Mazda cx-30 Problems

Vibration when driving at low speeds:

Some users have reported that their Mazda CX-30 vibrates when they are driving at low speeds and when they turn the steering wheel to either side.

This vibration can be caused by a few different issues, such as a faulty rear differential or a problem with your tires. Cx 30s that are affected by this problem experience vibrations when driving between 1500-1650 rpm.

Soy Based insulation:

Soy-based insulation can be found in many modern vehicles including the Mazda CX-30 where it’s used as an insulator between body panels and other components that need protection from heat or cold temperatures.

Unfortunately, soy-based insulation can develop cracks over time, which allows moisture into the vehicle’s interior through these cracks, causing mold growth and other problems, such as corrosion of electrical wiring harnesses that could lead to rats and rodents eating the wires.

Battery discharge problem:

Some users have complained about their cars not starting after sitting for long periods of time due to a battery discharge problem; electronics and other components in the vehicle may be affected by this issue.

If you experience this problem, be sure to have your battery tested and replaced if needed.

AC (Not Cold Enough):

Depending on the person, some people find that the air conditioning is not cold enough and they don’t like it. This is not a groundbreaking problem and is highly subjective but most people complain about the ac being not cold enough.

If you are one of these people, be sure to let your dealer know so they can diagnose the issue and fix it for you.

Jumpy/Jerky Transmission at low Speeds

The CX-3o may be one of the most fun cars to drive in its class. It’s quick off the line and has great handling on winding roads.

The issue lies in the transmission; it seems to have trouble shifting gears smoothly at low speeds (e.g., when parking or entering traffic). This can be irritating for some drivers but not others depending on their driving style.
