garage door openers




I posted about this a while back, but had not been told M-B is aware of the problem at that time.
Mine sticks as it comes back out and signals the door a second time. This causes door to stop in mid-opening/closing.
Worried that even if I wait for door to fully open and then drive in, button will send another signal and door comes down on car.
BTW, never have a problem with my other cars or with cars I have owned before-both those with Homelink and using regular door opener.
Probably only use the buttons 3 or 4 times per week, so it is not normal wear.
In addition, since 1982, doors need to have a mechanism in place to prevent closing if something is in the way. The sensors are always placed a few inches off the ground and the only part of a car that would activate this safety device are the wheels, so a door could easily close on a car halway into the garage.
