Problems with 2010 Chevrolet Equinox WHEELS

I need to report that when driving on these icy roads that my awd equinox feels like it swerves? it feels like it takes me into the other lane most of the time. now, i don't know if its the awd causing it but other awd vehicles that i've driven have never did it this bad to the point that it feels almost like my back end starts going sideways.

Tl* the contact owns a 2010 chevrolet equinox. while the vehicle was being inspected, the mechanic discovered that one of the wheel lug nuts fractured due to corrosion. also, the timing chain was replaced three times and the engine oil was being consumed prematurely. the engine failure was not corrected and the wheel lug nuts were replaced. the manufacturer was not made aware of the failures. the failure mileage was 68,138.

Reporting failure of all four michelin latitude lt p235/55-r18 tires. tread is separating from sidewall on all tires. air leaking from 2; expect others to fail shortly. steel cords exposed and protruding from under tread. complete separation of tread form sidewall. *tr

For the past year i have been going to the dealer for my regular car check-ups and each time would complain that my tire pressure light would come on the kept checking the tire and found nothing wrong. they finally told me that the tires were doing that due to the weather to just ignore the warning. all of a sudden i noticed that the side wall of my tires were separating. i took it in and ask them why was this happening, i can see maybe one tire but all four. they said that i must have hit a pot hole but my tires had a lot of miles on them.in dec 2012 they said that i had 8/32 or greater for tread depth then jun 2013 they said that everything was okay and then oct 2013 they are saying that i have 3/32 or less tread depth. i do not doubt that i need new tires but i do believe that i have some defective tires and i can see one of them would be like this but all four..... *tr

When slowly turning the steering wheel to the right all the way to almost the very end and while advancing at a very low speed, there's a small high pitch noise and "thunk" of a sound that can be heard from the front-left of the vehicle, if the radio and ventilation is quite down. it does not sound healthy and is quite disturbing knowing that there's only 3500km on this 2010 chevrolet equinox ls would there be other complaints likewise? and please investigate. thank you *tr
