Steering Column problems of the 2015 Chevrolet Colorado

Tl the contact's son owns a 2015 Chevrolet Colorado. The contact stated that while her son was driving at 35 mph, the steering warning message appeared on the instrument panel as the steering wheel locked-up abruptly. The contact's son was able to pull the vehicle over, restart the vehicle and resume normal driving. The contact then took the vehicle to an independent mechanic who diagnosed the vehicle with a defective part inside the steering column. The mechanic then informed the contact of NHTSA campaign number: 16v054000 (steering). Watsonville Buick GMC (500 auto center dr, watsonville, CA 95076) was then contacted about the failure. The contact was informed that the VIN was not included in the recall. The manufacturer was also notified of the failure and an agent informed the contact that she would speak to a supervisor about the issue. The contact was yet to hear back from the manufacturer. The vehicle was not repaired. The failure mileage was approximately 50,000.

While driving I received a service power steering message followed immediately by a service stabilitrak message and lost the ability to steer the vehicle. This hapenned 4 times at varying speeds, including while entering the highway and at low speeds driving down the road at approximately25 mph. After shutting off and restarting the vehicle, the problem clears and the power steering functions. I took it to my local chevy dealer and was told it's an electrical short in some sensor in the steering column and it would cost me $1,800 to repair. The vehicle has only 44,500 miles on it and I purchased it new. It is no li ger under warranty.

When put vehicle in park I am often unable to remove the key from the ignition. I have to restart it & move steering wheel to another position. Often have to do several times before I can get key out. Dealer said there are complaints with vehicle being put in park & they said to move shifter in/out of park to get it to work. I can not figure out if shifter or steering column.

22 Mar while driving my Colorado lt at 30mph, warning light came on, with the message: �service power steering (ps), drive with care�. I cleared the message and another message came �service stabilitrak�. I went to work and parked it and 3 hours later, steering was normal. 23 Mar on the way to the dealer the truck had no problem with power steering. (o�reilly Chevrolet in tucson, az) and explained them the situation. The dealer test drove the vehicle and had no loss of ps. Vehicle was through the dtcs and found dtc u0420/42; torque sensor not properly learned. Dealer did pscm setup& cleared the dtcs. Service person stated they had to reboot computer. Afterwards, they drove the vehicle & had no malfunctions - $153. 24. On way home, had no problems, to include the weekend. From 26 to 29 mar18, had several instances in which the �service power steering (ps), drive with care� & �service stabilitrak� came on with the subsequent loss of ps. On 27 Mar 18, I received two emails from onstar stating the following: issue with stabilitrak� stability control system in your 2015 Chevrolet Colorado has been detected. Please service your vehicle within 7 days�& �issue with antilock braking system in your 2015 Chevrolet Colorado has been detected. Please service your vehicle within 7 days�. Took back to dealer with copies of above related messages, who stated this would allow to better pinpoint the problem with the vehicle. Service manager called later that day stating warranty has expired 2 months ago and that I would be responsible for repairs. He said steering column had to be replaced & would cost around $1,800, but after consultation with factory, they were willing to cover about half the cost and I would be responsible for about $650. Said that they would have to order the part � back order & no idea when the part would arrive.
