Exterior Lighting problem #1

As the vehicle was traveling on a highway at 35 mph the vehicle shut off electronically three times and powered itself back on after 15 seconds or so of continuous cruising on the highway. Unable to accelerate or control the vehicle while the electronic component shut off in the vehicle. Three days later, a series of warning lights and check engine lights turned on, which has occurred 6 other times, and has been brought to local Toyota dealer multiple times (over six times) and no fix has been conducted to repair the vehicle other than resetting the vehicles ecu. When all of the warning lights turn on, the vehicle loses 2nd gear and juts itself forward and becomes extremely difficult to control to the point where I have almost gotten into life threatening accidents over 4 times. Toyota has acknowledged that they do not know what is wrong with the vehicle and is unsure how to fix it. This is a safety concern that is not getting enough attention and needs to be rectified before someone or myself ends up killing ourselves.

Exterior Lighting problem #2

When carrying cargo, the cutoff of the led low beam headlamps is shifted upward blinding on coming traffic and dazzling other drivers. This requires the driver to manually adjust the angle of headlight projection under the hood of the vehicle, as there is not automatic system to do so, or even a manual system inside the vehicle. As a result, it’s likely few drivers will do this. Also, it is not possible to manually adjust the headlamps every time the weight in the vehicle shifts. Leds are particularly bright and affect oncoming traffic. If they are not perfectly aligned at least 50% of the oncoming cars flash their lights at me, many leaving their brights on, probably assuming I am doing the same. Therefore, it’s not just that my vehicle is blinding them, but there is also an element of road rage that comes into play with both drivers becoming dazzled. As such, basic visibility safety at night, should require led headlamps to all have a self-leveling feature to account for the headlight cutoff angle changing when carrying cargo.
