The contact owns a 2012 GMC Acadia. The contact stated that shortly after purchasing the vehicle, the check engine warning light illuminated. The vehicle was taken to the local mechanic who discovered that the catalytic convertor was faulty and needed to be replaced.

The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not contacted. The failure mileage was 130,000.
About 1 month ago While making a slow speed turn from a parking lot to a street the steering seemed to lock for no reason. After a brief moment the steering resumed normal function. I inspected the ignition switch and found nothing abnormal. Checked power steering fluid level, it was in the operating range. Unable to duplicate the issue at that time. On 3-9-23 while driving the vehicle started making an unusual noise coming from the engine. It seemed to be consistent with engine rpm. I believe it was the power steering pump. After stopping and starting the engine the noise was gone. A few minutes later while driving at slow speed the steering locked again, or the resistance was too great for my wife to overcome.

Was waiting on dealership to catch up to bring in for a transmission problem. I know it is transmission related due to not wanting to shift properly and the fact my friend has same make and model only about 100000 more miles than mine does was doing same symptoms and she took to 3 or 4 mechanics and all said nothing wrong..no codes show up...needless to say after about 2 months it stalled out on her on interstate with speed limit 75 and she barely moving. I myself was at a sharp curve in turn lane waiting on traffic and when I braked to stop it made horrible sound and felt like brake was pushed through floorboard. When I was clear to go i push accelerator down to the floor and am barely inching along and am now stuck in the road in a 90 curve where its hard to see traffic coming. This was very scary and traumatic having this happen. …
