MAZDA 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.

Safety concerns of Sam Leman Mazda located in blooomington IL installed a radiator from auto zone instead of using Mazda-approved parts. Sam Lemans modified other vehicle components to make the auto zone part fit and initially suggested using zip ties. My vehicle was held from Nov 5-25, 2025 while the dealership attempted to figure out how to alter components to fit the Auto Zone part - my choices were use the (1) Auto Zone part or (2) supply my own. Mazda corporate was then involved due to the unnecessary vehicle modifications due to Sam Lemans using a non approved Mazda part (Auto Zone radiator). Sam Leman compromised safety & my vehicle has been compromised due to component alternations and non Mazda approved parts. The auto zone part was not designed for my specific car and could fail during normal driving conditions. By altering the fan housing to make the unauthorized Mazda part fit, Sam Lemans created a risk of mechanical failure or accident. I am have a video showing the dealership discussing “zip tie” repair to hold the weight of the radiator (but this site will not allow me to upload a .mov video for your review only a photo of the video is there an alternate email I can send the video for review of Sam Leman’s mechanic discussing using zip ties to)? I am requesting NHTSA review this as a safety risk due to the wrong part, alteration of other parts, and non mazda approved part used by an authorized Mazda dealership, even after Mazda corporate was notified.

[XXX]: while entering La Crescent, MN from [XXX] southbound, the right side BSM mirror warning illuminated with NO vehicle in blind spot.

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.

Dash button for lift gate not working. Occasionally the doors dont autolock Both of these things have happened multiple times since I drove the car off the lot .

Headlight humming / headlight unit failure. Known issue with Mazda but they refuse to repair unless I pay $2k for a new headlight. Vehicle has less than 50k miles and this is a know issue for 2019-2023 CX5s.

The contact rented a 2024 Mazda CX-30. The contact stated that while driving at highway speeds, an "i-ACTIVSENSE Partially Disabled Front Radar Malfunction" warning message appeared on the instrument panel. The contact attempted to exit the highway; however, the vehicle failed to stop upon depression of the brake pedal. The contact continued to pump the brakes and even engaged the emergency brakes, but the vehicle failed to stop. Due to the failure, the contact crashed into the vehicle in front of her as the "Vehicle System Malfunction, Have the Vehicle Inspected" warning message appeared on the instrument panel. The air bags did not deploy upon impact. The contact later sought medical attention for pain in her back; the other driver sustained injuries; however, the injuries are unknown as she did not seek medical attention from the paramedics that arrived at the scene. A police report was filed. The vehicle was towed from the scene to an independent mechanic, where it remained in their possession. Neither the dealer nor the manufacturer had yet been notified of the failure. The vehicle was not repaired. The failure mileage was 38.377.

Although im confident in my own driving skills, it concerns me that the blind spots are so bad that it is NECESSARY to use the blind spot warning system and reverse/back up camera.

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.

Warning sensors activate randomly- of oncoming vehicles- in my opinion for no reason. Enough space between cars. Normal speeds, etc. Warning sensor to engage Brakes activate without sufficient reason. More than enough space between cars, normal speeds. Occasionally, it feels as if cruise control has taken over and slows the car down (not braking exactly, but controlling the speed by decreasing it). Acceleration also seems to randomly be controlled in the same manner.
