Example complaints

Seats: “When I am using my ventilated seats the bottom of the seat is cool and feels good but the back upper portion near shoulder blades feels like its being heated. I have the cold air on in the car and the cold air on in the seats and I can have both at maximum cool and it will still heat up. Worse is that it is random but has been occurring on other cars too as seen in forums. When you turn the cooling seats off it will cool down and when you turn them back on then it will heat up again.”

NHTSA complaint #10761786, filed 2015-09, 600 miles

Electrical system: “When I'm using my ventilated seats the bottom of the seat is nice and cool but it feels like the my back is being heated. I always have ventilation on lowest setting. The top of the seat between shoulder blades... Very hot!??? Seriously. I felt it with my hand, as if the ventilation was shorting the heating elements. It stayed hot a while after I turned off ventilation. Then it cooled. Had this happen to me on my way home. The bottom of the seat was cooling but mid back the seat got very hot. Turning it off did cut the heat and then it would come right back when I turned it on. …”

NHTSA complaint #10748834, filed 2015-08, 3,500 miles

Exterior lighting: “Nothing took place that resulted in the following electrical behavior to occur....the left rear brake light blinks as if it has some sort of an electrical short; then after a couple days of on-going blinking,it has completely went out. Ultimately, the left side brake light is completely out which is dangerous (illegal) to drive with out it.”
