Owners of the 2024 Mazda CX-90 frequently report issues with the powertrain, particularly involving hybrid system malfunctions and sudden loss of power. Symptoms include unexpected deceleration, inability to accelerate, and the vehicle becoming immobile, often accompanied by warning lights such as "Hybrid Malfunction" and "Engine Malfunction". These issues are reported at various mileages, with some occurring as early as 3,200 miles. Safety implications are notable, with two crashes reported, including one involving injuries, and multiple instances where vehicles stalled in traffic, posing a risk of collision. Buyers should be aware of these recurring problems, especially concerning the hybrid system and its impact on vehicle control.

Owners report that the 2024 Mazda CX-90 frequently experiences engine malfunction warnings and issues with the cooling system, including coolant leaks and engine overheating. Complaints often mention symptoms such as loss of engine power, hesitation during acceleration, and unexpected transitions between hybrid and gas modes. These issues typically appear at low mileages, with some reports occurring as early as 2,000 to 5,000 miles. Safety implications are noted, with several owners describing incidents of sudden power loss on highways, raising concerns about potential risks while driving. Buyers should be aware of these recurring issues and consider the potential for unresolved problems even after recall-related services.

Owners report frequent issues with the 2024 Mazda CX-90's adaptive cruise control, particularly when driving near large trucks or on curved roads. Complaints commonly describe the vehicle braking suddenly and unexpectedly, often when passing or approaching trucks, leading to potential rear-end collision risks. Additionally, several owners mention incidents where the vehicle accelerates or decelerates without driver input, with some reports noting these events at highway speeds, around 5,000 miles. Safety implications are significant, with multiple accounts of near-misses and concerns about being rear-ended. These patterns suggest potential challenges for buyers considering this model, especially those who frequently use cruise control features.

Owners report frequent issues with the driver-side mirror on the 2024 Mazda CX-90, specifically noting severe vibration at speeds typically over 40 mph. This vibration causes blurred vision in the mirror, making it difficult to accurately judge the distance and type of vehicles behind, particularly during highway driving. Complaints indicate that this problem is acknowledged by dealerships and seems to be a known issue by Mazda, yet no definitive fix is currently available. The passenger-side mirror is generally unaffected, and the issue is often observed from the first days of vehicle ownership. The safety implications include potential difficulty in lane changes and assessing traffic, which could lead to hazardous driving conditions.

Owners report several issues with the 2024 Mazda CX-90's braking system, including loud squealing at low speeds and instances where the brakes fail to engage. Complaints frequently mention dashboard warnings such as "Engine Malfunction" and "Hybrid System Malfunction" accompanying these brake issues, suggesting potential interactions with other systems. Notably, one report involves a crash resulting in injuries, where the brakes did not respond, and another describes sudden uncommanded braking while passing a truck. These issues occur at various mileages, with one specific case at 23,209 miles. Safety implications are significant, as some incidents involve loss of control or potential for collision, which prospective buyers should consider.

Owners report several issues with the fuel and propulsion system of the 2024 Mazda CX-90. Complaints frequently mention sudden loss of power while driving, with some instances occurring at highway speeds, posing potential safety risks. One owner describes a diagnosis of low fuel pump pressure, while others note propulsion loss in EV mode and a "Hybrid System Malfunction" warning even after a recall service. Another issue includes the gas door becoming stuck. These problems appear sporadically, with no specific mileage or timeline emerging from the complaints. Potential buyers should be aware of these reported issues, especially regarding sudden power loss that could impact driving safety.

Owners of the 2024 Mazda CX-90 report several structural issues, with the most frequent being defective rear door seals that allow water and dust to enter the vehicle. Additionally, some owners describe incidents involving the rear lift gate unexpectedly closing without warning, causing physical harm in one instance. Complaints also include reports of sudden unintended acceleration while parking, resulting in a crash, though the cause remains undetermined after inspection. Another issue involves the driver's side mirror vibrating excessively, impairing visibility. These problems are noted in vehicles owned for a short period, suggesting they may appear early in the vehicle's lifespan. Safety implications are significant, given the reported injury and crash associated with these structural components.
