2017 Chevrolet Camaro

I would like to report a safety concern with my car having a strong shuddering or vibration, including the steering wheel which I’m unable to move. When this happens RPM remain below 3000 rpm as if the the gears were having trouble changing, the shaking remains while driving in the city at around 25-35 mph and highway speeds at around 65-76 mph. My car was under warranty when this started happening, the dealership flushed and replaced the transmission fluid and it took care of the problem for about 2000 miles (GM has several bulletins in regards to the “shake” on different model vehicles since 2014). When the shuddering returned, I returned to the freedom Chevrolet where I bought the vehicle (actual mileage 53768) and explained the shuddering returning. I was advised to leave the car which now has been at the dealership for months and they refuse to fix the problem stating it is out of warranty. I provided all the bulletins I found on related issue which GM has stated they fix the problem by swapping the transmission on new cars but nothing has been done on the cars that have the existing problem because “there is no recall” as the service advisor stated. This problem could’ve been resolved when I took the car the first time but I wasn’t aware of the severity of the problem or that I would have so much trouble with the dealership now. All I asked is to honor the warranty as the issue was brought up when the vehicle was still under warranty and has less than 60,000 miles.

The blender door that controls the air flow will close all the way and causes fog build up on the front windshield constantly whether it's cold or hot outside. It also randomly changes from hot to cold during driving. This is a concern due to drivability with the windshield fogging up or the comfortability of driving in extreme conditions ie... Hot, cold, or rainy conditions keeping the temperature in the car to see. Thank you for your time.

Shudder in the transmission. My camaro shudders between 40 and 50 mph. It had a recall and was taken in for the repairs. It was a transmission fluid flush and a change in the fluid. Something like that. The problem is shudder isn't fixed it was for a while but its back. There's definitely something still wrong with this. Is it causing the car more damage? I believe GM should repair all the recalled vehicles right! This is an issue and a huge nuisance. Shudder problem is still there!

GM has a service bulletin about issue. it involves all 2016 to current Camaro Convertible models. Back window that is sealed to the top just suddenly pops out. Rolling down window at highway speed while top up just pops out back window. the service bulletin states that and insufficient amount of primer is used during the assembly process. This allows the material to separate from glass. Window just pops out. purchased car new november of 2018 with 50 miles on it. car is garage kept and has less then 17000 miles. i am on my 3rd top. Gm will not cover the serious and potentially dangerous problem. TOP right of passenger side window failed. driving with top up and window open will further seperate glass from top and blow out. car is not safe to drive with top up.
