These disgruntled owners aren't upset about what any of the new features actually do; in fact, they love them. The issue is Tesla's secrecy before the reveal. A few of these folks bought their cars just a few months ago, some even in September, according to The San Jose Mercury News. If the upgrades had been publicized earlier, then they would have waited to order versions with the latest and greatest tech.
Some of them are already on the web lodging their complaints. According to The San Jose Mercury News, the website Change.org has competing petitions asking Tesla to find a way to retrofit the features, which the company says isn't possible, and another requesting the automaker to ignore the complainers.
Among traditional automakers there are usually several months between a new model's announcement, and it actually going on sale. In Tesla's case, the first official teaser before the launch of the D came about a week before the reveal and hinted at something else at the time, which became the A. Should the company have given prospective buyers greater warning that two big features were on the way? Let us know what you think in Comments.
