I've had mine on for a few years now. Got the cut out from Summit and had issues with the first 3. each time Summit sent me new ones no questions asked. I got very quick at changing them out. took a few apart and saw a lot of carbon and rust build up along the bearings and travel path. I started spraying down the gate and path (in both the open and closed position) with WD40 about every 2 or 3 weeks (takes 30 seconds) Seems to work awesome. Keeps the gate and travel path clean. I spray around the motor also so that may be helping. Another thing i learned was as soon as the tone changes when you open or close the gate, stop! The motors aren't very strong, and don't stop automatically once fully open or closed. The motor continues to run as long as you hold the button. I think this may be causing a lot of the issues you read about with the valve. Once i stared doing all that, it's been great! No rattle and perfect for when I leave for work early in the morning, or if the wife is in the track for long trips. You look under the truck, and everything associated with the valve (valve, Y pipe, and turn down) look brand new because its stainless. The stock pipes are already rusting though. All in all, one or my favorite mods.
