Engine problems of the 2006 Mazda MAZDA3

Took the car into dealer for normal scheduled maintenance (oil change/tire rotation). Told that the #3 engine mount is cracked and needs to be replaced. Service advisor tells me that it is a general occurrence and that he sees 1-2 a week with cracked/broken #3 engine mounts. Mazda headquarters says that it is normal wear/tear on the car and will not cover the engine mount, even through a goodwill account, saying it is my responsibility because it is out of warranty. Service advisor says that these engine mounts should not be breaking and are not normal wear/tear. A TSB was put out in 2007 regarding #3 engine mount replacement, but no recall; however, a recall was put out on Mazdaspeed3 for a faulty #4 engine mount. This can be a major safety hazard if it breaks clean through due to Mazda's faulty design flaws. Service advisor suggested that I replace it because it can cause an accident and major engine damage if it breaks. Do not know if Mazda has remedied the situation with a new part or if the old parts are retrofitted to fix the problem.

Following a rear end collision, my 2006 Mazda3 mileage dropped from ~24mpg to ~8mpg, with no torque at all from ~20mph. Significant steering trouble, awful tire noise, and loud knocking when turning were dismissed by the local dealer as "well within specs". Requested brake caliper and alignment check, refused by the same dealer; tech performed a road test, declared the problem due to tire feathering and demonstrated 120mph tight curve as remedy. Three sets of tires, one set of wheels [3 of oem were warped], entire complement of motor mounts, two sets of rotors later, I'm about to replace caliper mounts and axles. Car is unsafe, and dealership disregard of warranty and tsbs, and of basic safety standards was outrageous, especially given (ongoing) [spine injury from collision was nearly fatal] circumstances.

Engine has failed after 41,000 miles. Bad lower rod. Mazda will not cover under warranty. Vehicle is still under warranty.
