My first incident on my 2015 GMC Acadia sle fwd purchased brand new was this year at 40000 miles. One head light went out and then the other in which the dealer wanted 400+ bucks to replace. The lighting is actually bad from the headlamps. They lights do not extended in front of you to see if you will be coming upon anything and can possibly run it over. My second issue at 41000 was the power steering. One day I heard a loud whining as I turned the corner on a city street and suddenly the power steering stopped. I looked in the manual and it says to put a certain type of transmission fluid in there, but I had just had a free oil change at the dealer about 3 weeks ago and they do not top off any other fluids. After putting the fluid in the power steering place, I noticed a leak. Come to find out the power steering pump is leaking on my car with only 41000 miles. A brand new car practically that cost 30,000 should not have issues so soon. Today, driving to work I almost lost it because my car all of a sudden started jumping codes "service stabilitrak; service traction control; traction control off; engine power is reduce' and my speed went from about 40 to 30 instantly. I was driving on a city street traffic while this happened and was unaware. Just think, if I did not put on brakes and was going at a certain speed and the person behind me is as well, and my car's speed just drop dramatically, what type of injuries could have occurred. I am very perturbed because this is the second gm car that I purchased with defects and my car just so happen to be omiited from any recalls. I own a 2010 chevy malibu as well and the power steering completely stopped working in 2015 and I had to pay 1300 to get it fixed, while other cars where on recall for the same issue. I'm so done with gm!!.
