The Infotainment system malfunctions. The rear view camera freezes, not with the current conditions but a still picture of a street I do not recognize. This puts not only myself at risk for an accident but those of others as well. This malfunction has been taken into the dealership on two different occasions. Each time the dealer couldn't solve the issue. There is currently a class action lawsuit regarding the Infotainment system.

Twice had low oil warning lamp appear. First time in July 2023, 2nd time in June 2024. Both times oil has just been changed 2-3 months prior. Saw articles that there was a recent lawsuit, which is why I am filling complaint as well. Not for lawsuit, but for repairs so this does not occur again.

My car displayed a low oil level light between oil changes and after checking the dipstick it was low. No sign of visible oil leak so upon further research I was made aware of a TSB about defective valve seals causing excessive oil consumption. My cars VIN is in the affected range outlined in the TSB. Now when I drive it's likely that slow but permanent damage could be occuring in my vehicle.

The contact owns a 2021 Mazda Mazda6. The contact stated that the oil light continually illuminated on the instrument panel while driving at various speeds. The contact had taken the vehicle to the dealer where he was informed that the vehicle was consuming an excessive amount of oil. Upon investigation, the contact discovered information that a defective valve in the engine might have been the cause of the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 11,800.
