I have had my model s for almost 3 months. Love the car. Trouble is, it's been in the shop now three times. Twice it was in for 12v battery issues, which I understand is pretty common. The last time (currently - 2 weeks) is because a faulty seal on the windshield which caused water to slowly leak over time, which then affected a wiring harness. My wife is very unhappy with the car. Her chief concern is that it is unreliable and fears we will get stranded somewhere. She wants me to return it. I confess that my own confidence in the vehicle has been shaken. For now, there's an easy way out...the happiness guarantee. I've spoken with the sales team and they say I can invoke the clause and move on. I have until Friday to decide...after that, the car is mine for good. My car was manufactured at the very end of 2015, when there was a big push by Tesla to meet 4Q targets. One of the sales reps actually suggested it might be a "lemon", which is not a great word to use around a new car owner who just spent almost $120, 000 on a vehicle. And I've read some horror stories about a few who have had persistent problems with their vehicles....it seems there are cars that are prone to failures. I have yet to read of anyone actually using the "Happiness Guarantee" and returning their Tesla. Anyone? Anyone have what they would call a "lemon" that they regret not returning when they had the chance?
