ABS....Again~~

[MeggiemobileSFLA]

Please, anyone out there with a Yaris sedan that has power package with ABS. I need to know if you have a specific noise that is heard only the when first turning the car on and putting it into gear and then hitting the gas(in that seqeunce). Only when you hit the gas does it do it and it only happens once. The only way to recreate the noise is turning it off and doing it all over again. Mine has done it since the first day i bought it and i keep being told that its my ABS resetting or being initiated. Since the yaris doesnt have alot of sound insulation is supposedly the reason why i hear the noise. The dealer people are nice but i just dont buy the fact that my car should make a noise.... It's pretty inconsistent in the severity of the noise, meaning sometimes it's louder than other times. Since its so inconsistent, that makes me think that its something else, possibly serious to the point where i may be hurting the car by driving and making it make that noise. I would really appreciate any response from anyone who has the sedan with ABS... My next step is to visit another dealership to possibly test drive a sedan with ABS to compare....The dealership i bought it from keeps jerking me around and i have been there 5 times in a month, which is when i bought it....HELP
