I just purchased this vehicle and within a day, it was already giving an alert that something was wrong. Says "action required, shift to park". My car was in park. It was not shutting off due to the notification, which leads your battery to drain. The next day, as I was driving with my kids, the headlights start flickering, and then shut off. It left us driving in the dark and nearly causing a wreck because someone didn't see us coming because it was too dark. The dealership said they look at it, so I don't know what will happen moving forward. It's definitely not safe unless the issue is addressed.

While driving the all the the service lights came on on the dashboard and the system as well as the stabilitrak notification. The car begin to not want accelerate and I had to put on the hazard lights on a drive very slow home. Upon arrival home the car would not start but would not power off either and the a "Shift to Park" warning message is displayed.

The headlights barely light up enough roadway to be of any use at night. Obviously can't drive with high beams constant. The only help is to use the fog/driving lights. However, that only lights up about 30 feet in front of the vehicle. Driving at night is hazardous to one's health as you cannot see far enough down the road to avoid anything that is imminent on the side of the road, you can not see to avoid anything on the side. PLEASE HELP. Also, the manual is explicit about not using aftermarket headlamp bulbs to try to correct the problem.

Can not see at night with low or high beams. Lights are very poor and dim. Transmission always feels like it's slipping( 50,000 miles ). Shifts hard.

Headlights are so dim that it makes driving difficult and unsafe, particularly in rain and on rural, unlit roadways. Virtually unnoticeable change in lights when changing from dim to bright, and no side lighting whatsoever to allow visibility of deer/wildlife, etc. in ditches. Even turning from a highway onto a side road in rural areas is difficult and dangerous. I have found numerous complaints from others regarding this model, but no recalls or solutions.

I have a 2019 GMC Acadia that has had no vehicle damage and less than 29K miles. The vehicle has condensation in the headlamp on the right front. No damage at all to the vehicle. Clearly a defect in the seal. Doesn't even have to rain and moisture will be apparent in the headlamp. GMC has offered to pay 60% of the repair costs of a $400 part and $1200 labor bill. This clearly needs to be investigated since they have had issues in the past of headlamps issues in the Acadia models and others.

The headlights are not bright enough to safely drive the vehicle at night on low beam, and the high beam makes very little difference. It is worse when the roads are wet. When you put the high beams on, the lights do not seem to get any brighter. I have taken it to a GMC dealer twice and was told the headlights are working the way they are supposed to work. If that is the case, it is a poor design and needs to be corrected. This has been an ongoing problem since we purchased the vehicle new,

The contact owns a 2019 GMC Acadia. While driving at night, the contact stated that the headlights were barely visible because they were blacked out. The vehicle was taken to ken nelson auto group (1100 N galena ave, dixon, il 61021, (815) 288-4455) where it was determined that the headlights would not project too far. The contact attempted to call the manufacturer, but the call dropped. The vehicle was not repaired. The failure mileage was unknown.
