I doubt if there's any way to return the car for a refund or replacement unless the dealer is a really nice guy. (OK, you can return it. The dealer will be happy to keep your money and sell it again.) Many dealers will give a 30-day, 1,000 mile warrantee on the drive train, which might cover the bumping noise, depending on what it is.
If the whistling noise is coming from under the hood its your belt, that's what's wrong with my Sequoia. If its not coming from under the hood its probably a crack in the seem of your window.
We would need to know where the noise was coming from and under what conditions it made the noise in order to make an assessment.
you have a small cat stuck under your car
The lifters are failing and need replaced to stop the noise.
Not enough info. What kind of noise? Coming from where? Under what situation(s) does it occur?
This happened to me and one of my rear shocks was completely broke causing it to bump under my truck.
Where is the noise coming from? Under then hood, or interior?
A broken strut will cause a bumping sound when the wheel hits a pothole or bump. It will also make the same sound if the wheel spins under hard acceleration.
I have an after market fuel pump on my van the you can hear from inside and outside.
Transfer case pump grinding a hole through the casing, U-Joints, bearings.
it is the fuel pump because it is located in gas tank normal sound
Could you revise the question to let us know where the sound is coming from? Under the hood, under the car, from the exhaust, etc? That info would help in the diagnosis-from-afar.
