2023 Chevrolet Silverado Visibility & Wipers Problems

I needed a replacement driver-side windshield wiper arm for my 2023 Chevrolet Silverado 1500 LTZ Z71 with factory rain-sensing wipers. GM's electronic parts catalog directed the Chevrolet dealer to part #23387855. The dealer physically compared the part to my original arm and confirmed it was the wrong shape and would not fit. The dealer opened a formal Catalog Omission/Error (COE) ticket with GM. I was then informed that GM redesigned the wiper arm on my truck. The correct redesigned arm has been ordered, but I was told there is no estimated availability date and that it is not currently available through GM dealerships or GM's parts distribution/warehouse system in North America. This is a safety concern because a damaged or failed wiper arm could leave an owner without proper windshield visibility during rain or severe weather. I am also concerned that the passenger-side arm may have the same catalog and availability problem, although this has not yet been confirmed. I am requesting that NHTSA investigate whether this issue affects both wiper arms and other 2023 and newer Silverado 1500 trucks with this wiper configuration nationwide.

What component or system failed or malfunctioned, and is it available for inspection upon request? Glass sunroof blew outwards driving 60mph on the highway. No other vehicles were around and I did not see anything impact the vehicle. The glass was broken outwards and created an 8” by 8” hole in the sunroof glass. There was no extreme temperature differential, approx. 55 degrees outside. It has been repaired and not available for inspection. How was your safety or the safety of others put at risk? It sounded like a gunshot inside the truck, causing extreme distraction at highway speeds. Luckily the interior shade was closed and caught the glass, but if it was open all of the glass would have fallen on the passengers. Has the problem been reproduced or confirmed by a dealer or independent service center? No the dealership did not consider it a manufacturing defect. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Insurance inspected the vehicle and it was covered under a glass claim. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No indication prior to the incident at all. It happened out of nowhere.

Windshield wipers have stopped/paused during operation on two occasions midway through clearing rain from the windshield while driving down the road during rain events. Each time this has happened, the wipers have paused for approximately 2 seconds and then continued working without adjusting the controls. The vehicle is available for inspection upon request. If the wipers had not started working again, I could have lost the ability to see while driving on the roadway. This could have put me and family at risk of crashing, as well as other motorists on the roadway. The problem has not been evaluated at the dealership yet. There has been no lights, lamps or warnings this was going to occur either time it has happened.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while the vehicle was parked, the rear passenger’s side window suddenly shattered. The vehicle was towed to the dealer, who had not yet determined the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA Hotline for assistance. The failure mileage was unknown.

Rear view camera has moisture that builds up within the lens and makes it difficult to see what is behind when reversing. I've read online about many others complaining of similar issues from different source websites.
