Engine Clicking And Tapping Noises problems of the 2013 GMC Terrain

In August, 2019 I had the oil changed and when I wen to leave the parking lot and put the car in reverse the car sputtered and the engine stalled. This happened several times. I then brought it to a dealership. They replaced the timing chains and actuators ($1,416. 60). Two days ago there was a ticking sound and then while I was in gear (drive) waiting for the garage to open, the car started trying to "buck" forward while I had my foot on the brake. I called the dealership and was told that this model with lots of miles (under 70,000) tend to burn oil. I added a significant amount of oil (none on dip stick) and now the vehicle is running fine. Why is this car burning so much oil? I have never had a car burn oil and to be told by a dealership after it was supposedly fixed that burning oil is normal is disturbing as is the unreliability of the car. Will it buck again or die again?.

The car started to "buck" and making a tap tap tap noise like a lifter tapping while driving to work. When I got out of the vehicle, something smelled hot. Checked under the hood and there was nothing wet or steaming. No check lights ever came on. Later at lunch, I left and the tapping noise was louder and the heat gauge increased fast. I stopped at a repair shop. While I waited I checked the oil. There wasn"t any!!! at all. The dipstick was milkey. The oil fill cap was wet inside and milkey. Underneath my car was covered in fresh oil. It was determined to be a busted rear main seal. 4 qts of oil added so I could get home. My mechanic confirmed the diagnosis. He was shocked. He found gm bulletin 14882 online. What is described in that video is exactly what happened. We had a sudden hard freeze x 3 days. The pvs connection at the intake was full of water. When that froze, it blew out the seal. My car has 88,000 miles on it. There are videos after videos online of the same engine doing this exact same thing. I called gm. The best they could do is tell me to report to you.

I had just purchased the 2013 GMC Terrain denali and noticed that it has a bogging sensation in the steering at idle when turning. It feels like the steering is going to cut out - almost like not fully enganging the clutch on a manual transmission when the engine is about to die. Very noisy and annoying in the tight parking garage when you have to turn the steering at a standstill during idle. There is a ticking noise coming from under the dash that sounds like a construction worker jackhammering about 1 block away with the windows up. It can also be described as a helicopter hovering overhead at around 200-300 feet. You can only hear it from inside the cab. I should have noticed this during the test drive, except that the radio was on and there were no tight steering situations. I was told that both of these items are normal by the GMC dealer. Be sure to test out these two scenarios when test driving. Too late for me, and unfortunately I have to live with it but would rather not.
