The gear shift when placed in park and the car ignition turned off would cause an alarm to go off and a message to show up on the dash that the gear shift should be placed in parks (which it was in already). When I contacted the GM in CA dealer and talked to him he advised me it was a common problem and the was a shortage of parts to repair but bring it in because the alarm would where down the battery. After jamming the gear shift in park many times I was able to stop the alarm. Them I drove from CA to NV to the Buick dealer there and told me the same thing that the GM dealer tome about a shortage of parts because of this being a common problem and that he would try and get GM to pay for repairs. When I picked up the car I was advised that although this was a common problem GM was not going to be a recall so I had to pay the $558.40 to repair the gear shift. The recipt shows: ‘SHIFT CONTROL ASSEMBLY REPLACEMENT — found intermittent failure to register shifter position of park — Need to replace shifter assembly ‘
