Hi there my smart is an 09 passion coupe and I live in Southern California's Coachella Valley Region where it gets very very very hot all summer long. My smart has been excellent to me during the season and gets noticed alot everywhere I go. The problem is it has stalled on me once last summer and twice the summer before both on extremely hot days and my nearest center is in Riverside which is one 1 hour away from home. I have taken the car there regarding this issue and have been told that there was nothing wrong with the car. So my question is what tips would you have so I could prevent my smart from stalling on me again and especially this coming summer??
