2025 Mazda CX-70 problems

“Within 100 days of purchasing the CX70 new ,we noticed that the collision avoidance system was malfunctioning . It would alert when no car was near us . It did not alert every time a car was actually in our right blind spot or moving through our right blind spot . The malfunctions were random and happened in a variation of conditions and driving situations . We began to mistrust the system and continually disregarded many of its alerts . The old boy who cried Wolf sinerio.We took the car into a Mazda dealer in [XXX] ,FINDLAY MAZDA they told us that the system is malfunctioning but the software fix is not yet available from the manufacturer Mazda. We were told to wait for contact from Mazda to get the update . About two moths later we backed into a mailbox at slow speed and received no alert . This collision caused $600 damage to the right tail light . This incident prompted me to call Mazda customer experience to get our software update expedited. They resisted and continued with the unavailable narrative .I insisted and demanded a fix as this was a safety feature that is now an unsafe condition and also it is a very expensive feature on this car that we paid…”

“Vehicle Information I am reporting multiple persistent safety-related defects in my 2025 Mazda CX-70 that began immediately after purchase and continue despite repeated service visits, software updates (including MSP66 on July 9, 2026), and good-faith repair attempts. These defects substantially impair the vehicle’s safety, drivability, reliability, and security. • Warning Lights & Phantom Braking: Brake messages and related warnings on the cluster appeared on the drive home from the dealership shortly after purchase, even with no obstacles present. Intermittent false warnings have continued. • Shifter / Transmission Behavior & Hard Shifting: Intermittently fails to engage Drive after Neutral (especially after car washes). The shifter moves to D but the vehicle remains in Neutral. Notable hard shifting and intermittent poor power acceleration have also been observed. Video evidence provided to dealer. • Door Lock & Latch Failures: Doors intermittently fail to lock or unlock via key fob or interior switches. Doors sometimes do not open when pulling handles. Auto-lock does not always engage. I have observed the vehicle automatically lock (audible sound and…”

“While driving at a speed just under 45 mph, my Mazda CX-70 suddenly displayed and chimed “Hybrid System Malfunction. Have Vehicle Inspected.“. This warning startled me because I am familiar with issues since I had briefly owned a CX-90 PHEV the first year this model came out and it had the same exact problem. I discovered that this issue carries serious safety concerns and ended up convincing the dealer to swap the vehicle for a CX-90 inline 6 gas only model after hours of pleading. I ended up signing up for another lease a couple of years later with this current CX-70 PHEV, as I was told that the “bugs” have pretty much been worked out so I would give it another try. This warning continued to stay on as I drove for a few minutes so I immediately took the car straight to the Mazda dealership service department where it was kept 24 hours. The dealer said that the issue resolved itself - something to do with not driving the vehicle interchangeably enough between gas and EV mode. The photo was taken once I slowed down to stop at an intersection since it took me 15 minutes to drive to the dealer.”

“The steering wheel on the car will often get stuck and not return to the normal position when turning. Happens at low speeds on on/off ramps and at interstate speeds when the road slightly shifts. “Jerking” the steering wheel is often required to get the car to drive straight and return to normal driving position.”

“On the morning of January 28, 2026 I arrived to work and came to a complete stop in my works parking garage. I used my key card to raise the gate. Once the gate was fully raised I pressed the accelerator to drive up the ramp. Shortly after accelerating, my engine revved really loud and high rate, then my car automatically increased speed. I immediately pressed the brake pedal but it didn’t stop. It continued accelerating at a speed not controlled by me with my brakes not engaging even though I was pressing the brake as hard as could. I estimate I travel about 100’ with no control of the gas or brake. It lasted about 15-20 seconds. If a car were in front of me at that time, I would have crashed into them because I could not stop the car. I immediately called Davis Moore Mazda. I had the vehicle towed there because I didn’t feel safe driving it. Information from my cars computer program was sent to Mazda. Mazda didn’t see any issues and their diagnosis was a foot was likely on the accelerator causing the acceleration. The general manager called me to discuss. He said the only thing that registered was acceleration. I asked does the computer show my attempt to…”

“The contact owns a 2025 Mazda CX-70. The contact stated that while attempting to stop at a stop sign, the vehicle shut off unintendedly. The engine malfunction warning light was illuminated. The vehicle was towed to the dealer, where it was diagnosed and determined that the battery needed to be replaced. The contact had asked about the failure two times. The vehicle was repaired twice for the same failure. The manufacturer was not notified of the failure. The approximate failure mileage was 38,000.”
