Fe Rider

I got my santy 3 months back and i have been having the indicator not
go off when my wife (105 lbs) gets on 1 out of 4 times at least.
However after switching off ignition and starting it up again it goes
ALWAYS goes off.

I gave it for a checkup to my dealer but they didnt have an answer and
hinted a recall is due as it was in elantra. they also pointed that it
could be my wife's small frame that might make it irregular. I am not
sure i accept that as my argument is how come the sensors can tell on
retstart but cant tell on run. then its not a weight issue.

I intend to test this with a more 'appropriate' weighing buddy to be
100% on my argument.

Has anyone had any similar problem or have workarounds as i am
concerned over the safety with summer highway drives approaching ?
