Chevrolet Customer Service Issues

I have a [redacted] Chevy Camaro that I absolutely adore, but it has been plagued with various issues. Recently, it has been shaking when driving at 45-50mph, which seems to be a common problem according to what I have found. I took the car to the dealer while it was still under warranty, and they kept it for three more weeks. GM advised me to flush and change the transmission fluid and drive [redacted] miles to see if the issue persists. However, after digging deeper, I discovered that GM is aware of a torque converter issue in certain model years and only wants to change the fluid multiple times. I am concerned about what happens after my warranty expires. I have been in touch with GM's warranty division for the past four days, but I have yet to hear from an advisor as promised. I am definitely not willing to be taken advantage of. I am looking into the possibility of getting a warranty extension, especially considering there is a class action lawsuit against GM for this exact issue. I seem to have the worst luck with this situation!

Hello, I am experiencing issues with my [redacted] Chevrolet Equinox. When coming to a stop, the vehicle shuts off, and the engine occasionally jerks while driving and when accelerating after stopping. The check engine light has been on since I bought the car, attributing it to a dirty sensor. I have had maintenance including replacing the air filter, cleaning and replacing sensors, replacing the right lower control arm, and getting an oil change with an engine flush. Despite this, fuel efficiency has decreased. The car has [redacted],[redacted] miles, but the dealership assured me there were no past or current issues reported with it.
