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.

GM recalls nearly 24,000 Buick Regals for brake issue

Buick is recalling 2018-2020 model year Regals to address a software defect in the braking system that would result in a loss of power assist under certain circumstances, making the brakes difficult to operate and potentially leading to a crash. In total, 23,734 models are covered by the campaign. "In the event of a partial or full loss of vacuum-brake assist, the vehicle’s hydraulic-brake boost is designed to supply supplemental pressure to the vehicleÂ’s brake system. A software error in the electronic brake control module (EBCM) may fail to activate the hydraulic-brake boost under these conditions," GM said in its defect report to NHTSA. "If the vehicleÂ’s vacuum-power brake assist partially or fully fails, braking events may require additional stopping distance, depending on the brake pedal force applied by the driver. Increased stopping distances could increase the risk of a crash." GM says that a warning indicator will illuminate in the dash if the system completely fails, and drivers may notice an increase in brake pedal resistance. Failure will not render the brakes inoperable, but they will require more force to operate. GM has begun notifying dealers of the defect; owners should be notified starting in August.   Related video: Recalls Buick GM Safety Hatchback Wagon Sedan

2014 Chevy Malibu, Buick LaCrosse recalled over brake mix-up

The recall madness over at General Motors isn't letting up anytime soon, as evidenced by this latest call-back of 8,208 Chevrolet Malibu and Buick LaCrosse sedans. For those keeping track, this is the fifth recall that GM has announced in the past two weeks, not to mention the massive ignition-switch issue from earlier this year.
GM issued a statement saying these sedans are being recalled due to "possible reduced braking performance," according to Automotive News. The problem? Rear brake rotors may have accidentally been installed in the front brake assembly. And since both cars use more robust braking systems up front than out back, braking power could be reduced, increasing the risk of a crash.
Automotive News reports that, of the over 8,000 cars being recalled, about 1,700 are currently in the hands of customers, while the others are still in dealer inventory. GM is unaware of any crashes or injuries related to this problem. All of the affected vehicles are from the 2014 model year.
