Problems with 2013 Toyota Highlander EXTERIOR LIGHTING

When i turn the signal left both flashers blinks. when i turn the signal right both flashers blinks. i checked hazards light button and it is not pressed. both signals flashers are blinking at same time.

The door open alert and alert beeping came on as well as all of the interior lighting as i was driving. it shows glass door on the display. i checked all doors and none of the doors are open. it was very distracting and dangerous to be driving at night on the highway with all interior lights on. they keep going on and off and the alert keeps beeping. as far as i can find out, there is no way to turn off the interior lights. my car is out of warranty by 300 miles. i just had it in for the 35,000 mile service. i find numerous accounts of this known issue on several websites/discussion forums. i called toyota and was informed there is no recall however i found there was a tsb? sent out on the back latches. i called jim norton toyota in tulsa, ok and was informed they want a $110 diagnostic fee to see what the issue is. seems like with all of the same issues that toyota would look into this issue and resolve. toyota said they could not waive the diagnostic fee. hoping i can find a quick fix or someone willing to resolve this issue inexpensively or better yet, toyota could step up and resolve the issue themselves as a customer service stand. *tr

When the headlights are on dim, visibility is not adequate. a distinct black line appears across the horizon above which the driver cannot see. *tr

Tl* the contact owns a 2013 toyota highlander. the contact stated that while driving 55 mph, the vehicle suddenly stalled. also, the contact mentioned that the headlights and instrument panel light intermittently failed. the vehicle was taken to the dealer. the technician was unable to duplicate the failure. the manufacturer was made aware of the failure. the vehicle was not repaired. the failure and current mileage was 16,000.

I purchased the toyota highlander in december of 2012. immediately we knew something was wrong with the headlights. they are focused down toward the road and have a line of "shade" above. the highlander lights are so dim, we don't know if they are working. we are "overdriving" our visibility at night and we cannot see any road signs because the lights are focused to far down they do not illuminate signs on the side of the road. in addition, in hilly areas, they only illuminate the bottom of the hill (and the shaded part is above) so you cannot see where you are headed.the tops of the hills are completely blocked by the "shaded" part. this is a very dangerous situation! also, they do not get warm, so the snow and ice accumulates on these lights and obscures visibility even further! i have owned many many cars, including several toyota's and have never had a headlight problem. i do not know what to do with this car as i cannot drive it at night. *tr
