Got a Glow plug warning this morning. This is the fourth time I have got it in the last 1 year or so. Hopefully it is not a plug that I replaced recently. This got me thinking if this warning appears for some folks sooner than others due to driving habits. Today morning, my car came to a halt just as the light turned green on a traffic signal. The A/C was running as well as the ICE. I turned off the ignition without turning off the AC or the ICE. Immediately I noticed the glow plug warning. I don't do this often but wonder if that triggered the glow plug to short. My battery is fairly new (just over a year old). Have others had such an issue?
