Re: HTC One Official Car Dock suction is not sticking anymore?
Have you cleaned the suction cup, and glass? Normally this can occur for 3 reasons, 1. Suction is dry rotted (From Heat), 2. Dirty and 3. Direct Sunlight (Direct sunlight can cause the moisture to evaporate, and the hot gasses expand, causing the cup to pop off!)

3. Remove the suction cup when you exit the car, if you leave your car parked in the sunlight. Once your car cools off, then re-attach it.
Hope this helps!
