2019 Toyota Highlander Vehicle speed control Problems

“A month ago, we were driving on the highway through snow showers up to nh to go skiing, with our nifty adaptive cruise control on, when I realized that we were accelerating into the car in front of us. I assumed that the front sensor was covered in slush, took off the cruise control and drove manually. Only about 5 minutes later did the dashboard alert notify me that the front sensor wasn't working. Brought it into the dealer. They couldn't find anything wrong. Here's the problem: the car says trust me. …”

“Severe hesitation when gas is applied, especially when crossing heavy traffic and instant power/quick acceleration needed. Also noted when going around corners, after car has slowed down below 5 MPH to make the corner. Gas is applied with hesitation. Noted more when car is at a complete stand still/moving at slow speed then gas applied to move forward. Car does not move/react instantly. I notice this problem on a weekly (at least) basis.”

“Vehicle is slow to respond and/or has intermittent performance when accelerating or moving from complete stop. There is lag time in the vehicle's response to driver acceleration which makes it challenging to enter (from roadway or driveway) oncoming traffic or merge into interstate/freeway traffic. The delay in the responsiveness and inconsistent performance causes driver to need extra time and distance when entering the flow of traffic. The front end also becomes jumpy and enters with a skid/pull force causing the need to steer into the vehicle and course-correct. …”

“I had just driven up a steep driveway and made a slightly sharper than 90 degree turn at a very low speed to pull into a home parking spot when the car lunged forward suddenly and slammed into the stone wall of the house at a high speed. The section of this driveway after the turn is only 2.5 car lengths, but the car picked up enough speed to smash the front of the car in. The car was totaled and driver and side curtain airbags all deployed. I do not know why this happened as there is no way I would have hit the gas hard while pulling up to a building to stop. …”

“Problems: 1) Check Engine Light lit up. 2) Hybrid System Malfunction warning on heads-up display. 3) Pre-Collision System Failure warning on Heads-Up Display. 4) Gasoline engine stalls after an intentional deceleration and is unable to come back up to speed. First Event: On July 4th, my wife and I were driving on an interstate highway. We entered an exit ramp interchange to merge onto another highway and when trying to accelerate the car suddenly became sluggish, and gave messages for problems 1), 2), and 4) stated above. Problem 3) did not occur during this event. …”
