I think there is an issue lurking here somewhere...why all of a sudden are so many individuals experiencing possible sensor issues ?..I still get random start up alerts...sometime they go away..the first time I thought I had it narrow to a front middle sensor...then after unplugging it it went away..I did a general reset and plugged it in and all was good until I had to do the same thing with a rear...then all worked for a few days and today I got an error and rebooted 3 time and it went away...something is not adding up here..
