Engine Noise problems of the 2018 Mazda CX-5

1509 miles on my new Mazda cx 5 purchased at marin Mazda in san rafael CA. On may 22, 2018 this vehicle keeps having some kind of what feels like a wheel resistance issue. Not sure if it is something happening in the drive train or transmission. Also not sure if it has anything to do with the way the vehicle starts everyday - this car over revs itself when started first thing ticking very loudly, rattling , pinging all kinds of different noises. It is ticking so loudly because it is over revving itself and there is no oil throughout the engine yet. Even after it stops over revving after a few minutes the car continues to have excessive engine noise the service advisor at marin Mazda insists that this is normal for Mazda's to sound like this & is ok. I don't believe him. This kind of start up everyday is going to cause problems in this engine quickly and premature failure of this cars engine. Mazda dealers are concealing some defect that is causing this car to start like this. This is something that should have been disclosed to the customers before they sell this car. Because it did not sound like this when I test drove it. That is because they take you inside while the car is warmed up so you can't hear it. That is concealing this major issue from the consumer. This is Mazda's standards of doing business. Concealing known defects of their vehicles then when a customer brings the vehicle in for repair they tell them it is operating as it was intended to by the manufacture. If this is correct then these things should have been printed on the window sticker on the car not concealed and not mentioned to the customers. This is very deceptive for Mazda, it's dealers and representatives to hide and lie about the merchantability condition of this vehicle. Because nobody wants to buy a brand new car that sounds like a rattle trap ghetto sled when it is started everyday.

June 4 2018 my brand new 2018 Mazda cx 5 that I bought from marin Mazda in san rafael CA driving on freeway at approximately 68 mph my car suddenly is slowing down- like self braking on its own- I was not braking- this was happing while I was accelerating -it felt like I was towing a large tractor - this resistance keeps recurring causing safety concern as well as bad gas mileage- while this issue is happening I get between 15 -17 miles per gal. - took pictures of fuel monitoring system. Having to make my way to the nearest exit with cars honking at me was dangerous. Car had 350 miles on it. Took car back to marin Mazda a couple days later for this issue and because it is very loud with excessive engine noise when started everyday. Very concerning as to it being a new car. Dealer said that's just how Mazda's sound it's ok we didn't notice anything out of the ordinary. Your car is fine. The wheel resistance you are feeling is probably because they spray stuff on the car to prevent rust before they ship vehicle, that coating just needs to burn off. So you need to drive it to burn it off. Your car is operating the way it was intended to. Really - this is not how any new car sounds or drives. I have a passenger with me at this time he also stated this was not a normal condition for any vehicle that is operating properly.
