“I recently purchased this vehicle from a dealer in FL, but unknown to me at the time was the headlight adjuster on driver side was broken, causing the aim to drop to the bottom limit. This causes only the passenger side light to illuminate the road. I discovered this problem about a week after purchase. The dealer does not seem to be willing to correct this issue. This is a common problem for these vehicles, verified with online search's. The fix is to replace the entire headlight housing which is quite expensive, and then the labor to remove and replace the front bumper assembly.”

“There is a serious cabin air pressure issue in this vehicle. When driving at any speed with the windows up, there is a booming inside the cabin, as if the passengers are inside of a subwoofer.
