Hi Guys,
Really it's a problem. Here is my saga with my path 2006. During the first winter 2006-2007 i had this experience too. Twice time minimum. The battery was so down that i could't start the car. And some of my electronics fileds was reseted to zero.
I spoke to the garage about this and they seem didn't believe me about this.
The asked me to keep the car until it do it again with a weather below 25-30C . But the waether coming warmer. So for this first year it was to late and for the warranty replacement too ( Bought new during summer06).
Whinter 2007-08, PAth still at the hotel 2 weeks. AS came back. Battery down another time. went to Qc Garage and change the battery and PAID for that.
Winter 2008-09. During holiday, car till 1 week. AGAIN the battery was so down that it didn't start again. NOTE that it was plugged all night.
2 weeks ago, I went to the dealer to check the car. TEst WAS without any problems ???? NOW i tried to resolved it with NISSAN.
DO you have some suggest? IT SEEM A REAL PROBLEM FOR THIS PATH"
