Nissan Quest under investigation for inaccurate fuel gauges

After receiving 12 complaints in the last 14 months, the National Highway Traffic Safety Administration has begun a preliminary investigation into a fuel gauge issue with the 2007 Nissan Quest. Drivers have reported that the fuel level gauge will show there's gas in the tank when there actually isn't - in two cases, the digital distance-to-empty gauge indicated more than 70 miles of remaining range - and it will stall out.
This is the second time the 2007-model-year Quest has been involved in the same fuel gauge issue. In 2010 Nissan recalled seven models, including the Quest, from the 2005-2008 model years because of faulty fuel readings. The 12 vehicles in this latest complaint could have slipped through the cracks then, but we'll find out more when NHTSA updates its progress with the investigation into the estimated 37,656 units.

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.

Renault, Nissan attempt to calm rumors of impending split

TOKYO/PARIS — Shares in Renault recovered some lost ground on Tuesday after the French carmaker and its Japanese partner Nissan rejected media reports that their alliance was in danger of being dissolved. Some have openly questioned whether the alliance can survive without disgraced former CEO Carlos Ghosn to keep the two partners happy.  Renault shares fell to a six-year low on Monday after rumors circulated that its alliance with Nissan was in jeopardy. Nissan shares tumbled to their lowest in 8 1/2 years on Tuesday in Tokyo. At the opening of trading in Paris on Tuesday, Renault shares rose 1.3 percent, before falling back slightly to trade up 0.49 percent by 08:23 GMT. The alliance, which also includes Japan's Mitsubishi Motors, is "solid, robust, everything but dead," the chairman of Renault, Jean-Philippe Senard, told Belgian newspaper L'Echo. A split between the two automotive giants would force both to find new partners in a fast-consolidating industry that is growing increasingly difficult to navigate for independent companies. It will be especially difficult for Renault and Nissan, whose dirty laundry Ghosn intends to air for public consideration.   French Finance Minister Bruno Le Maire also weighed in, saying reports some executives wanted to break up the alliance were "malicious." Speaking to France's CNews TV, he also said he expected Renault to name a new chief executive within days to replace Thierry Bollore, a Ghosn-era appointee who was ousted in October. Luca de Meo, who stepped down as the head of Volkswagen's Seat brand last week, is seen as a frontrunner for the job, although a stringent non-compete clause in his contract firm may prove a hurdle, sources have told Reuters. Nissan, in response to "speculative international media reports," said it was "in no way considering dissolving the alliance." "The alliance is the source of Nissan's competitiveness," the Japanese automaker said in a statement. "Through the alliance, to achieve sustainable and profitable growth, Nissan will look to continue delivering win-win results for all member companies." Concerns emerged about the future of the Renault-Nissan partnership after the November 2018 arrest in Japan of Ghosn, the man who did more than anyone else to hold together the disparate alliance of often-contrasting carmaking cultures.
