This issue often occurs without warning and persists despite multiple service visits and battery replacements, primarily affecting vehicles within the first two years of ownership. Other reports include instances of the odometer rolling back unexpectedly to 9,999 miles and a sudden, loud static noise from the speaker system that cannot be turned off, both of which have been acknowledged by Mazda as occurring in other vehicles. A few owners also mention problems with key fobs leading to battery drainage.

Additionally, there are reports of the driver door failing to open from the inside, regardless of whether the engine is on or off, with one owner experiencing this issue twice in four months. These problems may pose safety risks, especially in emergency situations where quick egress is necessary. No specific mileage or timeline patterns emerge from the complaints, but the recurrence of issues suggests potential reliability concerns for prospective buyers.

Owner complaints3
SERVICE BRAKES
Owners of the 2020 Mazda CX-30 report issues with the vehicle's automatic emergency braking system engaging unexpectedly, even when no obstacles are present. This sudden braking can bring the car to a complete stop, posing a risk of rear-end collisions. One owner mentions this issue occurring 11 times, with the dealership unable to replicate the problem. Another complaint describes a delay in brake engagement while exiting a highway, along with periodic hesitation during acceleration. These issues are noted to occur within a few weeks of ownership, suggesting they may arise early in the vehicle's lifecycle. Safety implications include potential rear-end collisions due to abrupt stops.
Owner complaints2
ENGINE
Owners of the 2020 Mazda CX-30 frequently report issues with the low engine oil light activating. The symptoms described include the light appearing at random intervals, sometimes after driving for 10 to 20 minutes, while in other instances it does not appear even during longer drives. Another pattern observed is the need to add a quart of oil every 1,000 to 2,000 miles, with this issue beginning around 20,000 miles for one owner. No safety implications such as crashes, fires, or loss of control are mentioned in these complaints. This information may be useful for prospective buyers to consider potential oil consumption issues in this vehicle model.
Owner complaints2
SUSPENSION
Owners report issues with the suspension system of the 2020 Mazda CX-30, particularly with the coil springs. Complaints frequently mention rear coil springs breaking around 30,000 to 33,000 miles under normal driving conditions, with one owner specifying the break occurred in the lower middle of the coil. Symptoms include the inability to safely drive the vehicle until repairs are made, as no warnings are provided by the vehicle's safety system. Additionally, one owner notes premature wear of both front and rear brakes, with metal-on-metal contact occurring just outside the warranty period. These issues may have safety implications, as broken coil springs and compromised brakes can affect vehicle control and safety inspections.
