Warning: This is a long one!
I hate to say it, as usual, being pretty much Tesla's biggest fanboy.....
I would have to rate my car as becoming LESS reliable as time goes on. With each "new" (or reman) drive unit, the failures are coming quicker. I'm getting my 4th DU in 2 weeks. I've gone through a battery, a number of door handles, cooling fan, coolant pumps, active shutters, endless water leaking into my trunk (not just the hatch any more, when my car goes in for the next drive unit, I believe my hatch and taillights will be resealed for the 15th or 16th time, and water is now pouring into the car every major rain storm, as well as hatch fills up every minor rain shower), charge ports, Endless Key Not In vehicle with no resolution in sight. Broken ball joint at ~52,000 miles. Both front sway bars at ~68,000 miles. On third set of tires because of excessive, un-correctable negative camber on rear tires, and a seriously bad alignment job from factory when the car was new taking about 12,000 miles of life off the original set of tires (based on my second sets live span to get to the same tread depth). Seat motors popping apart, UMC failures, squeaks, rattles and more.
I could continue, on and on and on and on, but so far, the total number of pages of service records is about 120 most likely more as I have not added the most recent ones into the mix, and I estimate if I had paid for repairs out of pocket (not counting the upcoming visit for the Drive unit, Sealing the trunk yet again for water, 2 more door handles acting up and now my drivers window) to be somewhere between $100k and $150k based on what out of warranty replacement service has cost other members here. (As usual, I feel the need to praise Tesla's service centers for a awesome job. They are not at fault for any issues.
Frustration has built up to the point where, if I was any less of a man, I would have driven the car through the Tesla showroom window (Chinese guy with the sledge hammer comes to mind), but since the major failures happened outside of the first year of ownership, lemon law doesn't apply.
In conclusion to my rant, Early production cars seem to fall into one of two categories. Category 1: A few issues here or their, spread out, of the minor fairly minor type. Category 2: Endless issues, of all types, both making the vehicle inoperable at times, and endless nuisance issues that keep re-occurring.
I had planned on keeping my car for a fairly long time (8 years minimum). I had hoped that I would be handing my car down to my Geno when he turns 16, and then upgrade to Tesla & Elons Rocket Ship Interstellar version. However, at the reliability level of my vehicle, I dread when my odometer ticks over 100,000 miles in December or January, as I know if I have a large failure not related to drive unit or battery, my car will need to sit as a paperweight in my driveway until I can afford the repair. It's sad and sickening at the same time.
Because of the above, and the number of referrals I have gotten in the referral program (16 now and a few more potentially within the next 6 days), that is some nice credit, that I could use as a "extended warranty" option to pay for repairs when the ESA expires.
I also thought, since I have more then 10 referrals, I could even get a Model X loaded for the cost of a base model (Rumored to cost only about 5k more then a base Model S). Which POTENTIALLY might have been do-able, if I sell or trade in my car, as well as use all my referral credits I have left, and take out another loan.
Now I must ask myself, though, what is my car worth??? I am a straightforward honest person, so for starters, If I sell it private party, what would the buyer ask me? Well, first thing they will ask, has it been reliable. I can not, and will not lie, as I pull out the Ream of Papers that is the service records of my car. How much value has my car lost because of that? Next, trade in, how much is my car worth? When I inquired the last time, I was straight out told pretty much nothing to tesla. $1 per mile deduction, and deduction for age brings the value of my car at about 10k to tesla after only 2 years of ownership, endless headaches, problems, getting stuck on the side of the free once due to a battery contactor failure, the car going funky one cold slick evening ending up with the car deciding to disable power steering, abs, and more on a nice slick road almost causing me to end up in a lake.
Once you factor in everything, Service records and Issues, Mileage, old age according to Tesla, Then you have the loss of value because it's not a Dual Motor or Autopilot hardware car, then again, another drop in value after the consumer reports fiasco (And hate me all you want, I believe that Consumer Reports was dead on with reliability based on !!!MY!!! experiences, at least with the First Gen "CLASSIC" Model S cars), my 2 year old Model S is now worth the same or less then my old, beat up 13 year old Nissan Xterra. Obviously, I am playing on the extreme for private party. I'm sure private party I might squeeze 20 or 30k out of it, I'd be better actually parting it out.
After saying all of that, you may ask, why would I want another Tesla? Well, because in general, they are learning from past mistakes. And they are showing that they are improving things, raising the bar on quality. I have seen and experienced it first hand. The progression over time. Not just in the endless number of brand spanking new (and sometimes New, but WELL WORN) loaners, but also in other road warriors such as myself that have newer "Second Gen" Model S Cars (AP Versions). I rate quality improvements in just 2 year 5 months that I've been a owner, the improvement has been over 1000%. It's impressive. It's also unfortunate that some of us have had to go beyond being guinea pig alpha testers. I'm not a litigious person. I suppose if I was, I'd have either a full refund by now or a brand new car sitting in my driveway. But alas, I do what I can to make things work. Couldn't afford the lawyers if I wanted to. And if I lost, heck, It would bankrupt me (The only people who win a in lawsuits are the lawyers no matter what the outcome!).
So that ends my rant and opinion piece. I'm sure my phone will be ringing from Tesla tomorrow morning. They most likely have me on speed dial by now. But if you haven't seen it in this post, look again. My feedback is honest. I am well known for being Brutally honest. I show both sides, good and bad. I am straight forward, I don't sugar-coat things. If Tesla doesn't get feedback, they cannot improve. Maybe I am a rare case, but the number of "classic" owners having repeat issues and bugs that just cant be squashed is much higher then it should be at this point.
And in closing, I will repeat. Tesla service has been absolutely spectacular. The best, highest World Class service I have experienced anywhere in my life! Unfortunately, that can only go so far
But when things are working as designed, this vehicle is PURE DRIVING BLISS!
P.S. I have had this typed out for over a day now, contemplating weather or not to post it. I don't want to get anyone in trouble, and I don't want to be the subject of "hate mail" again like I was a few previous times I have given my HONEST STRAIGHTFORWARD OPINION BASED ON MY EXPERIENCES. Even then, it was a difficult decision, but I am positing it.
