While my normal cars haven't had many issues with Tesla besides the things I've previously written about, I do have a situation with a Model X (clean title, supported car co-owned by a friend) that's been modified where Tesla has thus far refused to do some service on it, including some things that should be warranty items. I've been super patient with Tesla on it, and they seem to be working towards a solution, but, time will tell. I've thus far not publicized much detail on this out of respect for the folks at Tesla that have been working with me towards a resolution. However, I am starting to lose patience with the whole situation and will likely have to pursue other avenues for resolution if they don't come through soon.
