Problem is that car start without hassle when engine is cool but it wont when it becomes hot. Problem in my car has stopped since last 1 month as temp has dropped.it gave me lot of trouble in summer" It sounds almost similar.. Now in monsoon there is no issue. But issue occurs when the temperature rises. - - - Merged Post - - - Sounds similar.. Issue occurs when temperature rises.. Now in Monsoon we don't find this issue for the last 20 days. Waiting for the next time and FIAT Service ppl offered a complete detail check.. Hope the issue resolve that time..
