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.

NHTSA may greatly expand GM airbag recall

The National Highway Traffic Safety Administration is pondering whether to dramatically upscale a pair of airbag recalls on General Motors vehicles. The two existing campaigns, one launched in the fall of 2012 and the other in January of this year covered just 6,845 vehicles, but the government agency is considering whether to boost the recall to around 400,000 units.
The existing recalls involve the the closely related 2012 Buick Verano (shown) and Chevrolet Cruze sedans, along with Sonic and Camaro models. The root of the problem is a shorting bar in the inflator module of the steering-wheel-mounted airbag that may contact the primary state airbag terminal, a condition that could prevent deployment in an accident. Dealer technicians have been replacing the steering wheel airbag coils to fix the issue.
According to a post on NHTSA's website, the root cause, said to be a production issue, may not have been completely isolated - particularly for the second recall, which was for the Camaro. According to Automotive News, GM says it is cooperating with the government investigation, but won't say whether or not it knows the true origin of the problem.

Kia leads J.D. Power's Vehicle Dependability Study for 2022

For the first year ever, Kia leads J.D. Power's annual Vehicle Dependability Study with a score of 145 problems per 100 vehicles. Buick (147) and Hyundai (148) round out the top three. The highest premium brand on the list is Genesis, with a score of 148. It's common for so-called "mass market" brands to lead this particular study, according to J.D. Power, as "premium" brands "typically incorporate more technology in their vehicles, which increases the likelihood for problems to occur" and aren't necessarily built to a higher standard that less-expensive brands. The highest-rated single nameplate is the Porsche 911. It's the third time out of the past four years and the second year in a row that Porsche's quintessential sports car has taken top honors. Porsche as a brand sits in seventh place (162) just behind Lexus (159) and ahead of Dodge (166). At the very bottom of the list is Land Rover with a dismal score of 284; the SUV specialist held the same unfortunate distinction on last year's list. Ram (266), Volvo (256), Alfa Romeo (245) and Acura (244) also performed poorly. The overall industry average score sits at 192 — mass market brands average a score of 190 while premium brands sit 14 points lower at 204. While Tesla is unofficially included in some of J.D. Power's results, the agency says the sample size it has access to for this study is too small to include. As has been the case for the past several years, infotainment systems dominate the list of problems reported by owners. Popular (or unpopular, depending on your point of view) complaints include built-in voice recognition (8.3 PP100), Android Auto/Apple CarPlay connectivity (5.4 PP100), built-in Bluetooth system (4.5 PP100), not enough power plugs/USB ports (4.2 PP100), navigation systems difficult to understand/use (3.7 PP100), touchscreen/display screen (3.6 PP100), and navigation system inaccurate/outdated map (3.6 PP100). While problems with the car's infotainment and technology packages are indeed bothersome, it's important to remember that such issues aren't usually leaving owners stranded with an immovable vehicle like a broken transmission or blown engine would. Culling infotainment complaints from the results would reduce the average problem-per-100-vehicle score by a staggering 51.9 points. The vehicles included in this study are from the 2019 model year. That means owners have had three years to get to know their cars and trucks. It's the 33rd year that J.D.
