“On october 15th at approximately 3:30 pm (ct) my 2014 Toyota Sienna was parked in my driveway with the engine on, unattended, when it moved forward up the slight incline of my driveway, struck another vehicle that was parked in the garage and kept moving forward until it struck the front wall of the garage. Prior to the accident, I had reversed the van out of the garage and left the van ignition on and in park as I exited. …”

“All of the sudden, after a long drive on highway, I parked and fuel my car and my car would not change gears properly or very sudden burst then stuck in gear, then after little while I stop on the side and now it won't drive or reverse or sometimes won't go park.”

NHTSA complaint #11155534, filed 2018-12, 105,000 miles

“9545 moores point place I was driving out of the parking lot from the grocery store, I stopped to enter onto route 301 making a right turn on to the road when the van accelerated, it was all I could do with all of my weight on the brakes to stop the car from hitting another car. It was frightening.”

NHTSA complaint #10730461, filed 2015-06, 21,000 miles

“With the hood open with prop rod installed, I pushed down slightly on the hood and it crumpled like thin flimsy metal at the point where the rod connects to the hood. I am not strong - 6'2'' and only 175 pounds. Now the hood has a bend and cosmetic damage at the crumble point.”

NHTSA complaint #10747985, filed 2015-08, 23,100 miles

“At right around 50,000 miles, the cable on one of my power sliding doors snapped. This I have already filed a complaint for. But then at around 52,000 miles, the cable on the other power sliding door snapped. Now both doors have to be used manually, which would be fine except for the doors are so incredibly heavy that if the car is on any sort of hill, my children can barely get the doors open because they are so heavy. On top of that, they don't always lock open when being used manually. …”
