Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Iactive sensor indicated there was a/n (obstruction) or something preventing iactive from working (i dont remember what it said)? I dont remember- but either way- i find it distracting. It could not be turned off and was flashing repeatedly- telling me to drive safely ironically making me feel like I had to read it, in inclement weather, and take my eyes off the road.”
NHTSA complaint #11703141, filed 2025-12“I have been having repeated issues with the doors not autolocking, liftgate functionality, rear seat sensor, and random (collision?) warnings/sensors - among other settings that keep coming undone (audio options, etc) since the purchase of this car that I have been diligently notating/timestamping- i have close to 200 occurences so far. Just submitting another report to let you know it is STILL happening and IS NOT user error.”
NHTSA complaint #11714353, filed 2026-01“The vehicle has major electrical issues. The ABS and all over driver safety options would shut off for days at a time. I had purchased this cx30 as new on January 02, 2026. It totally died and wouldn't start on February 03, 2026. It had to ve towed by mazda roadside assistance to Towne Mazda dealer in Orchard Park NY. It is now March 12, 2026 and the dealer has had my vehicle for over a month. They put a new wiring harness in it ans other components. Very frustrating.”
NHTSA complaint #11723758, filed 2026-03“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“The vehicle has a built in wireless phone charger. When the charger is used for for more than > 10 minutes, the phone proceeds to heat up to the point it burns your hand when you take it off the charger. I have spoken to the dealer and the service advisor says this is “normal” and occurs in a variety of car models. Then he blamed my phone, but my phone does not heat when using any other wireless or plug in charger. I am concerned that the excess heat will result in the battery exploding as we have seen with other phone charger and laptop charger devices. …”
