2023 Cadillac Escalade power train problems

“2023 Cadillac Escalade Sport Platinum, VIN [XXX], equipped with the 6.2L L87 V8. The vehicle has a recurring vibration/shudder during steady, light-throttle driving, particularly in the low 30 mph range and again around 53 mph. At approximately 53 mph, the vibration can remain sustained while speed and throttle are held steady and generally stops or improves when I accelerate. The selling Cadillac dealer has repeatedly road-tested the vehicle. The Service Manager personally reproduced the condition and confirmed that the vibration goes away when the vehicle is operated in L9. After further evaluation, the dealer advised me in writing that the vibration was “positively confirmed” to be caused by the cylinder-deactivation process and that it cannot be changed. The vehicle previously underwent the applicable GM L87 engine recall inspection and passed that inspection. I am reporting this because the vibration and hesitation are noticeable and sustained during normal steady-speed driving, and I am concerned about whether this cylinder-deactivation behavior presents a drivability or potential safety issue. I have not experienced complete loss of propulsion or engine…”

“About 11pm Driving 70 on freeway started feeling pull back and then started to hear a knock noise. So turned down the music and the knock noise was getting louder as I was driving so I went to the right lane as I went to the right lane I felt like the car was pulling back and slowing down even as I accelerated… knock got even louder and I decided to exit the freeway early instead of getting to my destination. As I exited the freeway the entire car shut down lights flickered check engine went on and low oil pressure flickered once but then turned off. I couldn’t get it in park couldn’t get the car to turn over. I was able to get out of the middle of the intersection turning off the freeway and pulled gas station called AAA. I’ve had no prior problems or warning lamps before this problem happened with the vehicle. I have videos of the whole incident that will not let me download on bottom of page. “2023 Escalade ESV, VIN [XXX]. Towed to Cadillac of Laguna Niguel. Engine knocked, then complete no-crank, suspected seizure. I need a case tied to recall N252494000 / NHTSA 25V-274 and special coverage N252494003. Do not authorize paid diagnosis. I need a loaner…”

“The engine is knocking between 10-30 mph and over 50 mph. The forward collision light lights up. This is the third time this has happened. I am very concern it will stall on me at high speeds”

“Transmission control module went out of the blue, caused limp mode on the highway and barely got off. Damaged the Transmission, had to replace by cadillac. 2 weeks later after i got the car back, blew 3 fuses and the starter while driving. Had to get towed back over 100 miles. 3 days later the engine completely blew and they had to replace it. this was the second time this happened, first since ive owned it.”

“The engine/powertrain malfunctioned on my 2023 Cadillac Escalade at approximately 29,434 miles, ultimately requiring complete engine replacement. During the engine repair, the Cadillac technician also discovered that the transmission cooler lines were leaking fluid. The dealership replaced all of the affected transmission cooler lines as part of the repair.The original failed engine was removed by the Cadillac dealership, so I do not know whether GM/Cadillac retained it. The failure involved the vehicle’s engine and created concern about the possibility of sudden loss of propulsion or engine failure while driving. Because this is a large vehicle routinely operated on public roads and highways, an unexpected loss of engine power could significantly reduce my ability to safely accelerate, merge, or move the vehicle out of traffic. Fortunately, I brought the vehicle in for service after noticing the abnormal engine noise before a complete failure occurred while driving. Yes. Heritage Cadillac inspected and diagnosed the vehicle. The dealership documented my complaint of a “weird noise on start up” that continued until approximately 10 MPH. The technician removed…”

“On [XXX], while driving my 2023 Cadillac Escalade ESV from the Salt Lake City area toward Las Vegas, the vehicle developed a serious loss-of-power condition in Utah. I contacted OnStar, exited the highway, and waited at a gas station. OnStar arranged towing to a Cadillac dealership. GM records document the tow at approximately 56,644 miles. At the dealership, I reported the loss of power. After initially being told they were too busy, I waited about 10 minutes and was then told the vehicle was ready. After returning to the highway, the vehicle suddenly lost power again at approximately 70 mph. Pressing the accelerator did not produce normal acceleration, creating a serious risk of a highway collision. I immediately returned to the dealership. The dealer then performed another repair. The invoice states the Service Engine Soon light was illuminated, soot level was 255%, and a service regeneration was performed. I was charged $406.16 and was again told the vehicle was ready. After leaving again, the same loss-of-power condition occurred. After safely exiting the highway, I recorded video showing the vehicle at approximately 38 mph with little or no acceleration…”
