STEERING

Mazda issued a recall on the steering column which was done a year ago. The steering wheel continues to stick when turning on an intermittent basis requiring extra force to bring the wheel back to center. It’s been happening for a while and the service dept told me it was the tires. I replaced the tires and it continues to happen. Mainly happens when driving around turns towards the left and driving around 30-50mph. It occasionally happens when changing lanes on the highway.

Issue Summary: Since December 27, 2024, my vehicle has experienced a hybrid malfunction and leakage issue three times. Each time this occurs, the vehicle becomes completely inoperable and cannot move, requiring a tow truck to take it to the dealership. Since December 27, 2024, my car has been in the shop four times, yet the issue persists. This raises serious reliability and safety concerns, as the vehicle can suddenly become unusa

FUEL/PROPULSION SYSTEM

Received Hybrid Battery Malfunction and Electrical Leakage Detection alerts two weeks ago. Dealer has not been able to fix. First they said it was the water heater, then they said my radiator was leaking and I need a new one. Estimated 4 additional weeks for repair.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

The vehicle does not slow down or reduce speed until the brake pedal is pressed at least 1/5 of the way down when using cruise control. The brake light turns on, but the car continues to accelerate.

LANE DEPARTURE: BLIND SPOT DETECTION

Blind spot monitors alert for things like light fog. I cannot trust a system that thinks water vapor is going to be an issue while turning or merging.

The seatbelt reminder system is broken and someone almost took my door off this morning because I had to open my door to get it to stop. Every day when I drop my kids off at school I have to make sure the vehicle is in park so the seatbelt reminder doesn't go off. If they open it a second before I put the vehicle in park it will keep beeping and beeping until I turn the car off, open my door, and turn the car on. I had to do that today and at a stop sign. It's busy by the school so everyone is in a hurry. So it was beeping non stop because my son unbuckled early and the car will keep beeping even if noone is in the seat. I stopped at the stop sign, turned off the car (and it still kept beeping), opened my door to get it to stop, It was at this point the person behind me thought my car was disabled and went around me, almost taking out my door and possibly my arm at the moment. I also have to do this when someone in the back seat moves seats (and we have to put a seatbelt on an empty seat) or even puts some pressure on a seat. If they sit inbetween seats we then have to put a seatbelt on an empty seat. Dealer says this is the way its designed.

This is a 2024 Mazda CX-90 PEHV where I took it in for all recalls on January 17th, 2025 related to loss of power and hybrid system malfunction.

I am submitted this report for the 12/6/2024 event. The form I submitted previously was for the safety incident that occured last night (1/9/2025). On four different occasions, the most recent being last night (1/9/2025), the vehicle has suddenly lost drive power while driving. The ability to accelerate is suddenly gone. When you press the gas pedal the engine revs, as if it is in neutral, but it does not accelerate. When this happens, the vehicle is still in drive as indicated by light on the shifter showing drive and the fact the vehicle, just moments before, is driving. During all four instances, I had to bring the vehicle to a complete, put the car in park and then back into drive. On three of these occasions there was no pull-out lane and I had to bring the vehicle to a complete stop in a moving lane of traffic. The incident last night occurred mere seconds after making a left-hand turn with traffic coming up behind me at a higher speed then I was travelling. My safety, the safety all passengers in my car and the safety of other drivers are all at risk when this occurs. When this happens there are no warning lamps or messages that appear. After the third time it happened (on 12/6/2024), we took the vehicle to the Mazda dealership we leased it from and it was inspected and we were told they found nothing wrong with it. They noted they did some updates. They kept the vehicle from Monday 12/9 - Thursday 12/12. Less than a month after getting the vehicle back from the dealership this issue occurred a 4th time (on 1/9/2025 at about 8pm). We will be calling the dealership this morning and setting up an appointment for them to again inspect the vehicle for this safety concern. The vehicle is available for inspection.
