A few things need to be cleared up about the supposed safety of Model S suspensions:

First, there is no safety defect with the suspensions in either the Model S or Model X. Since we own all of our service centers, we are aware of every incident that happens with our customer cars and we are aware of every part that gets replaced. Whenever there is even a potential issue with one of those parts, we investigate fully. This, combined with extensive durability testing, gives us high confidence in our suspensions. With respect to the car that is discussed in the blog post that led to yesterday’s news (more on the blog post below), the suspension ball joint experienced very abnormal rust. We haven’t seen this on any other car, suggesting a very unusual use case. The car had over 70,000 miles on it and its owner lives down such a long dirt road that it required two tow trucks to retrieve the car. (One to get the car to the highway and one to get it from the highway to the service center.) When we got the car, it was caked in dirt.

Air pollution has a significant and pervasive impact on public health. According to the World Health Organization, it is now considered "the world's largest single environmental health risk," with more than three million people dying every year as a result. This is more than twice the number of people that die in vehicle accidents each year.

PALO ALTO, Calif. – The National Highway Traffic Safety Administration (NHTSA) has reaffirmed the 5-star safety rating of the Tesla Model S overall and in all subcategories for Model Year 2014, confirming the highest safety rating in America. While Tesla is awaiting feedback from NHTSA regarding their investigation of recent fire incidents, the German Federal Motor Transport Authority, Kraftfahrt-Bundesamt (KBA), recently concluded its review of the incidents, finding no manufacturer-related defects or need for further action.

Palo Alto, CA — Independent testing by the National Highway Traffic Safety Administration (NHTSA) has awarded the Tesla Model S a 5-star safety rating, not just overall, but in every subcategory without exception. Approximately one percent of all cars tested by the federal government achieve 5 stars across the board. NHTSA does not publish a star rating above 5, however safety levels better than 5 stars are captured in the overall Vehicle Safety Score (VSS) provided to manufacturers, where the Model S achieved a new combined record of 5.4 stars.
