The car may need new brakes or tires because they might be wearing down.

Squeaking can be heard on any vehicle new or not. But sometimes when a car squeaks the brakes are bad or going bad. Other times the brakes may be new, like on a new car and sometimes old ones, the brand of brake pads may be bad. When you get your brakes replaced, they are suppose to add some grease that comes in the brake package. There is a small thing on the brake pads that will squeak and rub and make noise when the pads get low. That way you will know it is time to change them, if you let it get that far. Other causes of squeaks could be shocks. If they go bad, your car can squeak and creek. You can check if your car is parked and brakes are on. Turn off your car too. Then go to the front of the car and mash up and down on the front of the car or back of car. If the car bounces freely, then your shocks are bad or going bad. Other squeaks can be drive belts loose or too tight. There are a number of things that can cause a car to squeak. Listen from where the sound is coming from. Is it in front, back, left side, right side? Is it a long squeal or squeak squeak squeak? Do it happen when you first go and stop? All this can help you or your mechanic pinpoint the source of the squeak. Remember, just because a part is new, that does not mean it is good. That goes for any product, especially electrical stuff, that is why most places will not accept returns on electrical product, coz they go bad lost of times. A squeak under acceleration could also be a universal joint going bad.
Loose alignment is the most likely culprit. It could also be the servo if your car has got one.
did you put high quality brakes on your car if so then it is normal do not worry about it. even if not some brakes just squeak all the time
car can be started an does run fine.
Generally new pads will contain a layer of dust which causes the initial squealing. The squeal should go away after a bit if driving.
