My Car Smell Like Burning Rubber After Driving?

Here’s another one that stems from a leak, except this time, it’s caused by coolant seeping out on to hot engine components. While rubber is not the actual cause of the odor, it does resemble something akin to the smell of burnt rubber.

Similar to the last reason, you don’t want to ignore a coolant leak. Otherwise, your cooling system won’t be able to function correctly. When an engine gets too hot, disaster can occur, such as a crack in the block developing or the head gasket blowing.

Thankfully, you should be able to notice a coolant leak by looking for a puddle of green or orange liquid underneath. There may also be some on the bottom of the radiator. You can find this crucial part at the front of the engine compartment.

Reason #5: Your Drive Belt Is Getting Hot

Why Does My Car Smell Like Burning Rubber After Driving?

Many different parts receive power from the drive belt, like the water pump, alternator, AC, and power steering system. If any of these parts develops an issue, it can affect the rotation of the drive belt, which leads to excess friction being created. Where there’s an increase in heat, there’s the chance of something getting burnt, and in this case, it’s the drive belt.

A decent way to be sure it’s your drive belt is to listen for a squealing sound coming from under the hood. In this case, you may only need to replace the belt, though, in some instances, the failing part may need to be swapped out as well.

Reason #6: A Foreign Object Is Burning

Why Does My Car Smell Like Burning Rubber After Driving?

While this may not be the most common cause of a burning rubber smell, it does happen. Whether you left something under the hood or picked up something while driving. A foreign object like a plastic bag can easily cause a burnt rubber smell.

Thankfully, this can be quickly resolved by opening the hood and scanning the engine compartment. If you notice something that doesn’t belong, remove it. You should also check underneath your car, and near the exhaust pipe.

Reason #7: Your Brakes Are Hot

Why Does My Car Smell Like Burning Rubber After Driving?

Most cars found on the road today feature disc brakes. Disc brakes work by squeezing pads against a rotor that is attached to your wheel, which creates friction and slows the rotation. If you have been braking aggressively, or perhaps have been driving somewhere with a lot of steep declines. It may be that your brake pads are giving off the smell, which is common and is nothing to worry about – unless it starts happening time and again.

Transmission Repair And Cost

It is also possible that one of the components in your braking system has malfunctioned, such as a caliper piston. In this case, your pads may be pressing against the rotor without you pressing the pedal.

Reason #8: The Clutch Is Going Out

Why Does My Car Smell Like Burning Rubber After Driving?

If you drive a car with a manual transmission, the smell of burning rubber may be from a burnt clutch. This is usually caused by not shifting correctly, which results in the gears grinding. If you have never experienced this, then you are either a very conservative driver – or an absolute pro.

If this happens a lot, there’s a good chance you’ll need to replace your clutch. Otherwise, you risk not being able to shift. We suggest changing your shifting strategy to something a little less extreme.
