Where on the forum can a future owner find information related to any issues regards drive trains?
Use volkerize.com to search these forums. Also go to TMC and browse the forums there.
What drivetrain issues? AFAIK there have not been any. AC induction motors last practically infinitely unless you really abuse them. Car around them breaks down first. I don't think I have seen any mentions about electronics or batteries breaking either.
If you are referring to the overly-hyped issues in the news, those were early designs of the car, and they were fixed entirely by a shim placed on the motor mounts, and a Zip Tie on a signal cable going to the motor. All cars produced now have the fixes, and will not have those issues.
Even if you buy one of the first production models that has the issue, Tesla Service covers all of these issues under warranty ($0 cost to the owner) and they are lauded as the best car service in the industry.
You will not find the same reliability in any ICE car, and you will not find better service from any other manufacturer/dealer.
Not to mention that in all but a handful of cases I've heard of the vehicle remained completely usable despite some slight noise or the slight bump caused by the lack of a shim.
Zephod, most of those drive unit replacements you will read about, were replaced proactively. Meaning they didn't fail, there were noises that customers heard and the fastest way to correct the problem was to swap out the whole unit. The drive units were then sent to the factory for further diagnoses. This is the same as a Chevy dealer swapping out an engine due to a valve train noise.
Tesla announces infinite mile warranty for Model S drive units:
Now what were you saying about "issues"?
There been two types of noise, gear noise and inverter noise. Neither one stops the car, but the noise is hard to ignore.
I think it is a design feature. Tesla could have had an idiot light for service that could have been easily ignored, but the annoying noise will get the car into service very quickly.
I now have the noise in my second drive unit...
How would you characterize the noise?
Is it a bad noise? Or just a different sound? Does it have a science fiction-ee sound? Maybe something that might actually make the car hear-able by pedestrians?
Or is it a really bad sound that makes the car sound sick?
I have the 'milling sound' and the 'balloon squeal' but neither are persistent... the 'milling sound' is only audible <30mph but if you're driving slowly near a wall with the windows down it's very obvious. The 'balloon squeal' is only at high power... >250kW. IMO neither is worse than the sound of the quietest ICE :) But a brand new Tesla is DEAD silent... and I think some owners just want that.
