AIR BAGS

6 complaintsSafety-related

Owners of the 2024 Mazda CX-30 report issues with airbag deployment, with some experiencing unexpected deployment without prior warning or alerts, even at low mileages around 4,000 miles. Complaints frequently mention problems with airbag warning systems, such as indications that passenger airbags are not engaged, despite attempts to recalibrate. One incident involving a crash resulted in airbag deployment causing injuries, highlighting potential safety risks. Additionally, issues with water intrusion leading to rust and corrosion of airbag components are reported, particularly soon after purchase. These complaints suggest a range of airbag-related concerns that could affect safety and reliability for potential buyers.

6 complaints total1 crash2 injuries

ELECTRICAL SYSTEM

3 complaints

Owners report several electrical system issues with the 2024 Mazda CX-30. Commonly mentioned problems include failure of the infotainment system, climate controls, and braking system, as well as inconsistent operation of door locks, lane departure, and blind spot monitoring systems. Symptoms often include illuminated warning lights on the instrument panel and malfunctioning of the rearview camera and cruise control. These issues are reported at low mileages, with one owner noting problems at just 900 miles. Safety implications are suggested by the loss of control over vehicle functions, though no crashes or fires are mentioned.

3 complaints total

LANE DEPARTURE

3 complaints

Owners report that the 2024 Mazda CX-30 exhibits issues with its lane departure and related safety systems. Complaints frequently mention the vehicle's emergency braking system activating unexpectedly, often due to misinterpreting shadows or nearby vehicles as obstacles, which poses a risk of rear-end collisions. Additionally, there are reports of the vehicle incorrectly detecting nearby vehicles when signaling turns, and failures in the Forward Sensing Camera affecting multiple features such as lane assistance and automatic headlight adjustment. These issues have been noted shortly after purchase, with one owner indicating the problems were present since delivery. Safety implications include the potential for collisions due to unexpected braking, and multiple owners express difficulty in obtaining repairs, especially when their vehicle is not covered by existing recalls.

3 complaints total
UNKNOWN OR OTHER (3 complaints)

UNKNOWN OR OTHER

3 complaints

Owners of the 2024 Mazda CX-30 report issues primarily related to electronic systems and the transmission. Complaints frequently mention Apple CarPlay disconnecting mid-drive, which causes distraction and navigation loss. Additionally, a significant transmission problem is noted, with reports of loud whining and grinding noises leading to a complete transmission failure at around 20,000 miles, without any dashboard warnings. Another issue involves the keyless entry system malfunctioning, preventing the car from starting, even when using alternative key fobs, shortly after purchase. These problems present potential safety risks, particularly the transmission failure, which could result in sudden loss of propulsion while driving.

3 complaints total
FORWARD COLLISION AVOIDANCE (3 complaints)

FORWARD COLLISION AVOIDANCE

3 complaints

Owners report issues with the forward collision avoidance system in the 2024 Mazda CX-30, primarily involving unexpected braking and acceleration behaviors. Complaints frequently mention the vehicle braking abruptly during highway turns when using adaptive cruise control, with deceleration ranging from 5 to 12 mph. Another common issue involves the braking system activating erroneously when accelerating from a stop or maneuvering into parking spaces, with one owner noting this at approximately 2,500 miles. Additionally, owners describe the cruise control system as causing the vehicle to accelerate too aggressively after being canceled and re-engaged, as well as inconsistently modulating brake and gas inputs when navigating highway curves. These symptoms may lead to potential safety concerns, such as unexpected stops or loss of control, particularly in high-speed or congested traffic situations.

POWER TRAIN

1 complaint
2026-01-01

I had both the left front and right front CV axles fail. My car only has 11.5k miles on. I first heard the clunking noise at 11k miles, went right to the dealer and had them watch me recreate the noise and they determined the axles needed to be replaced. This is incredible dangerous as the CV axle could have been completely disconnected from the wheel assembly leaving my car useless and uncontrollable.

The contact rented a 2024 Mazda CX-30. The contact stated that while driving at highway speeds, an "i-ACTIVSENSE Partially Disabled Front Radar Malfunction" warning message appeared on the instrument panel. The contact attempted to exit the highway; however, the vehicle failed to stop upon depression of the brake pedal. The contact continued to pump the brakes and even engaged the emergency brakes, but the vehicle failed to stop. Due to the failure, the contact crashed into the vehicle in front of her as the "Vehicle System Malfunction, Have the Vehicle Inspected" warning message appeared on the instrument panel. The air bags did not deploy upon impact. The contact later sought medical attention for pain in her back; the other driver sustained injuries; however, the injuries are unknown as she did not seek medical attention from the paramedics that arrived at the scene. A police report was filed. The vehicle was towed from the scene to an independent mechanic, where it remained in their possession. Neither the dealer nor the manufacturer had yet been notified of the failure. The vehicle was not repaired. The failure mileage was 38.377.

2025-03-13Fire reported

I have a brand new Mazda CX-30 with less than 10k miles. I was not made aware of the seat material being highly flamible. Luckily I nor my kids were in the car when the seat caught fire due to a magnifying effect. Magnifying Effect (Sunlight): If a clear glass or plastic object (like a water bottle, eyeglasses, or even a certain type of air freshener) was left on the seat in direct sunlight, it could have acted as a lens, focusing the sun's rays onto a small area of the seat material. Over time, this concentrated heat could become intense enough to ignite the fabric, especially if it's dry and flammable. This is more likely to happen on a hot, sunny day. I brought this up with the dealership and their reply was to contact Mazda! YOU are Mazda!

How We Calculate Reliability Scores

Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.

Key Ranking Factors

1

Complaint Severity

NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.

2

Repair Costs

Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.

3

Recall Impact

Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.

4

Issue Diversity

Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.

Scores are grouped into four tiers:

  • 80–100: Excellent — Top-tier reliability, minimal issues
  • 60–79: Good — Reliable with some minor concerns
  • 40–59: Mixed — Notable issues, research before buying
  • 0–39: Risky — Significant problems, proceed with caution

Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
