With the onset of cold weather, the button on the gear shift handle is very difficult to push down in the a.m. and so it is a struggle to get car out of park. Also with cold weather key intermittantly sticking in ignition. Took to service, recommended to get a new gear shift handle. Same problem. Next service gusy cleaned out the console surrounding the gear shift. they thought coffee had been spilled. Same problem. Any ideas out there?
