Your trying to rationalize something you don't understand. A failed lifter can absolutely cause a vehicle to stall out and shut off. Do you understand what a lifter does? If it was a common occurrence it would have been recalled. The previous generation has more lifter issues then the current.Very few of these Tahoe, Yukon, Escalade owners are on this forum compared to vehicles sold. Vehicle problems on forum is not the best gage for number of problems a manufacture is having.
From reading threads these lifter problems are miss and noise and as per TSB ": Engine Misfire/Tick Noise, Malfunction Indicator Lamp (MIL) Illuminated - DTC P0300 Set" Doesn't say engine shuts off.
A bad lifter can cause safety issues. If you drop a lifter/lifters at 75mph it becomes a safety issue. The reason there is no recall is because it does not affect enough vehicles.A bad lifter or two will not stop an engine. It will bother performance, And I definitely know what a lifter does and works.
Is this from my statement on recalls are for safety issues.
My information is from reading articles and personal information, here is link to article that lifter issue is not a "safety issue."
