Istop engine malfunction Msp66, 2nd time occurring after recall fix
I am submitting this complaint regarding my 2025 Mazda CX-90 PHEV, leased in April 2025. Since early in my lease, the vehicle has had ongoing drivability issues that have worsened over time and now present a serious safety concern.From the beginning, the vehicle exhibited jerking and hesitation while 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,…

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.…
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…
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
Service Brakes 3 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 car automatically brakes at lower speeds. This happens about 3x week and typically on a specific freeway entrances but in other locations as well. I believe this is a known phantom braking issue but for some reason my car is not included in the recall
I am writing to formally express my dissatisfaction and concern regarding my recently purchased 2025 Mazda CX-90. I purchased the vehicle on February 15, 2025, and it currently has approximately 1,100 miles on it. Since acquiring the vehicle, I have experienced a persistent and extremely loud squeaking noise from the…

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…
2025 backup camera not working with 8,500 miles on the car. This is a safety hazard and so far neither Mazda of Everett who broke it will not fix it unless I pay just about 1,300. They claim I have to talk to Mazda to see if they will warranty the part even though I have a 4 year 48,000 mile bumper to bumper warranty.…

Vehicle has only 20,040…
Steering 2 Read
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
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
Seat Belts 1 Read
Seatbelt got stuck between seat and seat frame. Seatbelt was stuck in the locked position and was neither able to be retracted or pulled out rendering the seatbelt unusable. This is a huge safety concern as we were stranded at night with small children and unable to use the seatbelt. A recall should be made to this…

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…

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 | 22 |
| 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 — 1,109,349 of them, covering 2,013 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.
