the noise you are reffering to I believe is the ABS check.

Yes, it is a diagnostic check that the ABS does to ensure all of the solenoids are reacting properly. It is slightly more noticeable on ECO models because they have less sound insulation than my LTZ, but I do not find it intrusive. This check usually occurs at about 10 mph.

If the ABS system does not like the results of the chek your ABS light will come on alerting you to a problem. It is not a defect at all, it is your Cruze making sure you are safe and ABS enabled.
