Problems with 2010 Cadillac SRX WHEELS

My break going all the way dow when i have a bump on the streets i bring to cadillac dealer and they say everything is ok i can drive my car but gm has not recall for this safety issue

The bearings on two of the tires the emissions is giving me trouble i took it to a mechanic who changed everything car will not pass inspection

What sounded like a power steering issue turned out to be a big problem with the left front hub assembly. only if i made a hard turn would the car sound like there was grinding. i did not need to be braking for the sound to occur. soft turns did not result in the grinding noise. thinking that it might be the brakes, we took it to a pep boys service station. the mechanic immediately called us back to show us "a bigger problem than we thought". of the three hub assembly bolts, one was missing and the other two were loose and on their way to falling out. the mechanic asked if we had had any front end work done. we had not. we suspect the bolts were not installed correctly when the car was made and over time the bolts had worked their way loose to the point that the rotor had obvious play, causing the grinding noise. i shudder to think what could have happened and consider myself very lucky that i didn't lose the wheel off of the car, especially since i was on the highway only the day before. we consider this episode to be a near-miss safety issue.

Tl* the contact owns a 2010 cadillac srx. while driving at an unknown speed, the wheels seized. the accelerator pedal was depressed, but failed to respond. the vehicle was towed to a dealer where it was diagnosed that the hubs needed to be replaced. the vehicle was repaired, but the failure recurred months later. the manufacturer was notified of the failure. the approximate failure mileage was 65,000. updated 01/27/17*lj

I purchased my 2010 srx (used) in oct 2011 from king acura in birmingham, al. it had 23,000 miles on it at time of purchase. from the date of purchase i have had an issue with a rubbing noise when the wheels are turned to the left or right. the noise seems to be worse when the vehicle is cold. i have had the vehicle inspected at our local cadillac dealership, and though they did hear the rubbing noise, the technicians were unable to determine a cause. in addition to being very annoying, especially after paying premium prices for a luxury vehicle, i am concerned there may be a structural problem that will result in accident and injury. i am taking the vehicle back to the dealership, but i fear it is a futile effort as the mechanics seem to have no idea what is causing this noise. is this issue common, and if so, is it being researched and addressed by the engineers at cadillac? someone please address this and provide a fix! if a fix has been determined, please provide instructions on the procedures for having this problem resolved as soon as possible. *tr
