When we are driving our Toyota 2010 Highlander if you hit a bump the door ajar light comes on even though the doors are not opem. We are not able to use the sunroof or open the windows because the door ajar light comes on and the interior light and the beeping for a door open. This is very disttacting when trying to drive. It is getting worse now every time we make a turn ot go over the slighest bump the light comes on and the dinging for the door starts Toyota really needs to fix this! it happens all the time when we drive our car'

Faulty rear door ajar sensor reports rear door open intermittently while door is closed causing interior lights, warning lights, and chimes. Started with only turns, acceleration, deceleration, but rapidly deteriorated to near constant failure, particularly in warm weather. Initially started near 2 years ago (25K miles), but was only mildly irritating. Now vehicle cannot be locked with this condition.

The back up lights on my Highlander are almost non existent. I have tried to use them to back up at night and there is not light at all. You can barely see anything at night using these "back up lights" I feel this is a safety hazard. I live out in the country and need these back up lights to see any obstruction at night. I took the Highlander to my mechanic and he said that was just how Toyota made these back up lights. I feel this is insufficient and dangerous when trying to back out of my drive way at night. I cannot believe no one has addressed this problem.

When stationary or driving, dashboard door-open light stays on. All dome lights stay on when driving unless turned completely off on dashboard but they will still flicker and warning sound will go on and off when driving, turning a corner, or going over a bump on any road. When locking the car with the door-remote, the warning sound goes on and stays on until car is unlocked. Car must be locked by hand to stop warning sound. Car was sent to Toyota repair center for electrical repairs, but this warning light issue was not repaired. There is a bump in the rear hatch from backing up in a garage. Service dept. Said rear door needed to be repaired because rear hatch would not close correctly. However, rear hatch has always closed and still closed. Toyota could not guarantee a new hatch or repaired body work would fix the problem. Warning lights problem started months before rear door issue. Toyota offered to turn warning sound off, but I feel it is a safety issue. I routinely checked if any door is open.
