Built my T in 2011, got a couple thousand miles on it and noticed while down at the NATs cruising around Lake Tahoe that the column got a wiggle in it while the car is at speed. Closer inspection revealed the tilt mechanism had developed slop in it. When I got home, I pulled the receipt and called Speedway and told them this column was falling apart, they asked what part number it was then offered up to send me a new GM column at no charge and call tag to return the bad column. They also picked up the shipping both ways. Real pleasd with Speedway's customer service. The column was made by CPP and is one of those defective units made abroad. Apparently there are some Helix tilt units that are falling apart also. Read a thread on a guy that just finished his car and pulled it out of the garage and the tilt mechanism and steering wheel completely disengaged leaving no way to steer the car. If you are wondering do a google search on it.
