BMW broadens engine bolt recall to nearly half-million cars worldwide

Almost one month ago, we reported on a BMW investigation into a potentially defective bolt that lived in the company's VANOS variable valve timing system. At that point, the potential recall was seemingly limited to Chinese-market cars; the company was filing a recall application with Chinese officials.
Today, Bloomberg is reporting that the engine bolt issue has expanded into a recall for several world markets, involving some 489,000 vehicles. BMW was able to verify that report to Autoblog, while also providing a great deal more detail about the issue and vehicles affected.
The recall affects vehicles powered by N55 inline six-cylinder gasoline engines equipped with VANOS and Valvetronic technologies. 1 Series, 3 Series, 5 Series and 5 Series Gran Turismo, X3, X5, X6 and Z4 models from the 2010 to 2012 model years are included, as is the 2012 6 Series.

The troubled Alfa Romeo Giulia needs serious help [UPDATE]

UPDATE: An Alfa Romeo US spokesman responded to this article with the following statement: The safety concerns expressed in the story are false. The all-new 2017 Alfa Romeo Giulia is designed and engineered to meet or exceed all federal safety regulations. The Alfa Romeo Giulia will begin production for the North American market in the late second-quarter of this year. Alfa Romeo will have a full product portfolio of premium vehicles that includes plans for (8) all-new Alfa Romeo vehicles by 2020. The product launches are prioritized by segment volumes starting this year with the Alfa Romeo Giulia production for North America starting in late Q2, followed by the Midsize-UV – the 2nd largest premium segment in North America. Even on the day you dragged them kicking and screaming and gesticulating wildly to a table full of concrete evidence, Alfa Romeo executives will never admit the Giulia program is going through a tough patch. But it is. Reports say the Giulia, on the eve of production, didn't just fail one internal crash test, but failed the front, side and rear impact tests. Alfa denies it. Automotive News published a report last week saying two suppliers had insisted the Giulia, on the eve of production, didn't just fail one internal crash test, but failed the front-, side-, and rear-impact tests. A third supplier source told us the same thing. Alfa is denying it. It was due on sale in Europe late last year and was supposed to be here in the next month or two. But it wasn't, and it won't. It was to be headlined by a twin-turbo V6 that reportedly howled its way around the Nurburgring 14 seconds faster than the BMW M3 could manage. That second part is only true if you believe it's fair to compare a full lap in a standard BMW M3 with a favorable accumulation of sector times to a development prototype Giulia with 220 pounds stripped out of it and rolling on hand-cut racing slicks. No, me neither. A Promising Start The Giulia's all-new architecture was developed in just two years by a skunkworks of young engineers headed by Fiat's engineering prince, Philippe Krief, and (bafflingly) sited inside Maserati's headquarters complex in Modena, about three hours from Alfa Romeo's own Turin HQ.
