Intermittently, unpredictably, for several seconds at a time, the engine almost quits, especially when accelerating so far, it has not happened in heavy traffic, but if it did, it would create a possibly major safety hazard. I have not taken it to a dealer yet. Just learned about the fuel pump problem that is associated with my 2018 Toyota Avalon. Plan to contact the dealer tomorrow. I have not seen any instrumental warning or notification. There is no warning that the engine is about to lose power and so far the engine has not stopped, but recovers to normal operation. . This has been occurring over the last couple of months. I fear for my wife's safety so that she will be unable to drive this 2018 Toyota Avalon 3. 5l sedan until it is repaired.
