Mazda3 Lawsuit Alleges Window Stickers of Certain 2025 Vehicles Misrepresented Sound System, Radio Features
A proposed class action lawsuit alleges Mazda Motor of America has misled consumers by falsely representing on the window stickers affixed to certain 2025 Mazda3 models that the vehicles are equipped with an eight-speaker audio system and high-definition (HD) radio.

The 52-page Mazda lawsuit claims that the 2025 vehicles at issue, in fact, are equipped with only six speakers and standard radio, in contrast to what’s stated on each car’s federally mandated Monroney label, a window sticker meant to provide consumers with key information about a vehicle’s performance characteristics, engine and transmission data, environmental and safety ratings, interior specifications and other features.
The class action suit against Mazda alleges the automaker has falsely advertised the audio features of the following vehicle models:
According to the case, the sound system misrepresentations are significant given that HD radio provides additional digital features and clearer audio quality than standard radio. What’s more, an eight-speaker audio system creates a more immersive listening experience and affords consumers more control when balancing audio from front to back, the complaint explains.
The data featured on a Monroney sticker, which, by law, must be prominently displayed on the window of every new vehicle offered for sale or lease in the United States, is specifically designed to inform car shoppers’ purchasing decisions, the lawsuit stresses.
The filing contends that Mazda customers reasonably expected their vehicles to contain eight speakers and HD radio as advertised and argues that they would not have paid a premium price, or bought or leased the cars at all, had they known these features were missing.
The plaintiff, an Illinois resident who purchased a 2025 Mazda3 2.5 S Hatchback in March of this year, says he discovered the vehicle lacked HD radio and two rear speakers when he was searching through the infotainment system and attempting to alter his sound settings. The consumer claims that balancing his vehicle’s sound to the rear speakers resulted in “no sound at all” coming from the car.
The plaintiff alleges that after contacting the Mazda dealer about the missing features, he received an email from a representative admitting to the misrepresentations and acknowledging the presence of “typos” on the window sticker of his vehicle model.
Mazda has tried to conceal the issue, lawsuit asserts
The class action suit claims that Mazda, in an apparent bid to “cover up” its conduct, has quietly replaced the Monroney labels on the vehicles at issue with window stickers that no longer bear the sound system misrepresentations. Mazda also “secretly” updated the online versions of the labels in late March 2025, the case charges.
The complaint contends that although Mazda is aware that its marketing was deceptive, the company has failed to issue any recalls, reimburse customers, fix or add the advertised features when requested or take other corrective action.
