Very early yesterday morning while I was shopping at Acme my Element was parked in the cold parking lot. When I started up the vehichle and pulled away I heard a loud clicking noise That only lasted for a couple of seconds that sounded like the speedometer cable might need lubrication. After the engine warmed up it stopped. It also made the same noise in neutral when pushing on the accelerator pedal as the RPM's were coming down. I park in a heated garage every night. So early this morning I took it to the dealer and let it sit outside for an hour but it would not make the noise again. It seems that whatever it was needed to adjust to the weather change. I called the parts department and they informed me that there is no spedometer cable on this vehichle. It is completely electronic. Does anyone have any ideas what could have been causing the noise?
