Car lulls/jerks when accelerating from low speeds car lacks power most of the time and performs poorly engine loses power, several occurrences of what would appear to be limp mode ( can't get passed 2000-3000 ) rpms car has erratic idle rpms, sometimes high and sometimes low i've recently heard the engine roar while idling and hissing from the engine bay when shutting off the engine also sounded like the car was dieseling after shut down likely because the car was beginning to overheat from the immense stress in the engine from running too lean car has poor sound absorption in the cabin, sounds like you're in a airplane every bump it goes over reverberates through the car for an extremely unpleasant and unsafe experience feels like there is excessive play in the front axle wheels seem to drag and thud/thump like there is a flat when there is not i've had my wheels aligned twice already, they've balanced my tires several times, even changed a wheel bearing (i am aware of the tsb released to address these concerns and you blame it on a bearing) nothing makes this better and it is getting worse my car has been to the dealership for this complaint 3 times already this year ( yes that is every week out of 2020 so far). this is becoming a complete burden in my life and i am not going to be the person who has to die for mazda to address this
