2024 Mazda CX-90- Plug-in Hybrid power train problems

“Vehicle alarming charging system malfunction. Vehicle lagging and lurching forward. Unable to drive safely. Battery lights on. Second time this has happened. Currently at dealership for repair.”

“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…”

“I bought my 2024 Mazda CX-90 PHEV 10 months ago with 22000 miles on it and no and now has 29000 miles on it. First thing I had a issue with was a Motor Mount was bad, took 12 weeks to get part was told it was safe to drive. Next, since I have had the vehicle I have been having a issue with the transmission making a noise while both shifting from first to second and also on down shifting. It does not happen all the time but is happening. I took the vehicle in to the dealership to have it looked at and they were able to reproduce the issue. When they conferred with Mazda on the issue they were told that it was a known issue but there is no fix for it at this point and was dertermined safe to drive. I also talked to Mazda myself who also told me that it was a known issue but there is no fix and determined it safe to drive. I love the vehicle but to have this noise keep happening and being told they are working on a fix does not make me feel confident in the vehicle with this especially when my wife also drives it. My biggest question is this is a 2024 Mazda and I am told the 2025 also has the same problem. How long is the answer were working on a fix to long to…”

“During normal operation of the car the radiator sprung a leak which could have resulted in leaving us stranded with our young kid. this was verified by the dealership who's only solution has been to replace the radiator at our expense. There were no warning lights or other indications of the damage other than coolant leaking from the bottom of the car”

“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…”

“When curving left my steering wheel will get “stuck”. It becomes heavy and then jerks back like it just “unlocked”. I haven’t had to pull it back forcefully, yet, but I’m sure it’s not far off. Went to Mazda dealership who state it’s mechanically related to a rack and pinion within the steering components. My car was part of the initial “sticky steering” recall which the previous owner had done in March of 2024. Happy to allow inspection if needed. My safety, along with the safety of others, is at risk anytime I travel along a curve where I could cross into on coming traffic because I am unable to forcefully move my steering wheel out of the “sticking” position. Potentially deadly. Mainly notice it around speeds of 45+ regardless of weather.”
