My Mazdas car tire wlwas leaking Eric, and it was time for an oil change anyway. So I scheduled an appointment and they were able to get me in that very afternoon. I waited about an hour and a half and then was given back my freshly car washed car. I noted the dash light for check tire pressure was still on, the service professional told me it should turn off every couple of miles. About 25 miles later when I returned home, the light was still on. in the morning, my husband checked the tire pressure and it was down to 18 lb. I returned to the dealership and was given a loner. The service folks are very nice and we're truly apologetic. I have had to deal with Nails in tires for decades. This is the first time a plug has ever not help. I am wondering if the mechanics thought it was done, but head only aired it up and forgot to put the patch on. We were able to return the loaner the next day and go back to driving our own vehicle.
