2006 CADILLAC SRX with 63000.0 miles

We own a 2006 Cadillac Srx awd that is having a problem with the traction control. Pretty regularly, when you are driving at a low rate of speed, the traction control will engage without warning. You can be turning in an intersection when it happens or just pulling out of a parking lot but when it happens, the radio alert will read "traction control engaged". You have to reach over and hit the clear button to get it to stop. When it happens, you lose power. If you are in an intersection, you have to be very careful & fast or you will get hit. It's very scary. We had a mechanic check the codes in the computer and it had these codes: C0046: left rear wheel speed circuit, C0228: left rear abs channel in release too long and a transmission code: P1793- wheel speed signal malfunction. Because of these codes, the mechanic couldn't tell what is going on. When he called the Cadillac dealership, he was told that we needed a rear driver hub assembly. Which has nothing to do with the traction control engaging. I found several complaints on this site about the same problem w/2006 & 2007 model Srx's. Then i searched online & their are hundreds of complaints about this issue. Some as early as feb. 2006. This is a safety issue that could result in death if not repaired. The dealers should know what it is & should recall all of the affected vehicles to repair them because they were faulty from the start. I hope something is done before someone gets hurt. Please look into this. Just search online & you will find hundreds of complaints. That's just the people that have taken the time to complain. Thank you
TRACTION CONTROL SYSTEM,
