It takes time to accelerate. The car jerks and shakes before moving
I have a 2023 Toyota Highlander Platinum. For some unknown reason, the dashboard suddenly stopped working. Because the dashboard is not working, I have no information on things like when the gas will run out, what speed I’m driving, or if any parts are malfunctioning. This creates a dangerous situation for me. So, I went directly to Toyota and had the car inspected. They confirmed that the dashboard was indeed not working. I have the document from Toyota. Before the issue occurred, there were no warning signals or alerts, it just went completely blank. I want to drive my car calmly and safely without any worries. Please help me with this.
The vehicle has erratic acceleration. It will either be extremely slow and jerky or it will jump forward with great speed and force. This is dangerous and may cause an accident. You have no control when it comes to acceleration whether you are leaving a stop light or trying to avoid an accident.
Hesitation/Non-linear Acceleration From a Stop. Reprogramming the ECM completely resolved the issue. This needs to be sent out to affected vehicles but I had to investigate and pretty much demand a resolution. I fear what this could later do to our engines, etc.
When 87 fuel is put into the vehicle, the 2023 highlander is jerky/has hesitation, RPMs jump around. Trying to slow down to a yield then go again it jerks and almost feels like engine is cutting out. Seems worse when car is being driven on warm day with a/c on or under a “load”. Very dangerous in intersections. Current fix is to put 93 octane in the vehicle to remedy the issue. Putting 93 octane fuel in the vehicle does help. All of these issues pose a risk to the car jumping from a start to cause a rear-end accident. I've complained to the dealer and they've stated everything is normal when they test drive and no codes are showing even explaining a TSB was issued they refuse to fix. Started at 500 miles on odometer, still happening at over 13,000 miles.
