2017 Camaro transmission shutter not shifting right sometimes hard to stop

- St. Peters, MO, USA

Within a month or so after purchasing this vehicle with less that 20 miles the transmission would studder. I informed the dealership several times. I was told this was a known issue and it was just related to transmission fluid type. I brought the car in for a transmission flush and the problem seemed to go away. It has returned and is causing safety risk. Besides the annoying grinding noise, I have experienced safety related issues concerning this issue. At the moment you need to accelerate the car pausing and slips gears. This has put me at risk on many occasion since owning the vehicle. When needing merge or get over into traffic this has been very dangerous. GM has made no attempt to permanently fix the issue.

My vehicle dies while going 60 MPH or at red lights, creating a dangerous situation in traffic or on the highway. At times when yielding it feels like I've been hit by another vehicle from behind, the transmission does not downshift normally, and the TSB (see attached) proves that General Motors knew about this issue and did not notify customers or recall the vehicle for repairs. I have 2 issues with my vehicle and both issues remain unresolved even after utilizing the power train warranty. My vehicle was taken to the dealership for repairs multiple times, the "check engine" light was on the vehicle, no one checked it, and General Motors did not honor its Power Train Warranty Obligations, "the defects remain unresolved". My vehicle is dangerous to operate, I have tried working with General Motors to arrive at a solution, "But I should not be forced pay additional expense for issues General Motors knew about a, issued TSB's warning dealerships, and made no effort to notify customers. I am reporting this issue to the NTSB before providing a 30 day Notice of Intent to sue, to General Motors

Transmission in the 2016 and up 6 speed manual will pop out of second gear and making horrible grinding noises upon engaging and releasing clutch. I know several people who have had this issue and they told me GM is aware of the issue but ignoring it but it is a safety issue because it leaves a person in neutral in traffic when shifting to second it will go in and pop out. It is defective transmission housing in these expensive cars and mines has been doing it since I have had it and it is definitely the defective transmission housing and there is even a YouTube video on it. This needs to be addressed before Gm gets sued for this. Pandemic has made it even harder to get dealership to get stuff done because personally my car sat at Butler Chevrolet in Macon two months and they still never touched it and told us to come get my vehicle because they had no one to work on it and they had us in a loaner car with improper tags and registration issues and we reported that to local authorities and we are planning to sue them also if they don't settle for the discrimination and hard time they gave us letting my car sit months for no reason just to tell me they had no qualified technician to work on it and they had got my car full of ants and insects. We need this recalled so that anyone with these dangerous transmissions will get it repaired. Don't do your customers like this we are well aware of what's happening here. We pay good money for these cars. Recall these things before it leads to bigger class action issues and I'm a car truck guy and very mechanically inclined and have many friends who have these cars in manual and some of them have had transmission replacement due to defective housing and that solved the issue.

I began slowing down for a traffic light and experienced what felt like a car hitting me from behind. The problem is, "no one was behind me". A few days later I began noticing a distinctive shutter between 40 -70 Mph. under my seat, " It felt like I was going over rumble strips. I began researching this issue and learned that GM issued a Service Bulletin ( 18-NA-355 ), and the problem is a "known Issue". My question for my Senator is this "why wasn't a recall sent out"" Apparently a major car makers can get away with designing, building, and marketing a product with know problems which could lead to more serious issue. Since the issue deals with the power train, transmission safety, and the safety of the drivers, "How was GM permitted to simply issue a service bulletin? I followed the instructions and the dealership did not want to complete the work, "I had to write to GM and ask them to mandate the service on my vehicle. After the service my vehicle ran ok for a while, "but now I have strange shifting, slipping, clinking, and a violent jerk at times. How can the NTSB allow a vehicle with issues on the road" Again, this is a question for my Congressman and Senator.

When I place my car in park, I get a message on my display that says -€œshift to park-€. Once that message comes on, I cannot turn my vehicle off and have to keep restarting my car until the message goes away, so it does not drain my battery completely. It happens every time I shift to park.

The car starts to shake violently at any speed and it does it all models whether it switches between V4 or V6 or V8 mode. I am taking it into the dealership on 10/01/21. I have found one 106 complaints on your site since Sept 21, 2021. The issue at hand is either a faulty torque converter and transmission. I have also found several hundred reports on the internet. And as of today GM has flushed the transmission only to have the problem happen again. I feel they know they have a costly issue at hand. I am more concerned about the safety factor and my family in the car and it decides to fail at highway speeds.

The car vibrates when driving at speeds over 30 mph. It feels like you are driving over rumble strip. It does this every time I drive it now. It also shifts hard as it changes gears. I had to have a new rear boot put on the passenger side. All of the grease in the rear wheel boot was all over my wheel. There is a roar in the rear end when you first pull out onto the road. It feels like it is in the rear axle.
