  In November 2023 I purchased this vehicle. The dealership was made aware of the ripples within a few days of driving the vehicle. The windshield was defective and had to be replaced. The staff at the dealership did see the ripples on the windshield and agreed to replace the windshield. On December 14, 2023, the dealership replaced the original windshield even though they had the windshield since November 22, 2023. Within a few days of driving the vehicle, I noticed it also has ripples on the 2nd windshield. I have been to the dealership two times, and no one can see ripples. I have taken the vehicle to an automotive glass company who confirmed the ripples in the windshield. On February 5, 2024, I took the vehicle to a different dealership. The appointment was scheduled by a General Motors representative. The staff at the second dealership cannot see anything and took pictures to send to General Motors. The ripples in the windshield are distracting when driving in the daytime and nighttime.
