started shaking, and could not make it up hills at a safe speed. The check engine light came on. We pulled over and popped the hood to find a lot of rat feces scattered all over the engine bay, some of it looked fresh and some was turning white telling us it was there for a while. We called the Hertz rental roadside assistance who could not help us as they rented out all of their cars for the weekend and our only options were to tow us back to [[redacted]] without a replacement car or try to continue driving it the 1 hour to our destination. We continued to drive the car as we did not have anywhere else to stay and were in the middle of nowhere. We drove the car slowly to our destination but it did keep making the noise and shaking although the check engine light went out. When I got out of the car, I noticed a raw gas oder which worried me. I called my dad who works on cars and he told me not to drive it any farther as it could be a serious safety risk as the rats likely have been chewing wires and hoses and there could be a fire risk. We were also breathing the rat feces in our whole trip unknowingly. We called for the car to be towed and paid to rent another from another company. Since then, we have not gotten any money back and they continue to charge us daily for the car saying we must return it, meaning they have no record of where there car is even though we watched it be towed away and talked to the driver who said he was taking it to the Grand Junction Airport.

and knocking. The dealer stated they are aware other customers have reported the same issue, but that Mazda considers the noise/knocking acceptable and declined to perform a repair. No warning lights or diagnostic trouble codes have appeared at any point; the only symptoms are audible and physical. The vehicle is under both factory warranty and a purchased service/maintenance agreement. It has only been inspected by the selling dealership; no inspection has been performed directly by Mazda North America, law enforcement, or an insurance representative. I am concerned about my safety and the safety of others because a worsening, unexplained drivetrain issue that produces hard knocking and vibration during routine driving suggests a mechanical fault that could progress to sudden failure, and the manufacturer has declined to investigate or repair it further despite the symptom escalating across two documented visits. The vehicle remains available for inspection upon request.

merging or at intersections.Approximately six months into my lease, the radiator failed and had to be replaced. More recently, while driving, multiple warnings appeared at once: Hybrid System Malfunction, Battery System Malfunction, Oil Monitoring Malfunction, and i-ACTIVSENSE partially disabled. These warnings were documented.Two weeks prior, the dealership reported no diagnostic codes. However, on my most recent visit, I was told via video that the active air shutter is now the issue. The required part is on backorder until August. I was told I could either remain in a non-comparable loaner while still making full lease payments, or continue driving the vehicle in its current condition until the part arrives. I find this unacceptable given the safety concerns.I expressed that I do not feel safe driving this vehicle, but the service advisor stated this is "not a safety concern." I disagree. A vehicle that jerks, hesitates, or stalls while driving, combined with multiple system malfunctions and disabled safety features, presents a clear safety risk.I also disclosed prior to leasing that I do not have access to charging. I was told this would not be an issue. I am now being told that not charging the vehicle may be contributing to the problem. Service advisors have also indicated these vehicles have known hybrid battery issues.I no longer feel safe driving this vehicle and am concerned for my safety and my family's safety.

this dealer since they were involved in addressing the recall about "fuel sensors". An email was also sent to Mazda corporate so they would be aware of the response we received from the dealer and help with a car rental. It was very fortunate that we were not on the highway when this happened as it would have been an extreme safety risk.

point, I had cars stopping & honking at me because I was sitting in the middle of oncoming traffic, unable to move my vehicle. Then (12/15) I was sitting at a stop sign, waiting to turn right. I made my right turn advancing onto the new street and my car stopped moving entirely and started flashing two errors, both hybrid system malfunction and engine malfunction. I tried to get the car moving for a bit, switching gears, pressing brake then gas, etc. After putting the car in park & turning on flashers (I was blocking a lane of traffic) and powering the car off and then back on again the car moved, however, the errors are still there.I called the dealership & brought the car in. After a diagnostic they cleared the code & told me to go. I told them it was not safe to put my children in the vehicle and they needed to identify the root cause and fix the problem.

unresolved. This creates an unsafe driving condition due to unpredictable power limitation. This issue appears to be a known problem affecting Mazda CX-90 vehicles and may be related to hybrid system software or battery management. The vehicle was being driven on a city road (Lake Forrest and University dr in McKinney, TX). Turned right off of a shopping center exit toward Lake Forest Dr. The vehicle lost power all of a sudden and would not accelerate with traffic heading in my direction. The vehicle signaled to stop and place the gear into park. I was able to slowly change lanes and pull into the Chipotle parking lot at 5151 W. University Dr at 10:56 am. I called Mazda Roadside and they came to tow it to El Dorado Mazda dealership. This incident: Date: 01/10/26 Time: 10:56 am Temp: 45° / clear and sunny Previous Incident: 12/04/25 6 pm Parked - Idling at Prosper High School. I-stop and hybrid system malfunction warnings appeared Called El Dorado Mazda- advised it was not a safety issue and sometimes it just needed a software update or the battery was bad. They scheduled a service appt until 12/17/26 due to lack of loaner vehicles available. 12/08/25 / 12:05 pm Clear weather Inspected at El Dorado Mazda Could not be Duplicated. Battery OK Nothing came up on diagnostic machine. Cleared recall. Advised to return if it happened again. Reassured me it was safe to drive and I was not in danger. 12/16/25 Car started from park at home Approx 40-50° 9-10 am 1/10/26-
