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.

Vehicle displays low engine oil light about every 1,000 miles due to burning oil from faulty valve stem seals from factory assembly. Mazda has acknowledged the defect but plans to only refill engine oil. The defect could lead to possible injury due to low oil which could cause the engine to seize and cause sudden loss of power.

The engine oil low light has illuminated multiple times. I verified that there is no external engine oil leak. I have added oil and driven it for a couple thousand miles and the light is now on again. The car is brand new and should not be burning oil. Its a known issue as Mazda has a service bulletin but no fix for it. This is the bulletin number TSB-01-012/21.

Excessive oil consumption. Recently purchased new vehicle with 0 miles. Oil low level warning light on at 3500 miles. Manually checked oil level. Added one quart. Online research indicates problem is created by faulty valve guide seals which allows oil into the engine combustion chamber and exhaust. Vehicle will be taken to dealership for inspection.

The low oil pressure light had turned on shortly after my first oil change (roughly at around 6k miles). I had the service done at a trusted service shop back in April 2021. I wrote it off mentally thinking that it was just a one off thing and that the shop may have made a mistake and underfilled the engine because of unclear specifications between the mazda6 Turbo version vs other models within the same lineup. I measured the oil and confirmed it was low and topped it off with over a half quart of oil and never bothered with it again. Six months later I return to the same shop for an oil change at 11k miles. I had no issues up until the 17k miles month mark when I am about to schedule the oil service the low oil pressure light turns on once again. I top it off and go online to see similar experiences with the same issue experienced by other drivers.

The issue I am experiencing is one that many are in regards to the oil consumption. My check oil light came on prematurely in regards to the recommended scheduling for these sorts of vehicles, at around 3500 miles approximately. This is a vehicle that experienced this issue under 10k miles.

Visibility/safety issue with OEM Mazda windshields. Objects appear highly distorted from all angles, making it hard to judge distance, read road signs, and drive safely without a disorienting level of distraction occurring at all times. Some objects appear magnified while others seem shrunken, as well as shorter or taller than they actually are. Straight lines appear rippled and in some cases, completely broken. Operating the vehicle for more than a few minutes results in rapid eye fatigue, motion sickness, and vertigo.
