Most Common Problems

When analyzing the complaints lodged with the National Highway Traffic Safety Administration (NHTSA), it becomes evident that certain issues stand out as the most common problems reported by 2021 Mazda CX-30 owners. Among these complaints, engine problems, electrical system issues, and forward collision avoidance problems take the top spots. Additionally, visibility and wiper complaints, steering issues, and vehicle speed control problems also made the list.

Engine Problems

Engine-related issues have been a significant concern for 2021 Mazda CX-30 owners, with several complaints highlighting various aspects of engine performance. One common complaint category within engine problems is oil consumption. Some owners have reported unexplained low engine oil levels, raising concerns about potential engine damage and lifespan. Mazda has acknowledged the issue by issuing a technical service bulletin (TSB), but the root cause remains elusive. As a result, affected owners are advised to visit their dealerships whenever they experience this problem.

Apart from oil consumption, other engine-related complaints include battery issues and network malfunctions. Some owners have experienced in-vehicle network malfunctions, leading to warning messages about auto light and power steering malfunctions. In another case, a CX-30 owner faced warning lights and a failure to start, which required battery replacement. It’s crucial to address these engine problems promptly to avoid any further complications and protect the longevity of the vehicle.

Forward Collision Avoidance Issues

Forward collision avoidance problems have also been reported by several 2021 Mazda CX-30 owners, highlighting concerns about the effectiveness of the system. Among these complaints, unexpected automatic braking incidents have raised safety concerns. In some instances, the automatic braking system engaged even when there were no obstacles in front of the vehicle. While the exact cause of these incidents remains unclear, one owner mentioned the presence of black flies on a sensor as a potential trigger. Further investigation is necessary to determine the root cause and address this issue effectively.

Visibility/Wiper Problems

Two complaints related to visibility and wiper problems have surfaced among 2021 Mazda CX-30 owners, both directly linked to issues with the windshield. These complaints revolve around distorted and warped windshields, leading to impaired visibility. Owners have reported that the glass distortion is a well-known issue discussed on various Mazda forums. It’s essential for Mazda to address this problem promptly to ensure the safety and satisfaction of CX-30 owners.
