Buick takes top spot in 2022 J.D. Power Initial Quality Study

People, economies, and supply chains weren't the only things continuing to get sick over the past year. The 2022 J.D. Power Initial Quality Study (IQS) is out, showing the average rate of problems per 100 vehicles (PP100) during the first 90 days of ownership increased overall. The average figure for the 32 ranked manufacturers in 2020 was about 166 problems per 100 vehicles. In the 2021 IQS, that dropped to an average of 162. This year, the average jumps to 180 problems. J.D. Power says that figure is a record high over the 36-year history of the study. Buick leapt to the top of the rankings this year with the fewest issues, at 139 problems per 100 vehicles in the first 100 days of ownership. After Dodge became the first American automaker to lead the IQS in 2020, followed by Ram in 2021, this year marks a three-peat for U.S. carmakers. Dodge took second this year at 143 PP100, Chevrolet third with 147 PP100, Genesis the first luxury maker on the chart in fourth with 156 PP100. Between February and May, this year's study gathered responses to 223 questions from more than 84,000 new 2022-model-year car owners and lessees. The questions are designed to zero in on real-world problems new owners encounter with nine categories of vehicle features: Infotainment; features, controls and displays; exterior; driving assistance; interior; powertrain; seats; driving experience; and climate. As has been the case in the past few year, infotainment has proved to be the most problematic bugbear making scores worse. Considering features individually, six of 10 of the worst problem areas dealt with infotainment, causing infotainment's score of 45 PP100 to be 19.5 PP100 worse than the second-placed feature. Consumers ranked getting Android Auto and Apple CarPlay to connect reliably as the most troublesome.  GM didn't just score with Buick, which was one of only nine of the 33 ranked brands to show improvement this year. The conglomerate earned first place with the fewest PP100 among all the automaker groups, and scored the most model-level awards with nine, ahead of BMW with eight and Hyundai Group with three.  This year's study again showed a gap between luxury and mass-market makers, thought to be down to the amount of tech in luxury vehicles that consumers aren't properly informed about or that doesn't act as expected — that latter issue exacerbated by the chip shortage.

Stop-start standard in four-cylinder 2015 Chevrolet Impala

Chevrolet has announced that it will include stop-start technology as standard in the entry level 2015 Impala. The result is a nearly five-percent improvement in city fuel economy, also known as one mile per gallon, up to 25 mpg, combined. The 3.6-liter V-6 Impala will not feature stop-start. The 2015 Impala comes equipped with Chevrolet's 2.5-liter Ecotec four-cylinder engine, which will also offer 22 mpg in the city, and 31 on the highway. The 3.6-liter V-6 Impala will not feature stop-start and the mild-hybrid eAssist model from the 2014 MY, which got 29/25/35 combined/city/highway mpg, has been discontinued. Chevrolet spokesman Chad Lyons told Green Car Reports that not even one percent of the 2014 Impalas purchased were the Eco model. So Chevy is trying something different. With a seamless driving experience in mind, the new Impala's stop-start tech features software that governs under what conditions the feature will activate. The engine won't shut off if the car has not reached a speed of six miles per hour, so the start-stop won't be cycling during traffic jams. It can also fire the starter even if the engine has not come to a full stop, which quickens reaction time, particularly in instances of what Chevrolet calls "change-of-mind events." The stop-start function uses information about cabin temperature and humidity as well as battery charge to help determine whether or not to shut off the engine. The 2015 Impala has been engineered to reduce NVH, which will also help create a smoother stop-start experience for occupants, Chevy says. Motor mounts have been updated, and a burlier starter motor will help restart the engine after a stop. The Impala follows the 2014 Malibu as Chevrolet's second vehicle to feature stop-start tech. The four-cylinder model currently makes up over 30 percent of Impala sales. The 2015 Impala will be available beginning this summer, with a base MSRP of $27,735 (including destination charges). And while one MPG isn't a huge difference, neither is the price increase of just $50 for a bit of eco-minded innovation. Read on for more details in the press release below. Chevrolet Makes Stop/Start Standard in 2015 Impala Technology improves city fuel economy by 5 percent 2014-05-22 DETROIT – Stop/start technology will be standard on the 2015 Impala base 2.5-liter ECOTEC® engine, an addition that improves the vehicle's city fuel economy by nearly 5 percent, or one mile per gallon.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.
