“Fuel filler line leak. When gas tank is full fuel leaks from small whole in line that goes into gas tank. My mechanic says it is where the line is welded to gas tank has broken the Mazda service manager tells me it's not an issue that Mazda will fix, even though it is a safety issue. My mechanic says that this is an issue with the 2013 models, so if the same thing happens to a 2012 model why it not be repaired by maxda?”
NHTSA complaint #11164272, filed 2018-12, 81,800 miles“I just got off work and got in my car to leave. I turned on the car and everything seemed normal.

NHTSA complaint #10778627, filed 2015-09, 28,625 miles“I was driving my 2012 Mazda 3 skyactiv and a couple spiders came out of nowhere almost causing me to crash. I know, stupid.

NHTSA complaint #11101564, filed 2018-06, 98,000 miles“I was driving slowly in traffic when I noticed a large white spider about the size of my thumb come out of the dashboard (where the mpg display is located). The following morning, I noticed another spider on my dashboard near the vent at the very front. Both spiders looked exactly like the white sac spiders described in the Mazda 6 recall.
