While driving, I got a message stating on the screen stating that transmission needed to be serviced. This was very scary as I slowed down and then was not able to put the vehicle in park and the parking brake was not able to be disengaged to be able to move the vehicle. After moving the transmission shifter back to different positions, I was then able to put the vehicle into Drive and then park it where it wouldn't move after that. Dealership now says that there is an issue with the transmission valve body that needs to be replaced.

23 Escalade L87 engine and transmission issue along with rear cross traffic alert emergency breaking. @ 8600k lifter failure (repair) @ 8750k transmission toque converter replacement @10600k spark plug replacement rough idle @17k in for hard down shift transmission valve replacement @21k in for lifter and same transmission down shift issue Service advisor advised that the lifters need to be replaced again and the hard down shift failed to be fully addressed. The upper level from GM advised no remedy could be found until service bulletin could be resolved. No repair work to be performed. To release to customer as is until engine replacement can be performed. So GM is forcing us to take back our vehicle on the road with a failing engine that needs replacement but due to not having enough stock to repair in timely fashion are placing us back on the road until one can become available. This now opens us up for massive catastrophic failure with my family on the road and not to mention others on the highway and public road system. I’m astonished that GM would do this to their customers and jeopardize the safety of their customers and other citizens on the roads. Something has and needs to be done. They are now placing my family and other lives in danger to save money. Vehicle serviced at field’s Cadillac St. Augustine Fl and recently at Randy Mario Cadillac Jacksonville Fl.

My wife was driving this vehicle home after dropping off kids at school when the engine suddenly stalled in the middle of the road. Luckily no one was directly behind her or she would have been in a collision. After being towed to the dealership, they informed us the engine "failed". There was no check engine light or warning message prior to the engine suffering sudden and catastrophic failure. Vehicle has less than 28k miles. The car is currently at the dealer with no time frame for repair because the engine is on "back-order".

I called dealer and told them that the suv was making a ticking sound and played them a recording of it. They told me that i could drive it in or call an 800 number and maybe get it towed. I decided to drive it in as towing it would prob take it to a dealer i did not know. There were no lights on indicating an issue. I was stopped waiting to turn left across traffic when the engine started making all kinds of clanging noise. At this point it quit and after a few attempts i got it restarted and towed it in to dealer the engine failure with out warning left me and my family in jeopardy in the roadway. Now i learn that lots of these 6.2 v8s are blowing up as my dealer alone has several of them out back waiting with no eta on repair parts coming. So not only were we put in pearl but i have 125k in a brick setting at the dealer. And givin a smaller auto that i can not pull trailers with. I feel endangered and ripped off pleasse help.

I was driving home from getting groceries when all of a sudden the vehicle starts to make a loud noise from the engine (no warning lamps/lights or any messages popped up.) I proceeded to go home and call my husband and ask for his help with the problem. I recorded a video of the car and sent it to him, and he said that it sounded like the engine is knocking and told me to shut the car off and call the dealership to further discuss the situation with them. After calling the dealership they towed my car to get it diagnosed. It has been a month or so now since leaving my car with them and they still cannot diagnose the issue.

INCIDENT: I was driving on the highway when I heard a strange "whistling noise." Thinking the noise originated from an old van in front of me, I passed it. The noise grew louder; the vehicle slowed very suddenly and, I pulled to the side of the road. The "low oil pressure" light came on just as the engine entirely blew. There were NO OTHER WARNING LAMPS, MESSAGES or OTHER SYMPTOMS. On-Star did not send roadside assistance for six hours and the battery died from extended use of the emergency lights. DANGERS: Experiencing catastrophic engine failure while driving on a highway presents obvious dangers as does sitting roadside for six hours (with a dead battery and no emergency flashers). INSPECTION: The G.M. Dealer (manufacturer representative) inspected the engine and confirmed that it was a catastrophic engine failure, requiring a new engine. The issue was also reported directly to G.M. The engine core, if need of further inspection, is likely either at the dealer, G.M., or a GM remanufacturing facility.

Friday 03/03/2023 Off hwy 34 was on i25 for about 5 minutes going 75 I accelerated to 80, to get in my right lane and out of the fast lane got over and a pop up came on my dash board, said press start. I then realized my car lost power on the interstate with cars going 75-80+ mph and I had no way of starting or pulling off the side of the road, as there was construction and temporary road w/ barricades on both sides. My car was stopped in highway traffic, I was pumping my brakes to notify the semi behind me that something was wrong so he wouldn’t hit me. How is a 2023 vehicle going to stop on the highway with evening traffic, no where to pull over and hope I don’t get in an accident, it was dangerous and there was no notifications on the dashboard telling me what was wrong. My fuel was full, battery was fine and oil life was good. There could have been several fatalities as it was on the interstate and I was in the right lane with moving traffic in both. Approximately 6:50pm. I do have photos and video of the incident. I hit the onstar button, was holding for several minutes, it disconnected, so I hit the SOS emergency button and the operator took my info including my location on I-25 near mile marker 255 prior to the exit near the park n ride. She advised she was sending cdot to get traffic controlled, traffic in the left lane was still moving fast, people were honking and going around the semi. My sister was in her Cadillac in front of me stopped with her hazards so traffic behind could see the hazards. Cdot arrived about 15 minutes later, and then followed by a State Patrol officer. He advised ME TO GET IN MY SISTERS VEHICLE, and go to the park n ride at exit 255 and the tow truck and office would meet me there.
