So I just got a '12 Ram Crew cab a couple of weeks ago, and just had an issue with it today. When using the remote start that the dealership put in when I got in the truck and placed the key to "on" I would receive a message saying low tire, and went away. I checked my tire pressure and everything was fine. Last night I was driving home and the light came on and stayed on this time. I went into the dealership today and the light was still on. When I went to service the lady just repeated over and over to check the tire pressure. Finally she got someone to look at it and he checked everything out and he couldn't find out the issue, but because I am getting them to install new rims this week on the same tires they were going to make sure that everything was working when it left the next time. Later today the light went off, so I don't know what the issue could be but just letting everyone know to keep an eye out for this.
