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.

Turned corner in large center city and hit a construction large pot hole and/or obstruction on the left rear. After completing turn onto a narrow one-way street acceleration increased, brakes did not work, engine could not be turned off, gears could not move. After going through two major intersections without accident I kept pulling on the emergency brake. The car slowly stopped and was then perfectly normal. Could use the brakes, shift, etc. I parked overnight in a garage. Had the car towed to dealer the next day (7/21/12), where it is still unresolved. Dealer said car is ok, but is now being analyzed by Acura corporate engineers. I had three other people who were in the car at the time, including my wife, who will not ever go into this car. The car was only 10 days after purchasing.
