I'll never understand why people keep writing off this paint defect as normal wear and tear. Mazda has acknowledged this issue, and has began replacing hoods for many customers (including myself). After my hood was replaced, I no longer received a new chip every week. In fact, I haven't received any paint chips since it was replaced.
For those who keep bringing up the color matching concern, it's a baseless concern. The body shop matched the color perfectly on my car. Body shops do this on a daily basis anytime are car is in a accident.
This issue has been discussed in depth on this thread.

You're definitely not alone on this. Contact Mazda customer service (not a dealership) and give them details on how many chips you have, and when they started appearing. Best of luck!
