Engine Shut Off Without Warning problems of the 2012 Acura TL

On 7/20/2017, I was driving on I-680 s towards fremont CA. I was driving roughly 70 mph. When I was about to pass a car, all of a sudden, the engine lost power. I hit the gas paddle all the way down, and it didn't work. As I felt a significant loss of power, I pull over to the side and stopped the vehicle. The engine shut down immediately when I came to a complete stop. I tried to restart my car, but it does not work, and the engine check light popped up. I had my insurance towed my car to oakland Acura, as I did an oil change there on 7/19/2017. After an inspection, oakland Acura indicated that the intake and exhaust valve does not open and close normally. A value adjustment will solve the problem. I felt that it's pretty impossible for all the valves to be malfunction all at once. Thus, I asked the technician are all the valves malfunctioning, the technician said should be. I then asked whether such a problem is caused by an improper oil change since they did my oil change the day before, and I only drove 25 miles after the oli change. The technician said, "I don't think so". I further asked whether it's an engine design problem that is subject to a recall, the technician commented that these engines last forever. Thus, they did a valve adjustment for me, even though I don't know what they really did. I got charged for $499 for this valve adjustment. I also noticed that when I started my engine (especially in cold weather), my car has a bubbling noise. I noticed that on many Acura forum, many Acura Tl owners have the same problem. I asked oakland Acura to look into this. The conclusion they gave me was inconclusive. I want to report this issue because it was really dangerous that an engine lost power completely on a high way. I am not sure if it's an engine design problem or not, so I thought I should report this.
