 Had the car for about two months now. I reviewed all the comments here about engine noise. My family drives the car most of the time and they don't pay careful attention to weird sounds. The only comment I have now is the louder engine noise after cold start in the morning which gets better after about 1 minute. I sent an e-mail to Mazda about it but no response. My dealers response was " bring the car in we will check it out" . The problem is when I take it to the dealer it will not be cold start situation anymore. I will have to take the car out for a drive more often to listen to engine noise during normal use which others are claiming. Other than that everything seems to be okay so far.
