Example complaints

“It seems like the computer has defaulted to receive the lowest possible gas mileage- if this is somehow communicating with the fuel system- its definitely affecting how much mileage I could be getting and robbing me of up to 100 miles per tank.”
NHTSA complaint #11703823, filed 2025-12“I have noticed over 30 things wrong with this car. Including but not limited to- the FIRST THINGS I mentioned to the dealership there seems to be apull to the right (suspension/alignment). The car randomly starts driving or feeling 'jerky as if cruise control has taken over - 'phantom braking' is a term I came across that sounds accurate to me. And now, after having the vehicle for almost 30 days- there is significantly less mpg.received. 300 first tank vs about 250 this current tank.”
NHTSA complaint #11703129, filed 2025-12“Car is forecasted to get 290 miles off a full tank after doing nothing but highway driving. 10 miles less than when I first drove it (off the lot and primary highway driving) and 60 miles less than it should according to Mazda statement of 21-30mpg.”
