Curious.
Tesla specifically recommends not to tow with Model S but you do anyway.
Given the nature of your usage, do you think there is any merit to suspension issues due to larger weight on the components?
I was thinking of adding towing capability to our S, but we likely will end up moving to X some day when we want to do towing, so that's why I'm asking.
Not really. My first Model S had same issues. While I had a hitch on it, I actually only used it to tow a trailer 3 times. The first was a log splitter, which I towed about 300 ft, second was a whole house generator, trailer and genset were about 350lbs total for about 120 miles, then the empty trailer home, which weighed in at about 120lbs empty (Very small harbor freight utility trailer, their smallest, which I had also previously towed with 1200lbs on, during a 5,000+ mile road trip with my old 1.8L nissan cube), and last, I cant even remember, I think it was a very short distance and very light.
Now, the P90DL I had as a loaner, also had the SAME suspension issues mine had/is having. HOWEVER, it was not yet as bad, but the mileage was about what, 36,000 miles on that loaner. Same noises.
So my First MS60 was at about 53,000 miles when it had the issues, My 90D was about 43,000ish miles, and the P90DL was about 36,000 miles.
In comparison, I towed with my old 1.8 L Nissan CUBE CONSIDERABLY more then I do now with my Tesla. While I no longer own that cube (The Ex Wife has it, and she beats the royal $417 out of it!), no suspension issues, no transmission issues, no issues at all, accept for all the tires and rims my ex goes through due to hitting the curb....
