So, my wife and I have had two bad experiences with our 2017 Model S 90D and have had it only since the first week of July and have put around 5k miles on it.
First issue was warnings on the dash that something was wrong, needed service, and power was reduced (Tesla termed it 'limp mode') midway on a road trip from NYC to Boston for a weekend. We were advised to either 1) Call for a tow or 2) try to get it to our home dealership in Brooklyn, since we were over 100 miles away from home and the nearest dealership was in Connecticut where it would be serviced.
It took 13 days, but eventually had the front Drive Unit replaced because the warnings were due to a failing front Drive Unit.
This past weekend, we were on our way back home (from Connecticut again, maybe we should avoid the state) and halfway across the Henry Hudson bridge when all of a sudden the car lurched forward and 6 error messages appeared on the screen, all at once.
Park Assist Unavailable
12V Power Low - Car May Shut Down Unexpectedly
Unable to Drive - PULL OVER SAFELY
Car Needs Service - Car May Not Restart
Car Needs Service - Unable To Start Car
Car Needs Service - Contact Tesla Service
Thankfully we had enough speed that we were able coast down the bridge and pull over. In addition, on the dash, PRND were all marked red. We called Tesla Roadside, and while on the phone with them, the 12V auxiliary battery shut down and everything went black. 3 hours and 3 tow trucks later, as no one could figure a way to get it into tow mode, we finally found one that was willing to flat bed it (I believe he dragged it, wheels locked) to the nearest dealership in Paramus, NJ. Super fun.
Anyways, just got a text from Tesla saying "we have ordered a new front DU for your model S, we'll update you when we have an ETA".
My question is, shouldn't they be looking into a root cause for our car causing a failing front DU warning and then, after replacement another one that catastrophically failed and left us stranded? Obviously something is causing these to fail on OUR car with < 5k miles and there might be something deeper in this vehicle that's causing them to fail so often?
Anyone else have multiple front DU failures on a (relatively) new Model S? The first replacement took 13 days, if this one takes nearly as long, we're approaching the 30-day lemon law in NY. Should we be talking to Tesla about a possible replacement? We are really concerned with the reliability of this particular vehicle and will have a hard time trusting it frmo now on.
