I was going to make a right turn and the car would not accelerate right away even though it was in "D" my husband said he experienced the same thing twice while driving this car.

The contact owns a 2017 Toyota Prius. While the vehicle was parked, it rolled without warning. The contact was able to catch up with the vehicle before it struck a police vehicle. The officer gave the contact a warning. In addition, the vehicle accelerated on its own intermittently. The local dealer (elmore Toyota, 15300 beach blvd, westminister, ca, 92683) informed the contact that the vehicle was not included in NHTSA campaign number: 16V741000 (service brakes), and recommended he schedule an appointment for diagnostic testing. The vehicle was not diagnosed due to the diagnostic fee. The manufacturer was contacted and provided case number: 1709193209. The manufacturer confirmed that the vehicle was not included in the recall, and that there would be a diagnostic charge. The failure mileage was approximately 15,000.

My new Tacoma has a whine/howl coming from the rear differential. Per my dealer, they have started a tas case with Toyota Corp and were advised that the condition described is known, and under investigation. Tas says there are no recommended repairs at this time. The problem is occurring between 30-65 mph when decelerating and feathering the throttle, but is now becoming more pronounce with time and more mileage. I'm concerned that the issue could potentially become a safety issue. This issue is occurring with 2016-17 Tacoma's. many differentials have been replaced by dealers; even the replacement differentials are experiencing the same issue.
