2025 Mazda CX-90 PLUG-IN Hybrid

After driving >2000 miles or about a month, I could hear a loud, grunting/grinding noise when accelerating aggressively from 1st to 2nd gear when on EV or gas mode. Brought the vehicle at the dealership service department 4 times already, each time MAZDA Headquarters in California confirmed that this is a known and documented condition. According to Mazda, the grunt noise you’re hearing when the vehicle shifts from first to second gear under medium to aggressive throttle is considered normal operation. It has been determined that this does not affect the drivability or reliability of the vehicle, and it is safe to drive. The transmission is operating as designed and performing within normal parameters. Mazda is continuing to collect data on this condition as part of their ongoing commitment to improvement. However, I totally disagreed to their answer and that the truth is that they don't know how to fix it, unless tearing down completely the transmission to find out what the cause is! I feel it is a safety problem as explained by a top transmission repair shop: "In most cases, a loud, grunting or grinding noise when accelerating from 1st to 2nd gear would likely be considered a defect that substantially impairs the vehicle's use and could also affect safety, particularly under the context of Oregon's Lemon Law. Here's why: •Impact on Use: Grinding and grunting noises suggest that the transmission is not functioning properly, according to Top Notch Transmissions. This makes the vehicle less reliable and less enjoyable to drive. If the problem persists or worsens, it can hinder the vehicle's ability to operate safely and effectively, potentially leading to hard or delayed shifting, or even transmission failure."

The contact owns a 2025 Mazda CX-90 PHEV. The contact stated that the hybrid battery failed to charge above 80 percent, and the "Engine Malfunction" warning light remained illuminated. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 25.

Vehicle had the dreaded 3 code battery malfunction. Charging system malfunction, critical vehicle malfunction (electrical leakage), & hybrid system malfunction. Making the car unable to drive and have to get towed. The car had me pull over at which point it could not be turned back on. It could not even be put into neutral and had to be pulled onto a flatbed truck. I bought the car on Dec 27th and Dec 28th it was broke down with 126 miles on it. It’s now Feb 22nd and they don’t know how to fix the car. This seems to be happening to many of these cars.
