Owner complaint summary

Oil burning and leaking as well after only 14,500 miles. I see there is a Class Action lawsuit filed against Mazda in late May of 2022 regarding faulty oil stem seals that cause oil to leak into the combustion chamber which will eventually cause O2 sensors to fail, catalytic convertors and engine valve failure. Dealer acted like they never knew about this issue and initially told me it was "normal" while the engine breaks in to burn oil. They attributed the "leak" to a faulty oil filter they put on during my recent oil change on July 8. Ridiculous that a brand-new car burns and leaks oil. Massive cover up by Mazda and a recall should be demanded. Apparently, they either do not want to spend 1000's of dollars in recalls or they do not have a fix. Either way, not owning up to this is a travesty and injustice!
