Your dealer confirmed the problem but said it's normal for this vehicle, though this warrants further investigation given the safety risk.

Your rear windshield/liftgate glass shattered without warning after six months of ownership, even though the vehicle hadn't been in an accident or experienced any obvious impact.

Your hood vibrates noticeably at 50 mph, especially near the windshield, which is distracting while driving.

These issues involve the hood's attachment or mounting system and the forward collision detection sensors.

The hood support rod under your hood gets extremely hot after driving and can burn your fingers if you touch it without protection.

Your hood vibrates while driving, and in sunlight or cloudy conditions, light reflecting off the hood flickers in your vision in a distracting way.

Getting the hood inspected and possibly adjusted or replaced may be necessary to resolve the vibration.
