Service network is not good or not geared enough. I discovered a unique problem with my nano. I didn’t start nano for 3 consecutive days and tried to start it on the 4th day. I noticed the battery is discharged completely by itself. No clue, called the breakdown assistance and charged it. It was very painful for me to get it re-charged every time by calling break down assistance. Though the break down assistance service is good, But no body able to solve my actual problem. So far I have used breakdown assistance thrice and thrice sent my vehicle back to service station in last 2 months.
