Steering Noise problems of the 2012 GMC Acadia

Tl the contact owns a 2012 GMC Acadia. While driving approximately 25 mph, the steering shook and made noises. In addition, the service traction control and check engine indicators illuminated. The vehicle was taken to an independent mechanic, but they could not diagnose the failures. The manufacturer was made aware of the failures. The dealer was not contacted. The vehicle was not repaired. The failure mileage was approximately 105,000.

Noticed odd noise when turning steering wheel. Upon having noise checked discovered that the rack and pinion box as well as the power steering pressure line were both leaking. Auto technician advised repair/replacement necessary as noise would get worse and steering would become more difficult in a short time. Technician stated that they have replaced numerous rack/pinion units on this make of vehicle. Check of the internet finds that this statement is true. Only 76000 miles on vehicle. Replacement/repair not covered by warranty. Rack and pinion and pressure hose replaced at a cost of almost $900. 00.

I have had some issues with this vehicle including a failed brake booster and my rack and pinion steering mechanism is currently being replaced due to leaking and probable failure, which I understand is a common problem with these vehicles. I was hearing noise coming out of the steering column when turning for sometime now. I was told that the hydraulic mechanism may fail and cause sudden more difficult turning without replacement. I have also owned another 2007 Acadia and had to have a power steering pump replaced 4 times.
