Highlander 6-cyl

Problems with my 2018 Toyota Highlander ([xxx]) 1 ) lane depart indicator:sometimes doesn't work until I've driven 1 or 2 or 4 miles. Sometimes in every trip stops working as well as activates when maybe a foot from lane markers on both sides of the car 2) climate control: Usually does not retain memory of fan speed, control of passenger side temp, and air flow direction when restarting the car. When temp set on, e.g. 69 temp in car is ~76-80. When airflow shows the flow aimed at windshield & feet, most of the air flow comes to my torso with minimal flow to other 2 sites. 3) need coffee break message: Has come on twice when on a long trip, disappearing after ~ a minute, but several times came on after driving only 2-4 miles. 4) faulty resumption of speed: When the speed control was set at 50 mph (once) or 60 mph (once) and I toggled the control to resume set speed the car sped up well beyond what it was set at. I had to disengage the speed controller to stop the acceleration. Happened again ~3 weeks ago when speed set at 35, and when I toggled it resume speed it roared ahead until it reached 45 mph. 5) door handle locking mechanism; not as sensitive to locking when touched as it was when car was new. Unlocking when touching handle works fine. 6) motor turnoff when at stoplight: Seldom works. When it does it turns itself off after as little as 30 seconds even tho pressure on brake pedal is constant. 8) (non-electronic problem) the transparent plastic cover over the dash control settings is deteriorating - - can?T see thru it very well in certain ways the light hits it 9) speedometer reading problem: When cruise control is working, the digital readout for the speed is usually 1-2 mph lower than what the speedometer dial says it is.

The dealer (peruzzi Toyota, 2601 bethlehem pike, hartfield, pa) was called and a diagnostic appointment was scheduled. The manufacturer was not notified of the failure.
