2024 Mazda CX-90: sudden loss of power

Filed Sep 2, 2026 · Brakes, Electrical · GA

Our 2024 Mazda CX-90 has experienced the same significant malfunction on two separate occasions while being driven on busy public roads. The vehicle displayed an “Acceleration Limited Due to Battery Condition” warning and experienced significantly reduced/limited acceleration while driving. This put the occupants and other motorists at risk because the vehicle could not accelerate normally in traffic. A similar occurrence while merging, crossing an intersection, or traveling in heavy traffic could potentially result in a collision. The vehicle has been taken to an authorized Mazda dealership twice for the same issue and has been out of service for approximately six cumulative weeks. The vehicle is currently at the authorized Mazda dealership and is available for inspection. The dealership has been made aware of and is attempting to diagnose/repair the recurring condition. The exact component or system responsible for the failure is currently UNKNOWN. The issue recurred after the vehicle was previously returned to us following the first repair attempt. Prior to/during the failure, the vehicle displayed the warning message “Acceleration Limited Due to Battery Condition.” Any additional warning lamps, diagnostic codes, or underlying component failures are currently UNKNOWN and are being investigated by the Mazda dealership. Additionally, while our 2024 CX-90 was at the dealership, we were provided a separate 2026 Mazda CX-90 as a loaner vehicle. While that vehicle was being driven on a main public road, it suddenly lost all power. The steering wheel and pedals became locked or unresponsive, leaving the driver unable to normally control the vehicle while it was in traffic. Fortunately, a collision did not occur. The 2026 vehicle was returned to the Mazda dealership and is available for inspection. The exact cause of that failure is currently UNKNOWN. Experiencing safety-related failures while driving two separate Mazda CX-90 vehicles has raised serious concerns rega

I am reporting a recurring safety-related issue with my 2024 Mazda CX-90 Turbo S Premium involving the mild hybrid system. The first failure occurred at approximately 28,000 miles. While driving, the vehicle displayed multiple warning messages, including "Mild Hybrid Battery Malfunction," "i-Stop Malfunction," and "Engine Malfunction." Shortly afterward, the vehicle entered a reduced-power (limp mode) condition. The loss of normal power made it difficult to safely accelerate and keep pace with surrounding traffic, creating a significant safety concern. The dealership diagnosed the vehicle and replaced the mild hybrid battery. My vehicle remained out of service for approximately one month while repairs were completed. At approximately 56,000–58,000 miles, the same problem occurred again. The vehicle once again displayed the "Mild Hybrid Battery Malfunction," "i-Stop Malfunction," and "Engine Malfunction" warning messages and again entered reduced-power mode while driving. The repeated loss of power created another serious safety concern because the vehicle could not accelerate normally when merging into traffic or driving on higher-speed roads. After diagnosing the second failure, the dealership informed me that, in addition to replacing the mild hybrid battery, corrosion had been found in the wiring harness and internal wiring associated with the hybrid battery system. Those components also required replacement. Due to parts availability, my vehicle remained at the dealership for an extended period before repairs could be completed. This vehicle has experienced the same hybrid system failure twice within approximately 58,000 miles, despite the first battery having already been replaced. I am concerned that this is a recurring defect affecting the mild hybrid electrical system. A failure that causes multiple system malfunction warnings and forces the vehicle into reduced-power mode while driving increases the risk of a crash, especially when merging onto highways

While my wife was driving my 2024 Mazda CX90 gas turbo at the posted speed limit, this vehicle suddenly without warning the car lost most of its power. She was able to move the vehicle to safety by pushing the gas pedal to the floor and achieved a maximum speed of 10 mph. The car was towed to the dealer Koch 33 of Easton, PA. The dealer diagnosed the problem as a throttle body issue. This is the second incident whereby this vehicle lost power in a similar manner but for a different reason (fuel pump) and had to be towed to the same dealer. I filed a complaint with your agency about 18 months ago. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The authorized dealer, Cochran Mazda, previously bypassed the vehicle’s hybrid system and returned the vehicle to us stating it was safe to operate and that we could disregard warning messages until a replacement hybrid battery became available. Prior to this, we had reported repeated drivability concerns, including jerking during operation. We were advised that this behavior was normal for hybrid vehicles. While awaiting a follow-up service appointment, the vehicle displayed a “Critical Engine Malfunction” warning and experienced a significant loss of power while traveling across the Liberty Bridge in Pittsburgh, PA. The vehicle would not accelerate beyond approximately 15 mph and then stalled out on the bridge. We activated hazard lights and were able to proceed slowly to a nearby parking lot, where the vehicle required towing. This incident created a hazardous traffic condition and raised significant safety concerns.

I can only best describe it as there were choppy and dead spots in my steering. Coming out of a turn, it feels like a brief loss of power steering which in a turn at highway speeds caused me to reach as I was losing control of the vehicle. Thankfully, no accident caused. I took to Mazda dealership and they confirmed my findings which included me doing a ride along with one of their chief mechanics. They kept the vehicle and later confirmed steering rack was bad and would have to be replaced after they consulted with Mazda corporate. Vehicle was just outside of warranty mileage and Mazda refused to fix as warranty repair. The vehicle had previously had the recall completed on the steering unit that included replacing a spring inside the worm gear. In my talks with Mazda dealership, they confirmed that steering racks were on back order and that the part had a superseding part number. It seemed very clear to me that Mazda new they had a problem and was not being forthright. Additionally, my conversations with their so called Customer Experience Center showed them to be evasive, dodging and unwilling to discuss the issue nor fix at their cost.

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.

While driving (less than 2000 miles on the OD) in our 2024 cx90 SE the vehicle started to shift out of timing and everything shut off at once. The vehicle lost all power and all parts shut down. The vehicle would start back up and power steering went out. Our driving speed was at 30mph so it was extremely scary during rush hour traffic. We had to have it towed to the dealership, we're not sure what the issue will be.

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.

On 12/5/2023, upon turn after intersection, loss of power to the engine. Pushing gas provided no response from the engine. Engine power cut to about 10 miles an hour. Felt as the car was driving on battery - as no engine was heard. Was able to pull over to the side. Turned off and on engine 2-3 times but the power wasn't restored. Received warning on dashboard that there is malfunction with engine. Also received errors on Mazda application I had on phone. Engine light was on the dashboard. Photos attached. While obtaining assistance for tow service I was accidentally disconnected. I tried turning the car on again, and engine turned on normally. Total time between last unsuccessful turning on/off engine was about 10-15 minutes. First time experience such issue with loss of power and engine cutting off/ not working. Informed the car dealership and car repair/ check was scheduled to be brought to dealership for 12/8/2023. Estimated repairs taking 4 to 5 days before I can get the car back. Distance to dealership about 150 miles. Confidence in this car severely shaken - considering the price and the fact it is brand new.
