My warning light/sound goes off at least once every week since I bought my '04 G35. I called the dealer & they recommended raising the cold pressure to 32PSI all around. I followed their advice. I check it weekly. Today my warning went off again. It happened first thing this morning (I know that is the coldest time). I live in So Cal. The OS temp was about 40.
Does anyone else have similar problem? How do I know if it is a faulty sensor & which rim? I have stock tires & rims & don't overload car (2 small kids in the morn). Maybe I have a slow leak in a tire?
