Brake Sensor problems of the 2014 Mazda CX-5

Went in for a service around 55,000 miles and was told that new rear brakes were needed. Got a second opinion and was told that they could go a little longer. Started hearing squeaking, took them back to the mechanic who said they needed replacing. Replaced at 59,000 miles. Went in today 7/26/18 and was told my rear brakes were at 4% and would need replacing by my next visit. This would mean 2 rear brake replacements within 10,000 miles. My front brakes are still fine. I see many complaints about this for the cx 5, there a several tsbs out. Called Mazda who said they weren't aware of this problem and that brakes are considered a normal part of wear and tear. My second issues is that when I put my car in park and attempt to shut if off but it will not power off. This doesn't happen every time, but probably every 4th or 5th time. I read online that it's a transmission sensor issue and that the transmission sensor needs replacing. Both of these issues are very prevalent and I'm hoping there can be a recall on both.

2 issues so far with this car: 1st - rear brakes seized up after 30k causing a trail of smoke to follow my car while on the highway, followed by an emergency stop on the side of the road. The hub, rotor, brake caliper, and tires became so hot that the tire pressure sensor went off and upon inspection, the tire pressure had increased from 35psi to over 50psi (tire pressure gauge did not go higher then 50) due to heat. Was told that due to salt and sand (live in cold climate) corrosion caused the issue. Rear brakes and rotors replaced @ $208. 95. Currently fighting Mazda for a refund as this is clearly covered under the 3 year 36k mile warranty per TSB: 04­005/15 - see warranty section on 3rd and 4th page. I had family in the car when this happened and am worried about the long term safety of this car and it's braking systems. A rear tire blow out caused by this issue could have caused a fatal crash at highway speeds. 2nd - I have replaced the windshield on this car 5 times now in under 30k miles. I have been told repeatedly that this is due to rock chips, but twice the crack appeared out of no where while the car was parked in a temp controlled garage overnight. I have never had this issue with any other car I have ever owned. The windshields are always on a month long back order and driving with a cracked windshield is against the law, so every time this happens I am out of a car for a month and have to fork over money for a loaner so I may get to work. (Mazda and insurance company refuse to offer or pay for my loader car, or I am told there is not one currently available and I am sol).
