Seatbelt chime/ alarm is defective. See all youtube videos showing so. Seatbelt light and chime continuously stay on and chime alarm continuously rings even while seatbelts are on & locked in position. This is very distracting and a dangerous situation for drivers attempting to make it go off/ work correctly while driving. This seatbelt chime is defective is both when driving / in motion and stationary. Body/windshield area structural defect- there is a hole/opening that allows rain/ water to leak into interior of truck, leaking water inside truck interior from upper build seam, through the grab handle located at side of windshield in front of front passenger, then liquid drips down onto carpeted floorboard. This body structure defective opening/ hole is located somewhere between upper windshield seam and the interior front passenger grab handle at windshield frame. Water drips through this handle. This windshield leak defect occurs when the truck is in motion and when stationary. Electrical/ignition switch- turning on track with ignition key, ignition switch does not always perform correctly. It often disallows the ac, the windshield wipers, and backup camera to work, while everything else is working. Because everything else may be working, the driver may not notice that the ignition switch has been turned on incorrectly. This defect, especially the back up camera not working, and windshield wipers, is dangerous. The switch should be made to consistently work at all times the same way. This defect is noticed when stationary, but often when it's too late and in motion.
