2025 MAZDA CX-70

ELECTRICAL SYSTEM:BODY CONTROL MODULE:SOFTWARE

Mazda North American Operations (Mazda) is recalling certain 2024-2025 CX-90 and 2025 CX-70 mild hybrid electric vehicles (MHEV). The fuel gauge in the instrument cluster may display an inaccurate fuel reading.

Risk: An inaccurate fuel gauge may result in the vehicle unexpectedly running out of fuel and stalling, increasing the risk of a crash.

ELECTRICAL SYSTEM:SOFTWARE

Mazda North American Operations (Mazda) is recalling certain 2024 CX-90 and 2025 CX-70 plug-in hybrid electric vehicles. Improper inverter software may cause the malfunction indicator lights to illuminate, and a loss of drive power may occur while in electric vehicle (EV) mode.

Risk: Loss of drive power increases the risk of a crash.

ELECTRICAL SYSTEM:SOFTWARE

Mazda North American Operations (Mazda) is recalling certain 2024-2025 CX-90 and 2025 CX-70 vehicles equipped with a Dash Electrical Supply Unit (ESU). During vehicle startup, the defroster, seat belt warning, 360° view monitor functions, and the PHEV high-voltage battery cooling system may not function properly.

Risk: An ESU that does not function properly, increases the risk of a crash.

LANE DEPARTURE: WARNING

While traveling eastbound on GA-20, I signaled to change lanes with my hands in the 9 and 3 position. I don't hold the wheel in a death grip like some people do, as I am confident with my vehicle and my skills. As I am changing lanes at 62 mph the car jerked the wheel to the right while flashing a warning that I need to hold the wheel. This has happened multiple times even though I am in complete control of the vehicle and very comfortable with my hand position. The car should NEVER jerk the wheel like that unexpectedly. I have lane departure turned off for this reason.

FUEL/PROPULSION SYSTEM

CX-70 routinely has been falsely alerting to an impending crash when no vehicles in front or to the sides. Vehicle routinely does not alert when there is traffic to left or right when merging into a lane. Multiple near accidents when a vehicle was present in blind spot when merging lanes and the safety system failed to steer away or make an alert noise. Vehicle routinely alerts to take over steering wheel even when both hands are on steering wheel. I do not feel confident in the safety systems as they are not executing safety procedures as described in the vehicle manual and appear to be defective. Vehicle fuel gauge consistently under reports the amount of remaining fuel. This causes the gauge cluster to fall to empty faster than it actually should be.

POWER TRAIN

After starting the vehicle and driving it for a short distance, I forgot to disable the engine start/stop function. When the engine shut down, I pressed the button to disable it as I loathe this feature. The button would not respond, resulting in the engine repeatedly shutting down during coasting events and limiting the functionality of my AC. I tried multiple times during my 45-minute drive to disable it, but was unable to. I shut the vehicle off and restarted it when I was safely stopped. The system worked as intended after this action. I have never had a car with so many technology bugs and electronic safety system issues as this one.

LANE DEPARTURE: WARNING

While attempting to change lanes on I-75 southbound, one lane to the left of my current position, I was enforced and the steering wheel pulled back to the right. I was navigating a right-hand curve on the interstate and moving past slower traffic at 81 mph. My turn signal was activated, the lane departure system deactivated, and the signal was still flashing as the lane change was executed. The turn signal should suspend enforcement as well as the system being deactivated. Both interlocks failed to operate. No other vehicles in the area would've contributed to this event. The lane departure "off" warning light was on the dash, indicating that the system was not operational. I was not firmly holding the wheel and allowing it to glide effortlessly through the lane change to execute my plan when it jerked back to the right.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

I was operating the motor vehicle at roughly 60 mph on a two-lane divided highway around 830AM. I was driving toward the sunrise to the east and passed under a highway overpass. As I cleared the overpass from the shade back into the sun, the vehicle flashed a collision warning on the windshield and immediately applied aggressive braking for no reason. No other cars were in the area around me at the time of the incident. Had someone been following me too closely, this would have likely resulted in a rear-end collision. Safety system malfunctions are frequent and unexpected. It is always something, and this isn't the only time it has happened. It has simply annoyed me enough to cause me to submit a report.

LANE DEPARTURE: BLIND SPOT DETECTION

On multiple occasions I have had driver assistance system failures with the most recent occurring this past Saturday 8/2/25, which I have on dashcam. In this incident, I had adaptive cruise control set to short following distance. I had about 5 or 6 car lengths in front of me at highway speed and the lead car was far enough ahead that the car was not showing it on the interactive display. Another car changed lanes from the right to left in front of me right behind the lead vehicle. The car that changed lanes was not detected by the vehicle even though it was right in front of me. I was approaching the vehicle at a higher rate of speed and the car never attempted to slow eventually requiring me to depress the brake to cancel the cruise as the car was not responding to the fact that I was now right behind the car and had to brake to avoid a collision. On a separate incident a month or so ago, I was entering a center turn lane, waiting to turn into a gas station which required crossing of 2 lanes of traffic in the opposite direction. As I was entering the center lane with my signal on, the car detected the opposing traffic and slammed on the breaks nearly causing me to get rear-ended by the traffic behind me that expected me to enter the turn lane at the rate of speed I was going. Routinely, the car fails to detect vehicles in the blind spot. I can approach, pass, and clear a vehicle on the left (vehicle to my right) and the car will never detect that a car was there in the first place. Additionally, if a car is detected and then stays in the blind spot long enough, the car loses it and thinks the car is no longer in the blind spot.

