Why is it that my brand new car has a burning smell and tapping noise in the engine?

It's very concerning to hear that your brand new car has a burning smell and a tapping noise in the engine. This is definitely not normal and you should take it to the dealership immediately.

Here are some possible reasons for these issues:

* Oil Leak: A burning smell could indicate an oil leak, potentially causing the engine to overheat and the tapping noise to be a symptom of damaged components.

* Loose or Damaged Parts: A tapping noise could be due to a loose or damaged component in the engine. This can happen during manufacturing or during transportation.

* Manufacturing Defect: In rare cases, your car may have a manufacturing defect leading to the burning smell and tapping noise.

Here's what you should do:

1. Stop Driving Immediately: Do not drive your car with these issues. It could lead to further damage.

2. Contact the Dealership: Call the dealership where you bought the car and explain the situation. They should take this seriously and schedule a service appointment immediately.

3. Do Not Attempt to Fix It Yourself: Trying to fix these issues yourself could make the problem worse and void your warranty.

Remember: You have a warranty on your brand new car, and the dealership should be responsible for diagnosing and fixing these problems. Don't hesitate to insist on a thorough inspection and repair.
