Cylinder 6 always presents as a misfired. Between my fiancé and I, we have 3 Escalades. After several diagnostic checks and repair bills, the lifters damaged the Cam shaft. According to the certified Cadillac mechanics, this is an ongoing problem based on the motor-??s design. This is a pretty costly repair x3 vehicles.

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.
