    Experiencing a known excessive oil consumption issue. Low engine oil warning light came on and upon checking, oil was low. This occured at 4000 to 4200 miles. It occured again about 4000 miles later and again at a similar interval. I notified the dealer and scheduled a repair date but I am concerned of other possible damage that may have already occured due to this issue. An oxygen sensor needs to be replaced and is most likely due to the engine malfunction. The cause of the consumption is said to be damage to the valve seals on the exhaust side.

    During a night drive, travelling approx. 40mph, car warning system audio blared a warning and suddenly braked causing car to skid (was raining) and causing driver to also jolt forward with momentum. There was very little time between beginning of audio warning and car slamming on brakes.

    The latches inside the driver's seatbelt receptacle feel like they wear out over time. The only reason I can tell is because there is a really noticeable creaking that develops from inside the receptacle while the seatbelt is connected. This is worse for drivers with bigger waists and as the driver's waist continues to tug on the seatbelt during operation, the creaking gets worse over time. There are no electronic warnings. The seatbelt still properly connects and there are no electronic messages saying that anything is wrong with the seatbelt. My driver's original seatbelt receptacle has already been replaced once under warranty at a Mazda dealership. Now the second seatbelt receptacle is starting to do the same thing again after about 6 months of use. I fear that even if I get it replaced a second time, this will just continue to happen. Perhaps there is a manufacturing defect. As this issue continues to get worse, I fear that this creaking will develop into a major failure with the seatbelt connection itself.

    Purchased car in January 2020 and within a month/few thousand miles the low engine oil light came on. Almost two years later car continues to burn excessive oil triggering low engine oil light. Dealer doesn’t acknowledge an issue, Mazda still doesn’t have a repair. Owners required to pay for excess servicing until a repair is issued. This is a widespread problem impacting the engine.

    Strong unburnt fuel smell had just started at 6700 miles. Mazda Dealership stated that they would not be looking at my car and that gas smells are normal... After this encounter, I had 2 mechanics look at my car. Both had concluded that the smell predominantly comes from near the rear driver wheel, under the body, and that it is an extremely dangerous situation. I am a full time student and do not feel safe driving this car to class but I have no choice since Mazda is neglecting this issue. I also reported to the dealer that my brakes seem to be defective since they are causing excessive shaking when applied. Dealer informed me that they do not warranty the OEM brakes that came on my car, however Mazda Corporate informed me that they do. I do not feel safe driving this car knowing the car may combust and harm me and others on the road. The brakes also do not inspire confidence. A complaint has been filed with Mazda Corporate.

    After roughly 2,000 miles of driving, the low oil light comes on. The engine is burning oil. Mazda has issued a TSB on it, but they have taken no action to fix the issue. Right now they just top off the oil.

    The engine is burning oil. Oil and filter were changed at 5000 miles. At about 9000 miles, the engine oil level light came on. Topped off with oil and took to dealer, they confirmed no oil leaks and changed the oil.

    This new car has less than 8000 miles on it and suddenly 3 of 4 BRIDGESTONE TIRES Turanza el440 215/45R18 89 have sidewall bubbles. Interesting that there are a ton of issues w sidewall Bridgestone tires on line yet the dealership keeps claiming the car must have been run over a median? Without any damage anywhere on the car? Come on.. it is clearly a manufacturer defect. They have history with sidewall bubbling. Consumers getting shafted at best and maimed at worst. Do something please!
