“This car makes a loud noise (train horn?) when I first begin to drive it on cold days. It makes the noise for a couple of seconds and then stops. If I leave it parked until it cools off and try to drive it again, it makes the noise again. It's very loud and disturbing. I first noticed it when the temperature dropped to about 40 degrees Fahrenheit.”

NHTSA complaint #11677891, filed 2025-08“I was driving on a two lane highway going approximately 55mph. It was around 8pm and it was already dark out. There was nothing near me on the road. While driving, I heard a loud explosion/pop. I swerved into the opposite lane due to the sound. Luckily there were no cars oncoming. I was able to get back to the right side of the road and find a spot to stop/park. I then looked at my sunroof and it was shattered in a circular pattern. It was not from an external force.”
