While driving on Highway 360 in Arlington, TX, the engine appeared to not change gears. It was between 3:30 to 4:00 PM, moderate traffic. I left HWY 360 and used the side lane. Later, the engine light came on. I checked the fluid levels and all were fine. This vehicle was last serviced in December 2022. The problem is unknown.

*safety issue* Escalade will shift violently into gear in either forward or reverse, causing vehicle to suddenly lurch. Condition is especially present when stopping at intersection on an incline. From a stop or rolling stop, the vehicle will be unresponsive to gentle acceleration for a second or two, then bolt into gear screeching the tires and launching vehicle violently forward. Likewise, from rolling stop then shifting to reverse to park, same lag with sudden burst of power. The effect is very similar to someone who is learning to drive a manual tranny in a muscle car. There seems to be no difference with transmission temperature, the intensity of the condition seems to be random, and difficult to intentionally recreate. Vehicle has been in shop twice, received the 18-na-355 bulletin service, and problem persists. Dealer indicates that transmission is operating as designed. Additionally, the transmission shifts harshly both up and down through gears 1-3 when gently accelerating or braking. Again, similar to someone who is learning to drive a manual transmission. I dont consider this condition a safety issue, but an annoyance and may well be related to the "lurching" condition.

When I am driving on smooth surface streets sometime there a feel of intermittent juttery ride which feels like you are riding over very small speed bumps very close together. I was told by two (2) mechanics that there is a problem with the transmission that is causing this. I started about two (2) months ago and continue daily.

Engine ceased running at 55 mph. Chain of failures- engine valve stem fractured (cylinder # 2), valve dropped into cylinder, piston struck valve, valve deformed to cylinder head, engine ceased properly detonate fuel completely, multiple codes, engine shut off. No advanced signal given to driver, no alarms when engine shut off. Power steering and power brakes ceased to work while driving in 55 mph zone, on a turn coming to a red light. Extremely dangerous for 5 occupants. Failure as shown in pictures below of the valve component are related to a material imperfection. The natural of this failure during the metal forming process was not detected for this component and will exist within other components within my vehicle or other vehicles. Once the problem is identified and corrected, engines of the effected vehicles will have to be replaced to avoid this safety issue, as it leads to potential death.
