general problems of the 2026 Chevrolet Silverado 1500

Onstar super cruise, while using super cruise the vehicle tried to change lanes with another vehicle in the other lane. I had to fiscally override the super cruise to prevent an accident. This happened on three separate occasions.

Turn signals do not provide any audio signal letting you know they are on and working. Gm is unable to correct issue.

No owner manual, etc. Supplied. No safety information supplied. No maintenance information supplied. Dealer never mentioned when bought new vehicle on 4/22/2026. Went back next day and chevy does not supply any manuals. I could buy one for $100. If they were available. No car seat info or child restraint info. Nothing. Did chat with gm customer service, no positive results. Asked about recall n252540430. On owner manual being supplied. Dealer and customer service know nothing about it. I can look on phone, computer, or other digital ways to find info. Or sit in my car and use a tank of gas+ trying to find info on vehicle computer, if it is even there?.

The fin antenna on top of the truck has come loose, I got a continous message for the last 2= months. Service emergancy calling my truck is 6 months old now, but this happened 2 months ago. I took it to the dealership, friendly chevorlet where I bought it. Tech guy says I must have hit something. I called GMC and asked about product defect, was told thats not the case. I ordered a new antenna 4-12 26 GMC has none in stock which leads me to belie ve this is an ongoing problem. GMC says this is not covered by warranty. This is going to be a 600= dollar exspence for me. This antenna is for onstar and my phone connection.

0 audio works in the truck. No audible turn signals, warning chimes, phone calls, onstar. . . Nothing.

At 150 miles on the odemeter the tpm light came on I pulled off the highway, got out and checked all 4 tires. Not noticing any issues I got back on the highway and turned on the stereo. The speakers sounded like they were blown apart. Static and the sound of muffled vibrations. I drove to my intended destination and turned off the truck. After finishing my business at this location I started the truck and the tpm light was not iluminated. This is a hige safty issue. As a firefighter paramedic I have personally seen dead and mulated people that stoped on the highway and got out to check there vehicle and were struck by another vehicle. This issue is going to cause people to immeadiatly stop and get out of there vehicle thinking there is a flat tire. There is obviously a computer glitch in the 2026 cheverolet Silverado 1500 series.

My vehicle is listed as not being affected by any current recalls. When I purchased my vehicle in December 2025, it did not have an owner's manual in the glovebox, which I found concerning. Why do I not qualify to receive something as important as the owner's manual under that current recall regarding that safety issue?.

I purchased my new 2026 Chevrolet Silverado 1500 truck on 12/04/2025 from cma Chevrolet in [xxx] . When the truck was delivered, there was no owner's manual with the truck. I recently found that there was a recall associated with this issue. It is xxx. I thought that maybe manuals were now online. When I read the recall, it said that it is federal law that one be issued with each new vehicle. My VIN is not part of the recall. I contacted my salesman and he said that their parts department said that sometimes the manufacturer, gm, puts out vins in blocks. This does not make sense. How does a manufacturer know something that they did not do?? I would like my VIN added to the list of vehicles that are affected by this recall.
