I have a 2008 G6 and for about a 1 1/2 months have been having to inflate my rear drivers side tire about every 1-2 weeks because it has a slow leak. Now 2 days ago my radio display showed Service Tire Monitor and my check tire display on my dashboard stays lit. Does anyone know if there is a Technical Service Bulletin or Service Notice (maybe they're the same thing lol!) for this problem? I found a little information about a TSB for this problem on another site, but there wasn't much information given, it just said 08-03-10-006C APR 10 Tires/Wheels - Tire Slowly Goes Flat/Warning Light ON. Could the monitor be the cause of my tire losing air? Checked the NTSB website and couldn't find any information on there about potential notices either. Car had 6k miles when I purchased it in 2008, now I'm just a little past 76k.
