GMC Complaints

The DIC randomly displays “check trailer wiring” then says “brakes connected” over and over. When this happens the brakes on the trailer quit working, all lights continue to work all the time. It hasn’t been back to the dealer yet but I will take it when I can. Other vehicles have no issues with this trailers brakes when towing. I have replaced the trailer pig tail 7 pin plug, cleaned all connections etc. The only thing that works so far is to disconnect one of 4 electric brakes then the DIC is silent and 3 brakes function. I even replaced some magnets in the trailer brakes but they were working prior to the DIC message that began on my second towing trip. There is a technical bulletin for some GMC trucks but my model isn’t listed as one. I believe it to be the controller or software since nothing seems to work as far as the trailer is concerned. It isn’t my trailers issue…I know they are going to say it is.

Many times after shifting the car into park, a message is displayed saying that the car needs to be put in park. It takes many time of turning the car on and off and moving the shift back and forth in order to get the message off and get the car to shut off. I notice that some 2017 and 2018 Acadia models have received recall notices addressing this problem. Our VIN number does not show up in the recall notices. Is there a reason why our car would not be covered as we have the same issue as cars that have received recall notices. Any help that you could provide would be very much appreciated. It is a very frustrating problem.

Mileage 65080. I’m the 2nd owner. I bought this truck used and have only driven it 145 miles. Crossing an intersection and the power steering turned off. Happened again the same day leaving Walmart parking lot. Turning the engine off will reset the power steering. Message on the instrument panel says stabilitrak service power steering.

Headlights have intermittent lighting failure resulting in brief flashes/blinking of the lights. There are multiple complaints and this is known by GMC, but there is no current resolution.

While driving reduce engine power light came on and the brakes gave out. I weigh 250 lbs and took all my strength to get brakes to stop car. I tow it and mechanic showed me vacuum brake pump blew up and went into engine. He replaced that and timing chain but still needed work. Towed it to dealer and it needs a new engine $11 000. The dealer informed me they see this alot. ! Why has GM recalled some on the vehicles that has this pump but not the terrain. This is dangerous. If my daughter was driving she couldn't stop this car. It's now junk.

There are 2 issues with this vehicle: #1) The rear window defrost causes an electrical issue that melted the plastic on our rear sliding window. Dealer claims we put something hot against the window but we did not. This appeared after we used the rear defrost. Several other owners have complained about this as well. #2) The vehicle is advertised as having adaptive cruise but it does not have this feature.

My radio is going crazy. Like going through every radio station, calls people. Its a distraction. And after researching how to fix I noticed thousands of people have the same problem. Almost cause an accident because of the distraction and this is obvious problem in GMC.
