Looking back, "widespread" was not the right choice of words, as every car with air suspension which updates to FW5.8 will have the lowering issue. However, what I am arguing is that the possible over-sensitivity of the charging rate limiter is a more serious issue (and has a more detrimental effect on the Tesla ownership experience) than the suspension issue, even if fewer cars are affected. Having the charging rate cut by 25% at random charging locations will make planning a long trip (one of the key factors in my decision to purchase a Model S was its range) a real chore, as you won't be able to accurately plan your charging because you won't know how fast you will charge at a given location.
Please keep in mind that I am not against the charge-reducing feature in principle. It just sounds like it may be a bit over-sensitive in its initial release and is limiting the charge where there is no actual safety risk. As I said in my previous comment, I hope Tesla can refine this feature to weed out any false positives. IMO, a possible unnecessary 25% reduction in charging rate trumps the car not lowering at highway speed.
