When I Accelerate My Car Makes A Humming Noise

If your car is making a humming noise when you accelerate it could be indicative of a few different issues. It could be something as simple as a loose heat shield or something more serious like a problem with your transmission.

If you have a loose heat shield it’s usually not something to worry about and can be easily fixed. However if the problem is with your transmission it’s important to take your car to a mechanic to have it checked out. Transmission problems can be expensive to fix so it’s better to catch them early.

If you’re not sure what the problem is it’s always best to take your car to a mechanic to have it checked out. They will be able to diagnose the problem and let you know what needs to be done to fix it.
