Engine 46 Read
I wondered if, after my first service visit on 11-12-25, the dealership put regular leaded gas instead of premium in it, because there was a noticeable difference in gas mileage and the engine started revving pretty high, in my opinion. It also seemed to have less power (which was my main reason foe thinking the wrong…

On April 15th, 2025, my 2022 Mazda CX-30 experienced a sudden malfunction while I was driving. Despite having the automatic emergency braking system and forward collision warning, the car failed to slow down or alert me before I hit another vehicle during a pile-up. Right after the collision, my dashboard lit up with…
The vehicle has a built in wireless phone charger. When the charger is used for for more than > 10 minutes, the phone proceeds to heat up to the point it burns your hand when you take it off the charger. I have spoken to the dealer and the service advisor says this is “normal” and occurs in a variety of car models.…

Mazda is claiming that my…

While driving normally at highway speed on I-880 South, the braking system failed to decelerate the vehicle.

When the cruise control is canceled and the speed has dropped more than a couple of MPH when it re-engages the accelerator goes full throttle just like you've mashed the pedal to the floor.

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 | 158 |
| Average complaints per series | 1.5 |
| Worst single series | 15 complaints |
| Average age at failure | 1.6 years |
A model average of 1.5 hides a worst series at 15. 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 — 1,100,006 of them, covering 1,982 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.
