STEERING
Approximately six weeks ago, I began to notice the steering locking up ever so slightly as I made corrections in sweeping turns at 50 mph or so. In the beginning, I thought that it was road imperfections, but then it became more persistent and undeniable. Following this, it began to lock up more so when turning from a standing stop and accelerating, as when I was merging into traffic from my subdivision street. Some days, I notice it more than others. I was unnerved. I took the vehicle to the dealer, reported the concern, and was regarded as a purple squirrel. I was told that every update related to the steering had been completed and that there was nothing that they could or would do. The problem remained. With the concern remaining, I returned to the dealer and was told that someone else with the exact vehicle reported the problem the day before. Still, there was nothing that they could do as Mazda had not provided any guidance. I do not want to drive the vehicle. It is unsafe.

UNKNOWN OR OTHER, SEATS, STEERING
Mazda's Driver Personalization System is highly defective and properly recognizes a driver, at best, 40% of the time. Since multiple functions are tied to this system such as seat position, steering wheel position, infotainment presets, and a variety of other vehicle preferences, this not only causes an inconvenience issue but also a safety issue. The safety problem is that one has to stop the car, put it into Park, press through multiple menus and keystrokes just to change the setting to the correct driver.

UNKNOWN OR OTHER
Mazda Connect (Infotainment System) will regularly freeze and reboot. Issue is more pronounced when more than one iPhone is connected via USB-C. If each phone has a different version of iOS, Mazda Connect will freeze, crash, and reboot. If one person is connected and then physically disconnects, then another iPhone with a different version of iOS connects, Mazda Connect will freeze, crash and reboot. To make matters worse, these incidents are not recorded in any logs.

ENGINE, ELECTRICAL SYSTEM, POWER TRAIN
Stopped at a red light on a busy 2-lane road. I-stop function turned the engine off. When the light turned green, releasing the brake caused a "Hybrid Battery Malfunction" error and the engine failed to start. We put the transmission in park and attempted to turn off and turn on the car with the push to start button. When we attempted to start the car with the push to start button, the car would not start. We were unable to shift into neutral to move the car out of the busy 2-lane highway and were blocking traffic for about an hour. The first tow truck to arrive was unable to move the car onto the flat-bed because the transmission was stuck in park and would not go into neutral so another tow truck was dispatched with a dolly. Our safety was at risk because we were stuck in an immobile car in busy highway traffic. A police officer arrived to help direct traffic around our disabled car. The vehicle is currently at the dealership and has not been inspected as of the time of this report.

ELECTRICAL SYSTEM, ENGINE
Mazda CX 90 PHEV. When charging on 110 standard outlet or 240v dedicated breaker - Chargepoint charger, the car onboard charger/inverter backfeeds a loud buzzing / humming back through the electrical wire to the electrical panel. It also causes a buzzing/humming in other appliances and causes led lights in the house to flicker. This is with a 100amp breaker panel and a new upgraded 200amp breaker panel. May cause electrical issues up to electrical fire in other areas of the home. Scheduled diagnostic test in vehicle 10/1/24, but other owners report same issue on Mazda CX 90 online forums.

VEHICLE SPEED CONTROL, STRUCTURE:BODY, FORWARD COLLISION AVOIDANCE: WARNINGS
I was parking the car at a low speed (2mph) when it suddenly accelerated with a great speed, jumped the curb in front and moved forward and up a small hill. The car collided with a tree before I was able to stop it. All ADAS features were activated in the car and no alarms sounded prior or during the event, which lasted between 1-2 seconds. The vehicle was inspected by Mazda and deemed safe to continue to operate. The dealer did not find a cause for the malfunction and suggested external influence. The inspection took about 3hrs, which included addressing multiple recalls on the vehicle. At time of incident I have owned the car for about two months and did not experience similar issues, however others did according to my web search. I found reports on popular forums describing sudden acceleration of Mazda CX-90 vehicles.