Blind spot monitoring at highway speeds randomly triggers when nothing is there. Due to this, car fights lane changes due to collision avoidance system if you try to change lanes when it thinks something is there when it’s not.

Plastic trim pieces emblems are melting. Dealer replaced the first two trim pieces and said they would not cover remaining pieces if they melted. I feel all the plastic parts are melting on this vehicle and it is a 2025. This should not be happening. What can be done? First piece was window pillar trim drivers side on May 14, 2025 and the second piece was the In-Line 6 emblem front panel drivers side July 3, 2025. Each time outside temperature was 90 degrees. Inferior plastic melting should not be the consumers responsibility to repair.

SEAT BELTS

As I was stopped on [XXX] waiting to turn left onto [XXX] , another vehicle struck mine from the rear, at approximately 50mph. The seat belt did not immediately lock, compromising my safety. I slid upward, partially out of the seat belt striking my head on the headliner and the belt caused a large bruise on my upper left arm. Additionally, the air bags did not deploy, but a spray of chemical came out onto me from the dash. The chemical sprayed onto the right side of my neck and collar bone, leaving a burning sensation. A week after this wreck, all the skin that was contacted by the spray, began peeling off, like a sunburn peel does. After this wreck, a warning notice appeared on my dash screen, stating AIRBAG FAILURE, in red lettering. There were no failure notices prior to this wreck. It’s unknown if any inspection of these two failures was done by my insurance adjusters, the manufacturer, the police or a dealership. There has been no known reproduction of these failures I am aware of. The vehicle is expected to be a total loss, but I am still waiting for that determination. The vehicle is still at the repair facility, Caliber Collision in Carbondale, IL, as of 7-1-2025. I have reported these failures to my insurance representative, the manufacturer, the repair facility and the dealership.

POWER TRAIN

This has been happening for over 6 months but it's getting worse. When moving at a lower speed, 10-20 mph, the motor or transmission is jerky and sluggish. This makes it very slow to move when pulling out from red lights or when in stop and go traffic on the highway. (Might as well be pulling out from the light in an 18 Wheeler.) I haven't taken to the dealer because from my experience, unless there is a code to look up, it's just money (and time) wasted. No, the vehicle has not been inspected by the manufacturer, police, insurance representatives or others. No warning or messages have been displayed, no other symptoms to report. One more thing, after driving for hours and getting back to the office. With the vehicle in Park, the rear passenger removes their seat belt and the driver removes their seat belt, the seat belt warning message displays. Now I could understand this if the vehicle was placed in Drive or reverse, but in Park? Really? Also note, in the mornings, the vehicle can sit and idle for over an hour and if the rear passenger doesn't have their seat on and you put it into Drive nothing happens, no messages or warnings at all. What if you had a kid in the back seat or something? Make it make sense.

SERVICE BRAKES

Vehicle has been squealing countlessly when braking about 1 to 2 days after leaving the dealership in September 2024 up until current. The vehicle has been out of commission for more than 15 days while attempts to repair the issue at local Mazda dealerships. On the last attempt to correct the issue, Ferman Mazda dealership in Brandon FL performed some sort of shaving of brake component to ensure this would not continue; however, the noise continues and this also may increase the safety risk now.

My auto flashed an Engine Malfunction error then lost power. I had to pull over immediately. Would not restart. Unsafe road with no shoulder in a no passing two lane road. Towed to dealer. They told me gas tank sensors failed. Resolution is a new gas tank. This could have been much worse had there been a car behind me, had children in car, been on a highway etc. The auto did not show any signs of issue until the warning light that appeared as the auto lost power. The auto is at the dealership where it will remain until new part comes in. I was told there has been an influx of this part being requested and it could be 2 months before one is available. Very dangerous. Mazda road side assistance sent tow truck.all communication with dealer has been via phone except for text letting me know the auto arrived there.

LANE DEPARTURE: BLIND SPOT DETECTION

The i-Active safety sense system in the vehicle shuts off in moderate rain. I believe it to be far too sensitive. the system complains that it cannot see the road and vehicles with the camera system. Inclement weather is when I need the i-Active safety sense the more. Earlier this week on my way to work, it disabled itself in very light rainy conditions. I had no trouble seeing but the system did. When this happens cruise control is completely disabled. I reported this to the dealer but they shrugged their shoulders. No one seems to test these systems in less than perfect weather. There are warning on the dash saying that i-Active safety sense is disabled.
