I am reporting a safety defect involving the uconnect touchscreen in my Jeep Grand Cherokee. Due to screen delamination, the display can lag or freezes, including the rearview camera image. When the vehicle is shifted into reverse, the camera images can be delayed, frozen, or not updating in real time. This results in the screen showing an inaccurate view of what is actually behind the vehicle, creating a serious safety hazard. Objects, pedestrians, or vehicles can enter the rear path after the image freezes but will not appear on the display. This defect creates a false sense of safety and undermines the purpose of the federally required rear visibility system. The failure occurs intermittently without warning, making the rearview camera unreliable when it is needed most. This is a known defect affecting Jeep Grand Cherokee vehicles equipped with uconnect displays, not normal wear and tear. The manufacturer has not provided an adequate recall or permanent fix. I am requesting that NHTSA investigate this issue as a systemic safety defect that increases the risk of backover collisions.
Delaminated bubbling dash obstructs visibility.
The dashboard is bubbling. Some of the bubbles can cause reduced visibility on the lower portion of windshield.
The front glass panel of the panoramic sunroof spontaneously shattered. The car was going approximately 45-50 mph when a loud "bang" was heard. Broken glass could be heard inside the closed sunroof liner. Upon inspection, there was no physical damage to the front end of the car, hood, or roof indicating that something may have struck the car. An inspection of the sunroof showed a sizable hole in the middle of the sunroof glass panel with accompanying cracks in the sunroof safety glass. The car can be inspected upon request. The safety of the driver and passengers could have been compromised if the sunroof shade/liner was retracted. The problem has not been reproduced although the dealer has confirmed that incidences such as this have occurred. The vehicle has not been inspected at this time, but an inspection is scheduled. There were no warning lamps or other notifications alerting the driver to the malfunction.
