Battery Failure
 Be aware that something is draining the battery on high end Nissans faster than the charging system can recharge unless you drive it on a regular basis for at least 15-30 minutes. Suggest staying away from Nissans if retired or you do little driving. Know of three new Nissans two 2009 Altima and one 2010 Maxima where battery has failed within 30 days after purchase. My uncle's has failed three times even after a new battery was installed. Mine has failed twice. Would get rid of it but don't want to take the financial hit.  Joined AAA.
