   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…

   Driving down the freeway, the car throws an error code, reduces speed from 75 to 40 in seconds, with enough time to pull off the freeway. The car has an error code stating "Hybrid battery malfunction." Now the car will not start. The Dealer could not get it started and now wants to charge me for a diagnostic. But from my understanding, they should cover a new battery under EPA regulations (40 CFR Part 85). Any help would be greatly appreciated.

I sat praying for 45 minutes while we waited for a tow truck. Cars were flying past us as we were blocking 2 lanes of traffic, one of which was…
