NHTSA Complaint #11658147 — 2023 CADILLAC ESCALADE

In May 2023 I bought a new 2023 Cadillac Escalade (because the engine on my 2021 Tahoe was being replaced—NHTSA 11658068). After owning the Escalade just under a year I started noticing it making odd engine noises, most often at a cold startup. It sounded like a ticking or vibration and was pretty loud. On April 30, 2024 I took the Escalade to Blackstone Cadillac in Fresno CA where they found Cylinder 2 was misfiring. They said it was related to TSB #19-NA-218 and recommended an engine replacement, which they completed, and I picked it up May 22, 2024. The new engine runs rough, tons of vibration, and frequently struggles with the automatic start/stop function at red lights. It will shut off and start up immediately, or it won’t want to start back up at all. Due to these concerns I took it back to Blackstone Cadillac in October 2024. The mechanics put my Escalade side by side with another Escalade and listened to both engines and they said it sounded the same and couldn’t find anything wrong with it. My Escalade continues to run rough, odd vibrations and problems with automatic start/stop to this day. I just received the recall notice “N252494000 L87 engine loss of propulsion” for my Escalade and was notified that a remedy is not available. I called the dealership and they confirmed, there is currently no remedy available for the recall on my Escalade. I am worried and scared to drive it because I was stranded in the middle of a highway with the same L87 engine on my 2021 Tahoe (NHTSA 11658068). I don’t know what to do.
