The sunroof made a very loud popping noise and exploded while driving on the interstate on November 30th around 12:15pm in about 40-50 degree temperatures. There were no warnings or noises or any indications that something was wrong. The safety of myself and children were put at risk, as the glass came down into the car while driving on the interstate, and presumably the safety of other drivers if some of the glass flew off onto the interstate. A local body shop has taken photos, as have I, and we have filed a claim with our insurance company. Our local GM dealer did not want to cover the cost under warranty, claiming there was no way to prove exactly what happened. The vehicle has been looked at and temporarily fixed by a local body shop, but not thoroughly inspected. The body shop has ordered new glass and will inspect the vehicle next week.

On 10/21/2021 while driving about 65 mph on highway 80 in Sacramento my sunroof glass exploded. It was not struck by any object. The weather at the time was rain and about 60 degrees. Traffic was light and nothing near that could have caused this to happen. Fortunately the shade was closed preventing any glass to enter the interior. Its been in at the dealer Stevens Creek Chevrolet in San Jose since 10/21/2021 waiting for a replacement glass. This incident could have injured anyone in the vehicle if the shade had not been drawn. So far it appears it is being handled as a warranty issue.

In late May, 2021, an "over-the-air" software update was forced onto our vehicle by GM. This update was initiated, and resulted in a failure of the over-the-air system. We brought our vehicle in to our dealer, who indicated that the "module" is bad and a part is required to fix it. This part is reportedly "on backorder" with no known ETA. This has resulted in various notifications (turn signal indicators, and unknown other notifications on the dash) as well as our center console (music, nav, etc.) to become unresponsive. Since the "module" failure, GM has issued two additional safety recalls. In the paper notices we received for the safety recalls, GM indicates that they had been "prompting owners through the vehicle's radio screen" for a month, via this over-the air system, of which, ours has not been functional since late May 2021. The last of which is a power steering recall, which may result if loss of power steering functionality. Due to our inability to know the recall existed, resulting from the faulty "over-the-air" system, my family took a trip through the mountains only to return home to this recall notice. GM has been unresponsive in repairing the system used to notify us safety hazards related to the vehicle that we have purchased, beyond noting that they are trying to "get the part as soon as possible". No one has been able to indicate what this "part" actually is, to date. The possibility of this module failure, and our non-functioning module, presents a serious safety hazard to drivers with this technology who are not made aware of recalls and other safety concerns which may result in crashes and serious injury or death.

Vehicle will not start. Only 6900 miles. Battery fine, lights and radio work, windows and tailgate work. Car turns over, but just won't start. Read manual, did everything suggested. Clearly an electronic error. And, because vehicle could not be started, it could not be put in neutral. Tow driver had to drag car across pavement on flatbed. Could not be good for brakes or anything else down below. When arrived at dealership, could not get Tahoe off flatbed. Winch only pulls up onto flatbed, does not push backwards. Oiled the flatbed and shook the entire tow truck body to try to get it to slide down. No idea why this happened. But a couple of months ago same thing happened to a friend's GMC version. Clearly electronic failure in band-new car.

2021 Chevrolet Suburban, 79 miles on odometer when driven off lot on 02/22/21. Vehicle frame and suspension parts, as well as, control, steering, and powertrain parts have significant corrosion occurring. Vehicle was manufactured and inspected 11/2020. Vehicle was visually inspected by owner. Currently in process of trying to remedy with GM. Corrosion so early in vehicle life will undoubtedly lead to failure. I reside in Tacoma, Washington. Vehicle was purchased in puyallup, Washington. More photos available upon request. There are several more areas of corrosion than photo upload allowed for. GM claims 2021 models have a new process when manufacturing and treating metal. It appears to have failed. The climate here is mild, and road salt is not used in the area.

I've been receiving this message "service safety restraint system" since October 26, 2020. Surprised that I keep receiving this message and I've had this vehicle for 3 weeks brand new. Unsure as to what is causing the problem and currently seeking resolution of this.
