*Headlamp *Hard to see at night; risk of being pulled over *yes *no *no Week of May 1st 2023...headlamp works...then turns orange...the goes out. Repeats this process consistantly ** Currently there is a notice from the federal safety agency that GM Extended Headlamp Module Warrant Unfortunately Dealership is unaware of that...and also GMAC Warranty Customer service The initial recall was for defective low-beam headlights and daytime running lights on certain GM makes and models that were prone to failure on more than 300, 000 vehicles. More complaints were received after the re-call, the federal safety agency opened an investigation on April 2017. One year later the recall was expanded to include an additional 180,000. In the affected vehicles, the headlamp driver module may overheat, which could melt the module under the hood and result in failing headlight and daytime running lights.

Both headlights failed at same time during night driving resulting in very low visibility with only the daytime running lights working. My safety as well as others driving on the road were put at risk as my visibility of the road was impacted and my vehicles visibility to other drivers was impaired. This problem has occurred twice within in the last year making the vehicle unsafe to drive. The first time we just replaced both headlights thinking it was a fluke but having occurred a second time within a short period of time is very concerning. There were no warning lamps and at this time has not been inspected by dealer as there is not a recall and is an expensive repair. This is a serious safety hazard and could have easily caused a bad accident.

The issue started with my back hatch opening on its own at random times. Found out this was caused by water entering the lift switch. That problem lead to the battery eventually going bad and then the headlights being blown due the bad battery. Not sure how water got in the back hatch ruining the sensor but this is costing me about $1000 to fix.

My headlights started going dim, and would go completely off. I had to continuously turn the headlights on and off to keep them working. This would happen every couple of minutes when driving at any speed.

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!!

We have a 2015 gmc acadia sle-2 with projector headlights. We can only see about 50-75 ft. Ahead with low beams, there is a dark line at hood level where the light cuts of into darkness. The light bounces up and down when driving this is very distracting and dangerous. It is difficult to see the shoulder of the road, I did not see a pedestrian until he was right beside me. The high beams are about the same as the low beams in our previous vehicle (2010 gmc terrain). I contacted our dealer who said there was no recall or tsb regarding our problem. The service manager said he will try to adjust the aim of the headlights. He stated he had done this with other customers but it was not a fix for the problem it may only help a little. I saw similar complaints on carcomplaints.com. We feel this a safety issue and needs to be addressed. We feel someone should drive this vehicle in a dark rural area (where we live and drive most often) and they would see the problem!!!

My recent trip from connecticut to atlanta,ga and then to vero beach ,fl was driven at night.I found myself having trouble seeing any road sign hanging high, and most road signs in general unless I used my high beam lighting. I brought my car to the gmc dealership in both vero beach,fl and watertown, ct where I bought the car. It was found to have a very sharp cut off of light and with in the design tolerance. Both dealers have no clue as it is in gmc tolerance and there is no replacement light bulb for the light assembly. They both agree there is a design problem. I am now stuck with a new car that has bad lighting and will need additional lighting or get a new car from someone other than gmc. I did contact gmc and was told that there was not much they could do as it was per design.my car has no additional lighting, not even a fog light. Just received a call from gmc. The car is ok by its design, and as of now I have no more options.
