“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”
“Vehicle has extremely poor acceleration from a stop. It is very dangerous when pulling out into traffic as acceleration falls flat for a second or two until it eventually responds and accelerates”
“My new Highlander has had issues that I can describe as "power surging" when accelerating from a stop. The car frequently does not respond to accelerator being pushed down for a second or two and then surges from a stop to accelerating with very inconsistent results”