VEHICLE SPEED CONTROL, UNKNOWN OR OTHER, POWER TRAIN
I was driving in EV mode and was behind another vehicle waiting to turn out of a plaza. The exit is on a slope which is important to mention. The car in front of me began to turn and as I was releasing the brake to move up the hill, the car engine kicked on, the RPM’s went up extremely high as if the accelerator was being pressed all the way to the floor, the car jolted forward on its own and hit the car in front of me. I kept trying to brake, but the car continued to accelerate on its own into the car in front of me a second time. I understand that when on a slope driving in EV mode, the cars engine will kick in to allow the car enough momentum to make it up the hill. However, in this case, the engine kicked in, but the momentum was extreme to the point that when I released the brake to roll forward the car shot forward so fast there was no avoiding a collision. This is extremely faulty and unsafe! My child and I suffered injuries as a result of striking the other car twice. We’re lucky we were not hit by multiple other cars as we were propelled into the intersection. I’m terrified to drive this car with my children. I contacted the dealership that instructed me to have the collision repairs completed first and then they would check out the car out.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Driving between 30 - 40 mph on a strait road with no obstacles in front or along side the emergency braking engaged for no apparent reason at all! This has been an ongoing issue with this vehicle, there was a recall to update the software but the problem still exists intermittently! This is a very serious safety concern to have an all of a sudden unexpected hard braking action when the road is free and clear!

VISIBILITY/WIPER
I took delivery of this car about a month ago from the dealership in Kansas. On my way home to Grand Rapids, Michigan I noticed that the driver side rear view mirror was vibrating severely to the point that the image in the rear-view mirror is blurred. This is during daytime driving, at nighttime this issue severely impacts safe driving as I am unable to locate the type of vehicle accurately. Mazda seems to be aware of this issue since 2023 and have been trying to address it through TSB's indicating the dealers to replace the mirror glass. I have taken my car to my local Mazda dealer in grand rapids Michigan, and they have performed the latest TSB on the car, but the mirror continues to vibrate although less than before but still presenting a safety risk while driving. Per the latest conversation with the dealership, Mazda is still continuing to fix a better fix for this issue and I am asked to keep checking each month.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Mazda Radar Cruise Control - while on [XXX] and passing a truck that is in the right-hand lane, especially on curves, my CX-90 PHEV system brakes, but there is no vehicle in front of me. It has difficulty determining what is in front as opposed to on the side, especially through curves. This happened more than once. I almost got rear-ended due to this issue.

ELECTRICAL SYSTEM
The contact owns a 2024 Mazda CX-90. The contact stated that on several occasions while driving at various speeds, the message "Vehicle Failure Detected - Hybrid System Malfunction", "Possibility of Restricted Power Output", "I-Activsense System Malfunction", "Dynamic Stability Control Malfunction", and "Push button Start System Malfunction" were displayed. Additionally, the I-Activsense warning light was illuminated. The vehicle was taken to a dealer where it was diagnosed that an unknown software needed to be updated. The vehicle was repaired but the failure reoccurred. The vehicle was taken back to the same dealer where it was diagnosed that the connector to the battery needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 3,960.

FUEL/PROPULSION SYSTEM
I was traveling at 40mph on August 14 when the engine stopped running suddenly and without warning. I lost all power. I tried pressing the gas pedal and the engine shuddered and sputtered with the speed ranging from 0 mph to about 18mph with no steady duration longer than a second or two. At the same time an engine icon appeared and a message displayed reading engine malfunction. I safely exited the travel lane despite having very little power. I waited 10 seconds and restarted the car and everything worked fine. I called the dealer explained the incident and to made arrangements to have the vehicle serviced. The appointment was for Friday. When I asked whether I should continue driving the car. I was told that so long as the engine icon was not flashing the car was ok to drive. The next day I started the car and did not see any warning message or engine icon. I thought all was ok so I cancelled the appointment. A second incident occurred later in the morning. I called the dealer again and was told to bring the car in that afternoon, Thursday. On the way over to drop off the car a third incident occurred with the same characteristics as the first two. Each time waiting 5 to 10 seconds restored power to the car. One week later the car was returned to me with the diagnosis of low fuel pump pressure problem. I am wary of driving this car on any trip especially on a speed highway for fear this situation will occur when I am driving at 70mph. I appreciate your taking the time to read this description of a very scary and unnerving situation that no one should face.

