Reported electrical burning smell thru ventilation system. Dealership denied electrical burning but found gas puncture in plastic gas tank, says smell is from burning gas. (owner disagrees) however with no other suspension or body damage found except the gas tank puncture there is great concern that this is a serious dangerous design flaw. That the tank can be punctured so easily without the knowledge of driver of any event.

Car was stalling and shutting off. Had my daughter in the car. Couldn't start the car after 3 attempts. Then after waiting a good 3 minutes started the car and revved the engine at 4000 RPM and everything seemed back to normal. Dealer hasn't been able to duplicate.
