ELECTRICAL SYSTEM

2 complaints

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.

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. Perhaps they honestly do not realize this is an is an issue, but do we have to wait until someone is seriously hurt before it is addressed?

Had this Mazda CX30 as a rental car for about a week. Was pulling into the driveway, hit the brakes, and the vehicle took off full speed causing a crash. The engine was revving at max and the vehicle was accelerating as if the gas pedal was floored. No matter what pedal I hit the car just kept going until the crash and being shut off.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER,FUEL/PROPULSION SYSTEM

1 complaint

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.

UNKNOWN OR OTHER,FUEL/PROPULSION SYSTEM

1 complaint

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.

TIRES

1 complaint

At an unspecified service visit I Was told tires were at manufacturers recommended psi YESTERDAY - left the lot at 1530. The next morning - warning system indicated low psi- even as low as 30psi and front passenger so low it did not give a reading??? I have no idea why a service visit was even recommended at 1000 miles. Intake rep said for manufacturer oil change and maintenance?! 1000 miles? Bought 11-8-25?! So, if service visits are directly tied to software communication of the vehicle then, thats being reported too.

ENGINE

1 complaint

I wondered if, after my first service visit on 11-12-25, the dealership put regular leaded gas instead of premium in it, because there was a noticeable difference in gas mileage and the engine started revving pretty high, in my opinion. It also seemed to have less power (which was my main reason foe thinking the wrong gas had been out in). And since then, it hasn't been the same.

VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE

1 complaint

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.

VISIBILITY/WIPER,LANE DEPARTURE

1 complaint

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.

STEERING,FUEL/PROPULSION SYSTEM,VISIBILITY/WIPER

1 complaint

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.
