NHTSA investigating 561k Toyota Prius hybrids for possible steering shaft defect

The Detroit News is reporting that the National Highway Traffic Safety Administration will investigate some 561,000 Toyota Prius models for potentially defective steering shafts. The affected hybrid models are from the 2004-2009 model years. The story indicates that NHTSA is weighing whether or not to grant a defect petition, which claims that Toyota incorrectly assembled the hatchback's steering linkage.
As of this writing, there is no recall. However, a recall based on the Prius steering shaft would be the third related to steering issues for the model since 2006. Seven years ago, Toyota recalled 170K Prius models for potential cracking of the intermediate shafts, and in November of 2012, the automaker recalled 670K units to replace the steering shaft extension assembly.
We'll be monitoring NHTSA's signals to see if this investigation turns into a full-fledged recall. For now, stay tuned.

Vehicles awarded IIHS Top Safety Pick awards skyrockets for 2015 [w/video]

By practically every measure, passenger vehicles in the US are continuing to get safer. With the year rapidly coming to an end, the Insurance Institute for Highway Safety is releasing its annual list tallying of the scores for the latest vehicles to see how they compare to last year. Judging by the agency's evaluations, the numbers look quite positive. According to the institute, 71 vehicles earned either the Top Safety Pick or Top Safety Pick+ rating so far in its testing for 2015. Among the latest winners, there have been 33 TSP+ awards and 38 TSP medalists. That's a healthy increase over the 22 TSP+ and 17 TSP grades in 2014. The figures appear even more impressive when you consider that it keeps getting harder to earn the + designation. In the latest round of testing, a vehicle must offer some form of front crash prevention automatic braking to get the mark. Previously, just a warning to drivers was necessary. This list also illustrates the ways that automakers adapt to new testing procedures. In 2013 there were 117 TSP ratings and 13 TSP+ awards. Then, the IIHS mandated that to be a safety pick, a model had to score Good in the institute's four crash tests, plus a Good or Acceptable in the small overlap front test. That brought a plunge in 2014 to just 17 TSP grades. With the numbers climbing again, companies apparently have deciphered how to perform better. Some brands especially stood out on this year's list. The IIHS praised Volvo, Mercedes-Benz and Acura for offering standard front crash prevention systems on some models. Subaru received at least one of the awards for all seven of its models. Toyota also had seven, and the Honda brand did too – though the institute counts the two- and four-door versions of the Civic and Accord separately. Check out the full announcement below and a video about this year's winners. The full list can be viewed, here. Safety gains ground: More vehicles earn top honors from IIHS The number of vehicles earning either of the Institute's two awards has jumped to 71 from 39 this time last year, giving consumers more choices for optimum protection in crashes. The number of winners in the top tier - TOP SAFETY PICK+ - has increased by 11 for 2015, despite a tougher standard for front crash prevention. "This is the third year in a row that we are giving automakers a tougher challenge to meet," says IIHS President Adrian Lund.
