Service Brakes 6 Read
I purchased this Mazda new in October 2025. Since purchasing the vehicle, it has unexpectedly applied the brakes on three separate occasions while I was driving under normal conditions. There was no reason for the vehicle to brake, and each incident created a dangerous situation because the vehicle slowed suddenly…
The brakes make noise. I asked Mazda if there were any recall. The service person replied there is on the brakes but they were doing it in groups and it was not my group yet
So, if the car is on electric and I press on break, sometimes breaks feels like it's delayed to response. The car will switch to gas after it and the break will work. This happened to me in the 2024 and 2025 CX90 PHEV version. I had that issue multiple times

Istop engine malfunction Msp66, 2nd time occurring after recall fix
The vehicle repeatedly displays warnings including “Acceleration Limited Due to Low Fuel and/or Battery Condition,” Hybrid System Malfunction, and Engine System warnings. These events result in reduced acceleration and loss of power while driving. The condition occurs despite normal fuel levels and routine driving…
Early December I was driving and attempting to make a left-hand turn across traffic. I press the gas slowly in preparation to cross traffic. Once a car passed I pressed the gas to get across the traffic lanes before other cars got to me and when I pressed the gas, the car completely stopped moving. I sat there,…

Hybrid battery recall was replaced and failed a month later for a second time burning other systems and causing a compete failure in the car. It failed in a deserted portion of [XXX] while traveling from [XXX] to [XXX] for important business. This left me stranded in the middle of the [XXX] desert late at night in a…
The vehicle utilizes I-Stop, which comes on when stopping and while traveling down the interstate when the computer isn’t registering throttle input as a way to increase fuel economy. At least a dozen times now, the vehicle has failed to register throttle input, which isn't allowing the vehicle to restart when…

Immediately, we received a variety of warnings, including: "charging system malfunction", "i-ACTIVESENSE Partially Disabled", "Hybrid System Malfunction", "i-stop Malfunction", "Charging System Malfunction", and "Critical Systems Failure". Vehicle has only 20,040…
Power Train 3 Read
My car is literally stalling out on me. It started by sputtering when I put my foot on the gas a week or so ago. Then today It literally started just losing power while driving. It’s not throwing any codes but that’s super dangerous and this car is only a year old. I am extremely concerned for my safety
I own a 2026 Mazda CX-90 hybrid with approximately 13,000 miles. The vehicle began making a grinding noise while driving, which has progressively worsened over time. It has since developed a hard knocking noise accompanied by noticeable vibration when the vehicle shifts gears. This knocking occurs during normal…
ISSUE 1 – UNINTENDED DECELERATION (Power Train): While driving at highway speeds (60–80 mph) with foot off accelerator for approximately 5+ seconds while coasting, the vehicle unexpectedly executes a sharp, single downshift causing sudden unintended deceleration and an RPM spike. No warning lights illuminate.…
Steering 3 Read
The steering seems to be malfunctioning and is hesitant or sticking when operating the vehicle. The steering wheel seems to hesitate or stick only during left hand turns, even slight ones. If you do not manually pull the steering wheel back after turning, it will stay in the position and not return as it should. This…
Brakes have been really squeaky and seems like a common problem for other CX90 but no fix. Steering tends to feel “sticky” when doing certain turns and locks when you’re at the max radius and won’t return back
Every time I drive the vehicle, it basically snatches me back into the lane aggressively. If I am moving into the next lane, the lane correction is so aggressively, I am afraid it is going to cause a collision. The brakes squeak and squeal constantly. They have oiled the brakes but it didn't work
Fuel/propulsion System 2 Read
Recently, while driving our Mazda CX-90 (2025) we noticed a persistent and constant odor of fuel/gasoline vapors arise from the vehicle. We noticed this after driving the vehicle approximately 120 min from Las Vegas, NV to St. George, UT. The smell was intoxicating and nauseating. I took it into 2 local dealerships to…
I stopped for gas and when I removed the gas cap air came of out of the filler pipe like it was under high pressure. I could not fuel the vehicle because of the force of the air coming out of the tank blew gas out and shut off the pump. I started and shut off the car numerous times without the gas cap on and with it…

I purchased a new 2025 Mazda CX-90 Plug-In Hybrid, which currently has approximately 16,500 miles. Despite normal daily driving, proper maintenance, and all scheduled services performed at authorized Mazda dealerships, all four original tires have prematurely worn out and require full replacement. This level of tire…
CX-90 years to avoid — and the clean ones
Complaints per model year. More reports usually means more cars on the road as well as more trouble, so read the crash and fire columns alongside the count.
| Model year | Complaints | Top system | Crashes | Fires |
|---|---|---|---|---|
| 2025 | Electrical System | 1 | — |
The same model year, different builds
Every complaint carries the first 11 characters of the VIN — plant, year, body and engine. That is a production series, and complaints are spread across them very unevenly.
| Measure | Value |
|---|---|
| Distinct production series | 29 |
| Average complaints per series | 1.2 |
| Worst single series | 2 complaints |
| Average age at failure | 0.7 years |
A model average of 1.2 hides a worst series at 2. Enter a VIN above to see the numbers for that exact build instead of the model as a whole.

How we count
Every figure here comes from complaints owners filed with NHTSA — 1,115,966 of them, covering 2,019 models built between 1981 and 2026.
A complaint is an unverified report: someone wrote down what happened to their car. It is not a confirmed defect and not a recall. What makes the volume useful is the pattern — when thousands of owners of the same build describe the same failure, that is a signal no marketing brochure will give you.
Two things we do that the source does not. First, we compute the age of the car at the moment of failure from the incident date and the model year. Second, we group complaints by the first 11 characters of the VIN — the production series — so a bad plant run does not disappear into a model-wide average.
