“Purchased new 2020 Gmc Acadia denali in dec 2019. Vehicle was equipped with several dealer accessories include roof rail cross-beams. These were not in stock at time of purchase and returned after 1 week to install. After picking up the vehicle on my drive home, I heard a whistling/humming noise coming from the exterior at about 30 MPH. As I entered the highway and traveling at 65 MPH, the noise was deafening and the vehicle did not handle very well, vibration in the steering. I immediately returned to the dealer and determined the noise was from the roof rail cross-beams. …”

Water is getting in the electrical area somehow. I've taken it to two chevrolet dealerships, but no help.”

NHTSA complaint #11746751, filed 2026-06“Received a power steering reduced notice when starting the car, noticed shortly after driving the temperature gauge had not moved from its resting position. A few trips later it still had not moved and the check engine light came on. Mechanic looked at it said it may be a sensor quoted $1k to fix. A few days later it randomly started working and the light went off so I did not have it fixed. About 4 months later the same code displayed on the dash with the same issues. This time I noticed the ac would not work either it only blew out hot air. …”
