Reply To: 2020 CT5-V Engine Popping Noise

I appreciate the time that you have taken to respond to my posting. I am a car enthusiast and this is not my first turbo. I know all about the sounds associated with turbos, like blowoff valves and wastegates. I can even play with the exhaust noise it generates. This is not a normal sound. If you read my original post you will see that the service manager at the second dealer I went to agreed that the sound is abnormal. The field service engineer came twice and tried two things that did not fix the problem. He then took audio recordings to bring back to GM for further review. (My car has been at the dealer since December 3rd.) Following the audio recordings, the engineer had the right turbo replaced. No change. Then, they “borrowed” the entire exhaust system from another car and tried that. Nope. Finally they tried one last thing, which I am not privy to. No, again. Sooooo, GM has agreed to buy back my CT5-V and credit it toward a 2021 model with all of the same options. I was told, yesterday, that it is built and awaiting shipment. Not all noises coming from performance cars, like this one, are to be envied by others. Some noises, like this one, are actually embarrassing when people are next to you as you moderately accelerate from a stop light. I am very pleased to know that GM (Cadillac) is doing the right thing here. I have been a GM guy all of my life starting with my ’67 LeMans. I will continue to be a GM guy. So, what is a 73 year old guy doing with a velocity red CT5-V? Simple answer. I can’t get into a Corvette much less get out of one.
