I had a 2019 Highlander that had this problem. I had 3 incidents in February 2020. The first was while drive at 60 mph on a rural road in Central Texas. The engine suddenly stalled, and I had to pull over on the shoulder. After a few minutes of wondering what's wrong I turned off the engine and restarted. It was ok for about a week or so. Then while drive in city traffic at slower speed the engine stalled and hesitated. I just slowed down and that solved the problem. The 3rd incident was about 2 weeks later. I was in rush hour traffic on a city street. I stopped for a light. When the light changed the engine stalled and I could not accelerate as fast as the cars around me. I limped into the outside lane and into a parking lot. It took about 5 minutes to get the fuel pump working again this time. So I took it to the dealership. The car only had 20,000 miles on it. The dealership listened to my problem and said I could not drive the car in that condition because it would not be safe. The gave me a loaner, impounded my highlander, and said wait for a pending safety recall in which Toyota would have a repair. Toyota paid for the loaner and will pay for the repair. I waited 6 weeks, but my Highlander was never repaired. Toyota sent out an official safety recall in March that recognized the problem with the low pressure fuel pump. However, they did not have a solution yet and gave no date when it would be repaired. There are 1.2 million Toyotas subject to this recall. I didn't think I would ever get my Highlander back. I wasn't sure that Toyota had solved the problem or if they ever would. So I traded it in for a year 2020 RAV4. Now I'm happy that I am back in an SUV which sits higher on the road than the Camry loaner I was driving temporarly.