Cars behavior – Air conditioning motor running but not cooling air, Loss of power and car very sluggish (have to be careful at intersections), seems to maintain speed even when taking foot of gas and requires extra breaking, seems to be clunky when transmission upshifts/downshifts at times. When leaving work, did not seem to like being in EV mode even though fully charged (Chargers at work) and would switch itself out of that move and say unavailable. Outside air temperature 90 degree (Air Conditioning not working, very uncomfortable). This defect is dangerous and I serious concerns driving this car such as unpredictable loss of power when entering traffic and hesitation / unpredictability when hitting the accelerator. In addition, with the car maintain speed while not touching the gas pedal and requiring extra breaking is a scary. June 13 – Issue cleared and wanting lights were gone before I was able to take it in for service. July 25th – Recurrence of the same issue - Odometer – 8,162, Gas – Full, Electric – 14 Miles range - From work to Home, Receive the following errors “Engine Malfunction, Have Vehicle Inspected” and “Hybrid System Malfunction, Have Vehicle Inspected” warning lights come on.

ENGINE, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
On July 15, 2024 this vehicle at 50 mph on cruise control suddenly flashed white warning words indicating problems with the cruise control and immediately thereafter started flashing “hybrid malfunction” and to return to service dealer. At the time of the hybrid malfunction warning which was right after the quick cruise control warning, the engine operation, specifically the gas pedal no longer delivered power to vehicle, either electric or gas. Additional warning was to pull off to the side and stop and turn off vehicle. This occurred and vehicle was pulled to the side put into park and turned off. Waited approximately 3 to 5 minutes and restarted the engine which started in gas with no electric although there was electrical charge on the battery. Was able to continue to our final destination approximately 15 minutes later and no more than 10 miles driven. Hybrid malfunction was still visible on the dash to include the warning stating that vehicle needed to go to the service department. Approximately an hour later, vehicle was turned on again with the same warning about the hybrid malfunction, however, engine started in electric. Drove vehicle to dealership and stated what happened. Dealership the next day stated that this was a phantom code known by Mazda, but no problems associated with the code. Vehicle picked up per service advisors request two days later. Mazda dealership stated that headquarters had eyes on this particular vehicle. A day later after the pick up Mazda dealership requested vehicle be brought back for a “DC box” repair. Dealership stated this process would take a week or thereabouts to replace this component. Vehicle currently in dealership service.

VISIBILITY/WIPER, VISIBILITY:REARVIEW MIRRORS/DEVICES:EXTERIOR
The driver's side mirror vibrates excessively when traveling on the highway or at higher speeds (50+ mph). This has been present ever since taking delivery of the new vehicle on [XXX] and poses a safety risk as it compromises visibility to adjacent traffic. The problem was confirmed by the dealer on [XXX] and repaired according to manufacturer TSB 09-018/24. However, the problem continued to persist after the repair. The defect was reported again on [XXX] and the dealership claimed that they contacted the manufacturer where no additional fix was available. The defect was reported yet again for a third time on [XXX], at which time the dealer still claimed that there was no updated fix.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Going down the road with cruise control I have been used to it dropping a little bit in curves but today and car behind me had to slam on there brakes because the cruise control in a small curve dropped me down immediately from 60 to 45 jerk and all. If the driver behind me had not been paying attention they would have slammed into me since we were both going 60 no other cars around just a small curve on a straight road
