Osama, my wife, lost confidence in our Sig P85 the first week we brought it home in 2012...it wasn't a car related incident that caused this, (it was charge anxiety...winter time, and our electrician failed to install our HWPC in time for the Model S's arrival...hence, we could not recoup range fast enough on 110V...this resulted in her having to drive to a charge site, leave the vehicle there for about 5 hours (32 amp) to get "just enough range" in the battery to get to work and back...around 11:00 pm each night, we drove down to pick up the car and plug it in at our house at 110v so she could use it in the morning...we had to do this for about a week...total PITA (she was seriously thinking that we had made a mistake buying this vehicle!)...it caused her to lose total faith in the car's ability to get her back and forth to work safely (55 km 1 way to work).
The bottom line is, she gave the car another chance (and was patient enough to agree to measure the car's 'fitness") based on when we could properly charge on our HWPC at our house.
She now has over 50,000 electric (Tesla) kms under her belt, and couldn't be happier!
I have over 100,000 electric (Tesla) kms driven, and assure you that although ANY man-made product can break down (and usually at the worst time...see Murphy's law), Tesla makes good products and services them well.
No one likes a product failure to let them down...when it does happen, it is generally just bad luck...I urge you to speak with your wife and see if you can get her to see her way clear to giving the car another chance...based on my / my wife's experience, she won't regret it.
Cheers!
