NHTSA Complaint #11637003 — 2022 CADILLAC ESCALADE ESV

While driving, I noticed a very distinct knocking sound, that changed frequency and tone depending on how fast the engine was spinning or how warm it was. This noise I only noticed while walking outside the car or with the windows down. As a mechanical engineer, I knew something was terribly wrong with the internal parts of the engine (lifters, cam, main bearings, etc) as this type of sound I am familiar with in pre-emptive engine failure. I made an appointment with my local dealer (Massey Cadillac South - Orlando). I took it in. Within an hour of it being there, they asked me to leave and took me to a Hertz to get a loaner. I called a week later asking where my car is, they said they are waiting on a complete engine. I was shocked as the vehicle has under 47,000 miles on it. I am still without the vehicle 6 weeks later. Doing searches I noticed there are thousands of others with the same issue as mine and GM is well aware of this engine failure issue with their bulletins that they send to dealers. I am happy to have made it to the dealer without incident, however if it was my wife driving the vehicle, she would not have noticed the noise. She thought the noise it made was normal. Again, I am experienced to notice noises like this. GM should have recalled these vehicles MANY years ago.
