2024 MAZDA CX-90 Complaints

Braking System and Infotainment Malfunctions — 2024 Mazda CX-90 PHEV Vehicle: 2024 Mazda CX-90 PHEV Incident Dates: June 1, 2024 June 16, 2024 June 30, 2025 Ongoing (infotainment issue) Summary of Complaint: I am reporting multiple safety-related concerns with my 2024 Mazda CX-90 PHEV involving both the braking system and the infotainment/electrical system: 1. Delayed Brake Engagement – June 1, 2024: While stopping for a pedestrian crossing the street, I pressed the brake pedal and the vehicle lunged forward before the brakes fully engaged. The delay in braking caused the vehicle to move forward several inches before stopping, nearly endangering the pedestrian. It felt as if the brakes did not respond immediately when applied. 2. Sudden, Unnecessary Braking – June 16, 2024: While following a vehicle that was slowing down to make a right turn, the CX-90 PHEV abruptly and aggressively braked on its own, despite sufficient following distance and no imminent collision risk. The rapid deceleration nearly caused the vehicle behind me to rear-end us. This appeared to be triggered by the vehicle’s automated braking or forward collision system reacting too strongly. 3. Infotainment System Failure – Ongoing / June 30, 2025: The infotainment system frequently restarts itself, shutting down entirely and rebooting without warning — particularly while driving in larger cities. On June 30, 2025, the system completely failed, and a warning appeared on the dashboard stating that the vehicle needed service. After shutting down and restarting the vehicle, the message disappeared. However, this intermittent failure creates a serious distraction and potential safety hazard while driving.

Engine Malfunction have serviced. At least 3 times. One of the 3 (so called) repairs took 3 weeks. They said “Tariffs you know Japan”. When I get this warning my car engine seems to vibrate. I have only had my car since August of 2024. New vehicle I am the 1st and only owner. Today is June 22, 2025 and tomorrow will be another incident number 5. My car is doing this again. I am a [XXX]. Most of the time my car is in the garage. But I have to drive 188 miles on the turnpike to visit my son and come back. This is every 3 months or so. My other son drove to South Texas. These warnings always came on. Am I supposed to stay home and only go to the store. I pay over 700.00 a month. This is not good. I am now getting afraid to drive it. So tomorrow I will again have to drive to Edmond Oklahoma and have it repaired again. “Engine Malfunction have services”. I’m so disappointed. My son has a cx-5 and it’s a great car. I’ve had so many loaners. They have been fine. I am told this is a brand new model and we have to get the kinks out? This is at my expense, peace of mind. Please help me. Thank you.

I’ve been experiencing power loss and surges/RPMs drop for nearly a month now while driving at various speeds. Each time, the iStop indicator comes on. This is a serious safety concern. I am extremely worried that the vehicle could stall, especially while my family is in the car, while driving on a busy highway. Undoubtedly, this issue presents a significant risk to the safety of drivers and passengers. I am requesting your assistance in initiating an official recall from the manufacturer for this component failure. Based on my research, I am not the only one experiencing this grave issue. Many others have reported similar problems on forums like Reddit, which is proof that this is a widespread issue.

- Serious safety issue: car stopped suddenly in the middle of traffic - Errors appeared: Hybrid System Malfunction, “vehicle can not be driven” and “Electrical Leakage in Hybrid System Detected” - Would not come out of park, had to be towed to Mazda dealership - Picked up car and after 15 min of driving the 'hybrid malfunction' light came back on - Car was returned to Mazda dealership for testing

Mazda issued a recall on the steering column which was done a year ago. The steering wheel continues to stick when turning on an intermittent basis requiring extra force to bring the wheel back to center. It’s been happening for a while and the service dept told me it was the tires. I replaced the tires and it continues to happen. Mainly happens when driving around turns towards the left and driving around 30-50mph. It occasionally happens when changing lanes on the highway.

Brought vehicle into Dealer for Service due to Check Engine Light being on and Notification of a Malfunction of the I-Stop System. Service Tech indicates that this is a known issue with the Hybrid Battery in these vehicles that could cause the vehicle to unexpectedly stall. This safety issue is significant enough that they would not let us take our car home while we wait for them to obtain a battery, which are currently on backorder. Pursuant to a conversation with a Mazda Customer Experience Representative this has been a known issue since at least January. We have not received any correspondence from Mazda regarding this issue. It would appear that a Bulletin or Recall is warranted for what appears to be a prevalent issue with significant safety impacts.

On multiple occasions the vehicle has falsely detected collisions and suddenly braked while on highway leading to serious safety issues. On other occasions, while changing the lanes with blinkers on, the vehicle suddenly steered back into the original lane and triggered a collision warning even though there was no vehicle/obstacle nearby. This created a serious risk of collision. Even at slow speeds, the vehicle inaccurately triggers a collision warning creating unsafe driving conditions. This frequently happens when we are driving the vehicle in the parking garage, even in absence of moving vehicles nearby. The mild hybrid power train system had issue leading to hybrid system malfunction and iSTOP malfunction. This finally led to hybrid battery failure and the vehicle remaining out of service for over a month. Apple Carplay disconnects erratically creating hazardous condition especially when we are using Carplay for navigation. Such a disconnection requires the driver to suddenly reach over to the phone and input driving directions in the phone again. This is especially dangerous in city driving conditions needing frequent turns.
