Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.

Nissan recalls 3.5 million vehicles over airbag sensor

Nissan is recalling 3.53 million vehicles globally – 3.2 million in the United States – because the front passenger airbag may or may not deploy properly in the event of a crash. In affected vehicles, the occupant sensing system may not properly register a person sitting in the passenger seat. Passenger-side airbags in roughly 622,000 Nissan Sentra models built between 2013 and 2016 may deploy in crashes when they shouldn't, such as when a child is in the seat. 2016-2017 Nissan Maxima, 2013-2016 Nissan Altima, NV200, and LEAF, 2013-2017 Nissan Pathfinder, 2014-2016 Nissan NV200 Taxi, Infiniti QX60 and Q50, 2014-2017 Nissan Rogue, 2015-2016 Nissan Murano, Chevrolet City Express and 2013 Infiniti JX35 vehicles suffer from the opposite problem. In those models, the airbag may not deploy when it is supposed to. Nissan is aware of at least three crashes where airbags in one of the above models did not function properly, resulting in "moderate injuries." There have already been four recalls since 2013 for similar issues in Nissan vehicles. If you own one of these cars, expect a letter from Nissan in short order (or from GM if you own a Chevy City Express).

SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2016-2017 Nissan Maxima, 2013-2016 Nissan Altima, NV200, LEAF and Sentra, 2013-2017 Nissan Pathfinder, 2014-2016 Nissan NV200 Taxi, Infiniti QX60 and Q50, 2014-2017 Nissan Rogue, 2015-2016 Nissan Murano, Chevrolet City Express and 2013 Infiniti JX35 vehicles. In these vehicles, the front seat passenger Occupant Classification System (OCS) may incorrectly classify an adult passenger as a child or classify the seat as empty despite it being occupied. As a result, the passenger frontal air bag may be turned off and not deploy in the event of a crash. CONSEQUENCE: If the passenger frontal air bag does not deploy as intended in the event of a crash, the passenger is at an increased risk of injury. REMEDY: Nissan will notify their owners. Chevrolet City Express owners will be notified by General Motors.

California has sold 102,440 EVs since Volt, Leaf went on sale in 2010

Last July, Plug In America declared that a Mitsubishi i-MiEV in Alabama was the 100,000th electric vehicle sold in the US. Today, the California Plug-In Electric Vehicle Collaborative announced that that many EVs have now been sold in California alone. To celebrate the milestone – which was actually 102,440 EVs sold in the Golden State between when the Chevy Volt and Nissan Leaf were introduced in late 2010 and the end of August 2014 – we spoke with some of the key players in moving the battery-powered metal off of the dealer lots and into driver's driveways. CARB's Mary Nichols drives a Honda Fit EV, and said that in LA, it's no longer "a weird thing." The chairman of the California Air Resources Board (CARB), Mary Nichols, took a broad overview. Nichols herself drives a Honda Fit EV, and said that in her home of Los Angeles, that's no longer "a weird thing." She told AutoblogGreen that, "The industry people that we work with are very clear about this, they think the electric cars sell themselves, in terms of their driveability and attractiveness, if you can get a person into one," she said. "The best way to get a person into one is for them to see it somewhere, and that's really what we're celebrating here. As you get to critical mass, and I think 100,000 vehicles is getting to that point, people start looking at these as an option as opposed to something that they walked into the dealership already wanting to get." Given CARB's support of hydrogen vehicles as well as EVs, we had to ask Nichols when she thought H2 would hit the 100,000-vehicle milestone. She declined to answer that question, but did say that, "Hydrogen vehicles are just beginning to be available in the market. They are just being very selectively and even more cautiously introduced than plug-in vehicles because of concerns that customers will have a good experience, and a good experience means that there has to be an adequate supply of fueling stations," she said. "There has been a lot of expression of interest and support and vision in this direction but we are just at the beginning stages, where we were with plug-in vehicles a few years ago. It's going to take a while." If you ask Nissan's Brendan Jones how a state can support a new technology like plug-in vehicles, he will point to how EVs were rolled out in California. Turns out, the company has learned a lot from selling so many Leafs there.
