The vehicle hesitates and stutters upon light to moderate acceleration. This can happen either from a dead stop or while moving in traffic. The concern was present when vehicle was purchased new in Feb 2023. Initially the dealership thought the symptoms were related to the transmission learning algorithm, but this was later determined not to be the case and the dealership was able to reproduce the drivability concern. The dealership was also advised that running 91 octane fuel eliminated the symptoms, however the engine is designed to run on 87 octane. Subsequently, the dealership was advised by Toyota to replace several parts associated with the VVT (variable valve timing) on the exhaust camshaft which did not resolve the concern. Toyota subsequently agreed to replace the vehicle after filing a lemon law complaint with NCDS. This drivability concern is a safety concern as the hesitation and stutter could occur during a traffic maneuver and cause an accident due to the engine not properly responding to driver input. No check engine or other warning lamps present when this occurs, which is most of the time though more pronounced when ambient temperatures are above 75F degrees.
